ABSTRACT:
Given compressed video which supports the coding of interlaced and noninterlaced frames through DCT and motion compensation, shared information is used in a macroblock for efficient conversion of inter-coded blocks to DCT intra-coded blocks. The shared information is also used to efficiently construct spatially reduced images without decompression.
