Performance analysis of Intel MMX technology for an H.263 video H.263 video encoder

2. ~RODUCTION The htemationd Telecommunication Union, Telecommunication Standardisation Sector ~-~, has specified the first version of the H263 standard for video coding for low bit rate communication enabfing compression of video sequences to bit rates below @ kbps. The standard specifies a hybrid coding method containing discrete cosine transform @~ intra ties, and motion compznsatd and Da transformed inter frames. Applications for which tie standard is suitable include \<deo phone applications in the current Pubfic Switched Telephone Network &S~, and in future mobfie networks with data rates similar to the data rates of PS~. An H.263 encoder is one component of a video phone application.
