This paper gives a description of our real-time software MPEG-4 video decoder. The performance of the decoder and the fast algorithms used for real-time decoding are discussed. Our techniques used to speed up four computationally intensive modules, inverse discrete cosine transform, context-based arithmetic decoding, padding, and variable length decoding, are also presented in this paper. Our decoding speed is improved so that software real-time video decoding is possible.
