Abstract

본 발명은 허프만 부호화를 이용하여 부호화하기에 적합한 부호화기에 관한 것으로, 종래에는 고정길이 부호화부가 양자화부의 양자화에 따른 몫과 나머지 중에서 나머지를 인가받아 고정길이 부호화하기 때문에 전체 비트 율이 증가하며, 구성시 롬 크기가 증가하여 전체 크기가 증가해서 실제로 구현하기가 어려웠으나, 본 발명에서는 우선적으로 양자화된 영상신호에 따른 몫과 나머지 중에서 몫을 가변길이 부호화하고, 나머지는 다시 양자화하여 몫을 가변길이 부호화함으로써 전체 비트 율이 작아지며, 두번의 양자화시 동일한 부호책을 사용하기 때문에 롬의 크기를 줄일 수 있어 전체 크기가 작아지므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to an encoder suitable for encoding using Huffman coding. Conventionally, since the fixed-length encoder receives fixed-length encoding by applying the remainder of the quantization part and the remainder of the quantization, the overall bit rate is increased. Since the ROM size is increased and the total size is increased, it is difficult to actually implement the present invention. The overall bit rate is reduced, and since the same codebook is used in two quantizations, the size of the ROM can be reduced, and thus the overall size is reduced, thereby improving the above-described drawbacks.
