Abstract: Several methods and systems for reducing blocking artifacts are disclosed. In an embodiment, the method includes receiving a pair of adjacent blocks having an edge being positioned between the adjacent blocks. The pair of adjacent blocks is associated with one or more coding blocks. The one or more coding blocks comprise one or more coding information associated with the coding of the pair of adjacent blocks. The method also includes conducting a determination of whether the pair of adjacent blocks is coded in a skip-mode based on the one or more coding information. The edge is filtered based on the determination. Filtering the edge comprises disabling a de-blocking filtering of the edge based on a determination that the pair of adjacent blocks is coded in the skip-mode; and enabling the de-blocking filtering of the edge based on determination that the pair of adjacent blocks is not associated with the skip-mode.

Abstract: Deblocking filtering is provided in which an 8×8 filtering block covering eight sample vertical and horizontal boundary segments is divided into filtering sub-blocks that can be independently processed. To process the vertical boundary segment, the filtering block is divided into top and bottom 8×4 filtering sub-blocks, each covering a respective top and bottom half of the vertical boundary segment. To process the horizontal boundary segment, the filtering block is divided into left and right 4×8 filtering sub-blocks, each covering a respective left and right half of the horizontal boundary segment. The computation of the deviation d for a boundary segment in a filtering sub-block is performed using only samples from rows or columns in the filtering sub-block. Consequently, the filter on/off decisions and the weak/strong filtering decisions of the deblocking filtering are performed using samples contained within individual filtering blocks, thus allowing full parallel processing of the filtering blocks.

To process the vertical boundary segment, the filtering block is divided into top and bottom 8×4 filtering sub-blocks, each covering a respective top and bottom half of the vertical boundary segment. To process the horizontal boundary segment, the filtering block is divided into left and right 4×8 filtering sub-blocks, each covering a respective left and right half of the horizontal boundary segment. The computation of the deviation d for a boundary segment in a filtering sub-block is performed using only samples from rows or columns in the filtering sub-block. Consequently, the filter on/off decisions and the weak/strong filtering decisions of the deblocking filtering are performed using samples contained within individual filtering blocks, thus allowing full parallel processing of the filtering blocks.

Abstract: A method of multimedia data encoding and a multimedia data encoding device is provided. The method includes accessing a frame associated with the multimedia data, the frame including a plurality of rows of blocks, each of the plurality of rows including a plurality of blocks. The method also includes reconstructing a first selected block of a first selected row, during a first time slot of a pipeline and a first selected block of a second selected row, during a second time slot of the pipeline. In addition, the method includes determining a first intra prediction mode optimal for intra prediction of the first selected block of the second selected row, during the first time slot of the pipeline, and a second intra prediction mode optimal for intra prediction of a second selected block of the first selected row during the second time slot, based a previously reconstructed block.

Abstract: A method includes determining whether spatial intra prediction of pixels of a macroblock of a video frame is to be performed at a macroblock level or a sub-macroblock level. The method also includes suppressing a horizontal mode or a vertical mode of spatial intra prediction of pixels of the macroblock at the macroblock level or the sub-macroblock level based on the determination when spatial intra prediction of pixels of the immediate previous macroblock is at the sub-macroblock level. When the spatial intra prediction of the pixels of the macroblock is at the macroblock level, the horizontal mode or the vertical mode is suppressed for the entire macroblock. When the spatial intra prediction of the pixels of the macroblock is at the sub-macroblock level, the horizontal mode or the vertical mode is suppressed for a corresponding first row or a first column of blocks of pixels of the macroblock.
