Abstract

The present invention relates to an arithmetic decoding system and apparatus based on the adaptive content. The system includes a control unit, a decoding unit and an interface unit. The control unit fills the 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 the syntax elements from the code stream data in the macro block, assembles the syntax elements and transmits them to the control unit. The interface unit transfers the interaction information between the decoding unit and the control unit. The present invention obtains syntax elements by the CABAC decoding through hardware so that the decoding efficiency is highly improved and the requirements for the video processing speed and the data processing capacity of the real-time and high definition applications are satisfied.
