Abstract :
In this paper, several techniques for real-time realization of an MPEG-4 video decoder software is presented. The structure of the decoder is also discussed. Our methods improve the processing of three computationally intensive modules, context-based arithmetic decoding, padding, and variable length decoding. The decoding speed of our developed software is a few times faster than the existing MPEG-4 reference software
