The invention will now be described with reference to <figref idrefs="f0001">figures 1</figref> and <figref idrefs="f0002">2</figref>.

As shown in <figref idrefs="f0001">figure 1</figref>The invention proposes to use at least one network (5) portable radio and integrate terminal equipment (100) programming a recording device (1) such as a VCR or DVD media recording device (Digital Versatile Disc) or other media device capable of recording video information (14), so as to perform a remote programming of one or several programs aired on broadcasters programs of broadcast channels, like for example the TV, without prior knowledge of programs or broadcasting channels.

In one embodiment of the invention, the SMS-CB technology is deployed in the network (5) of the mobile radio over the entire radio subsystem "BSS" (Base Station Subsystem) of the telecommunication operator and CBCH of channels (Cell broadcast channel) are defined to allow the issue (500) by emitting devices (TRX1, TRX2) base stations (BTS) of data to recording devices (1) equipped with a terminal equipment ( 100) programming. Each base station (BTS) is then the interface between the base station controller (BSC) managing the radio resource and the terminal equipment (100). An antenna (11) transmitting / receiving radio and reception and reading means (10) of these data are incorporated in said terminal equipment (100). Data transmission is possible via the antenna (11), data transmitting means may be integrated in the terminal equipment (100). It is understood that the existing infrastructure for the network (5) mobile telephone can allow the implementation of the SMS-CB technology to terminal equipment (100) programming considered transmitters / receivers of mobile phones. The antenna transmit / receive is for example compatible with a mobile radio network GSM, GPRS, UMTS, etc ... or the like and the reception and reading means (10) have means of access to downlink channel diffusion CBCH said network to allow the reading of at least one SMS-CB type text message.

The data transmitted by the network (5), called in the following information data (D) are representative of a program elements programming schedule of a plurality of broadcasters of programs and identification information of these program elements. In the preferred embodiment of the invention, they are transmitted in SMS-CB type text messages, so that several recording devices (1) located in the same area covered by one or more radio cells (50) of the network (5) can receive the same data provided in the SMS-CB text messages on CBCH defined for this area. The<figref idrefs="f0002">2</figref> and represents one radio cell (50) in which a radio transmission (500) is performed on the CBCH channel to disseminate intelligence information on program elements that can be read by the terminal equipment (100) recording devices (1) located in the cell (50).

The original content (4) Service may be provided by the Boards of program broadcasters, for example television, to a server (3) having means for connection to at least one mobile radio network. This original content (4) includes programming schedule information of program elements and identification of these program elements information. The original content (4) is for instance coded by a reference transformation system for forming information data (D) arranged in a plurality of concatenation sequences (6) each refer to a particular program element. The server (3) comprises storage means (30) for storing a database formed with said information data (D) encoded thereby. The server (3) connected to at least one mobile radiotelephony network (5) diffuses into at least one text message data from said database on one or more network broadcast channels (5). In the preferred embodiment of the invention, the radio network subsystem (5) is connected to the server (3) and at least a broadcast downlink channel CBCH of said network to allow transmission (500) of data coded information (D) from said database into one or more SMS-CB-type text messages in a specific area covered by one or more radio cells (50) of the network.

The reception and reading means (10) of the terminal equipment (100) used in the programming of recordings programming system according to the invention are used to read text messages transmitted on the channel broadcasting the coded information data (D ) of the server (3). The recording device (1) comprises an input interface (13) connected to the terminal equipment (100) programming to allow the user to enter a type of program to record. The terminal equipment (100) for programming may comprise coding means (not shown) for encoding the program type with a determined format similar to the format used by the reference transformation system for encoding some of the information about an element program.

The invention will now be described with reference to <figref idrefs="f0001">figures 1</figref>, <figref idrefs="f0002">3 and 4</figref>.

According to the invention, the user can achieve a thematic program of issue (s) with the input interface, the coding means encoding the desired program type in a registration code (2) having said determined format. This recording code (2) is stored in storage means (M) of the terminal equipment (100) programming. These storage means (M) may consist of a type of RAM (Random Access Memory) or type flash or other type of fast memory access. In the example of<figref idrefs="f0002">3</figref>, The recording code (2) comprises a sequence concatenating the following set of data:<ul><li>three-character string in a first field for representing the category (201) of the program element;</li><li>two-character string in a second field to represent the type (202) of the program element;</li><li>two-character string in a third field to represent the sub-genre (203) of the program element; </li><li>three-character string in a fourth and last field to represent the broadcast channel of a program broadcaster (204) of the program element.</li></ul>

In an alternative embodiment, the registration code (2) may not include information on the broadcast channel. In another embodiment, two characters are enough to represent the broadcast channel of a program broadcaster (204). Naturally, the number of characters contemplated for each of the fields of the sequence may be higher, for example greater than three characters. It is understood that the said specific format for the recording code (2) comprises a sequence including concatenating data representative of class, gender and possibly sub-genre of a program element, so it is possible a user to establish a program with the input interface (13) ignoring the precise timeframe of the program element. The broadcast channel can be ignored or not by the user. In one embodiment of the invention, a non-field entered for the broadcast channel may not prevent the consideration of thematic programming by the user. Data for specifying a broadcast channel of a program broadcaster may however be included in the sequence forming the recording code (2). Programming and enabled by the invention can be used to save a program element recognized by its category, genre and subgenre, such as a sports category in issue, of which gender is football and is a subgenre national championship game.

As shown in the embodiment of the <figref idrefs="f0002">4</figref>, The information data (D) from the server's database (3) may be in the form of concatenation sequences (6) relating to program elements, each sequence being divided into two parts (61, 62 ). In the non-limiting example of the<figref idrefs="f0002">4</figref>, The first portion (61) is encoded by the reference transformation system with a format that can be found for the establishment of the recording code (2), so that this first part (61) is at any point comparable with the registration code (2). The first part thus comprises a field with at least three characters to indicate a category (611), a field with at least two characters to specify a genre (612), a field with at least two positions to denote a subgenus (613 ) and a field with at least two or three characters to specify a broadcast channel (614). The second complementary part (62) includes a string that identifies the timeframe of the program element, that is to say, the beginning and the end of this program element. The second part (62) can be formed from 14 characters indicating eg date with 6 characters - 2 for the year, 2 for the month, 2 for the day - and schedule starts and ends with 8 characters - 4 characters for the hour and minute of first 4 characters for the hour and minute late. Each of the program elements may be defined by a concatenation sequence (6) such as that illustrated in<figref idrefs="f0002">4</figref> or an equivalent sequence containing a representation similar information encoded by the reference transformation system. In one embodiment of the invention, the storage means (M) of the terminal equipment (100) can be used to store all the SMS-CB message type.

As shown in <figref idrefs="f0001">figure 1</figref>The terminal equipment (100) programming has processing means (12), such as a central processing unit, comprising a discrimination module for detecting at least one program element to be recorded by comparing at least the first portion (61) of each of the concatenation sequences (6) with the recording code (2). automatic parameterization means using the first part (61) discriminated and / or its second complementary part (62) are also provided in the processing means (12) to set the recording device (1) the registration of the element detected program. These automatic setting means enable the program in the recording device (1) the beginning and end of the recording so that the broadcast channel of the program element detected by the discrimination module.

In one embodiment of the invention, the discrimination module comprises means for comparing data respectively representing the broadcast channel, a category, and at least one classification per genre of the program element. Storage means (M) are arranged for storing in a register the concatenation sequence (6) comprising the encoded portion (61) with said predetermined format in which the data compared by the comparison means are identical to those of the recording code (2), the automatic parameterisation means being connected to storage means (M) to use the sequence of recording data (6) stored in said register.

The terminal equipment (100) programmed with an identity module (SIM) consists of a SIM or USIM type of smart card for network second or third generation or an equivalent card with a memory configurable data of authorization of access to a network broadcast channel (5). This identity module (SIM), incorporated in said receiving and reading means (10) may allow you to lock or reading data published on the CBCH or analogue channel. Access to the service provider of intelligence data (D) established by the network (5) via the CBCH channel can be blocked by sending a message to the identity module (SIM), for example in the case of an unsubscribe the user to the service. In one embodiment of the invention, an access step of blocking the network broadcast channel (5) mobile telephone is carried out on the one hand by identification in the terminal equipment (100) programming of the modulus identity (SIM), and on the other hand by modification of said access authorization data.

The invention will now be described in connection with the <figref idrefs="f0001">figures 1</figref> and <figref idrefs="f0003">5</figref>.

As shown in <figref idrefs="f0003">5</figref>The process according to the invention requires a phase (40) for transforming the initial content (4) of the service, the identification information and programming schedule for program elements being encoded concatenation sequences (6) and a step (41) for storing the sequences (6) in a database, in memory means (30) of the server (3).

In the preferred embodiment of the invention, the user intervenes only once in the process, in a first step (20) comprising programming the user input of at least one type program to record using the input interface (13) of the recording device (1). It follows a storage (21) of the recording code (2) representative of the recording instructions in the storage means (M) of the terminal equipment (100) programming.

The recordings programming process according to the invention can then continue after a step (22) is received by the receiving means and reading (10) of the terminal equipment (100) encoded data information (D) transmitted on at least one network of the broadcast channel (5) in text messages. This step (22) of reception provides the concatenation sequences (6) each defining one of the program elements by means of the first coded part (61) with the size of the recording code (2) and the second complementary part (62). These sequences (6) can be stored in the storage means (M) of the terminal equipment (100). Therefore, a step (23) of detecting at least one desired program element is carried out by the discrimination of the plurality of first coded parts (61) of at least one first part similar to the recording code (2) . This step (23) and enables detection to identify the sequence (6) comprising the encoded portion (61) discriminated and trigger a second step (24) of programming automatically performed by the terminal equipment (100). The first discriminated part and / or the second complementary part is then used to set the recording device (1) recording the program element detected. If none of the concatenation sequences (6) comprises a first réceptionnées not encoded portion similar to the recording code (2), the detection step (23) results in the conservation of the registration code in pending new stage (22) for receiving information encoded data (D) transmitted from the server (3). Alternatively, if no program element is detected at the end of step (23) of detection, the recording code (2) can be immediately erased from the storage means (M) or deleted to the after another detection step carried out after a new reception information of coded data (D).

Step (23) detection is used to trigger the programming of one or more detected program elements. The set of sequences (6) of the information data (D) can be deleted from the storage means (M) when step (23) of detection was carried out for all the concatenation sequences (6). Alternatively, the sequences (6) non-discriminated can be removed one by one during step (23) of detection.

In one embodiment of the invention, the registration code (2) can include details of the start and end times of the program element. The first step (20) includes programming and entering a recording time range, the input interface (13) being arranged to allow the user to set the minute a beginning and an end for type of program. Step (23) for detecting then comprises the discrimination of the assembly formed by the first and second portions (61, 62) of the concatenation sequence (6). In an alternative embodiment, the discrimination is performed by eliminating the program material disseminated outside of the timeframe set by the user.

The first step (20) Programming may also include a prioritization of at least one characteristic relating to the type of program to record. A module gest ion recording priority is for example built-in processing means (12). Such management module also prevents records from rehearsals for program elements broadcast several times at different times. In other words the recording priorities management module avoids the conflict between coded portions (61) redundant, for example by removing the concatenation sequences (6) with identical data - except the time slot data - in a concatenation sequence already detected in step (23) of detection.

The process of diffusion of information data (D) may comprise a sequence of encrypting step (6) transmitted over the broadcast channel CBCH, and one of these sequences decrypting step (6) by the reception and reading means (10 ) of the terminal equipment (100). The server (3) comprises for example data encryption means to emit the concatenation sequences so as not "readable" on the network (5) mobile telephone. In one embodiment of the invention, the terminal equipment (100) for programming comprises means for decrypting these data (D) sent by the server (3) and encryption for sending records codes ( 2) to means for storing and indexing the server. It comprises decryption means for the reception of the codes (2).

One advantage of the invention is to provide an application between a network and a recording device, allowing the user to set his simple way device, with a registration code, without guidance specific time cognition emissions program or broadcast channels, he wants to save. These are the data included in the transmitted messages that provide the parameters required for the automatic programming of the recording device.

Another advantage of the invention lies in the use of cell broadcast technology "Cell Broadcast", more efficient than conventional broadcast SMS text messages if there are several thousands of recording devices to target. In addition, the diffusion may be performed in real time.

It is also important to note that in the preferred embodiment of the invention, activation of the SMS-CB receiving channel on the SIM card constituting the identity module (SIM) can be performed manually on a map existing SIM (the existing SIM card can then be inserted into the recorder receiving apparatus). The operator can manage the activation fee or disabling a CB channel on SIM card in a mobile station, the customer has access through its mobile station entry interface for activation or disabling channels (principle of "opt-in"). The technique used in the preferred embodiment of the invention is the activation and remote deactivation ( "Over The Air") on the SIM card of the SMS-CB channel reception, depending on the validity of the subscription of the user.

In addition and advantageously, according to the present invention it is possible to retrieve the user programming codes on the programming interface of the recorder to an operator database, via an SMS-MO ( "Mobile Originated "). In other words, the recording codes (2) programs stored in the terminal equipment (100) programming are sent over an SMS channel of the network (5) mobile telephone, to use a knowledge database statistical. The server (3) includes, for example storage and indexing means records codes (2) programs and issued by the terminal equipment (100) programming. An advantage of such operator base is to promote effective knowledge or statistics on recorded programs and programs, such as the knowledge of a broadcast recording rate.

In terms of measurement "médiamétrique" This acquisition is in fact genuinely a big interest. For example, advertisers could see the low interest in communicating an event (date of validity of the very limited advertising) on ​​late slots, nocturnal emissions being the most recorded and when the client looks at them, for example in the following week, then the often outdated advertising is no longer of great interest. Conversely, for a hearing "médiamétrique" very low, a high rate of registration may be an interesting factor for the producer of the program that will be able to renegotiate with its diffuser programming time of the broadcast or review the content to fit the audience in the broadcast time period of the program.

It should be obvious to those skilled in the art that the present invention allows embodiments in many other specific forms without departing from the scope of the invention as claimed. Therefore, the present embodiments must be considered illustrative, but can be modified within the field defined by the scope of the appended claims and the invention should not be limited to the details given above.
