Abstract
A disclosed system, method and computer readable storage medium is provided to receive an input video comprising a plurality of video frames, each of which has a plurality of input pixels. Each input pixel is of n-bit depth (e.g., 8-bit depth). The method optionally increases the bitdepth of each input pixel by a predetermined factor (e.g., 4-bit factor). The method further compresses and reconstructs each pixels of the input video. The method further compresses and reconstructs each pixel of intermediate frame buffers stored in a decoder frame buffer. The method calculates an adaptive offset for each block (e.g., of size of 4×4) of reconstructed pixel values of the intermediate frame buffers. Furthermore, the method can compute two-sub-block offset values and uses them to compute an optimized adaptive offset to be applied to each pixel within the corresponding sub-block.
