Encoding of motion video sequences for the MPEG environment using arithmetic coding
Abstract
In this paper, we describe a motion-compensated hybrid DCT/DPCM algorithm suitable for compressing motion video sequences at 1-1.5 Mbits/second. The algorithm is compatible with the currently emerging MPEG video compression standard with one exception: the entropy coding of the DCT coefficients, motion vector data and all side information is accomplished via arithmetic coding rather than Huffman coding. The algorithm can be made completely MPEG-compatible with the addition of an arithmetic-Huffman transcoder. Experimental results demonstrate the effect of the proposed changes on the compression efficiency.
