Abstract

본 발명은 동영상 부호화장치에서의 데이타 압축비를 높임으로서 전송화질을 개선하기 위한 것으로, 스의칭수단을 통해 입력되는 부호화된 영상신호를 가변길이 부호화한는 동영상 부호화장치의 가변길이 부호화장치에 있어서, 스위칭수단의 일측 가변접점에 접속되고, 인터모드 부호화시의 변환계수를 가변길이 부호화하기 위한 제1부호화부와; 스위칭수단의 타측 가변접점에 접속되고, 인트라모드 부호화시의 변환계수를 가변길이 부호화하기 위한 제2부호화부를 구비함으로서, 동영상 부호화장치에서의 데이타 압축효율이 개선되어 고화질의 영상신호를 얻을 수 있는 것이다.The present invention is to improve the transmission quality by increasing the data compression ratio in a video encoding apparatus. In the variable length encoding apparatus of a video encoding apparatus, variable length encoding of an encoded video signal input through a switching means is provided. A first encoder connected to one side of the variable contact point for variable-length encoding the transform coefficient during inter-mode encoding; It is connected to the other variable contact point of the switching means and includes a second encoder for variable length encoding the transform coefficient in the intra mode encoding, thereby improving the data compression efficiency in the video encoding apparatus and obtaining a high quality video signal. .
