Patent ID: 8711901

Claim:
A video processing system including a video processing device having an encoding mode where the video processing device encodes an input signal and a decoding mode where the video processing device decodes the input signal, the video processing device comprising: a motion search module, that generates a motion search motion vector for each macroblock of a plurality of macroblocks; a motion refinement module, coupled to the motion search module, that generates a refined motion vector for each macroblock of the plurality of macroblocks, based on the motion search motion vector; an intra-prediction module that generates a best intra prediction mode for each macroblock of the plurality of macroblocks; a mode decision module, coupled to the motion refinement module, and the intra-prediction module, that determines a final motion vector for each macroblock of the plurality of macroblocks based on costs associated with the refined motion vector, and the best intra prediction mode; a reconstruction module, coupled to the mode decision module, that generates residual pixel values corresponding to the final motion vector for each macroblock of the plurality of macroblocks when the video processing device is in the encoding mode and that generates unfiltered reconstructed frames when the video processing device is in the decoding mode and also when the video processing device is in the encoding mode; and a transform and quantization module, coupled to the reconstruction module, that transforms and quantizes the residual pixel values when the video processing device is in the encoding mode and that forms residual pixel values by inverse transforming and dequantization when the video processing device is in the decoding mode and also when the video processing device is in the encoding mode; wherein the motion search module, the motion refinement module, the intra-prediction module and the mode decision module are each implemented via separate ones of a plurality of function specific hardware engines and wherein at least one of the motion search module, the motion refinement module, the intra-prediction module, and the mode decision module, operates when the video processing device is in the encoding mode and also when the video processing device is in the decoding mode.
