摘要： This disclosure describes techniques associated with filtering of video data in a video encoding and/or decoding process. In accordance with this disclosure, filtering is applied at an encoder, and filter information is encoded in the bitstream to identify the filtering that was applied at the encoder. Different types of filtering may be applied based on an activity metric determined for the video data. Moreover, in accordance with this disclosure, the manner in which the filter information is encoded into the bitstream may be dependent on the activity metric. In particular, for a first range of the activity metric, one or more filters are encoded directly, and for a second range of the activity metric, one or more filters are predictively encoded.

摘要： Techniques are described for encoding and decoding digital video data using macroblocks that are larger than the macroblocks prescribed by conventional video encoding and decoding standards. For example, the techniques include encoding and decoding a video stream using macroblocks comprising greater than 16x16 pixels, for example, 64x64 pixels. Each macroblock may be partitioned into two or more partitions, and two or more of the partitions may be encoded using different modes. In one example, an apparatus includes a video encoder configured to receive a video block having a size of more than 16x16 pixels, partition the block into partitions, encode one of the partitions using a first encoding mode, encode another of the partitions using a second encoding mode different from the first encoding mode, and generate block-type syntax information that indicates the size of the block and identifies the partitions and the encoding modes used to encode the partitions.

摘要： In a video processing system, a method and system for applying transforms larger than 8x8 and non-rectangular transforms, and generating transform size syntax elements indicative of the transforms for video decoding are provided. The transform size syntax element may be generated by an encoder based on a prediction block size of a video block and the contents of the video block. Further, the transform size syntax element may be generated according to a set of rules to select from 4x4, 8x8, and larger transform sizes during an encoding process. A decoder may perform an inverse transform based on the transform size syntax element and the rules used by the encoder. The transform size syntax element may be transmitted to the decoder as part of the encoded video bitstream.

摘要： A video coding unit may be configured to encode or decode chrominance blocks of video data by reusing motion vectors for corresponding luminance blocks. A motion vector may have greater precision for chrominance blocks than luminance blocks, due to downsampling of chrominance blocks relative to corresponding luminance blocks. The video coding unit may interpolate values for a reference chrominance block by selecting interpolation filters based on the position of the pixel position pointed to by the motion vector. For example, a luminance motion vector may have one-quarter-pixel precision and a chrominance motion vector may have one-eighth-pixel precision. There may be interpolation filters associated with the quarter-pixel precisions. The video coding unit may use interpolation filters either corresponding to the pixel position or neighboring pixel positions to interpolate a value for the pixel position pointed to by the motion vector.
摘要翻译：视频编码单元可以被配置为通过重新使用对应的亮度块的运动矢量来对视频数据的色度块进行编码或解码。由于色度块相对于对应亮度块的下采样，运动矢量可能具有比亮度块更高的色度块精度。视频编码单元可以通过基于由运动矢量指向的像素位置的位置来选择内插滤波器来内插参考色度块的值。例如，亮度运动矢量可以具有四分之一像素精度，并且色度运动矢量可以具有八分之一像素的精度。可以存在与四分之一像素精度相关联的内插滤波器。视频编码单元可以使用对应于像素位置或相邻像素位置的插值滤波器来内插由运动矢量指向的像素位置的值。

摘要： A video coder may utilize large macroblocks having more than 16x16 pixels. Syntax for the large macroblocks may define whether a bitstream includes large macroblocks, such as superblocks having 64x64 pixels or bigblocks having 32x32 pixels. The syntax may be included in a slice header or a sequence parameter set. The large macroblocks may also be encoded according to a large macroblock syntax. The bitstream may further include syntax data that indicates a level value based on whether the bitstream includes any of the large macroblocks, for example, as a smallest-sized luminance prediction block. A decoder may use the level value to determine whether the decoder is capable of decoding the bitstream.
