• MPEG data streams must be analyzed to identify each component so it can be processed accordingly.
• Motion vectors are extracted and used later once images are reconstructed from the other, variable length data, which is run through similar processing to JPEG decoding (entropy decoding, dequantization, inverse DCT) to yield image blocks.
• Frame reconstruction used previous frames, DCT decoding blocks, and motion vectors.
• Color space conversion yields a bitstream to drive an analog CRT.
