Inter-multi points tv conference system

Abstract

Abstract PURPOSE:To enable to watch a clear image of one facing point desired as well as enable to catch a whole atomosphere of a conference at any time by switching the picture synthesized plural facing point pictures and one desired picture of the plural facing point pictures and by displaying said picture utilizing a simple terminal of one monitor. CONSTITUTION:When a picture form of the picture 20 synthesized th video signal from each facing point (a), (b), (c) and (d) is requested, four input video signals 30a, 30b, 30c and 30d from the TV conference terminal (a), (b), (c) and (d) are selected by the switching circuit 33 synthesized in one picture at the synthesize circuit 32 after being reduced to 1/2 lengthwise and sideways in the reducing circuits 31a, 31b, 31c and 31d. On one hand, when any one of picture from each facing (a), (b), (c) or (d) is requested, the video signal requested among four input video signals from the TV conference terminals (a), (b), (c) and (d) is selected by the circuits 33 to output.
