Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 複数の端末同士を接続して行う多地点テレビ 会議において個々の端末の画像符号化レートでテレビ会 議を実現可能にする。 【構成】 複数のテレビ会議端末101〜104から送 られてくる多重化信号から画像符号化信号を分離回路1 21〜124で分離し、画像符号化処理部14に入力し て、分離された画像符号化信号をそれぞれ画像復号化器 151〜154で復号化して編集処理する。そして、端 末101〜104へ送出する画像信号を画像符号化器1 61〜164で任意のレートで符号化した後、多重回路 131〜134で他の信号と共に多重して対応する端末 101〜104へ送出する。制御部17は、各端末10 1〜104から送られてくる画像符号化レート情報に基 づき画像符号化器161〜164の符号化レートを切り 替える。 (57) [Abstract] [Purpose] To realize a video conference at the image coding rate of each terminal in a multi-point video conference performed by connecting a plurality of terminals. [Structure] A separation circuit 1 for separating an image coded signal from a multiplexed signal sent from a plurality of video conference terminals 101 to 104 21 to 124 separate and input to the image coding processing unit 14, and the separated image coded signals are decoded and edited by the image decoders 151 to 154, respectively. Then, the image signal sent to the terminals 101 to 104 is transmitted to the image encoder 1. After being encoded at an arbitrary rate by 61 to 164, they are multiplexed with other signals by the multiplexing circuits 131 to 134 and transmitted to the corresponding terminals 101 to 104. The control unit 17 controls each terminal 10 The encoding rates of the image encoders 161 to 164 are switched based on the image encoding rate information sent from 1 to 104.
