Abstract: A de-blocking filter includes a reconstructed memory that is configured to store reconstructed pixels corresponding to a current macroblock of a video image to be filtered. The current macroblock includes a set of sub-blocks, each sub-block having horizontal edges and vertical edges. An internal pixel buffer in the de-blocking filter is configured to store pixels corresponding to the set of sub-blocks from the reconstructed memory, and to store partially filtered pixels corresponding to a set of partially filtered macroblocks. An edge order controller in the de-blocking filter is configured to load the pixels corresponding to the set of sub-blocks into a filter engine from the internal pixel buffer, to filter the set of sub-blocks, such that, at least one horizontal edge is filtered before filtering all vertical edges of the set of sub-blocks.

Abstract translation: 解块滤波器包括重建存储器，其被配置为存储与要滤波的视频图像的当前宏块对应的重构像素。 当前宏块包括一组子块，每个子块具有水平边和垂直边。 去块滤波器中的内部像素缓冲器被配置为存储对应于来自重建存储器的子块集合的像素，并且存储对应于一组部分滤波的宏块的部分滤波的像素。 解块滤波器中的边缘顺序控制器被配置为将与子集合对应的像素从内部像素缓冲器加载到滤波器引擎中，以过滤子块集合，使得至少一个水平 在对该子块集合的所有垂直边进行滤波之前对边进行滤波。
