10Mb/s의 전송률을 갖는 AMBTC를 이용한 영상부호기/부호기의 실시간 구현

A Real Time Implementation of Picture Coder/Decoder Using AMBTC at the Data Rate of 10Mb/s

This paper describes an implementation of the absolute moment block truncation coding(AMBTC) in real time for the moving picture data compression. We have realized a system composed of the encoder and decoder, and operated it using an NTSC TV signal. The encoder consists of a 4-1line buffer memory and a data processing block. Besides, there are signal conditioner and a control signal generator. Experimental results show that the quality of the processed image with a data rate of 10Mb/s is slightly degraded, but not objectionable, comparing data rate of 80Mb/s.
