Abstract

다중채널 이미지 압축시스템은 이미지 데이터를 압축하기 위해 다수의 인코더(10,12,…,14)를 이용하고, 코딩레벨명령은 각 인코더에 의해 제공되는 품질의 레벨을 특정하도록 각 인코더에 제공되며, 코딩레벨명령에 응답한 인코더에 의해 제공된 인코드된 이미지 데이터는 전송을 위해 혼합신호로 멀티플렉스된다(26). 그리고, 코딩레벨명령은 통신채널(48)의 처리능력내에 축적된 데이터를 유지하도록 혼합신호로부터 축적된 데이터의 양에 응답하여 조절된다. 또한, 코딩레벨 명령이 모든 인코더에 대해 동일한 그로벌 코딩레벨을 특정함에도 불구하고, 인코더는 다른 인코딩 픔질을 제공하도록 그로벌 코딩레벨로부터 로칼 코딩 레벨을 추출할 수 있게 된다. 그리고, 디코더장치(30∼46)는 압축된 이미지 데이터로부터 이미지를 복구하도록 제공된다.
