Abstract

본 발명은 버퍼메모리를 PISO(Parallel-In-Serial-Out)로 구성하고 콘트롤러를 프로세서가 아닌 하드웨어로 구성하여 CCITT H.261에 근거하여 영상데이타의 흐름을 조절하고자 한 화상회의 비디오 시스템의 송신버퍼 장치에 관한 것으로서, 이러한 본 발명의 목적은 송신 비디오 데이타를 비디오 변조 디코딩하는 비디오 변조 코더(13)와, 상기 비디오변조코너(13)에서 출력되는 유효데이타 신호를 인가받아 송신버퍼 양자화기 선택신호를 출력하는 송신 버퍼 콘트롤러(22)와, 상기 송신버퍼콘트롤러(22)에서 출력된 양자화기 선택신호에 따라 상기 비디오 변조 코더(13)에서 얻어진 병렬 영상 데이타량 조절하고 직렬 영상데이타로 변환하여 채널을 전송하는 송신버퍼 메모리(21)을 구성함으로써 달성된다.According to the present invention, the buffer memory is configured as PISO (Parallel-In-Serial-Out) and the controller is configured as hardware instead of a processor to transmit video data based on CCITT H.261 to control the flow of video data. An object of the present invention is to provide a video modulation coder (13) for video modulation and decoding of transmission video data, and an effective data signal output from the video modulation corner (13) to receive a transmission buffer quantizer selection signal. The amount of parallel image data obtained by the video modulation coder 13 is adjusted according to the transmission buffer controller 22 and the quantizer selection signal output from the transmission buffer controller 22 and converted into serial image data to transmit a channel. Is achieved by configuring the transmission buffer memory 21.
