    摘要: This disclosure describes techniques for controlling a perceived quality of multimedia sequences to try to achieve a desired constant perceptual quality regardless of the content of the sequences. In particular, an encoding device may implement quality control techniques to associate a sequence segment with a content “class” based on the content of the segment, determine a perceptual quality metric of the sequence segment, and adjust at least one encoding parameter used to encode the segment is encoded such that for the perceptual quality of the sequence segment converges to the desired quality.

    摘要: This disclosure describes techniques for coding mode selection. In particular, an encoding device determines whether or not to code a block of pixels in a coding mode currently being considered for selection using information associated with at least one other coding mode with a different block partition. In one aspect, the encoding device uses information associated with at lest one coding mode that has block partitions that are sub-partitions of the block partitions of the coding mode currently being considered for selection. Additionally, the encoding device may use information associated with another coding mode that has the same block partitions as the coding mode currently being considered for selection or information associated with the coding mode currently being considered for selection.

    摘要: This disclosure describes techniques for coding mode selection using estimated coding costs. To provide high compression efficiency, for example, an encoding device may attempt to select a coding mode for coding blocks of pixels that codes the data of the blocks with high efficiency. To this end, the encoding device may perform coding mode selection based on estimates of coding cost for at least a portion of the possible modes. In accordance with the techniques described herein, the encoding device estimates the coding cost for the different modes without actually coding the blocks. In fact, in some aspects, the encoding module device may estimate the coding cost for the modes without quantizing the data of the block for each mode. In this manner, the coding cost estimation techniques of this disclosure reduce the amount of computationally intensive calculations needed to perform effective mode selection.
