Abstract
A decoder is disclosed for decoding MPEG video bitstreams encoded in any color space encoding format and outputting the decoded video bitstream to different sized windows. Both MPEG decompression and color space decoding and conversion are performed on the bitstreams within the same decoder. The disclosed decoder may be programmed to output the decoded video bitstream in any of three primary color space formats comprising YUV 4:2:0, YUV 4:2:2, and YUV 4:4:4. The decoder may also output the decoded bitstream to different sized windows using Discrete Cosine Transform (DCT) based image resizing.
