Abstract
본발명은 화상 통신 시스템에 있어서 하나의 중앙처리장치를 이용하여 송,수신이 가능하게 하는 시스템에 관한 것으로 기존의 화상 통신 시스템에 대역통과 필터 (36A) (36B), 저역통과 필터(46) 및 후크 스위치 감지부 (48)를 추가하고, 중앙처리장치(38)가 상기 후크스위치 감지부(48)를 통해 통화의 시작, 종료신호를 공급받으며, 상기 압축데이타 메로리부(35A) (35B)로 부터 풀신호, 엠티신호가 공될 때 송, 수신부 (300) (400)를 제어하여 화상 통신이 이루어지게 함으로써 최소한 중앙처리장치로 화상 통신을 실현할 수 있다.The present invention relates to a system that enables transmission and reception using a central processing unit in a video communication system. The present invention relates to a band pass filter (36A) (36B), a low pass filter (46), and a conventional video communication system. The hook switch detection unit 48 is added, and the central processing unit 38 receives the start and end signals of the call through the hook switch detection unit 48, and the compressed data memory unit 35A (35B). When the full signal and the empty signal is provided from the transmission and reception unit 300, by controlling the video communication is achieved by at least the central processing unit can realize the video communication.
