[0021] The analog video signal and audio signal (hereinafter, if necessary, the video signal and audio signal are collectively referred to as a video / audio signal) are generated by the TV signal generation circuit 21 and output to the multiplexer 24. Has been done.
Further, the text data signal related to the TV (television) program is generated by the text data signal generation circuit 22 and output to the multiplexer 24.
Further, the hypertext data signal corresponding to the text data signal related to the TV program is generated by the hypertext data signal generation circuit 23 and output to the multiplexer 24.
[0024] The multiplexer 24 inserts a text data signal and a corresponding hypertext data signal on a predetermined horizontal scanning line of a VBI (Vertical Blanking Interval) of an analog video signal, and one TV. Multiplex to broadcast signal. For example, in teletext broadcasting (closed captioning) in which characters corresponding to audio signals can be displayed on the screen as subtitles, the text data signal is multiplexed on the 21st scanning line of the vertical blanking interval of the video signal. However, in the same manner as this, the hypertext data is multiplexed on the scanning line of the other vertical blanking interval of the video signal. The multiplexed TV broadcast signal is output as a radio wave from the antenna 2 via the transmission circuit 25.
[0025] In this way, the text data signal, the hypertext data signal, and the TV video / audio signal are multiplexed into one TV broadcast signal and output from the antenna 2.
[0026] FIG. 2 is a block diagram showing a configuration of an embodiment of the television receiver of the present invention. The TV broadcast signal including the TV video / audio signal, the text data signal, and the hyper text data signal is received by the antenna 11 and input to the TV receiver 17.
[0027] The TV broadcast receiving circuit 31 of the TV receiver 17 selects a designated TV broadcast signal from the control microcomputer 34, extracts and demodulates the designated one from a plurality of TV broadcast signals, and obtains the same. The video / audio signal is output to the video / audio processing circuit 33. Therefore, the TV program specified by the user is selected and extracted from the TV broadcast signals by the TV broadcast receiving circuit 31.
[0028] The data broadcast receiving circuit 32 selects and demodulates a text data signal (closed caption signal) included in the TV broadcast signal designated by the control microcomputer 34, and outputs the text data signal (closed caption signal) to the video / audio processing circuit 33. ing. Therefore, the teletext (text data signal) specified by the user is selected and extracted from the TV broadcast signals by the data broadcast receiving circuit 32.
[0029] On the other hand, the control data signal composed of the text data signal (as an EPG) for program guidance control and the hypertext data signal corresponding to the text data signal is multiplexed on a predetermined horizontal scanning line of the video signal. It is difficult to send many control data signals at one time because they are transmitted. Therefore, these signals are transmitted from the TV broadcasting station at a timing different from that of the TV video / audio signal, extracted and demodulated by the data broadcasting receiving circuit 32 of the TV receiver 17, and passed through the control microcomputer 34 to the HDD ( It is stored in the hard disk drive) 35, and is read from the HDD 35 and processed as needed. For example, even if a TV broadcasting station outputs a TV broadcasting signal in which these signals are multiplexed at night when the TV program ends, and the TV receiver 17 stores these signals in the HDD 35 at night. Good.
The video / audio processing circuit 33 processes the video signal input from the TV broadcast receiving circuit 31 and generates a video signal to be supplied to the CRT 36. Further, the video / audio processing circuit 33 superimposes a text data signal (closed caption signal) output from the data broadcast reception circuit 33 or an image data signal output from the control microcomputer 34 on the TV video signal, and video The signal is output to the CRT36.
Further, the video / audio processing circuit 33 is adapted to output to the speaker 37 after performing processing such as amplification on the audio signal input from the TV broadcast receiving circuit 31.
The infrared TV operation signal from the remote commander 13 is processed by the light receiving unit 13a and the control microcomputer 34, and as a result, a designated TV video / audio signal selection and demodulation command is output to the TV broadcast reception circuit 31. The text data signal (closed caption signal) is selected and a demodulation command is output to the data broadcast receiving circuit 32.
Further, an instruction signal (a signal output by the operation of the program guide key 41 of FIG. 3, which will be described later using FIG. 3) for instructing the display of the program guide from the remote commander 13 is input to the control microcomputer 34. Then, the control microcomputer 34 generates an image data (data for displaying the homepage) signal corresponding to the control data signal read from the HDD 35, and outputs the signal to the video / audio processing circuit 33.
[0034] Further, when an instruction signal instructing the process for program guidance from the remote modem 13 is input to the control microcomputer 34, the control microcomputer 34 gives an instruction using the control data signal read from the HDD 35. A control signal for executing a process corresponding to the signal is transmitted to the VCR (VIDEO CASSETTE RECORDER) 14 via the infrared light emitting unit 14a, or is transmitted to the modem 15 via the connector 15a. Further, various processing is performed by generating an image data signal and outputting it to the video / audio processing circuit 33.
When the user turns off the power switch (not shown) of the TV receiver 17, the TV channel being output at that time is stored in the non-volatile memory (not shown) in the control microcomputer 34. The next time the user turns on the power switch of the TV receiver 17, the video / audio output processing of the TV channel recorded in the control microcomputer 34 is performed.
[0036] FIG. 3 is a diagram showing an example of an operation unit of the remote commander 13.
[0037] This operation unit includes a program guide key 41, up / down / left / right keys 42 to 45, a confirmation key 46, a numeric keypad 47, and a teletext key 48.
[0038] The TV receiver 17 shown in FIG. 2 is adapted to operate in a TV operation mode in which control is performed by TV operation as in the conventional case and a program guidance mode in which control is performed using hypertext data signals.
[0039] The program guidance key 41 is a key for switching between the program guidance mode and the TV operation mode, and each time the user presses the program guidance key 41 once, the program guidance mode and the TV operation mode are switched. ing.
[0040] The selection of the TV program and the selection of the teletext in the TV operation mode are performed by the up / down keys 42, 43, the numeric keypad 47, and the teletext key 48. For example, if the user presses the up key 42 (or down key 43) once, the TV program of the next (or previous) channel is selected, or if any of the numbers indicated by the ten keys 47 is pressed, The TV program of the channel corresponding to the number is selected, and when the teletext key 48 is pressed once, the text data signal (closed caption signal) multiplexed with the video / audio signal of the TV program of the selected channel is selected. ) Is selected and the text characters are displayed.
On the other hand, in the control mode, the user controls the cursor by operating the up / down / left / right keys 42 to 45 from the selection screen using the GUI for selecting the control of the TV receiver 17. After moving to the area on the screen shown and selecting the control content, the control content is determined by operating the confirmation key 46.
[0042] Next, a specific operation using this operation unit, a processing operation corresponding to the operation, and a display screen will be described with reference to the drawings after FIG.
[0043] FIG. 4 is a flowchart illustrating a processing operation of the TV receiver 17.
[0044] First, the operation in the TV operation mode will be described.
[0045] When the user presses the power switch (not shown) to put the TV receiver 17 into the operating state, the operating mode of the TV receiver 17 is initially set to the TV operation mode in step S11 of FIG. To. Further, in this state, the state when the user last turned off the power switch (not shown) of the TV receiver 17 is held in the memory in the control microcomputer 34, and the channel is selected at that time. The video and audio of the TV program of the channel that was set is output as the default.
[0046] In the following step S12, the process of waiting for reception of the input signal from the user is performed, and the video / audio of the TV program of the channel initialized in step S11 is continuously output until the instruction signal from the user is input. ..
From this state, when the user presses the upper key 42 of the operation unit shown in FIG. 3 once for the purpose of selecting a certain TV program, an instruction signal is transmitted from the remote commander 13 to the TV receiver 17. Is output.
[0048] When the TV receiver 17 inputs this instruction signal, the process of waiting for reception of the input signal in step S12 is canceled, and in step S13, the control microcomputer 34 of the TV receiver 17 receives the input signal of the program of FIG. It is determined whether or not the signal is from the guide key 41. In this case, since the input signal is a TV operation signal instructing the selection of the TV program, it is determined that the input signal is not the instruction signal by the program guide key 41, and the process of step S19 is performed.
[0049] In step S19, it is determined whether or not the program guidance mode is set. In this case, since the TV receiver 17 is operating in the TV operation mode, it is determined that the program guidance mode is not set, and the processing of the subsequent step S20 is executed.
[0050] In step S20, the control microcomputer 34 selects the TV program of the channel specified by the user (in this case, the TV program of the next channel) to the TV broadcast receiving circuit 31 according to the instruction signal from the user. Outputs the instruction signal to instruct. In response to this command, the TV broadcast receiving circuit 31 extracts and demodulates the designated TV program signal, and transmits the video / audio signal of the program to the video / audio processing circuit 33. The video / audio processing circuit 33 processes the video / audio signal and outputs video and audio.
After the TV program selected by the user is output, the program branches to step S12 and waits for the next input signal to be received again. In this way, in the TV operation of the user, the processes of step S12, step S13, step S19, and step S20 of FIG. 4 are repeatedly executed.
[0052] The processing step at the time of outputting the text data signal (closed caption signal) is the same. For example, when the character broadcasting key 48 in FIG. 3 is pressed, the text character corresponding to the currently selected TV program is displayed. An instruction signal is output from the remote commander 13. When the TV receiver 17 receives this instruction signal, the reception waiting process of the input signal in step S12 is canceled, and in the following step S13, it is determined that the input signal is not a signal for setting the program guidance mode, and in step S19, It is determined that the program guidance mode is not ON, and the process of step S20 is performed.
[0053] In step S20, the control microcomputer 34 selects and demodulates the text data signal corresponding to the program specified by the user (the TV program of the channel on which the video and audio are currently output) according to the instruction signal from the user. The instruction signal to be instructed is output to the data broadcast receiving circuit 32. In response to this command, the data broadcasting receiving circuit 32 selects and demodulates the text data signal corresponding to the designated program, and transmits the text data signal to the video / audio processing circuit 33. The video / audio processing circuit 33 superimposes this text data signal on the TV video signal and outputs it to the CRT 36.
[0054] In this way, the teletext selected by the user is output.
Next, the operation of the program guidance mode using the hypertext data signal will be described.
When the user presses the program guidance key 41 of FIG. 3 once, the remote commander 13 outputs an instruction signal for setting the program guidance mode.
When the TV receiver 17 receives this instruction signal, the input signal waiting process in step S12 of FIG. 4 is canceled, and in step S13, it is determined that the input signal is a signal for setting the program guidance mode, and the process continues. Perform the process of step S14. In step S14, it is determined whether or not the program guidance mode has already been set. In this case, since the program guidance mode has not been set yet, the processing of subsequent step S15 is performed. In step S15, the control microcomputer 34 sets the program guidance mode to ON. After that, the TV receiver 17 operates in the program guidance mode using the hypertext data signal.
[0058] In the following step S16, the control microcomputer 34 acquires a control data signal (a text data signal and a corresponding hypertext data signal) for displaying the homepage from the HDD 35, and the homepage corresponding to the control data signal. The image data signal of is generated and output to the video / audio processing circuit 33.
[0059] The video / audio processing circuit 33 superimposes the above image data signal on the TV video signal being output and outputs it to the CRT 36.
[0060] FIG. 5 shows a display example of the home page screen displayed on the CRT 36 in this way.
[0061] The home page shown in FIG. 5 is composed of a text T1 using hypertext, a text T2, a TV program area A1, and a URL display unit A10.
[0062] Here, the HTML used in these texts will be described.

This file called from the text can be freely called as long as it is a file on the HDD on the client side as well as a file on the server on the network. This is the biggest feature of HTML.
[0065] As this browser, the software called MOSAIC, which was first developed by NCSA (NATIONAL CENTER FOR SUPERCOMPUTING APPLICATION) of the University of Illinois, is famous.
[0066] The WWW (WORLD WIDE WEB) of the Internet is a system using this HTML, and software such as MOSAIC can be used as an HTML browser to call and display files of WWW servers all over the world in real time.
[0067] In the WWW system used on the Internet, a network address (domain information) called a URL (UNIFORM RESOURCE LOCATOR) is assigned to a WWW server connected to the network. In addition, by attaching a tag that describes the related URL to the text described in HTML, it is possible to link to the file in the WWW server specified by the URL.
[0068] For example, simply by moving the cursor to the text linked to the file in the WWW server and clicking, the file in the linked WWW server is transferred from the WWW server to the client, and the homepage of the WWW server is displayed on the client side. Is displayed. In this way, the WWW system using HTML can easily access the WWW server on the network and handle various data such as images, sounds, texts, and moving images.
Returning to the description of the home page shown in FIG. 5, the text T1, the text T2, and the TV program area A1 are hypertexts in which related files are linked to the text characters using HTML, and these texts are Normal (files are not linked) text characters are displayed in black, for example, while they are displayed in blue, for example, which is different from this.
[0070] Text T1 represents hypertext to which a file for displaying a broadcast program guide is linked, and text T2 represents a hypertext to which a file for displaying a broadcast channel guide is linked. There is.
[0071] The TV program area A1 is for displaying the contents of the TV program of each channel corresponding to each text indicated by 1,3,4,6,8,10,12, U1, U2, BS. Represents the linked hypertext of the file.
[0072] The URL display unit A10 is an area for displaying the file name linked to the text character of the hypertext specified by the cursor.
[0073] Now that the cursor is at the position of "1" indicating the channel number 1 of the TV program in the TV program area A1 shown in FIG. 5, the file name linked to the text at this cursor position is the URL. It is displayed on the display unit A10.
[0074] By operating the up / down / left / right keys 42 to 45, the cursor is aligned with the position of each channel represented by 1,3,4,6,8,10,12, U1, U2, BS in the TV program area A1 and confirmed. By pressing the key 46, the video and audio of that channel can be output. The operation at this time will be described.
[0075] From the state of the screen shown in FIG. 5, when the user presses the right key 45 in FIG. 3 once, the remote commander 13 outputs an instruction signal for moving the cursor.
When the TV receiver 17 receives this instruction signal, the waiting for receiving the input signal in step S12 of FIG. 4 is canceled, and in the following step S13, it is determined that the input signal is not an instruction signal for setting the program guidance mode. , Step S19 is branched, and in step S19, it is determined that the program guidance mode is ON, and the process of step S21 is performed.
[0077] In step S21, it is determined whether the input signal is an HTML processing signal (signal by the confirmation key) or an update signal of the cursor position (signal by the up / down / left / right keys), and in this case, the right key. Since it is an instruction signal obtained by the operation of 45, it is determined that it is an update signal of the cursor position, and the process of step S23 is executed.
[0078] In step S23, the control microcomputer 34 generates an image data signal of the cursor display in which the position of the cursor displayed on the screen is moved by one to the right in response to the operation of the right key 45, and also , The image data signal linked to the destination text character (in this case, the text indicated by 3 in the TV program area A1) is acquired from the control data signal stored in the HDD35 and displayed on the URL display unit A10. It is generated and these image data signals are output to the video / audio processing circuit 33.
[0079] The video / audio processing circuit 33 superimposes this image data signal on the video signal being output and outputs it to the CRT 36.
[0080] In this way, the cursor moves to the position 3 to the right, which indicates the channel number 3 of the TV program in the TV program area A1, and the file name linked to the position of the cursor by HTML. Is output on the URL display section A10. In this way, the user can freely move the cursor to the target character written in HTML by operating the up / down / left / right keys 42 to 46.
From this state (the state where the cursor is at the position 3 indicating the channel number 3 in the TV program area A1), when the user presses the confirmation key 46 in FIG. 3, the remote commander 13 instructs the selection decision. An instruction signal is output.
When the TV receiver 17 receives this instruction signal, the waiting for input signal reception in step S12 of FIG. 4 is canceled, and the processing of step S21 is performed through the following steps S13 and S19.
[0083] In step S21, the control microcomputer 34 determines the type of the input signal. In this case, since it is an HTML processing instruction signal by operating the confirmation key 46, it is determined that the input signal is an HTML processing signal (signal by the confirmation key 46), and the HTML processing in step S22 is executed.
[0084] In step S22, the control microcomputer 34 acquires the corresponding executable file (file based on the control data signal) from the HDD 35 and processes this file. In this case, the file processing is the process of outputting the TV video / audio of channel number 3, so the control computer 34 sends a command to the TV broadcast receiving circuit 31 to select and demodulate the TV video / audio signal of channel number 3. The output is performed, and the above-mentioned TV video / audio output process is executed. After that, the control microcomputer 34 sets the program guidance mode to OFF, and thereafter, the TV receiver 17 operates in the TV operation mode.

[0131] Here, the operation when accessing a file on the WWW server (access point) of the Internet will be described.
[0132] For example, if the file linked to the text selected by the remote commander 13 is a file stored in a WWW server on the Internet (a file described in HTML specified by a URL), the control microcomputer. 34 makes a dial-up IP connection based on the PPP (Point to Point Protocol) plutocol to access the linked URL. That is, a connection control signal consisting of a telephone number, an ID, etc. for connecting to a pre-registered Internet service provider is output to the modem 15 via the connector 15a in a preset procedure. The modem 15 converts this connection control signal into a predetermined frequency signal conforming to the standard of the telephone line, and outputs the signal to the telephone line 16.
[0133] Then, when the dial-up IP connection with the PPP server of the Internet service provider is completed and the Internet is connected via this PPP server, the corresponding WWW server is based on the linked URL. Start access to. The HTML file such as the homepage specified by the URL transferred from the WWW server in response to this access was transmitted via the telephone line 16 via the service provider, input to the modem 15, and demodulated. After that, it is temporarily stored in the HDD 35 via the control modem 34. The control microcomputer 34 reads out the HTML file once stored, processes it, generates an image data signal such as a homepage, and outputs it to the video / audio processing circuit 33. The video / audio processing circuit 33 performs the above-mentioned superimposition processing of the image data signal and outputs the video signal.
[0134] In this way, the hypertext data signal including the URL information (domain information) is multiplexed and transmitted to the VBI of the TV video signal, so that the URL can be used as needed while watching the TV broadcast program. You can automatically connect to WWW servers on the Internet that are spread on a global scale, and you can browse a wide variety of WWW information sources by following the homepages that are linked one after another, as in the so-called Internet surfing. You can enjoy the network service.
[0135] In the above-described embodiment, the case where the television receiver is integrally incorporated has been described as an example, but the data broadcasting receiving circuit 32, the control microcomputer 34, and the control microcomputer 34 shown in FIG. 2 have been described. Of course, the expansion function part consisting of HDD35 may be configured as an expansion box such as a so-called set-top box, and may be used in combination with an existing television receiver.
[0136] Further, an example in which the HDD 35 is used as a storage means for storing hypertext data signals and the like is shown, but the magneto-optical disk using a removable magneto-optical disk such as MD (Mini Disc (trademark)) data or MO is used as a recording medium. Of course, it may be configured by using a recording / playback device. In this case, by replacing the recording medium, even a TV receiver that is not connected to the network can view the file in the same manner as described above.
[0137] As described above, it is possible to provide the user with various information services related to the TV broadcast program, including the TV program guide, by using the hypertext data signal.
[0138] As described above, the hypertext data signal including the control information for providing various information services as well as the TV receiver that processes various information services has commercial value by itself, and this hypertext data. It is also possible to set a stepwise service system corresponding to the service usage fee for the signal control content and differentiate the service according to the level of each service usage fee.
