In the figure, the telephone 80 connects the A / V terminal of the VAL 100 and the external telephone line 50, and the ring signal input from the exchanger and the hooking operation of the user. Accordingly a hook signal is applied to the microcomputer 114.

The key input unit 102 includes a mode selection key for controlling various operations (playback, recording, still, etc.) of the V200, and outputs a key signal corresponding to the user's key operation.

The decoder 104 decodes the video and audio signals input from the telephone line 50 into general TV signals and outputs them to the OSD (On Screen Display) 110 and the speaker 112.

In response to the control signal of the microcomputer 114, the recording processing system 105 separates the signal from the signal input from the telephone line 50 into luminance and color signals so as to record the image signal on the video tape and removes the noise and the signal. The amplified signal is combined with the luminance and color signals and output to the deck driver 106. The recording processing system 105 also performs signal conversion and amplification for recording audio signals, respectively.

Deck drive unit 106 is controlled by the microcomputer 114, the various operations of V-Cal (100). In addition, the deck driver 106 records the video or audio signal supplied from the recording processing system 105 on the video tape using the rotating head, and the image recorded on the video tape according to the control signal of the microcomputer 114. Alternatively, the audio signal is read and output to the reproduction processing system 108.

The reproduction processing system 108 processes the image signal read out from the deck driver 106 into a displayable signal and applies it to the OSD 110 according to the control signal of the microcomputer 114. In addition, the reproduction processing system 108 processes the audio signal read out from the deck driver 106 into a signal capable of outputting the signal and outputs the signal to the speaker 112, and synchronizes the timing of the audio signal with the image signal. ).

The OSD 110 is a device for processing characters on the screen. The OSD 110 synthesizes image signals output from the reproduction processing system 108 or the decoder 104 and the corresponding character signals due to the character control signals from the microcomputer 114. Output to monitor (not shown).

The speaker 112 outputs the audio signal applied from the reproduction processing system 108 or the decoder 104 to the outside.

The microcomputer 114, on the other hand, outputs a control signal for forming a telephone loop selectively in response to the hook signal from the telephone 80 to each component located in the VRC.

In addition, the microcomputer 114 records the image and audio signals input from the external telephone line 50 on the video tape according to the key signal input from the key input unit 102, or the image and audio signals recorded on the video tape. Read and play the control to control the output to the OSD (110) and the speaker (112).

In detail, when a reproduction key signal is applied from the key input unit 102, the deck driver may process the image and audio signals recorded on the video tape into outputable signals and provide them to the OSD 110 and the speaker 112. 106 and the reproduction processing system 108 are respectively controlled. If the recording key signal is applied from the key input unit 102, the microcomputer 114 causes the deck drive unit 106 to record the video and audio signals amplified / converted by the recording processing system 105 on the video tape.
