Abstract: A deblocking unit may include a buffer, an edge mask generator, and a deblocking filter. The buffer may store video data including blocks. The blocks may correspond to at least a portion of a macroblock. The edge mask generator may generate a particular edge mask that defines edges between blocks to be deblocked. The edge mask generator may include an edge mask memory to store a number edge masks and logic to choose the particular edge mask among the number of edge masks. The logic may choose based on a type of the video data in the buffer and a position offset of the macroblock. The deblocking filter may deblock edges between blocks of video data in the buffer based on the particular edge mask from the edge mask generator.

Abstract: According to some embodiments, systems, methods, and apparatus are provided to load video data into a hardware accelerator that is not adapted to receive interlace frames, wherein the video data comprises interlace frames, configure the hardware accelerator to receive interlace frames, and de-block the video data via the hardware accelerator.
