Abstract
Encoding digital video frames in intra-prediction mode by selecting reference data locations for blocks adjacent a current block identified by a writing pointer using reading pointer offsets added to the writing pointer. The reading pointer offsets include separate offsets for even and odd macro block rows of the frame that when added to the writing pointer create writing pointers to reference data for blocks located to the left, to the left and above, and above the current block. The offsets are pre-calculated and preloaded in an offset buffer, considering the number of macro blocks in a row of the frame, the number of blocks in a macro block, the number of reference data samples of a block, and the number of adjacent blocks reference data to be read. The concept can be applied to various video processing luminance components, chrominance components, and processing standards.
