ABSTRACT:
A system for automatic telephone answering picture/sound recording and a device therefor records both a television program and an incoming message from a calling party on a common video tape. Upon detection of a telephone ringing signal, the telephone line is engaged and then, to effect picture/sound recording of a telecast, the video tape is set in a standby mode, and at the same time an outgoing message is transmitted. Upon completion of the transmission of the outgoing message, the standby mode is cancelled to operate the recording section and then the incoming message is recorded on the video type. Further, restoration to a standby mode is made after the message recording is completed.
