The read image and audio are processed at the signal reproducing level by the signal processing unit 74, and the audio signal processing unit 68 and the image signal processing unit 70 are later processed by the A / V switching unit 67. Processing is performed on the speaker device and the CRT device.

On the other hand, when the 'REC' button 22 of the remote controller keypad 10 is operated, the video and audio of the broadcast signal transmitted through the A / V switching unit 67 are transmitted from the signal processor 74. After being processed to the recording signal level, it is recorded on the video tape 72 by a recording head (not shown) of the signal recording / reading unit 73. When the reservation recording mode is set by operating the reservation recording button (not shown) of the remote controller keypad 10, the control unit 61 and the channel number designated by the 10-key 15 in the reservation recording mode. Receives the reservation recording time data (recording start time and recording end time) and stores them in the data storage unit 75. When the time data provided by the timer 76 reaches the recording start time, the tape driving mechanism ( 71 is tuned by applying tuning data corresponding to the channel number to the tuner 65, and the video and audio of the tuned channel are IF processed by the video and audio IF modules 66 and 69. The recording time corresponding to the recording end time on the video tape 72 is applied to the signal processing unit 74 through the A / V switching unit 67 and is post-processed. Taped across It is to run. Here, the control state such as rewinding, winding or reproducing the video tape 72 is visually displayed on the display unit 77 constituted by the fluorescent display panel under the control of the control unit 61.

On the other hand, if the call button 41 of the door vision panel 40 is operated during the playback of the video tape 72 in step 102 (step 103), the CPU 43 calls through the call signal output unit 44. A signal is outputted to the control unit 61 so that, for example, a call state by the visitor by the OSD processing unit 63 is displayed on the CRT device as an OSD signal, and when the call signal is applied to the control unit 61, The control unit 61 controls the tape driving mechanism 71 so that the video tape 72 in the playback state is in the still mode, while the audio processing path of the A / V switching unit 67 is controlled by the door vision side. Allocate a call signal applied from.

Therefore, in step 104, when the viewer inputs a voice for confirming the visitor through the microphone 17 under the manipulation of the visitor mode selection 16 on the remote control keypad 10 in response to the call signal, the call signal amplification of the remote controller is performed. The unit 34 amplifies the viewer's voice and carries out carrier modulation in the call signal modulator 35 which is activated and controlled by the controller 61 when the call signal arrives, and the modulated voice signal is converted into a call signal transmission unit ( 36) is transmitted to the call signal receiver 45 of the door vision.

The call signal receiver 45 applies the received viewer's voice to the call signal demodulator 46 which is activated and controlled by the CPU 43. The call signal demodulator 46 demodulates the viewer's voice. After being amplified by the amplifier 47, the speaker 47 is delivered to the visitor.

Subsequently, the voice input by the visitor is processed by the visitor call signal processing unit 49 of the door vision side and amplified by the amplifying unit 50, and then the amplified visitor voice signal is transmitted through the interface 51. It is applied to the audio signal processing unit 68 through the / V switching unit 67 and is reproduced, and the visitor audio signal is applied to the speaker device of the television and reproduced, and the voice call between the viewer and the visitor is possible by such a process. Done ..

The control unit 61 performs normal playback of the video take 72 in the still mode under the control of the tape driving mechanism 71 in step 106 when the viewer and the visitor end the voice call (YES in step 105). If possible, disassemble the still mode.

Here, the end of the voice call may be executed by, for example, re-operation of the visitor mode button 16 provided in the remote controller keypad 10, but the level of the visitor voice signal processed by the voice signal processor 68 is detected. Or other appropriate methods may be applied.
