In the case of the corresponding lake information, the received video and audio signals are input to the second binary signal converter 230.

Then, the second binary signal converter 230 demodulates the received video and audio signals into the original signal, and the demodulated signal is output to the decoder 240, and the decoder 240 reconstructs the encoded video and audio signals. It decodes and converts the original analog video signal and the audio signal.

The analog video signal and the audio signal converted as described above are amplified by the audio amplifier 250 and the video amplifier 260 and then output to the speaker and the monitor so that users within the household can check the visitor.

At this time, the home video phone 200 installed in each generation is provided with a keypad that can perform various functions such as numeric key buttons, shortcut buttons that can be directly connected to the guard room or management room, or a common entrance door open command button. As described above, a monitor and a speaker are also provided.
