Abstract: An MPEG video resolution reduction system includes an MPEG decoder, a down-sampler, and a partial MPEG re-encoder. The MPEG decoder decodes an input resolution MPEG stream to an input resolution baseband, and determines coding information from decoding the input resolution MPEG stream. The down-sampler down-samples the input resolution baseband to a reduced resolution baseband. The partial MPEG re-encoder uses the coding information to encode the reduced resolution baseband to a reduced resolution MPEG stream.

Abstract: The present invention discloses a system and method for providing a rate control to an encoder, e.g., a H.264/MPEG-4 AVC compliant encoder. Specifically, the rate control method computes a target rate for a segment, where the segment comprises at least one slice of macroblocks. In turn, a target rate is computed for the at least one slice of macroblocks from the target rate for the segment. In turn, a quantization parameter (QPj) is computed for a macroblock (j) of the macroblocks from the target rate for the at least one slice. Finally, the macroblock (j) is encoded in accordance with said quantization parameter (QPj).

Abstract: A video coding system includes a prediction module configured to perform multi-reference picture sub-pixel motion estimation. Reference pictures are selected for the sub-pixel motion estimation based on full-pixel motion estimation. A cost function is used to select the reference pictures from one or more groups of reference pictures for a block in a macroblock. The cost is based on full-pixel motion estimation errors and a predicted motion vector for the block. The selected reference pictures are used for sub-pixel motion estimation to get the final motion vector for each block.
