弱いという欠点があった。As a result, video signals were converted into electrical signals and transmitted and received as electrical signals. Therefore, complex control is required to convert electrical signals to video signals, and the transmission speed is also high, so a wide frequency band is required. First, since video signals, audio signals, and control signals are transmitted and received as electrical signals, they have the disadvantage of being more susceptible to noise than optical signals.

したら光スイッチによυ発呼側と被呼側とを接続する。Referring to FIGS. 1 and 2 showing an embodiment of the present invention, in the initial state when the videophone device 100 is turned on,
From the optical control signal 205 on the housing switching device side, the synchronization unit 110K
to synchronize. When making a call from the videophone device 100, the control unit 10 controls the call and changes in the state of the keys 108, etc.
9, and the control unit 109 sends outgoing information, dial information, etc. to the synchronization unit 110. The synchronization unit 110 converts it into an optical signal and sends it to the switching device side in synchronization with the sending timing of the optical control signal 202. The image of the caller at this time is converted into an optical image color code by the camera 103, amplified by the optical amplification section 104, and sent to the synchronization section 110. 1, the caller's voice is converted from air vibration into an electrical audio signal by the microphone 105, and further converted from the electrical audio signal to an optical audio signal by the converting section 107, and sent to the synchronization section 110. The synchronization unit 110 synchronizes the optical video signal 200,
An optical audio signal 201 is sent out. The exchange equipment side controls the called side using dial information etc. from the calling side, and when the called side answers, the optical switch connects the calling side and the called side.

。The called party then sends an optical video signal and an optical audio signal to the calling party. Optical video signal 2 sent to the called party
03 and the optical audio signal 204 are received by the synchronization unit 110 on the calling side via the optical cable 111. The optical video signal of the called side is sent to the optical amplification section 102, and further sent to the display section 101, where the image of the called side is displayed. Further, the optical audio signal from the called side is sent to the conversion unit 107, where the optical audio signal is converted into an electrical audio signal, and further converted into air vibration by the speaker 106. By the above operation, the calling party and the called party can talk while viewing the image of the other party. Further, in the case of the end of the call, the control unit 109 detects the end of the call, stops the optical video signal and the optical audio signal, and notifies the end of the call information to the switching device side. When the exchange equipment side detects the call termination information, it disconnects the optical switch connecting the calling side and the called side, and the call ends.
