Title: 화상전송장치및그것을사용한화상전송시스템
IPC: H04N7/18
Filed: 1999-02-19
Abstract: 저데이터 전송 속도의 회상으로 수신측으로 송신되는 압축 비디오 데이터에 시간 지연이 발생하는 것을 방지한 화상 전송 장치가 개시되어 있다. 
     송신측 카메라(21)로 감시 대상을 촬상한다.  카메라(21)로부터의 비디오 신호(SVi)를 압축부(22)에서 처리하여 압축 비디오 데이터(DV)를 생성하고, 이 데이터(DV)를 회선(40)을 통해 수신측으로 송신한다.  수신측에서는 데이터(DV)를 신장부(31)에서 처리하여 비디오 신호(SVr)를 얻고, 그것에 의한 화상을 모니터(32)에 표시한다.  수신측에서 감시자가 MMI(33)를 조작하여 얻은 팬틸터(23)의 제어 신호(PTC)를 회선(40)을 통해 송신측으로 송신하고 송신측 카메라(21)의 촬상 방향을 MMI(33)의 조작에 대응하여 변경한다.  카메라(21)의 촬상 방향이 변경되어 있는 상태에서는 화면 변화가 커지지만, 송신측 압축부(22)에서의 데이터 압축율이 높아지도록 제어하여 데이터량의 증가를 억제한다.  이것에 의해, 수신측으로 송신되는 압축 비디오 데이터(DV)의 시간 지연이 방지된다.
