Abstract
The authors propose a fast, standard-compliant realization of the computationally expensive renormalization part of binary arithmetic coding in H.264/MPEG4 advanced video coding (AVC). Their technique allows to replace time-consuming, bitwise-operating input and output as well as bitwise carry-over handling in a conventional implementation with corresponding routines operating in units of multiple bits. Experimental results demonstrate that the authors' proposed method enables a considerable speed-up of both arithmetic encoding and decoding in the range of 24 to 53 % average run time.
