In addition, the current channel fixed control signal VT1 and the variable tuning control signal VT2 of the microcomputer 12 are connected to the tuning control stage of the tuner eye unit 13 connected to the tuning control port of the microcomputer 12.

On the other hand, the system is provided with an audio listening control processing program 100 as shown in FIG.

The audio listening control processing program 100 checks whether the microcomputer 12 checks whether the current operation mode is the VSI playback mode and executes the playback operation if it is in the playback mode (steps 101 and 102). If the recording mode is checked and the recording mode is checked, steps of executing a recording operation (steps 103 and 104) are performed. Then, the user checks whether there is a broadcast audio mode key input from the key input unit 11 by the user. Checking whether there is an input (step 106), and if there is a channel key input by the user, receiving the corresponding channel, and synthesizing the OSD signal generated through the OSD unit 17 with the reproduced video signal to display the channel number and Outputting the OSD display indicating that audio is being output together with the playback screen, and switching the existing line to a broadcasting system audio line (step 107, 108) and checking whether the broadcast audio mode selection key is input again, and releasing the broadcast audio mode when the input is recognized (steps 109 and 110).

In the present invention, the user presses the playback key or the recording key through the key input unit 11 as shown in FIG. 2 to perform tape playback or recording using the VSI system.

By the user's key input, the microcomputer 12 recognizes whether the current mode is the playback mode or the recording mode, and performs the tape playback or recording operation through the deck unit 15 or the like.

When the system performs the playback operation, the signal reproduced from the deck unit 15 is amplified and demodulated by the audio / video processing units 16 and 18, and then the AV is passed through the switch unit 14 to the rear of the audio / video signal. If it is provided to the output of the playback screen to the TV receiver through the modulator of the rear stage.

In this state, when the user wants to check what the broadcast program is being received in the broadcasting system, the user presses an audio listening key provided in the key input unit 11 and selects a broadcast channel that he / she wants to listen to.

When the system recognizes the user's audio listening key press and channel key input, the microcomputer 12 sends the channel fixing control signal VT1 to the tuner eye F 13 through the tuning control port, and the corresponding channel is tuned to the tuner eye F. The unit 13 provides only the audio signal of the corresponding channel to the AV switch unit 14, and the audio signal of the channel broadcast tuned through the AV switch unit 14 is output.
