Patent ID: 6885707

Claim:
A system for receiving and processing MPEG data comprising; a digital timer for receiving a data channel containing an MPEG coded data stream; a decoding system including; a frequency converter module disposed to transform frequency coefficients in the MPEG ceded data stream to a spatial domain to obtain spatial domain data associated with the MPEG data, a subsampling module for subsampling the spatial domain data by a selected factor to generate subsampled spatial domain data, wherein subsampling the spatial domain data includes weighting color parameters of at least first and second spatial samples using at least first and second weighting factors, respectively and summing the weighted color parameters of the at least first and second spatial samples to generate a color parameter of a subsample that corresponds to the at least first and second spatial samples, and a motion vector module disposed to receive motion vector and reference image data in the MPEG coded data stream, and to process a reference frame and motion vector of the MPEG data to generate predicted frame data; a summer for adding the predicted frame data and the subsampled spatial domain data to generate first video images encoded in a reduced volume of video data; and a frame buffer disposed ta buffer frames of the first video images,
