Abstract: A method and apparatus for determining neighborhood video attribute values for a frame of video data are disclosed. In one aspect, the method includes receiving coordinates for a current block location and a previous block location of the frame and generating a vector indicative of the displacement of the current block from the previous block via comparing the coordinates of the current block location to the coordinates of the previous block location. The method may also include updating the neighborhood video attribute values based at least in part on the generated vector and processing the frame based on the updated neighborhood video attribute values.

Abstract: Video pixel line buffers are widely used for data processing in video codecs. Video data may be packed into buffers configured to store a plurality of words, each word comprising a series of bits. The video data may be associated with two or more channels. In order to reduce realization costs, data blocks from two different channels may be packed from opposite sides of a word in the buffer in opposite directions. In some embodiments, data blocks from two or more physical channels may be mapped to two or more virtual channels, the virtual channels having balanced data block sizes. The data blocks associated with the virtual channels may then be packed to one or more buffers.

Abstract translation: 视频像素线缓冲器广泛用于视频编解码器中的数据处理。 视频数据可以被打包到被配置为存储多个字的缓冲器中，每个字包括一系列位。 视频数据可以与两个或更多个信道相关联。 为了降低实现成本，来自两个不同通道的数据块可以从相反方向的缓冲器中的字的相对侧打包。 在一些实施例中，来自两个或多个物理信道的数据块可以被映射到两个或更多个虚拟信道，虚拟信道具有平衡的数据块大小。 然后可以将与虚拟通道相关联的数据块打包到一个或多个缓冲器。
