✦ Synopsis

This article describes the architecture of a digital signal processor (DSP)-based real-time video communications system and the implementation of the ITU-T H.263 video coding standard on the system. The system incorporates a Texas Instruments TMS320C80 Multimedia Video Processor (MVP), a high-performance, single-chip multiprocessor-based DSP that is optimized for image and video operations. Our implementation of the ITU-T H.263 is optimized to make full use of the special features of the TMS320C80 MVP. The various related processing tasks have been efficiently distributed on the parallel processing elements within the TMS320C80 MVP.
