Abstract
A decoding method is adapted to be implemented using a Context-based Adaptive Binary Arithmetic Coding (CABAC) decoding apparatus, and includes: initializing a plurality of context variables; storing the context variables; performing arithmetic decoding of a syntax element according to the context variables so as to output a decoded syntax element and an update signal; and updating at least one of the context variables according to the update signal. At least one of the context variables is pre-initialized in the initializing step before a bit stream ready.
