Abstract: A method of de-blocking filtering a processed video is provided. The processed video includes a plurality of blocks and each block includes a plurality of sub-blocks. A current block of the plurality of blocks includes vertical edges and horizontal edges. The processed video further includes a set of control parameters and reconstructed pixels corresponding to the current block. A boundary strength index is estimated at the vertical edges and at the horizontal edges of the current block. The set of control parameters, the reconstructed pixels corresponding to the current block and partially filtered pixels corresponding to a set of adjacent sub-blocks are loaded. The vertical edges and the horizontal edges of the current block are filtered based on the boundary strength index and the set of control parameters such that a vertical edge of the current block is filtered before filtering at least one horizontal edge of the current block.

Abstract: A method for sample adaptive offset (SAO) filtering of largest coding units (LCUs) of a video frame in an SAO component is provided that includes receiving, by the SAO component, an indication that deblocked pixel blocks of an LCU are available, and applying SAO filtering, by the SAO component, to each pixel block of pixel blocks of an SAO processing area corresponding to the LCU responsive to the indication, wherein pixels of each pixel block of the SAO processing area are filtered in parallel.
