Abstract

PURPOSE: To obtain the synthesized picture without complicated total processing, by synthesizing various picture infomation transmitted from the transmission terminal of a plurality according to the form of video information suitably.
CONSTITUTION: Picture information is delivered from a plurality of transmission terminals 11a∼11n. This picture information is attached with the period signal indicated with the base mark 24 specifying the position of picture other than the picture infomation and the mark 25 indicating the identifying signal is added to right upper position of one picture. The types-of-synthesis detection circuit 14 detects and discriminates the indetifying signal and selectively determines the instruction signal of synthesized form on the type of picture among the synthesized form set and it is outputted to the operation unit 18 as control signal. Further, the synchronizing information detection circuit 15 detects the synchroning signal and outputs the reference timing information to the operation unit 18. The synthesized video signal thus obtained with this operational processing is outputted to the communication outgoing lines 12a∼12n.
