Abstract : This project provides an integrated design approach of a portable video on demand system capable of delivering high quality image and video in a wireless communication environment. The research focuses on both the algorithm and circuit design techniques developed for implementing a low power video compression/decompression system at power levels that are two orders of magnitude below existing solutions. The three main technological challenges in realizing such a system are high compression efficiency for transmission bandwidth reduction, error resiliency to minimize the effects of channel error, and low power implementation for portability.
