Claims (2)
- 통신채널을 통해 전송되는 비디오 신호를 수신하여 디코더 측에 인가하는 비디오 데이타 수신버퍼에 있어서, 인가받은 직렬 상태의 프레임 단위 비디오 신호를 병렬상태의 데이타로 변환하여 수신버퍼 측에 출력하는 직렬/병렬 변환기와; 상기 통신 채널을 통해 전송되어 인가되는 프레임 단위의 비디오 신호에서 프레임의 헤더에 포함되어 있는 화상시작정보(PSC)를 검출함으로써 유효한 프레임의 비디오 신호를 검출하여 상기 직렬/병렬 변환기를 통해 상기 수신버퍼 측에 출력하여 저장케 하되, 상기 수신버퍼에 저장되어 있는 유효한 프레임의 비디오 신호를 카운트하는 유효 데이타 검출부와; 상기 유효 데이타 검출부의 카운트 정보에 의거하여 상기 수신버퍼의 데이타 저장상태를 연속적으로 감시하며, 상기 수신버퍼를 제어하여 프레임 단위의 비디오 신호를 상기 수신버퍼에 저장시키거나 상기 수신버퍼에 저장되어 있는 프레임 단위의 비디오 신호를 출력시키는 버퍼 제어부와; 상기 수신버퍼로 부터 병렬상태로 출력된 프레임 단위의 비디오 신호를 직렬상태로 변환하여 프레임 동기신호(FS)에 따라 디코더 측에 출력하는 병렬/직렬 변환기를 구비하는 것을 특징으로 하는 비디오 데이타 수신버퍼의 제어장치.
- 제1항에 있어서, 상기 유효 데이타 검출부는, 상기 화상시작정보(PSC)가 포함되어 있는 유효한 프레임의 비디오 신호가 검출되어 상기 수신버퍼에 저장되면 카운터값을 증가시키고, 상기 수신버퍼로부터 프레임의 비디오 신호가 인출되어 디코드 측에 출력되면 카운터값을 감소시키는 감 가산 레지스터를 구비하는 것을 특징으로 하는 비디오 데이타 수신버퍼의 제어장치.
