The H.263 video codec is an improved version of H.261 and is a constituent part of the H.324 video-conferencing codec suite. A system implementing a real-time ITU-T H.263 codec using a multi-processor DSP system has been configured by the authors. This paper describes the implementation scheme and additionally, some programming techniques to exploit the internal architecture of the multimedia video processor (MVP), and some strategies introduced to reduce the computational complexity whilst minimizing degradation of picture quality. The effects of these strategies have been tested and the codec performance are reported. The video codec is integrated with the G.723.1, H.223 and H.245 to form a full-duplex video-conferencing system
