Incidentally, when the image by the network service is not output and displayed on the CRT 43, the instruction command by the operation of the trackball K7 and the click key K8 is ignored.

Next, referring to the flowchart of FIG.
The processing operation of the TV receiver 21 will be described.

First, the TV receiver 21 outputs a TV broadcast signal in which neither the character data signal nor the signal including the URL information is multiplexed in the VBI of the TV video signal from the TV broadcast station. The operation and the corresponding processing operation will be described.

The user selects the remote commander 2 shown in FIG.
After operating the power key K1 of No. 3 and operating the number keys K2 or the channel UP / DOWN key K4 to instruct to select a predetermined TV broadcast channel, in step S1 of FIG. It is input to the microprocessor 34 via the light receiving unit 45 of the image receiver 21.

Correspondingly, the microprocessor 34
Outputs to the tuner 31 a channel selection command for the specified TV broadcast channel. According to this channel selection command, the tuner 31 selects a predetermined TV broadcast channel and outputs an audio signal and a video signal to the video / audio selection circuit 33.

In the next step S2, the video signal control circuit 41 converts the video signal input from the video / audio selection circuit 33 into an RGB signal and outputs it to the RGB signal amplification circuit 42. Then, this RGB signal is amplified by the RGB signal amplifier circuit 42 and then output to the CRT 43.

The audio signal is input to the audio signal amplifier circuit 33 via the video / audio selection circuit 41, amplified by this circuit, and then output to the speaker 44.

Subsequently, in step S3, the microprocessor 34 determines whether or not the signal is multiplexed with the VBI of the TV video signal (determines whether or not data is input from the VBI data slicer 32). In the present case, TV
Since the signal is not multiplexed with VBI of the video signal, N
O is determined, and the user's operation in processing the TV broadcast signal in this case ends.

In this way, the TV broadcast channel T
The V image is output and displayed from the CRT 43, and the TV sound is output from the speaker 44.

In FIG. 5, CR is processed by the processing of step S2.
It shows one display example of the screen displayed at T43.

The character string A in FIG. 5 represents the URL transmitted as a part of the image in the TV video signal. In addition to displaying the URL, it may be announced as an output of a TV audio signal.

As described above, if the URL of the network service provider that provides the service related to the TV broadcasting channel is displayed on the CRT 43, the URL is manually input from the keyboard on the personal computer of each home,
It is also possible to connect to the access point indicated by this URL and receive services related to TV broadcast channels.

However, manually inputting the URL is inconvenient and inconvenient. Therefore, the broadcasting station
At the same time that L is broadcast as a part of the image, it is also transmitted as BVI.

Then, next, in the present state, when the TV broadcasting station outputs the TV broadcasting signal in which the URL information is multiplexed in the VBI of the TV video signal, the operation of the TV receiver 21 and the corresponding processing. The operation will be described.

The microprocessor 34 performs the processing of steps S1 to S3, as in the case described above. In this case, YES is determined in step S3,
Further, in step S4, when outputting the character data signal, the microprocessor 34 outputs and displays it.
In step S5, it is determined whether or not a signal including URL information is multiplexed in VBI. In this case, a YES determination is made, and in step S6, the microprocessor 34
Stores the URL information in the RAM 35. Further, the microprocessor 34 outputs the OSD data to the video encoder 37 and causes the CRT 43 to display the character string B as shown in FIG. 6, for example.

The character string B in FIG. 6 is VBI of the TV video signal.
The signal containing the URL information is multiplexed in the
It informs the user that the signal including the L information is received by the TV receiver 21. In this way, the user can recognize that the signal including the URL information has been received.

Subsequently, in step S7, the user
Whether to connect to the network service during the period when L (character string A) is displayed (or within a certain time (this time is transmitted by BVI or is set to a predetermined value in advance)) Determine whether or not. If the user determines not to connect, the subsequent operations are terminated. The microprocessor 34 determines that the character string B
Is erased from the screen. Also, the character string A is deleted at a predetermined timing (the broadcasting of the URL is ended). Even if the user operates the connection key K5 after the character string A is erased (or after a certain period of time elapses), the operation is ignored and the connection processing as described later is not performed.

When the user determines to connect to the network service, the connection key K5 of the remote commander 23 is pressed in the state of the screen shown in FIG. 6 (while the URL is displayed (or within a certain period)). To do. At this time, a YES determination is made in step S7, and step S
Branch to 8.

In step S8, an instruction signal corresponding to the operation of the connection key K5 is input to the microprocessor 34 via the light receiving section 45. In response to this, the microprocessor 34 reads the URL information from the RAM 35, and
The communication signal for connecting to the access point corresponding to the RL is output to the data modem 38. Data modem 38
Modulates this communication signal and outputs it to the telephone line through the modular jack 24. At this time, the microprocessor 34 outputs character data (OSD data) for notifying the user of the start of the connection process to the video encoder 37. This character data is input to the video signal control circuit 41 via the video encoder 37 and the video / audio selection circuit 33, superimposed on the TV video signal, and RG
It is output to the CRT 43 via the B signal amplifier circuit 42.

FIG. 7 shows a display example of the screen output and displayed on the CRT 43 in this way. Character string C in FIG.
Indicates that the character data output from the microprocessor 34 is output as an image, and that the connection processing has started.

Subsequently, in step S9, after connecting to the access point corresponding to the URL, the processing data corresponding to the network service is transmitted from the access point through the telephone line, and then through the modular jack 24 and the data modem 38. Is input to the microprocessor 34.

In subsequent step S10, the microprocessor 34 processes the processed data to generate video data and audio data corresponding to the network service, outputs the video data to the video encoder 37, and outputs the audio data to the audio encoder. Output to 39. At this time, the microprocessor 34 causes the video / audio selection circuit 33 to stop the output of the TV video signal. The video signal encoded by the video encoder 37 is a video signal.
/ Audio selection circuit 33, video signal control circuit 41,
And to the CRT 43 via the RGB signal amplification circuit 42. The audio signal modulated by the audio encoder 39 is output to the speaker 44 via the video / audio selection circuit 33 and the audio signal amplification circuit 40.

In this way, the screen shown in FIG. 7 is deleted, and instead, the screen for providing the network service generated by processing the processed data is displayed on the CRT 43. Further, the voice corresponding to the network service is output from the speaker 44.

FIG. 8 shows a display example of the network service providing screen (home page) displayed on the CRT 43 in this way.

The screen shown in FIG. 8 represents a home page that provides information about the "house" displayed on the screen shown in FIG. Further, the microprocessor 34 displays a cursor D for selecting various services from the home page on this screen.

When the user operates the trackball K7 of the remote commander 23 on the screen shown in FIG. 8, an instruction command corresponding to the operation is input to the microprocessor 34. The microprocessor 34 generates video data for moving the cursor D in the direction corresponding to the operation of the trackball K7, and outputs the video data to the video encoder 37. In this way, the cursor D moves in response to the operation of the trackball K7.

When the user operates the trackball K7 to move the cursor D to a predetermined position and then presses the click key K8, a corresponding instruction signal is input to the microprocessor 34 and the microprocessor 34
Executes the process corresponding to the position of the cursor D. If the process corresponding to the position of the cursor D is further requesting another network service, the microprocessor 34 again sends the request signal to the access point via the data modem 38 and the modular jack 24. Is transmitted over the telephone line.

Thereafter, the microprocessor 34 receives the processed data transmitted from the access point corresponding to the predetermined URL via the data modem 38, processes the processed data again, and outputs the video data and the audio data corresponding to the service. Video encoder 3 respectively
7 and the audio encoder 39.

In this way, the microprocessor 34
Performs processing corresponding to the position of the cursor D, and appropriately acquires processing data via the data modem 38 as needed.

When terminating the network service,
The user moves the cursor D to a predetermined icon on the display screen by operating the trackball K7, and then presses the click key K8, whereby the macro processor 3
4 is instructed to end the network service.

The microprocessor 34 proceeds to step S1.
1 corresponds to this, the video / audio selection circuit 3
3 is controlled to start the output of the TV video signal. In this way, the TV video output processing and the TV audio output processing are restarted, and as a result, the TV video screen as shown in FIG. 5 is again displayed on the CRT 43.

In this way, the VBI of the TV video signal is multiplexed with the signal containing the URL information and transmitted, so that the TV broadcast program can be viewed and, if necessary, the URL.
It is possible to automatically connect to the access point corresponding to and to enjoy the network service.

At this time, the user is required to make a U consisting of a plurality of characters.
RL does not need to be operated by operating multiple keys.
Since the connection process is started only by operating one connection key K5, the operability is improved. Further, since the operation is simple, the service provider can expect access from more users.
