Decoding system and method based on context-based adaptive binary arithmetic coding

摘要

A CABAC decoding system and a method are disclosed. The system includes at least a decoding unit group. Each decoding unit group includes N decoding units connected with each other. The M^th decoding unit receives parameter information for decoding bins and bit streams to be decoded, decodes the bins of the bit streams to be decoded, obtains the decoding result of the current decoding unit bin, and sends the updated parameter information to the (M+1)^th decoding unit and an output unit. The present invention achieves high decoding rate, and keeps a reasonable cost of hardware resource. So, the present invention provides a high efficient and reasonable decoding solution.
