Abstract:
1. An encoding device for performing a Context-based Adaptive Binary Arithmetic Coding (CABAC) encoding process, the encoding device comprising: a binarization unit performing a first half of the CABAC encoding process by binarizing multivalued syntax elements to generate binary signals; a converting unit inserting a synchronous word indicating a starting position of an arithmetic-encoding operation into the generated binary signals to generate an intermediate bitstream, and storing the intermediate bitstream on an intermediate buffer; a detecting unit detecting the starting position of the arithmetic-encoding operation by detecting the synchronous word from the intermediate bitstream read from the intermediate buffer; and an arithmetic-encoding unit performing a second half of the CABAC encoding process by arithmetic-encoding the intermediate bitstream read from the intermediate buffer in accordance with the starting position detected by the detecting unit, wherein the generated binary signals are binary representations of values of the multivalued syntax elements, and are intermediate data of the CABAC encoding process.
