摘要： This disclosure describes content-adaptive coding and modulation techniques. In particular, this disclosure describes techniques in which both a multimedia coding mode and a physical layer modulation scheme are adaptively selected based on content of a multimedia sequence. When the content changes such that either the coding or the modulation scheme can be improved, the coding and/or modulation may be changed to better optimize to the changed content. In one aspect, this disclosure provides a method of processing multimedia data, the method comprising selecting a multimedia coding mode for an encoder to encode the multimedia data and a physical layer modulation scheme for transmission of the multimedia data based on content of the multimedia data.

摘要： This disclosure describes techniques for improving mode selection decisions during the encoding of macroblocks (or other blocks) of multimedia frames of a multimedia sequence. During motion estimation, the encoding modes for macroblocks can be determined so that a desirable encoding rate and acceptable levels of distortion (i.e., acceptable rate-distortion) can be achieved. The techniques may include selecting a set of multimedia coding modes between at least two sets of possible multimedia coding modes for a macroblock of a multimedia frame based on a detail metric associated with the macroblock and mode information associated with neighboring blocks to the macroblock.

摘要： In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.
