ABSTRACT

Abstract:- The intercommunications between the video devices using different standards are so much inconvenient, thus video codec supporting multiple standards are more useful and more attractive. In this brief, a low cost very large scale integration (VLSI) architecture is designed for multistandard inverse Discrete Cosine transform. It is used in multistandard decoder of MPEG-2, MPEG-4 ASP, and VC-1 .Two circuit share strategies, factor share (FS) an adder share (AS) are applied to the inverse transform architecture for saving its circuit resource. Pipelined stages are used in this Multistandard inverse transform to increase the operational speed.
