Direct broadcasting satellite signal transmission system

[Detailed Description of the Invention]

the present invention -- a video distribution network -- and -- furthermore -- if it explains in full detail -- reliability is there for microwave, a cable, the video signal used especially for 1 direct broadcast satellite communication, an audio signal, and a control signal -- it is related with a safe transmission method. A pay television, a conference call, telephone Seminar, a private broadcast network, etc. are included in direct broadcast satellite service. It is small for several years these days, and since the television receive only terminal device of budget prices can be obtained, the demand for the above-mentioned service is growing. The increase of demand to direct broadcast satellite service is further expected as reception-only television antenna technology is improved and the price of television receive only terminal devices falls. The present invention is indicated about a direct broadcast satellite method for this reason. However, the principle about the present invention is applied also to the communication method of other kinds like the cable used now and a microwave method, and the method of various kinds developed now. Unlike Land line and a microwave link on land, privacy lacks in satellite transmission. This satellite transmission is receivable with any TV receive only terminal devices which have the antenna located so that that satellite signal might be received. Therefore, since safe transmission of video, an audio, a programming signal, and a data signal provides privacy important for many uses, it is needed. The easy example of the direct broadcast satellite network where safety is demanded is a network which broadcasts a television signal. Since the arbitrary receivers which have an antenna to a broadcast signal zone can receive a satellite signal, they need to code the satellite signal by the method of decrypting, only by being a member's Reception unit busy. K and other members have paid the price to other programs or program groups. Therefore, although the member who paid speaking to the specific program or the program group can receive it, a satellite signal must be coded so that other members cannot receive it. Probably a program with a specific member will be checked and it will be desirable to design a method to determine whether to be desiring to follow [ whether he wants to view and listen to the program then and ], and to pay a price to the right of viewing and listening. It pays by such request viewing and listening (IPPV), and in a method, a member's determination must be recorded in order to carry out a suitable claim, and it must be connected to a claim device. In such a case, in order to eliminate the possibility of tapping of the To 2 screw, the control signal to the member receiving unit which directs how the claim authorities are contacted to a member receiving unit must be safe. the method of the present invention transfers the complicated mechanism of a device to the direction of a network transmitting end -- on the other hand -- a receiving set -- cheap -- and reliability is there state Busy -- it is designed like. The present artificial encoding technology is used in order to provide the safe transmission method for broadcast signals. A video signal is processed and is transmitted by analog format. An audio signal is digitized and is transmitted in digital data form. The control data in which an address is possible is systematized to a packet according to an address, and is transmitted in the same digital data form as an audio signal. All these signals are together put by baseband using Time-Division-Multiplexing art. It modulates and this baseband signal put together is transmitted to a member's receiving unit via a satellite link. According to this signal structure, the necessity for the subsubcarrier for a sound and control data is lost, and the change of a video signal increases, and it can improve the opposite noise ratio of a video signal. Since all the signals are multiplexed in time by baseband, only one FM demodulator is only needed for the receiver for all the signals. Two audio channels are broadcast. In charged TV Sasa-A, both this audio channel is applicable to stereo sound broadcast. Other uses can constitute one of audio channels as a data channel for service like transmission of a text, a message, a facsimile, etc. A general Busy and transmitting end device consists of a program manipulation unit and a real time controller. This program manipulation unit performs digitization of processing and the Scramble ring of a video signal, and an audio signal, encryption of that audio data, and multiplexing by the time of a baseband signal. A real time controller generates an audio cryptography key, enciphers the control message in which an address is possible, generates a packet message according to a transmission protocol, and maintains a user's database, and communicates with other processing units. Each receiving unit has the address possible controller decoder designed so that it might be used with a receiver, and the receiver has an interface required in order to carry out an interaction to the decoder. Demultiplexing of the address possible controller Decorator baseband signal is performed, a receiver is controlled, desk rambling of the video signal is performed, and audio data is deciphered, and the audio data is changed into an analog form. The compound television signal transmitted uses the format which has a portion an effective video portion and during the horizontal blanking. The digital audio channel and control data channel of 22 break a part of horizontal blanking period, and, in addition, shine. Video frame synchronization-ized information and a zero level standard are transmitted to a vertical blanking interval. Audio data and control data are transmitted in burst synchronous mode. 2 level video Scramble ring method is used in order to acquire the best combination of performance, a price, and safety. The first level is attained by removing the synchronization pulse of a line and a frame from a video signal completely. And the only synchronization word is transmitted to a vertical blanking interval for the object of synchronization. An address possible controller decoder establishes synchronization by checking in search of the synchronization word. Once the synchronization word is checked, all the synchronization pulses will be reproduced about the synchronization word. This art is used with reversal of the video signal which is the 2nd safe level. In order to avoid degradation of image quality, reversal of video is performed per scene change / frame. An order of the video reversal is controlled by 2 Advance bit stream at a transmitting end. The bit stream in same is used for eye Running recover the inversion signal at a receiving window end. The bit stream of the 2 Advance is obtained from a synchronous stream cipher. The key for this synchronous stream cipher is changeable for every transmission period. Video reversal can be controlled by a transmitting end, and can be changed also during the communication. Dolbey of San Francisco who attains the performance level which needs the present invention for digitization of an audio It was developed by lab Latries (DolbyLaboratories), new is carried out, and a Itta modulation method is used. Simultaneously, this modulation method needs use of a comparatively cheap decoder at a receiving end. Unlike a video Scramble ring, a very safe audio cipher system is comparatively cheap, and can attain. In the decryption circuit of a digital type, the whole can constitute half-custom-made Also using a custom-made integrated circuit. In the cipher system used, the error transmitted is zero, i.e., as for me, a very important thing hears that only a 1-bit error arises by the bit stream by which the 1-bit error of the enciphered bit stream was deciphered. The encryption method which combines the bit stream which occurs with a stream cipher using exclusive OR operation, and a clear audio bit stream is used for this method. A receiving end deciphers an audio bit stream using the bit stream of the same stream cipher. The bit stream of this stream cipher occurs by the key (common audio key) and an initialization vector. A common audio key is used during a communication period, and is transmitted in the form enciphered via the control data channel. An initialization vector is used for the period of each frame, and is transmitted to a horizontal blanking period in a clear form. The encoding technology used by the direct broadcast satellite method of the present invention is about details further, The fundamental method is indicated, The title of an invention "cryptographic system Fau Direct broadcasting Satellite Network (Cryptographic) Donald of System For DirectBroadcast 5atellite Network J It applies in the name of a phon (Donald 1orne) on October 26, 1984, and is U.S. Serial Number 665.114 under present pendency, And it was turned to some of the improvement, The title of an invention "Kryptk Rafik system Using The Inta changer pull Key Brux And Selector bull Key Flag face J (Cryptogr&phic) Syatem UsingInterechangeable Key Blocks and 5electablsKey John of Fragments A chef ground (John Jeffers) and Donnalt Please apply in the name of Static-A (ponald Horne) on March 11, 1985, and refer to U.S. Serial Number 710.385 under present pendency. These the applications of both are transferred to the grantee. An address is possible. A control data channel conveys the information about secrecy like the decryption key of an audio, and a permit stage level. This method is designed to prevent a tapping person from receiving this information correctly, and prevent receiving the information beyond the information to which the just terminal person was permitted. The cipher system used by the present invention uses the concept of a multiplex terminal key. A common audio key is enciphered by the method of being different, respectively so that it may be used with each receiving terminal. In this way, when a decryption key is invaded (this is not not much possible), it is Thing which removes this decryption key, and can prevent damage quickly. An address is possible. Control data is systematized and is enciphered using the key enciphered by a block cryptographic algorithm. The block cryptography key is 64 bits in length. As compared with the conventional data encryption standard (Data Encryption 5tandard), this block cipher has a bigger block and a longer key. Remarkable efforts will be needed even if it tries to solve [ Did it carry out? ] this code forcibly. I hear that one of the important features of the present invention can control the specific function of each receiver unit by real time from a transmitting end. Generally this is attained by use of the data stream which forms a part of compound television signal distributed by a satellite and in which an address is possible. This data stream has a portion possible [ an address ] and receivable only with that receiving unit to a specific receiving unit. Each address possible portion contains one of the different messages of a plurality of. Each message includes the command which controls the function of a receiving unit by which an address is carried out. For example, which programming stage is permitted to viewing and listening per member or which programming stage being suitable for the payment processing outside request viewing and listening, and the receiving unit by which the address was carried out about about can be advised on a message. Since the information included in the message can be changed in real time, the system operator can greatly perform this method and control of especially as opposed to operation of each receiving unit. Thereby, the method of the present invention will become still more flexible, and can provide the individualized suitable service for a specific member better. Since a receiving unit processes the information on video and an audio and is reproduced, other important features of the present invention are related with the method of catching and using control data. The compound television signal includes the information about several programming channels or stages of frequency where each differs. The signal relevant to each frequency contains the data stream containing video information and an encryption portion and in which an address is possible. Selection of a program includes the information about the program as which corresponding frequency aligned with and video and audio information were chosen. This information is used with all the receiving units. Each address possible portion includes the control for a unit address and its receiving A message unit by which the address was carried out. Each header is investigated, and the information in [ including program pertinent information, synchronization information, and the payment information outside request viewing and listening ] it is caught and recorded. When a header contains the group address which shows that the address possible packet by which an address is carried out to a receiving unit may exist and which is equal to the group address of a receiving unit, each address possible portion is investigated one by one. The following header is supervised after all the address possible portions are investigated. If the address possible portion containing an overall address, i.e., the address of a receiving unit, is found, the control information in it will be caught. This control information has a form of a message as mentioned above. The message has the usually enciphered form. The address possible portion includes the information used for decryption of the message, when used with the information memorized by the receiving unit. Control information and program pertinent information are memorized in order to use it for the processing and playback of video and audio information which are displayed. whether [ that the selected program reserves ] -- or viewing and listening outside pays, and see and come out only in an attitude -- it will depend for whether being To or not and a member has to stop having to input a command required for a receiving unit in order to obtain a display Off, therefore the main objects of the present invention are to provide a safe transmission method reliable [ video, an audio, and for control signals ] in a communication method. Other objects of the present invention are to provide the direct broadcast satellite signal transmission method using the address possible data stream inserted in a horizontal blanking period. The object of further others of the present invention is to provide the header packet accompanied by a plurality of address possible packets with the direct broadcast satellite signal transmission method which systematizes an address possible data stream. The object of further others of the present invention is to provide the direct broadcast satellite signal transmission method which can change the information on the address possible packet of a data stream in a real-time attitude. As for the object of further others of the present invention, the header packet of a data stream receivable with all the receiving units is synchronization information, It is providing the data relevant to the program broadcast, and the direct broadcast satellite signal transmission method which pays by request viewing and listening relevant to the program broadcast, and contains data. Permission of the member of each [ packet / of the data stream which can decrypt the object of further others of the present invention only with the receiving unit by which the address was carried out / address possible ], It is providing the direct broadcast satellite transmission method which controls the rediscount reliance of distribution of a cryptographic key, viewing-and-listening part payment processing, and channel frequency, and controls other functions of the receiving unit by which an address is carried out, and the display which it-Related directly. The object of further others of the present invention is for the address possible packet of a data stream to provide the direct broadcast satellite signal transmission method which controls an interface with the peripheral equipment of a receiver. According to one mode of the present invention, the method for transmitting data with the communication method of a type including a broadcast signal generation means, a plurality of broadcast signal receiving means, and the means for distributing a broadcast signal to each reception means from a broadcast signal generation means is provided. This method includes the stage of generating the broadcast signal which has an effective video signal portion and a horizontal blanking portion. It is generated and an audio signal and a data stream are inserted in a horizontal blanking portion. The data stream contains the group of the header portion which comprises group address information and program pertinent information applicable to all the reception means, and the address possible portion relevant to this header. This address possible portion carries out the address of the specific thing (wholly [ when that address is overall ]) of the receiving unit of the group by which the address was carried out, and it includes the information for controlling that function. This gentleman is and an address possible portion are chosen, and it further has the stage of changing the information in it. Thereby, each receiver is controllable by a real-time attitude at a transmitting end. The information on a header includes the information relevant to the effective video portion of a broadcast signal. For example, this information can include video synchronization information and program identification information. It may be related with the desk rambling of an audio again, and may include the decryption information on an audio. This information may be paid by request viewing and listening again, and may contain data. Each reception means is assigned the peculiar digital address containing the bit (group address) of the top beam, and the bit (address of a member unit) of the lowest beam. The information on a header contains the bit of the top beam of the digital address. The information on an address possible portion contains the bit of the lowest beam of the address of the specific reception means to which the address possible portion relates. All the receiving units can be simultaneously accessed using an overall member address. The information on each address possible portion contains that as which it was chosen of a plurality of enciphered receiver message form. The information for [ this ] being chosen and enciphering an optical message form is included as directions of message form. For example, the message of one form can contain the audio decryption data of the command for memorizing program authentication data and this data, and an addition. It can contain the data showing the "home channel" which should be chosen again when a decoder is in stillness mode. Each reception means can also be provided with telephonic-communications capability with a broadcast signal generation means. In this case, one of the message form can have request viewing-and-listening part payment processing data, duration-of-call data, and program value data. Program stage disturbance data and telephone calling-in (call-in) number data can be included in it. The specific program channel of the message of other form is a transponder. [It can have a channel rediscount reliance table used when it must be broadcast on the frequency which is not usually used for failure of a transponder. The information on an address possible portion can also contain elimination for operation of the display control data for controlling the digital display of various receiving units, and a receiving unit, reset control facility data, program disturbance data, an audio, and the Threshold data of data. In a certain case, a receiving unit is used with one or more peripheral equipment for processing of broadcast signal information, record, or a display. One of the message form can contain the data of peripheral equipment. The selection data of peripheral equipment can be included in another message form. I hear that the error of the information by which one of the advantages of this method is contained in one address possible portion is not processed depending on receiving units other than the specific receiving unit related to the address portion containing this error. Therefore, an error does not destroy the function of a method and destroys only the function of the specific receiving unit of this method. According to other modes of the present invention, the method for processing the data received by the broadcast signal of the kind containing an effective video signal portion and a horizontal blanking portion is provided. The horizontal blanking portion contains the audio data portion and data stream which were enciphered. Data streams are group (group) address data and signal synchronism-ized data, And the header portion containing the audio decryption data of the 1st kind include information applicable to all the receiving units, And it has a portion in which each includes information applicable to the control of a receiving unit with a specific group by which an address is carried out containing unit address data, the enciphered message data, and message decryption data, and by which an address is carried out and in which a plurality of addresses are possible. It determines whether group address data of this method corresponds with the group address of a receiving unit, and in order to obtain the synchronization data for the video portion of a broadcast signal, and the audio decryption data of the 1st kind, the stage of processing header information is included. When group addresses coincide with each other with each other, it is determined whether each address possible portion is examined one by one, and the address's of the received receiving unit which is contained in it corresponds with the address of a receiving unit. The information on an address possible portion with the address of the receiving unit in agreement is processed in order to obtain the enciphered message data and to carry out the decryption. The message data contains the audio decryption data of the 2nd kind. The audio decryption data of the 1st and the 2nd kind is used for decryption of Image signal data. According to the mode of further others of the present invention, the receiving unit used with a communication method is provided. This communication method is a thing of a kind which transmits the signal containing a header portion including the video for a program, audio information, a group (group) address, synchronization information, and the information relevant to that program, and a plurality of address possible portions in relation to that header portion. The address possible portion includes the information about the control of a receiving unit of each of the group (group) by which an address is carried out by which an address is carried out. The receiving unit includes the means for choosing the means and the program which should be investigated for receiving the signal. The means for aligning with the frequency of the selected program is established. An address possible portion is separated from video and audio information, and in order that a receiving unit may determine whether enter into the group by which the address was carried out, the means for investigating a header portion is established. The means for catching and memorizing header information is established. In order to determine whether a receiving unit is in the group by which the address was carried out, the means for investigating each portion by which the address was carried out is established. When the address of the receiving unit is carried out, the means for catching and memorizing the control information on the portion by which the address was carried out is established. The means for processing and displaying video and audio information according to the header information and control information which were memorized is established again. Audio information exists in the enciphered form. Control information includes audio decryption information. It is better for processing and a displaying means to have a means for decryption of audio information according to the audio decryption information caught from the portion by which the address was preferably carried out to the receiving unit. Each of the portion by which an address is carried out contains the message. A useless means to catch and memorize control information has a means for catching a message. A message is transmitted in the enciphered form. The portion by which an address is carried out includes information further for decryption of the message. The receiving unit has further a means for deciphering a message using the decryption information on the portion by which an address is carried out. The means for memorizing the decryption information on a message is established. The means for using the decryption information on the message remembered to be the decryption information on the portion by which the address was carried out for decryption of the message is established. One of the portions by which an address is carried out may also include the control information by which an address is carried out to all the receiving units of the group by which an address is carried out. Further, the receiving unit has a means for catching and memorizing the control information in the portion by which an address is carried out on the whole [ the above ], when a receiving unit is one of the groups by which the address was carried out. The present invention is explained by detailed explanation of the following taken into consideration with an accompanying drawing (here, a similar number shows similar parts) in full detail so that it may correspond to these object and other objects. Drawing 1 shows the outline of the direct broadcast satellite network using the signal transmission method of the present invention by a block diagram. This direct broadcast satellite network has one of the satellite which has a plurality of signal transponders indicated to be B in the transmitting end or the head end, and the whole which were indicated to be A in the whole and a plurality of receiving units indicated to be C in the whole, or the terminal units. The signal which occurs at transmitting end A is transmitted to satellite B, and is distributed to a plurality of receiving unit C placed in the signal broadcast zone after that. This signal transmission method can maintain a member, and each 16 million or more effective program channels and stages of a plurality of. Real time (real time) controller 10 receives a real time input from studio control computer 12 locked in time by the start portion of the contents of a program received from ten program inputs of each. Each program input is the standard video amended in a hourly base. It can have a baseband audio in a monophonic recording relevant to this program, 2 power languages, or a stereo. Real time controller 10 receives data input from business center computer 14 which treats a customer database again, and audio response unit 16 used by the field service personnel or the permitted contractor. Real time controller 10 receives an input from head end operator console 18. This head end device receives a program input from studio control computer 12. It carries out the Scramble ring of the video signal again, and enciphers an audio signal. And a head end device supplies the audio signal enciphered as the video program with indispensable data by which scramble was carried out to rise ring device 20. Rise ring device 20 transmits a signal to satellite B via antenna 21. The main functions of real time controller 10 are generating the address data stream carried out in a program manipulation unit 24 Heart arrangement via the computer interface module which forms a part of this controller. An addressing data stream is inserted in the horizontal blanking period of a video signal in program manipulation unit 24. Real time controller 10 remembers request viewing-and-listening part payment information extensible to 16 million decoders to be an authorization list of an address possible controller decoder to a disk memory. This information is To be sent to a different program channel. The menu drive option for real time controller 1oFi and a system state, The usual display of the contents of the system program is supplied to the remote console and local target which were connected by the communication link with statistics and change of both a system parameter and memory information to head end operator console 18. This operation method has a console printer (not shown) for this system other than a head end operator's useless color visual display terminal. The computer interface module of real time controller 10 gives the reserve channel of a plurality of two channels of operation to program manipulation unit 24. The channel of each reserve can be used instead of any one of the channel of this of operation, when one of the channels of operation breaks down. This is automatically attained in real time controller 10. Program manipulation unit 24 provides rise ring device 20 with a channel, and this rise ring device 20 is connected to antenna 21. this system can be supervised by an operator by local or remote both with an operator - To -- it is designed like. Head end operator terminal unit 18 and the remote operator terminal unit are formed for these object, respectively. By control, the scrap ring for the safety of a video signal is attained by removal of a synchronization pulse, and reversal of a video signal. Program manipulation unit 24 is an actual scrambler portion of head end A. Removal of a video synchronization pulse is attained by removal of the horizontal synchronization-ized portion of a video signal. Reversal of video is attained by electronic reversal of a video signal. it gives up for encryption of an audio to digitize a double audio channel and process it by the encryption algorithm on the basis of a key -- it is attained. Next, the obtained encryption digital audio bit unites with control data. The digital bit stream which considers it as a result and arises is placed during the horizontal blanking of a broadcast video signal so that it may be transmitted via a satellite link. Program manipulation unit 24 interfaces with real time controller 10 via a computer interface module. Real time controller 10 has the capability to change control data by a real time method so that the function of a specific receiving unit may be controlled. The member receiving unit of a video distribution network or terminal end C (one of them is shown in Drawing 1 in diagram) has receiver 30 by which interconnection was carried out to address possible controller decoder 32 and television 33. Receiver 30 is connected from low noise block converter feeding 36 and cable 34 which form some antennas 38 attached to the roof of Bill Song. Receiver 30 and decoder 32 are the name "receivers of an invention. the Wiz -- interface Fau Interaction the Wiz -- decoder Controller pull (Receiver) It is With Interface For InteractionWith Controllable Decoder J and they are a Ashock decoder (Ashok George) and John Jefferds (John) on November 3, 1983. Structure and a function are indicated in U.S. patent application pipe No. 548.357 connected now it applied for in the name of Jeffers. Still more detailed explanation of operation of that receiver and a controller had this patent application referred to. Generally the receiver includes the circuit modulated in order to align with the signal given from the received signal and to see this signal that aligned. Since operation of a keyboard is answered and an input order signal is generated, a keyboard input is provided. The display is provided in order to show the seal showing various functions of a receiver. In order to receive an input order signal from a keyboard and to control a tuned circuit and a display circuit, the control circuit is connected usable to the keyboard. This control circuit can generate and receive the data signal about the function of a tuned circuit and a display circuit. The interface is connected usable to the control circuit and address possible controller decoder 32 so that transmission of a bidirectional data signal can be performed between a control circuit and address possible controller decoder 32. A control circuit generates a synchronization signal and transmits this synchronization signal to address possible controller decoder 32. A control circuit will be in a waiting state for a fixed time, in order to receive a data signal from address possible controller decoder 32. Next, a control circuit generates the data signal for starting address possible controller decoder 32 and communication, when a data signal is not received from address possible controller decoder 32 in the waiting period. The control circuit has a memory for memorizing the information relevant to a tuned circuit and a display circuit. The control circuit has a means for accessing a memory, and acquiring the information in it, and changing it into a data signal. a waiting period -- address possible controller decoder 32 to a receiver -- a data signal -- reception -- as for h To case, tcB and a decoder signal are first memorized by the memory. The circuit for changing the received data signal into the suitable form for memory is provided. The memorized information is used from a receiver, in order to control the function of a tuned circuit and a display circuit after that. The data signal from address possible controller decoder 32 can serve as a command to the receiver which generates a specific data signal by response, for example, in order to tell address possible controller decoder 32 about the tuning frequency of a tuned circuit. After a response, since address possible controller decoder 32 traces operation, for example, a channel, for the function that a receiver is specific, again, it can generate a data signal including the command to which a tuned circuit is aligned with different frequency. The data signal with which address possible controller decoder 32 was transmitted to Control circuit can also contain alternatively the data word showing the command which answers viewing-and-listening part payment processing, and sets up a tuned circuit, the command which sets up a display circuit, or the command which disregards a specific dagger command. The data signal generated by the control circuit can contain the data word showing the state of an input command, a display circuit, or a tuned circuit. These data words are used by address possible controller decoder 32 as information in the case of constituting the occurring data signal. Each data signal has a data word containing a start portion, a data part, and an end portion. Especially transmission of a data signal is usually started by the control circuit via generating and the interface of a synchronization word by a control circuit by transmission to address possible controller decoder 32 of the synchronization word. Reception of the data signal by a control circuit arises, only when the data signal from address possible controller decoder 32 is received within a fixed waiting period after generating of a synchronization word. Transmission of the data from a control circuit can be started following the waiting period, if the data signal from address possible controller decoder 32 is not received within the waiting period. The data word generated by the control circuit is mutually separated by the waiting period which can receive the data signal from address possible controller decoder 32. Therefore, a series of specific communication protocols must be protected between a receiver and address possible controller decoder 32 for transmission of a day honor signal. A price is paid by the member and the member can leave directly the desk rambling of the program which is not within the limits of the usual request-to-print-out-files service to address possible controller decoder 32 with other Busy of the usual request-to-print-out-files service provided for a member, and a receiver. This is called request viewing-and-listening part payment processing, and when a key is pressed by a keyboard at the right order, it is attained. in order to see a program, the time window which a member can make a contract of is stopped to a system operator -- it is set up and consists of preliminary-inspection time of the show, and actual time. All the users can have the same preliminary-inspection time, when a program starts, or preliminary-inspection time can also be made into the specific time after a user investigates the program. A member is told that this program can be used by a permit when it aligns with the program which is in a show time preliminary-inspection time again. When a member inputs required permit information, a program has a Scramble ring canceled so that it can see. Address possible controller decoder 32 gives the method for preventing viewing and listening without permission of the program by which scramble was carried out to the member. That is, the member can record freely the peculiar bus code which pays by request viewing and listening and is needed for permission of viewing and listening of a program. It is inputted into the keyboard of a receiver and a bus code is non-volatile RAM (it is transmitted to the decoder of random access memory], and memorizes.). Then, a bus code must be inputted into a receiver in order to see the event by which scramble was carried out. A receiving unit has the control capability to enable disturbance of a program which is based on a system operator or is locally chosen by member again. This control capability is provided by this address possible control decoder 32 when address possible controller decoder 32 is connected to a receiver. The broadcast signal has a plurality of programming levels called the stage. Selection of the program under the not suitable, i.e., are local, control facility for a family viewing and listening will display a channel designator on a display with the suitable display of a control facility. Then, the scramble of the screen is carried out and an audio will be in a silence state. The control bus code which a member needs in order to see this program must be inputted. When a suitable local control bus code is not inputted, a program does not have a Scramble ring canceled, and it cannot view and listen to it. A control facility can also be performed by a system operator. The system operator can choose from a transmitting end so that viewing and listening of the arbitrary stages by a specific member may be prevented completely. About the details of the method of attaining this, it was transferred to the grantee of this application, The title of an invention "program blocking method Fau Use Inn Direct Broadcast Satellite It is a system" (Program Blocking Method For Use 1nDirect Broadcast 5atellite System), and he is Donald. R, A phon (Donald R, Horne) refers U.S. Serial Number 710,466 under present pendency of March 11, 1985 application. A member chooses the programming stage which should pay a price by request to print out files. Other stages of all the are paid the price "responded to viewing and listening." The program stage which is a part of request to print out files is memorized by the permit list of address possible controller decoders 32. A program can be seen when arbitrary program stages are in agreement with the stage of a permit list. Otherwise, since the program of the stage where the display was chosen must pay a price, a member checks, and if he is a request, he shows that a price can be paid to the program. This program cannot be seen when a program is in the stage which appears in "disturbance" list. A permit list and a disturbance list are under a system operator's control, and it can change them by a real time method. In this way, the system operator can always change these lists at the time of necessity or a request. The receiving set has the feature of tracing a channel again. In order to deal with a problem [ like / usual / failure of the specific transponder of the interference to the satellite signal with which a specific program must be broadcast on different frequency, or a satellite ] in which this feature is, a system operator is the method of being made to do Stoppage of a channel for the second time dynamically. In order to carry out this, it is confirmed whether the selected channel traces address possible controller decoder 32 again, and is shown in a table. If the channel exists, a receiver will be told changing channel frequency by address possible controller decoder 32. The channel up to 16 pieces can be put on this table by a program generator, and when it is versatility, it can be changed. Low Misdirection prevention converter 26 receives 12 GHz signal in the input. This signal is mixed with the signal which was amplified and was generated by the oscillator. The signal which arises as a result is an ultrahigh frequency frequency signal, and this signal is sent to the input tuning section of receiver 30 with coaxial cable 34. Aside from this input tuning section, the receiver has an input/outputting part, a control part including a data-communications interface, and a signal modulation part. These each part and all its component are formerly the things of a design except for the portion which has a receiver alignment means of a statement, a control means, and in-series Bach in above-mentioned U.S. Serial Number 548.357. As explained in full detail to U.S. Serial Number 548.357, the input tuning section of a receiver has the zone filter connected to the input part of a mixer. Other inputs of this mixer are supplied by the circuit which sets up an intermediate frequency. This circuit has a multiplication circuit. The input to the mixer is connected to the output of a voltage controlled oscillator. This voltage controlled oscillator is controlled by the output of the charge pump arranged at the control part of a receiver. The output of a voltage controlled oscillator forms the input to a part circumference way, and the circumference way is connected to the input of the electronic switch of the control part of a receiver at this rate. The output of the mixer is connected to the input part of an automatic-gain-control (AGC) circuit via the intermediary frequency amplifier. The output of this automatic gain control circuitry is sent to a wave detector via a zone filter. This wave detector is connected to the inputting point of an AGC circuit by the Feed pack loop. Other outputs of the wave detector are connected to FM detection circuit. This FM detection circuit is a phase Locked loop of a publicly known design, and provides a baseband signal. FM detection circuit has the mixer connected to the output of the 2nd voltage controlled oscillator. The output of this 2nd voltage controlled oscillator is connected to the inputting point of the above-mentioned electronic switch by the part circumference way again. The output of this counting-down circuit is used in order to obtain automatic detailed alignment of receiver 30. Receiver 300A power / output has the power supply circuit designed so that it might be connected to AC track code, and has non-switching AC output. AC relay circuit controlled by a microprocessor provides a change AC output. The receiver has the keyboard circuit connected to keyboard Encocada. A remote keyboard can also be formed in an infrared (IR) transmitter again. The signal from this infrared (rR) transmitter is received in an infrared introduction amplification circuit. The output of this infrared introduction amplification circuit and the output of a keyboard encoder are supplied to the input part of a microcomputer. The microcomputer is connected to the LED7" Isplay circuit. This LED display circuit shows other displays about the request of the permission to the selected operation of a channel designator, time (the clock in a microcomputer was generated), and receiver 30 and desk rambling of a specific program. The output of the microcomputer is connected to the digital-to-analog conversion machine from parallel bus Busy, and this digital-to-analog conversion machine provides a volume control circuit with an input. A mixer receives the audio signal by which the desk ramble was carried out from address possible controller decoder 32 by two separate channels which provide a stereo or a bilingual audio signal. The output of a mixer is transmitted to TV abnormal-conditions machine via a volume control circuit. This TV abnormal-conditions machine receives the video signal by which the desk ramble was carried out from address possible controller decoder 32, and generates that output on RF switch. This RF switch provides required information to a television receiving set, in order to see the program by which the desk ramble was carried out. A receiver and also a detailed explanation, then its microcomputer communicate with address possible controller decoder 32 via the in-series buffer of an interface circuit. By this in-series buffer, a bidirectional data signal can be transmitted between receiver 300 micro computer and the micro controller which controls operation of address possible controller decoder 32. the -- the [A / 2 / figure and ] --B [ 2 ] figure consists of a block diagram of address possible controller decoder 32. The baseband signal from receiver 30 is given to inputting point 40, and is sent to video control circuit 42. In this video control circuit 42, a data stream is used for control of playback of a video signal. Video control circuit 42 has phase Locked loop clock 44 and peak detection circuit 46, and these both are connected to video timing circuit 48. Video Klang Pingu circuit 50 supplies it to a double integral and dumping circuit 52 in response to a clamp gating signal to switch 54 portion of synchronization regenerative circuit 56 at a row from video timing circuit 48. The video signal reproduced and clamped passes switch 54 portion, and is the rear of address possible controller decoder 32! It is sent to video output connector 58.60 /c Existing. Video control circuit 42 investigates a vertical blanking interval about line standard passion, a black level, and a synchronous chip value. From the information carried this information and during the horizontal blanking, the interaction of the video control circuit 42 is carried out to clock 44 and video timing circuit 48, and the clamped video signal which is sent to video switch 54 is played completely. Video control circuit 42 provides the video signal which has enjoyableness with the receiving signal level beyond a Threshold value. The digital bit stream in the horizontal blanking period of a baseband signal is sent to video timing circuit 48. Video timing circuit 48 interfaces with Busy clock 44 and video control circuit 42 in order to guarantee being completely synchronized with the video signal with which address possible controller decoder 32 comes. Video timing circuit 4B performs error amendment about a digital bit stream again using error amendment art. A digital bit stream is sent to the following Busy, data-processing circuit 64, decryption circuit 66, various memories 68.70 and 72, and digital processing circuit 62 containing micro controller 74. Data-processing circuit 64 receives the digital bit stream by which the error (a data stream and the enciphered audio signal are included) was amended. The data stream portion of a digital bit stream is changed into parallel from series, and is sent to micro controller data bus 76. The buffer of the audio portion as which the digital bit stream was enciphered is carried out, and it is sent to audio encryption circuit 66 with an in-series form. The information about the format of video reversal and an audio signal is sent to the control and the state circuit in micro controller 74. The message as which the data stream was enciphered (this message) By using the common audio key information which exists in being deciphered using the feature key of the member unit memorized by memory 70, an audio signal serves as a clear bit deciphered and Ischaryevee(ed). A decryption circuit sends the regular audio bit stream by which the buffer was carried out to data-processing circuit 64, and this data-processing circuit sends audio data, and Companding data and filter data to delta modulator 76 with a clock signal. Delta modulator T6 is used in order to change two digital audio bit streams into the analog voltage similar to the original source of an audio. Two separate audio channels are provided for either a stereo, an audio or a double language program. These two audio channels are connected to receiver 30 via audio switch 7B controlled by audio The emphasis circuit 79, an audio output, and audio auxiliary connectors 80.82 and 84.86. The control logic for this process is acquired from the control and the state circuit in micro controller 74. Demodulator T6 provides the audio signal of the enjoyableness of the receiving signal level beyond a Threshold value using noise reduction art. Control and the state circuit of micro controller 74 control delta demodulator 16 to provide various audio outputs. control and a state circuit -- or [ extracting a video inversion signal, and sending information to a video control circuit, and passing a video signal ] -- or it is made reversed Micro controller 74 is a control device in address possible controller decoder 32. The main function blocks of all are micro controller 740 peripheral equipment containing receiver 30. Micro controller 74 updates all the information continuously, and memorizes member bus code information, a parent control key, a decryption key, and request-to-print-out-files permit data. All the data which is sent to the arbitrary functional blocks in address possible controller decoder 32, or is extracted from this functional block is under control of micro controller 74. The receiver channel alignment instructions inputted by a keystroke and the member can negate each keystroke, can change a channel alignment command, and can update a receiver clock, or can change a display. A cryptographic key is received, and the main functions of micro controller 74 are memorized and are tracing. The peculiar numerals which carried out the form of the common audio key enciphered and individualized are sent to decoder 32 via real time controller 10 and satellite link B. In permanent memory 70 of address possible controller decoder 32, each identification signal which has a form of the feature key of a different member unit from the address numerals of address possible controller decoder 32 and which was stored at the factory is embedded. The feature key and address numerals of this member unit are processed by With rose micro controller 74 so that it may be combined with the enciphered common audio key and a common audio key may be obtained. A common audio key and other program tag information form the decryption key supplied to an audio decryption circuit. Data bus 88 connects address possible controller decoder 32 via buffer circuit 90 to the peripheral equipment of the arbitrary selection which pays by request viewing and listening and can For busy use for report information so that it may indicate below. If the peripheral equipment of this arbitrary selection is not connected and address possible controller decoder 32 does not operate, it is paid by request viewing and listening, and does not permit activity. It pays by request viewing and listening, and programming is placed by the level of the peculiar programming stage of itself, and has all the non-reserving viewing-and-listening programs of further others, i.e., the program of the stage where the member is not registered. Address possible controller decoder 32 memorizes the tag number, days and months, and time of a program when a program is purchased by the member for each [ pays by request viewing and listening and see by a method ] program of every. This information (when real time controller 10 requires data dumping from decoder address possible controller 32), It is sent to the days and months set up as a claim period by either a telephone modem or "smart card" '(smate card) which is essentially a programmable memory at the request viewing-and-listening part data communication processor of a claim center. In the case of a "smart card", it is assumed that this card is sent to a member with the claim valve of the part of the previous month. If this card is received, it will be inserted in an interface box (not shown), and the processing since the last insertion will be moved to this smart card. Next, this smart card is returned to a claim center with a monthly amount paid, and this smart card is processed and updates the charge data of business center computer 14. Preliminary-inspection time is provided by a program generator for every program. This time can be carried out in 15 minutes from 0 minute, and the resolution for each program of every is 15 seconds. The arbitrary members who align with a program at the arbitrary times can give the preliminary-inspection time for a maximum of 15 minutes. if a member shifts alignment from the program, address possible controller decoder 32 will memorize the checked time -- and When alignment is returned while the program has a member, a member's preliminary-inspection time will be shortly restricted to the preliminary-inspection time of the origin which deducted the time which the last preliminary-inspection time took. Address possible controller decoder 32 can observe the simultaneous preliminary-inspection program of two VCl(s) at a certain arbitrary times. Since it pays by all the request viewing and listening and record of a program is the same at all the points, by a tag number, days and months, the time, and a part, address possible controller decoder 32 is paid by all the request viewing and listening, and memorizes use of a program. (when a tag number is changed) Repeating the same event arbitrarily, and viewing and listening to it is also recorded by the same method. Thereby, in reproduction and a claim, the flexibility of But becomes possible to a system operator. Here, it assumes that a member's claim information is updated on a monthly predetermined day. this -- before -- the smart card of a statement -- or telephone contact carries out with a system operator. In order to pay by request viewing and listening in the case of this latter and to operate as a data link in it, a modem and a modem dedicated communication circuit (not shown) are connected to buffer 90. Real time controller 10 is ordered to address possible controller decoder 32 on a predetermined claim day to send a dial pulse to business center computer 14, to pay by request viewing and listening of a former period, and to supply activity to business center computer 14. Business center computer 14 ships a bill to a member periodically. In order to understand the method of processing the control data which address possible controller decoder 32 received, it is required to understand the character of the data signal which occurs at a transmitting end and is transmitted to each address possible controller decoder 32 via a satellite. The format of the baseband signal is shown in Drawing 3. In an NTSC method, an effective video portion occupies 51.4 microseconds of a video line using an NTSC compound format. Two audio channels and control data channels occupy 9 microseconds on the whole during the horizontal blanking. Video frame synchronization-ized information and a zero level standard use line 1~9 of both the fields for a vertical blanking interval, and are transmitted to it. Line 10~21 of a vertical blanking interval is saved for other data services like a teletext. The moment data speed of audio data and control data is 715.9090 bits per for 1 second, and this is twice the chrominance subcarrier frequency. This transmission is in reversal synchronous mode. data is an advance to second base with Non- return Two- 0 (NRZ) method -- it is coded. Control data is sent to address possible controller decoder 32 in the packet-ized form. a packet -- a group -- it becomes a program header by which a receiver 30 hair dress is carried out, and a specific receiver unit in the group from the small packet of many in which an address is possible. If explaining it in full detail, as shown in Drawing 3, the compound television signal includes a plurality of signals of different frequency. Each signal has an effective video portion and a horizontal blanking period (HBr). The bit stream which gather during the continuous horizontal blanking, drives in (run-in) and contains 16 bits of numerals, 44 data bits, 22 error correction bits, and other bits is formed. 8 bits is assigned to program relation, synchronization, and the data stream including control information and in which an address is possible among the 44 above-mentioned data bits. 28 bits are assigned for the enciphered audio information about the two above-mentioned audio channels. 1 bit of key bit information for synchronization of a decryption machine is carried. 1 bit carries the enciphered audio numerals which whether audio broadcast is a stereo or it is a thing of 2 power languages specify. 1 bit of a bit stream is given to the enciphered video inversion signal. The remaining bits of a bit stream are used for other objects. It Atto, and 8 bits of the data stream in which A is possible are collected, and forms the small packet in which the address of a plurality of program headers and one group combined with each of this header is possible. A program header includes the information used by all the address possible controller decoders 32, and it explains the characteristic of the present program currently broadcast on the selected frequency. A different header is transmitted on the frequency assigned to this program for every program. The header contains the group address used in order to choose one of the 65,536 groups of 7 dressing within the limits of a system. No less than each 256 address possible controller decoders 32, as for, an address is carried out by the single group address may exist. Only address possible controller decoder 32 which is a part of that group by which the address was carried out owns the information by which the address was carried out to that group within this data stream. The information included in a data stream can be divided into three specific categories. These categories are program information, a member's specific information, and the whole member's information. Program information is completely contained in the program header portion. A program header is repeatedly broadcast at 3 times or more per for 1 second of speed during the program broadcast. Repetition broadcast of the small packet message in which each address is possible is carried out 8 times. The message contained in this is considered to be transmitted after that eight broadcast. The header packet has two data blocks and the small packet message in which each address is possible contains one data block. A 16-bit error detection word is transmitted after each block. In this way, it is checked for no transmission error by the 16-bit periodic redundant check word to which each data block is called a "checksum" (checksum). 1st error check word, CHECKSUM to which a header packet follows a synchronization word, member group address information, program pertinent information, and this as shown in Drawing 4 It consists of the 1st block containing 1. The 2nd block is paid by request viewing and listening, and contains data and error check word CHECKSUMof The 2nd2. A synchronization word is a word which provides the amount gap of records or gap between continuous data blocks. It drives in with a synchronization word and a word is needed between data blocks. It is generated by real time controller 10, and these consist of a start mode portion (240 sync bits and 8 bits). A member's group address defines some member bases to which the continuing message is sent and in which an address is possible. This group address defines about 65,000 groups which each becomes from 256 members. This information is provided by business center computer 14 as a part of a member's specific information. address information -- an 8 bits system address and a 16-bit group address -- the Wo owner is carried out. Program pertinent information has a 3-bit audio mode portion which defines the kind of audio sent. The audio information is a stereo system when each audio channel contains the half of a program, and it is a monophonic method when both the audio channel includes the same information, Or when carrying the information that each audio channel is separate, with 2 power languages, it is one language and can send to one audio channel in other languages at other audio channels. The following portion is a dynamic video reversal bit used in order to explain video reversal operational mode. This information is sent by studio control computer 12, and can be changed by the operator of a head end. It is whether a video signal is broadcast due to the normal Black vs. White, or it is reversed. The following 3 bits define parents' guidance level. These bits show one of the contents levels of a program of eight pieces about the present program. These levels are compared with the control level of the parents chosen by the user by address possible controller decoder 32. Parents' guidance level is transmitted by studio control computer 12, and can be changed by the operator of a head end. The following 8 bits define encryption 1 number. This encryption 1 number is used in order to choose the piece of a key from the common audio key enciphered so that a decryption key required for decryption of address possible controller decoder 32 of the data stream of an audio could be assembled. A common audio key is transmitted in the form enciphered by the small packet in which an address is possible. 32 Pit of the last of a block of the beginning of the information on a header packet define the permit of the program stage. The permit information on the program stage shows the programming stage where the selected program appears to address possible controller decoder 32. The block of the 2nd of the header packet includes the information about request viewing-and-listening part payment processing data. The 16 bits of the beginning have a program discernment tag which identifies the specific program broadcast. The following 16 bits define the moon when the program identified with a program discernment tag is broadcast, the time, and a part. The following 4 bits define the permissible preliminary-inspection time about the identified program. 4 of the last. A bit defines the price of a program. The information which exists in this block is used by address possible controller decoder 32 in order to explain request viewing-and-listening part payment processing, when a member inputs into a keyboard the required command which requires that a program pays by request viewing and listening, and should be seen by a method. paying a member's specific information included in the small packet in which an address is possible by the information on three different kinds, a fundamental subscriber data, and request viewing and listening -- data -- and -- running (punch through) -- data -- Including and rare To. message form (it can provide by that arbitrary small packet in which an address of one is possible) K this information differs in some -- possible -- it is contained. Generally, as shown in Drawing 5, it is each small packet, It has 160 bits with the field which identifies the address of address possible controller decoder 32, the field which identifies the number of message form, the field which identifies the feature of decryption, and the field for error detection CHECKSUM. When it explains in full detail, the 8 bits of the beginning are given in fact to each member address which is 8 bits of the lowest beam a member's address, and 16 bits of the beam of the topmost peg of a member address are a group address contained in a header packet. 5 bits of message form included in the small packet next to the small packet in which an address is possible in which the address is possible are defined. Seven different message form which attached 1~7 and a number is one of this form like illustration. However, the message form of other kinds can also be used if needed. A message is transmitted in the enciphered form. 3 bits next to the small packet in which each address is possible define the feature number. This feature number is numerals used in order to enable decryption of the message which chooses the piece of a key from the feature key of the member unit memorized by the member unit memory, and is contained in controller decoder 32 in which an address is possible at the small packet in which that address is possible. Furthermore it is related with this feature number, refer to the U.S. patent application pipe No. 710.385 under present pendency by the above-mentioned March 11, 1985 application about another information. The following 128 bit of the small packet in which each address is possible contains the message of the form defined by the indicator of an above-mentioned message form. 16 bits of the last of the small packet in which an address is possible are mistaken, and contains check word CHECKSUM. the -- as shown inA [ 6 ] figure, message form 1 contains three portions and the all contain the subscriber data. 32 bits of message form 1 define a permit bit map. This bit map expresses the permit of the request-to-print-out-files stage of address possible controller decoder 32 with 32 bits. This field shows which programming stage was paid the price by the request to print out files to address possible controller decoder 32. It generates by business center computer and this information is memorized by the disk memory of a real time controller. 80 bits of the 10th kind of message of common audio keys required for decryption of the enciphered audio signal are defined. This common audio key exists in the form enciphered since it existed as an enciphered message. Since each message is enciphered by different Way for every receiver, encryption of a common audio key is individualized for every member unit. By use of the member unit feature key memorized by the memory of each member unit at the factory, each member unit deciphers the message, in order to obtain a common audio key. Refer to the U.S. patent application 665..No. 114 under present pendency for the details about a common audio key and its use by the above-mentioned October 26, 1984 application. 6 bits of the last of message form 1 are given to the field which defines the "home" channel with which a terminal receiver is aligned when address possible controller decoder 32 is in off-mode. It generates by business center computer, and the number of this home channel is memorized by the disk memory of real time controller 10. the -- as shown inB [ 6 ] figure, message form 2 includes the member's request viewing-and-listening part payment information. The first 32 bits of message form 2 define the disturbance bit map which restricts access to the specific programming stage completely. It generates by business center computer, and this information is carried out on a member's specific information, and is memorized by the disk memory of real time controller 10. Furthermore it is related with the method of using a disturbance bit map, refer to the U.S. patent application No. 710,466 under present pendency for detailed information by application on March 11, 1985. Generally, each address possible controller decoder 32 is in a permit bit map memory, Although it can usually use for request viewing-and-listening part payment processing, it has a disturbance bit map memory which prevents the display of the specific programming stage specified that it is unsuitable Own by the member for seeing at its home. For example, one of the programming stages may contain the sexual movie [ Exposition ] which does not want a member to make its child see. Although the child may know the bus code of the member who usually starts request viewing-and-listening part payment processing, when specified as that by which the programming stage should be blocked, the request viewing-and-listening part payment processing cannot be started. Usually, when a request to print out files is begun, a member tells which programming stage should be blocked by the system operator. real time controller 10 -- a system operator -- the next -- 1 -- a member's address possible controller decoder 32 is told by providing a required disturbance bit map about the programming stage which should be blocked. A disturbance bit map is [ a system operator only being able to change, and only being changed when the notice from a member like the power of attorney of a form who should usually change a disturbance pattern is obtained, and ]. A disturbance bit map is changeable with real time controller 10 in a system operator's bottom KS of control at any time. 28 bits next to [ of message form ] 2 are used for address possible controller decoder 32 with telephonic-communications capability. These bits define the day of a month when giving a command to autodial accessories so that the member unit by which the address was carried out may call a business center computer, the time, and a part. It generates by business center computer and this information is memorized by the disk memory of real time controller 10 as a member's specific information. 16 bits next to message form 2- define the credit side / debit value about request viewing-and-listening part payment processing. This number defines the amount of money which a televiewer has to pay to the right to see the program related to request viewing-and-listening part payment processing. The treating number defined by 8 bits next to this message is one of the treating numbers of 256 pieces, and is given for every new request viewing-and-listening part payment processing. Thereby, when broadcasting the same program in two places or more places, the possibility of the double credit side or the debtor performed by address possible controller decoder 32 is removed. This information occurs by business center computer. The following 16 bits define the bus code of a telephone, and is used for address possible controller decoder 32 with telephonic-communications capability. This word is used in order to check the telephone answer from a business center computer after the sequence of autodial is completed. It is generated with real time controller 10, and this field cannot be accessed for some operators of a head end. 16 bits next to this message contain the watchword of a credit card. This field is memorized and used by address possible controller decoder 32 provided with the option of an electronic credit card. The above-mentioned watchword is used in order to check insertion of the right electronic credit card (smart card) every, whenever a credit card is inserted in a member unit. It pays by request viewing and listening, and Transfer fly of data is not permitted if this check process is not completed successfully. It is generated with real time controller 10, and this field cannot be accessed for some operators of a head end. 16 bits of the last of message form 2 are given to an overflow calling-in level. Since this data cannot be operated by a member's telephone wire, Or when the telephone call at the time of the calling-in time before specified for one for being used for the specified calling-in time of reasons is not completed, address possible controller decoder 32 is told about the time of calling a business center computer. message form 3 -- the -- it is shown inC [ 6 ] figure. This message form is paid by additional request viewing and listening, and contains telephone data. The 64 bits of the beginning define a calling-in telephone number. The following 64 bits define an alternative calling-in telephone number, when closed at the time of calling in as which the appointed telephone number was specified before. the --D [ 6 ] figure shows message form 4. Message metal carving 4 contains the data sent by the small packet which has an overall address including the suitable possible control information for overall data, i.e., all the address possible controller decoders 32 in a group with the defined header packet, and in which an address is possible. It A message and form 4 contains 128 bits which appoints the rediscount reliance table of eight channels. Address possible controller decoder 32 uses the information included in this display, in order to change the Canyell alignment characteristic of receiver 30. If a user inputs a channel designator into receiving PIt10, address possible controller decoder 32 scans the channel rediscount reliance table. Coincidence of the inputted channel designator and input record of the table will send the output record to receiver 30 of the place. This feature means making this easy clearly, when the dynamic rediscount reliance of transponder frequency is required of a user. When the specific transponder of satellite B is out of order for example, this feature is used and enables it for another transponder to receive a program on another frequency. It generates only by the operator of a head end, and this information is memorized in one table of real time controller 10. This data is located in the message by which is common to all the members and an address is carried out as mentioned above on the whole. the --E [ 6 ] figure draws message form 5. Message form 5 has 128 bits and functions as message form 4 similarly about eight additional RF channels. this information occurs by the operator of a head end again -- and message form 4 -- and it is used only when eight or more RF channels require rediscount reliance. On the whole, the address of this message is carried out again. As shown in the 6th F figure, Piercing contains both data and overall data in message form 6. Punch through arises immediately in a data stream by use of this message form, and a new packet header is compulsorily used only about this one message. That as which, as for this Piercing, data was chosen of the peripheral equipment of address possible controller decoder 32 (one of them is a receiver, and it processes the data of a data stream, and is /) Or - by which a route arrangement is carried out immediately without receiving displaying and the data of a data stream processing via address possible controller decoder 32 is meant. The first 32 bits of message form 6 provide the information for controlling 4 bits of receiver 30, and the display of seven segments directly. Enabling of the data of this field will display it on the display of a receiver. Each bit is moved to one LED segment. Thereby, all the displays can display the same time, for example. 16 bits next to message form 6 are related with a state of each address possible controller decoder 32. In particular, it is related with the control and reset function. Each bit of this field is used in order to reset the specific function of address possible controller decoder 32. For example, Tampa (tamper)- of control decoder 32 in which the address of 1 bit is possible The flag of address possible controller decoder 32 like a flag is resettable. Another bit can be used in order to reset the bus code of 4 figures which the user used for parent control and request viewing-and-listening part payment processing chose. 16 bits of the 60th message form are given to the information on audio Threshold and data Threshold. The byte of audio Threshold is used in order to program cutting Threshold for an audio data stream. The byte of data Threshold is used in order to program cutting Threshold for a control data stream. Programming next to message form 6 with specific 30 bits and usual have the deletion and the relation on graphics, such as a sporting event. This programming imposes the control which cannot be received in the geography zone where that sporting event is performed so that the number of the visitors to that sporting event may not be damaged, and is often broadcast. Detailed opinion and Ming of the way this deletion method operates by the present invention are indicated to U.S. Serial Number 672,925 under present pendency by application on November 19, 1984. Generally, each address possible controller decoder 32 other than a permit bit map memory and a disturbance bit map memory has deletion mark Lame memory and a geography zone numerals memory. The address of the message form 6 is carried out to all the address possible controller decoders 32 in a fixed geography zone, and the specific ship code memorized by the geography numerals memory is supplied to each address possible controller decoder 32 by which the address was carried out. These ship codes differ for every geography zone. next, each decoder with the specific ship code address possible controller decoder (plurality) 32 was remembered to be by the geography numerals memory -- the deletion numerals memory Busy -- specific deletion numerals should be inputted -- on the whole, an address is carried out by the command to carry out. The deletion numerals are transmitted like a ship code via message form 6. Each program is broadcast with the program stage permit information on a related header. If a program is received, each receiving unit compares the permit matter and the deletion numerals of a deletion sign bit memory of the program stage accompanied by the program. When the information on the transmitted stage is in agreement with the deletion numerals of the deletion sign bit memory, the receiver cannot do display Russ To of the program. Since a ship code and deletion numerals are completely stored in address possible controller decoder 32 before broadcast of the program which should be deleted in a specific geography zone, all the address possible controller decoders 32 in the geography zone which should be deleted delete the program simultaneously. This is a big advantage on operation. That is, the address of each address possible controller decoder 32 in the geography zone will need to be separately carried out to deletion of the program in a specific geography zone, and the operation may usually take the time beyond 10 minutes or it. This cannot be carried out before broadcast of the program which should be deleted since a pre- program is not usually deleted. On the other hand, when carried out after the start of the program from which it should be deleted, the person with a televiewer can receive at least one copy of a deletion program, therefore in order that a televiewer may look at a part of the program before the program is deleted, irritation arises in the televiewer side. 32 bits of message form 6 have a trap message bit map for in turf Esing of peripheral equipment. Each bit of this field is used in order to carry out the trap of the related message form. Although Acceptance takes these messages and controller decoder 32 in which an address is possible outputs them to peripheral equipment for processing further, operation beyond it is not carried out. The trap of the message form 6 is never carried out, carrying out a deer. The 6thG figure is drawing message form 7. Message 7 has two features which consist of 64 bits of peripheral equipment. These features define the output which carries out the route arrangement of the specific message by which the trap was carried out, and sends it so that it may be connected to specific peripheral equipment. For example, the teletext display unit for displaying the processing information on a stock market is also connectable with the specific output of address possible controller decoder 32. The message which should be displayed by this peripheral equipment is sent by message form 6, and a trap is carried out to the memory of controller decoder 32 in which an address is possible. Next, message form 7 is provided in order to order address possible controller decoder 32 to carry out a route arrangement and to send to the display peripheral equipment of the message t teletext by which the trap was carried out in front. Since the header portion of the data stream includes program pertinent information like the request viewing-and-listening part payment information about permit specification of a parent guidance level and the program stage and a specific channel, or the stage among other Condolence news, A different header for every programming channel or stage is broadcast. On the other hand, the bucket (plurality) in which an address is possible includes usable information respectively only with program permit information, the enciphered common audio key, and a specific receiving unit like program disturbance information by which the address was carried out. The packet by which an address is carried out is simultaneously broadcast in all the channels or stages. As shown in Drawing 7, a specific programming channel or stage answers operation by the member of the keyboard relevant to a receiver, and is chosen by the tuning section of the receiver. A keyboard signal is processed and is received as an input to the microcomputer which controls the tuning section of a receiver. Like, the microcomputer of a receiver is divided to Above and micro controller 74 and the information on address possible controller decoder 32 are exchanged for it about the selected programming channel or the stage, and the frequency with which the tuning section is aligning. An alignment signal is transmitted to the video control circuit of address possible controller decoder 32 from a tuning section. The digital ingredient of an alignment signal is separated from a video ingredient. Video, audio control information, and the enciphered audio signal are transmitted to a suitable circuit for processing. Next, it is investigated in order to trace a header and to obtain a group address. A group address is compared with the group address memorized by the memory of address possible controller decoder 32. When these group addresses coincide with each other with each other, this shows that the information relevant to the receiving unit with specific at least one of the packet in which the address of a data stream is possible may be included. (It is applicable to all the receiving unit) The synchronization information in a header, program pertinent information, and request viewing-and-listening part payment information are caught, and are memorized by the memory under control of the microprocessor of address possible controller decoder 32. Synchronization and video control information are used in order to play and process a video signal. (When this video signal is cleared for a display, I/c is returned to a receiver). When a receiving unit does not exist in the group by which the address was carried out, a sequence will finish, and a circuit will wait for the following header. When a receiving unit exists in the group by which the address was carried out, the packet in which each address is possible is supervised one by one. (It is applicable to all the receiving units in a group) The information in arbitrary packets with a whole address is caught, and it is memorized in order to use it in the future. If a packet is traced in the address of a receiving unit, the message form included in it will be notified, and the decryption information in the packet will be used for decryption of the message with the key information on the memory of the address possible controller decoder 32. Next, since it is used by micro controller T4, the information on a message is memorized. The method of using message information and a case are dependent on the character of the information. For example, the message (whether [ that the selected channel or stage is a thing of request-to-print-out-files within the limits ]), And a suitable memory is given when it is the command which sets up the permit bit map or disturbance bit map used in order to determine whether the display is blocked for a certain reason. If chosen for viewing and listening of a specific channel or stage, a micro controller will investigate these memories, that how or this material cannot be displayed under any situations although it can see, without that selected channel or stage further operating it or request viewing-and-listening part payment processing is required whether -- about -- it determines. On the other hand, when a message calls in and the command about a claim like time is included, this information is memorized until it is needed. At the suitable time, in order that one micro controller 74 may operate an audio dial and a modem circuit and may make a system operator report information, this information is used for it. Therefore, the header includes a peculiar combination of data, i.e., synchronization information, group address information, and program pertinent information. The memory of Add- possible controller decoder 32 memorizes, and it is before obtained from the packet in which an address is possible, Or when used with the information memorized by the memory at the factory in the case of a member's feature key, the information on the above-mentioned header controls reproduction of a program, a display, claim procedure, and other various control facilities. This data format and operating system constitute the easy method of distributing a program and control information by a safe method. Now, it should be understood that the present invention is a thing about the signal transmission method with which the address of each member receiving unit can be carried out, and it can be controlled by a real time method. The address of each member receiving unit is carried out, and it is controlled by a real time method, It is a data stream inserted in the horizontal blanking portion of the compound television signal distributed, Usage of the data stream containing the portion including the information for control of the enciphered audio portion, a header portion including information applicable to control of all the receivers, and a specific member unit, and in which a plurality of addresses are possible -- it is possible. Each of the portion in which the address is possible includes the information which enables the member unit by which the address was carried out to the message to decipher the message. A system operator can change a message in real time with an in-line controller so that various functions of a member unit by which the address was carried out may be controlled directly. Although indicated here for illustration of only one suitable example of the present invention, it is clear that many modification and change can accomplish to this example. Therefore, a claim tries to include all these modification included in the range of the present invention, and change.
