WebContext-adaptive binary arithmetic coding ( CABAC) is a form of entropy encoding used in the H.264/MPEG-4 AVC [1] [2] and High Efficiency Video Coding (HEVC) standards. It is … WebMar 24, 2010 · The following code implements binary addition without actually doing any arithmetic, binary or otherwise. The actual "addition" is done by lookupTable, and everything else is straight-up string manipulation.I wrote it with the intention of making it as instructive as possible, emphasizing the process instead of efficiency.
