Abstract :
We propose efficient video coding algorithms that lead to a significant speed improvement in low bit rate video coding, while maintaining high video reproduction quality. We also map some of the SIMD structured components of video coding onto Intel´s MMX architecture. The developed algorithms are implemented using our public-domain H.263+ encoder/decoder software.
