Paper Abstract

Adaptive quantization and rate-control are key components in the performance of video coding schemes. Within the framework of ongoing second phase of Motion Picture Experts Group (MPEG-2), various improvements in adaptive quantization and rate control concepts developed for MPEG-1 based coding are possible. In this paper, we first review the adaptive quantization schemes developed so far for MPEG based coding. We then analyze performance of one such scheme and compare its behavior with that expected from a good adaptive quantization scheme. Next, we propose several modifications that have the potential for substantially improving the performance of this scheme.
