FIG. 3 is a diagram showing an example of the operation unit of the remote commander 13.

The operation section is composed of a program guide key 41, up / down / left / right keys 42 to 45, a decision key 46, a ten-key pad 47, and a teletext key 48.

The TV receiver 17 shown in FIG. 2 operates in a TV operation mode in which control is performed by a TV operation similar to the conventional one, and a program guide mode in which control is performed using a hypertext data signal.

The program guide key 41 is for selecting a program guide mode,
This is a switch key for switching between the TV operation mode and the TV guide mode.
The operation mode is switched.

The selection of TV programs and the selection of teletext in the TV operation mode are performed by the up / down keys 42, 43, the ten-key pad 47, and the teletext key 48. For example, the user may use the up key 42 (or down key 43)
Press once to enter the T of the next (or previous) channel
When the V program is selected or one 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 TV program is selected. The text data signal (closed caption signal) multiplexed with the video / audio signal of the TV program of the selected channel is selected and the text character is 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 key is operated to determine the control content.

Next, a specific operation using this operation unit, the processing operation corresponding to the operation, and the display screen will be described with reference to the drawings starting from FIG.

FIG. 4 is a flow chart for explaining the processing operation of the TV receiver 17.

First, the operation in the TV operation mode will be described.

When the user presses a power switch (not shown) to put the TV receiver 17 into an operating state, the operation mode of the TV receiver 17 is TV in step S11 of FIG.
The operation mode is initialized. Further, in this state, the state when the user turned off the power switch (not shown) of the TV receiver 17 last time is held in the memory in the control microcomputer 34, and at that time, the channel selection is performed. The video and audio of the TV program of the selected channel is output as a default.

In a succeeding step S12, a reception waiting process for the input signal from the user is performed, and the video and audio of the TV program of the channel initially set in the step S11 is continuously output until the instruction signal is input from the user. .

From this state, the user presses the upper key 42 of the operation unit shown in FIG. 3 for the purpose of selecting a TV program.
When pressed twice, the TV receiver 1 is received from the remote commander 13.
An instruction signal is output to 7.

When the TV receiver 17 inputs this instruction signal, the reception waiting process of the input signal in step S12 is canceled, and in step S13, the control microcomputer 34 of the TV receiver 17 receives the program whose input signal is shown in FIG. It is determined whether or not the signal is from the guide key 41. In this case, since the input signal is the TV operation signal for instructing the selection of the TV program, it is determined that it is not the instruction signal by the program guide key 41, and the process of step S19 is performed.

In step S19, it is determined whether the program guide mode is set. In the present case, TV
Since the receiver 17 is operating in the TV operation mode, it is determined that the program guide mode is not set, and the subsequent step S20 is executed.

In step S20, the control microcomputer 34 selects the TV program of the channel designated by the user (in this case, the TV program of the next channel) to the TV broadcast receiving circuit 31 in accordance with the instruction signal from the user. A command signal to instruct is output. In response to this command, the TV broadcast receiving circuit 31 extracts and demodulates the specified 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 process branches to step S12 to wait 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.

The processing steps at the time of outputting the text data signal (closed caption signal) are also the same. For example, when the teletext key 48 in FIG. 3 is pressed, the text characters corresponding to the TV program currently selected are displayed. An instruction signal for instructing is output from the remote commander 13. When the TV receiver 17 receives this instruction signal, the reception waiting process for the input signal in step S12 is canceled, and in the following step S13, it is determined that the input signal is not the signal for setting the program guide mode, and in step S19, It is determined that the program guide mode is not ON, and the process of step S20 is performed.

In step S20, the control microcomputer 34 follows the instruction signal from the user to select and demodulate the text data signal corresponding to the program specified by the user (the TV program of the channel where the video and audio is being output now). The command signal to instruct is output to the data broadcast receiving circuit 32. In response to this command, the data broadcast receiving circuit 3
2 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 the text data signal on the TV video signal, and the CRT 3
6 is output.

In this way, the teletext selected by the user is output.

Next, the operation of the program guide mode using the hypertext data signal will be described.

When the user presses the program guide key 41 in FIG. 3 once, the remote commander 13 outputs an instruction signal for setting the program guide mode.

When the TV receiver 17 receives this instruction signal, the input signal waiting process in step S12 of FIG. 4 is canceled, and it is determined in step S13 that the input signal is a signal for setting the program guide mode, and the process continues. The process of step S14 is executed. In step S14, it is determined whether or not the program guide mode has already been set. In this case, since the program guide mode has not been set yet, the processing of the subsequent step S15 is performed. In step S15, the control microcomputer 34 sets the program guide mode to ON. After that, the TV receiver 17 operates in the program guide mode using the hypertext data signal.

In the next step S16, the control microcomputer 34 obtains a control data signal (text data signal and hypertext data signal corresponding thereto) for displaying the homepage from the HDD 35, and the homepage corresponding to this control data signal. Image data signal is generated and output to the video / audio processing circuit 33.

The video / audio processing circuit 33 superimposes the above-mentioned image data signal on the TV video signal being output, and outputs the CRT 36.
