Patent ID: 7460041

Claim:
An arithmetic decoding system based on an adaptive content comprising a control unit, a decoding unit and an interface unit, wherein: the control unit fills code stream data into the decoding unit and configures and controls the decoding unit through the interface unit; the decoding unit performs a decoding for all syntax elements from the code stream data in a macro block, assembles the syntax elements and transmits them to the control unit; and the interface unit transfers interaction information between the decoding unit and the control unit, and the decoding unit comprising a decoding control unit, a decoding management unit and a decoding information management unit, wherein: the decoding control unit connects the decoding management unit and the decoding information management unit, receives a decoding control signal from the control unit and outputs the control signal of all the syntax elements in the code stream data to the decoding management unit and the decoding information management unit; the decoding management unit receives the decoding control signal from the decoding unit and in the macro block performs the decoding for all the syntax elements from the code stream data filled in the decoding unit; and the decoding information management unit stores the content probability models, selects a content probability model required by decoding each bin for the current syntax element according to the border block and macro block information and outputs the selected model to the decoding management unit for decoding.
