摘要： 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. For example, the rate control method computes a target group of pictures (GOP) rate for a GOP of the input image sequence. The rate control method then computes a target rate per picture from the target GOP rate. In one embodiment, the target rate comprises at least one of: a frame picture target rate and a field picture target rate, wherein the field picture target rate is computed in accordance with two complexity measures for two predicted (P) fields, one complexity measure for one intra (I) field and one complexity measure for one bi-predicted (B) field.

摘要： A method for determining quantization parameters is provided. The method includes determining one or more first units of video content in a grouping of units and analyzing whether the one or more first units of video content within a region in the grouping of units have coefficients for the video content that are zero. The method then determines whether a quantization parameter for one or more second units of video content different from the one or more first units of video content is to be used to derive the quantization parameter for the one or more first units of video content. When the quantization parameter for the one or more second units of video content is to be used, the quantization parameter for the one or more first units of video content is derived from the quantization parameter for the one or more second units of video content.

摘要： 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.
