Transmission processing apparatus, television conference system, transmission processing method and memory medium

摘要

There is disclosed a system capable of dispensing with the video/audio encoder in each communication terminal. A switch selects one of plural video/audio inputs. A video capture device of a transmission apparatus digitizes the selected video signal. A video encoder effects compression-encoding of the video capture device according to motion JPEG, MPEG and H.261. A selector sets compression video data to be transmitted, among the video data compressed by different encoding methods, and sends such data to a communication buffer. An audio encoder digitizes and encodes the selected audio signal and sends such signal to the communication buffer. The encoded video and audio data of the communication buffer are read to a network. A control circuit controls devices according to control commands received through the network.
