Abstract
A data organization and access scheme for permitting easier location of a reference macroblock during motion compensation and for providing a video output system with output data. The frames are segmented into coding blocks comprising a small number of horizontally adjunct blocks compressed to a fixed length. Within each coding block, only two quantization strategies are employed so that the start and end position of any coding block is easily ascertained as well as the location of any individual block within the coding block.
