Increasing the image size of a video sequence aggravates the memory bandwidth problem of a video coding system. Despite many embedded compression (EC) algorithms proposed to overcome this problem, no lossless EC algorithm able to handle high-definition (HD) size video sequences has been proposed thus far. In this paper, a lossless EC algorithm for HD video sequences and related hardware architecture...
With a rapid increase of image resolution in recent mobile video systems, the memory bandwidth and power consumption have surfaced as critical problems in video coding. Despite many embedded compression algorithms proposed to overcome these problems, no proper algorithms have yet been reported with high enough throughput and no quality loss. This paper first proposes a lossless embedded compression...
This paper introduces a low complexity VLSI hardware architecture for entropy coding with increased throughput, based on the study of the statistical properties of the context-based adaptive variable length coding (CAVLC) in AVC/H.264. These enhanced designs are due to the results of the statistical analyses, in which better symbol length prediction was achieved by breaking the recursive dependency...
