ABSTRACT:
A television conference system includes, in a transmitting side, a plurality of TV cameras assigned with camera ID codes, and in a receiving side, a plurality of TV monitors assigned with monitor ID codes and frame memories for storing inputs to the TV monitors. In the transmitting side, a moving picture signal output from a TV camera selected by a camera ID number is encoded, and the encoded moving picture signal together with a monitor ID code of a TV monitor designated to display an output from the selected TV camera are transmitted to the receiving side. In the receiving side, writing is performed in a frame memory corresponding to the TV monitor designated by the monitor ID signal to display a moving picture on the TV monitor, writing in each of the frame memories corresponding to the other TV monitors is inhibited and the last frame of the latest moving picture displayed thereon is displayed as a still picture, and selection of the TV camera and designation of the TV monitor are arbitrarily performed.
