Abstract: 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.

Abstract: 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.

Abstract: Systems and methods for intra prediction video coding are described herein. In one aspect, an apparatus includes a processor and a memory. The processor divides a video block into a plurality of video sub-blocks having a first size. The video block includes video units and has an intra prediction mode, and each video sub-block of the plurality of video sub-blocks includes at least a non-zero integer number of video units of the video block. The processor further determines prediction variables for a first video sub-block of the plurality of video sub-blocks based on the intra prediction mode of the video block and determines a predicted video unit for each video unit of the first video sub-block based on the intra prediction mode of the video block and the prediction variables for the first video sub-block. The memory stores the predicted video units.
