Abstract :
Our present ability to work with video has been confined to a wired environment, requiring both the video encoder and decoder to be physically connected to a power supply and a wired communication link. This paper presents a portable video-on-demand system capable of delivering high-quality image and video data in a wireless environment. The discussion will focus on both the architectural and circuit design techniques developed for implementing a high-performance, error-resistant video compression/decompression system at power levels that are two orders of magnitude below existing solutions. This low-power video compression system not only provides a compression efficiency better than industry standards, but also embeds a high degree of error tolerance in the compression algorithm itself to guard against transmission errors often encountered in wireless communication
