The data collected or secured as described above is input to the first data processor 20 embedded in the transceiver main body 14 to convert analog signals such as video and audio into digital signals at the input unit 22 of the processor (S104). ).

The data converted into the digital signal in this way is compressed by the compressor 22 using a codec program (S106).

As described above, the data compressed by the compressor 24 classifies each converted signal by using the MUX program in the converter 26, converts it into one transmission signal, and gives an ID (S108). ).

(S112). Here, the user or video conferees arbitrarily decides whether to use an optical cable or a laser to select a transmission method.

The data signal transmitted from one transceiver T1, that is, the optical signal, is received by the second data processor 30 through the reception lens 18 of the other transceiver in communication or another transceiver T2 adjacent to each other. In operation S114, the optical signal 32 converts the optical signal data into an electric signal.

Then, the electrical signal, that is, the data converted into a digital signal is separated by the ID given to each signal in the separator 34 (S116).

The digital signal identified and separated by ID is converted into a recognition signal such as an analog signal by the converter 36 (S118). Here, the converter 36 converts the digital signal separated for each ID by a codec program built into the converter into a signal that can be recognized by a user, that is, a signal such as an image, an image, a text, and an audio.
