Abstract: A method of reducing the memory required for decompression of a compressed frame by storing frame in a compressed format using DCT based techniques and decoders for implementing such a method are disclosed. The decoder is coupled to a memory where the frame can be stored. The decoder includes a decoder module having a parser, a block decoder module and a motion compensation engine. The decoder module is coupled to a DCT encoder module, which has an output coupled to the memory. The decoder also includes a stored DCT decoder module, which has an input coupled to the memory, a first output coupled to the motion compensation module and a second output that functions as an output of the decoder.
