Abstract
An effective H.264/AVC CAVLC decoding method is disclosed. In accordance with the method a VLC code is classified into groups according to a correlation thereof, an arithmetic equation is defined for each of the groups, and a decoding is carried out according to the arithmetic equation in order to minimize a memory access by a table look-up and reduce a decoding time and a power consumption.
