ABSTRACT:
Data is discrete cosine transformed and streamed to a processor where quantized and inverse quantized blocks are generated. A second streaming data connection streams the inverse quantized blocks to an inverse discrete cosine transform block to generate reconstructed prediction error macroblocks. An addition circuit adds each reconstructed prediction error macroblock and its corresponding predictor macroblock to generate a respective reconstructed macroblock. The quantized macroblocks are zig-zag scanned, run level coded and variable length coded to generate and encoded bitstream.
