Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment according to the present invention.

Fig. 1 is a block diagram of a recording apparatus of a video telephone / video cassette recorder composite system according to the present invention, which is composed of a caller side video telephone 100, a caller side video telephone 200, and a video cassette recorder 300. .

At this time, the caller-side video phone 100, when the caller hooks off the handset 110, the processor 120 detects the hooking off signal of the handset 110 and through the caller's voice information and the camera 130 is input Compressed image information is provided through the trunk line, and the image information and voice information of the called party are restored, and the image information is displayed on the screen through the monitor, and the audio information is output through the handset.

On the other hand, the processor 220 of the caller-side video phone 200 provides a signal for the call to the microcomputer 250 when a call is received from the caller-side video phone 100, and thus the microcomputer 250 receives a video cassette. The receiver image information and the guidance message recorded in the recorder 300 are provided to the processor 220. Therefore, the processor 220 compresses the provided image information and the voice information for the guidance message and sends the compressed information to the caller side image telephone 200.

At this time, the processor 120 of the caller-side video telephone 100 restores the image information and the audio information provided through the trunk line and provides the same through the monitor 140 and the handset 110. In addition, when the caller reception message is provided through the handset 110, the processor 120 compresses and provides the message information of the caller provided through the camera 130.
