Abstract
본 발명은 동영상 부호화장치에서의 데이타 압축비를 증진시켜 전송화질을 개선하기 위한 것으로, 스위칭 수단을 통해 입력되는 부호화된 영상신호를 가변길이 부호화하는 동영상 부호화장치의 가변길이 부호화장치에 있어서, 영상신호를 입력모드에 의거하여 스위칭수단을 통해 적응적으로 가변길이 부호화하기 위해 적어도 두개의 가변길이 부호화수단을 구비한 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 for variable length encoding the encoded video signal input through a switching means, At least two variable length encoding means are provided for adaptively variable length encoding through the switching means based on the input mode.
