Patent Document ID: 8212696
Application ID: 12893132

Base Claim:
1. A context-based adaptive binary arithmetic coding (CABAC) decoding device, comprising: a context memory address calculator arranged to calculate an address identifying a memory location in a context model memory for storage of a context model in a next cycle; a mixed context memory to store the context model of the context memory address calculator; a two-bin context adaptive binary arithmetic decoder arranged to output a plurality of parameters for updating a range and an offset of the context model based on the context model of the mixed context memory, and to determine a plurality of bins; and a binary syntax element comparator arranged to determine whether a current binary sequence corresponds to a value of syntax elements, based on the bins so as to select a correct memory address.

Claim 3:
3. The context-based adaptive binary arithmetic coding (CABAC) decoding device as claimed in claim 1 , wherein the mixed context memory includes a static random access memory from which a first context model is read and a register from which two second context models are read.
