摘要： Methods, systems and computer program products that may improve the efficiency of the video encoding process. Mode decision processing and bit stream packing may be performed in parallel for various frames in a sequence. This reduces the amount of idle time for both the mode decision processing logic and the bit stream packing logic, improving the overall efficiency of the video encoder.

摘要： Various embodiments are generally directed to an apparatus, method and other techniques for divide a frame comprising pixels into a number of macroblocks, each macroblock comprising a number of pixels within four macroblock boundaries. Various embodiments may also include creating at least two regions having a plurality of macroblocks by dividing the frame along macroblock boundaries and generating wave front groups based on the macroblocks in each region, each wave front group from each region comprising one or more macroblocks to process in parallel.

摘要： A method of pitch corrected speed control (PCSC) playback in which a decoder rate controller receives a desired playback speed from a PCSC controller and determines the number of decoded digital audio samples stored in a buffer. The rate controller then determines the required number of execution times of a parametric speech decoder based on the desired playback speed and the number of decoded samples stored in the buffer. The parametric speech decoder is then executed the determined number of times.
