摘要： Methods and systems for efficient searching of candidate blocks for inter-coding and/or intra coding are provided. In one innovative aspect, an apparatus for performing motion estimation is provided. The apparatus includes a processor configured to identify a number of candidate blocks of a frame of video data to be searched, at least one candidate block corresponding to a block of another frame of the video data. The processor is further configured to select one or more of the candidate blocks to search based on a distance between the candidate blocks. The processor is also configured to select a method for searching the selected candidate blocks based on a format of the video data. The processor is also configured to estimate the motion for the block of the another frame based on the selected method and the selected candidate blocks.

摘要： Methods and systems for performing at least one of video encoding and video decoding are disclosed. In one implementation, the system includes a controller configured to determine a video standard associated with a portion of the video data, each portion of the video data associated with one of a plurality of video standards. The controller is further configured to provide a set of the filter parameters which are associated with a video standard to be used for at least one of the video encoding and decoding and at least one filter configured to filter at least one reference pixel received from the reference pixel memory based, at least in part, on the provided set of filter parameters.

摘要： Systems and methods for interleaving video sub-blocks in video coding are described herein. In one aspect, an apparatus includes a memory and a video coder. The memory stores a first video block and a second video block. The first video block and the second video block include sub-blocks. The video coder processes a first sub-block of the first video block according to a first process and a second process, and processes a second sub-block of the first video block according to the first process and the second process after processing the first sub-block of the first video block according to the first process and the second process. Further, the video coder processes a first sub-block of the second video block according to the first process before processing the second sub-block of the first video block according to the first process.
