Context-Adaptive Binary Arithmetic Coding With Fixed-Length Codewords [PDF]
IEEE Transactions on Multimedia, 2015 Context-adaptive binary arithmetic coding is a widespread technique in the field of image and video coding. Most state-of-the-art arithmetic coders produce a (long) codeword of a priori unknown length. Its generation requires a renormalization procedure to permit progressive processing.
