Control the volume down.

Next, the operation of the present invention made as described above will be described in detail with reference to the flowchart of FIG. 3.

First, in step 50, when a predetermined channel is tuned through a tuner (not shown), the intermediate frequency conversion is performed, and the intermediate frequency amplification processing is performed, the image signal processing unit 2 separates the composite video signal from the television broadcast signal of the predetermined channel and outputs the image. As the signal is processed, the image is reproduced through the CRT, and the voice signal processor 30 processes the voice signal separated from the television broadcast signal to reproduce the voice through the speaker.

In this state, the flow advances to step 51 and the mode key 38 of the function setting unit 36 is key operated so that the program information audio transmission mode is set. The synchronizing signal component is separated from the composite video signal of, and the data slicer 6 extracts the teletext information included in the vertical blanking period by the separated synchronizing signal, while the data determination unit 8 extracts the extracting information. The data determination signal is generated as a result of determining the data type of the broadcast program sound transmission information from the received teletext information.

Then, the teletext decoder 12 is controlled by the program memory 14 to decode the broadcast program voice transmission information according to the teletext information based on the character code data stored in the character memory 16 to channel the program. As the data is converted into character code data according to the information, the control unit 44 receives the data determination signal from the data determination unit 8, recognizes the reception state of the broadcast program voice transmission information, and then outputs the character code memory 22. ), The character code data corresponding to the channel program information decoded by the teletext decoder 12 is stored in the character code memory 22.

At this time, the process proceeds to step 52, in which the mode key 38 of the function setting unit 36 is key operated to determine whether or not the predetermined predetermined time has elapsed since the program information sound transmission mode is set.

As a result of the determination in step 52, if it is determined that the predetermined time for executing the mode has elapsed after the program information voice transmission mode is set, then control proceeds to step 53 and broadcasts immediately after the broadcast program broadcast on the currently reproduced broadcast channel. As the control data DA and the address ADD are generated in the character code memory 22 in order to transmit the broadcast program information, the voice converter 26 reads out the character code memory 22 from the character code memory 22. The audio code data corresponding to the converted character code data is read out from the voice code memory 24 and combined with each other so as to be converted and processed as a voice signal according to the channel program information, and subjected to analog conversion through a decoding process by the voice decoder 28. The signal amplification operation of the signal amplifier 34 is performed by adding the voice signal and the signal from the voice signal processor 30 through the adder 32. Through the speakers as a parameter alarm is played.

At this time, the controller 44 applies the volume control signal to the voice signal processor 30 so that the volume of the voice signal according to the television broadcast is lowered by a predetermined value.

However, if it is determined in step 52 that the predetermined time has not elapsed under the program information sound transmission mode, then control proceeds to step 54 where the 10-key 40 of the function setting unit 36 is key operated. It is determined whether other broadcast channels other than the currently reproduced broadcast channel are selected.

As a result of the determination in step 54, when it is determined that the 10-key 40 of the function setting unit 36 is being operated for selecting other broadcast channels, the control proceeds to step 55, and the broadcast channel is not currently reproduced. The character code memory 22 is controlled to transmit only a limited amount of channel program information for a program to be broadcast immediately after the currently broadcast program of the broadcast channel selected by the key operation of the function setting unit 36. As the data DA and the address ADD are generated, the character code read out from the character code memory 22 is converted into a voice signal by the voice converting section 26 and sent out.

According to the present invention made as described above, not only the broadcast channel currently reproduced on the television, but also other broadcast channels, so that program information on the broadcast program broadcasted later can be reproduced in the form of a voice by a simple key operation. As a result, it is possible to more easily recognize program information of a television broadcast to be watched later.
