Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Context-adaptive binary arithmetic coding (CABAC) is a form of entropy coding used in H.264/MPEG-4 AVC video encoding. It is a lossless compression technique. It is notable for providing much better compression than most other encoding algorithms used in video encoding, and is one of the primary advantages of the H.264/AVC encoding scheme. CABAC is only supported in Main and higher profiles and requires a large amount of processing to decode compared to similar algorithms. It is also difficult to parallelize and vectorize. As a result, Context-adaptive variable-length coding (CAVLC), a lower efficiency entropy encoding scheme, is used to increase performance on slower playback devices.
