  • Patent number: 9578334
    Abstract: In a video processing system, a method and system for generating a transform size syntax element for video decoding are provided. For high profile mode video decoding operations, the transform sizes may be selected based on the prediction macroblock type and the contents of the macroblock. A set of rules may be utilized to select from a 4.×.4 or an 8.×.8 transform size during the encoding operation. Dynamic selection of transform size may be performed on intra-predicted macroblocks, inter-predicted macroblocks, and/or direct mode inter-predicted macroblocks. The encoding operation may generate a transform size syntax element to indicate the transform size that may be used in reconstructing the encoded macroblock. The transform size syntax element may be transmitted to a decoder as part of the encoded video information bit stream.

  • Patent number: 7894530
    Abstract: In a video processing system, a method and system for dynamic selection of transform size in a video decoder based on signal content are provided. For high profile mode video decoding operations, inverse transform sizes may be selected from a 4×4 or an 8×8 inverse transform size based on a transform size syntax element generated by the encoding operation and transmitted as part of the encoded video information bit stream. A set of rules is defined for selecting the transform size based on a macroblock type and a size of the macroblock type of a received macroblock in a video decoder. Dynamic selection of transform size may be performed on intra-coded macroblocks, inter-coded macroblocks, and/or direct mode inter-coded macroblocks.
