摘要： CABAC(Context Adaptive Binary Arithmetic Coding) decoding is provided to increase a decoding speed by simultaneously performing arithmetic decoding and context calculations. A system(100) includes a first block(102) and a second block(104). The first block includes a CABAC decoder and the second block includes a decoder having no CABAC. The first block has a first input(106) capable of receiving a signal, a second input(114) capable of receiving a signal, and an output(108) capable of outputting a signal. The second block has an input(110) capable of receiving the signal output from the output of the first block, a first output(112) capable of outputting a video signal, and a second output(113) capable of outputting the signal inputted to the second input of the first block.

摘要： PROBLEM TO BE SOLVED: To provide a context adaptive binary arithmetic decoding apparatus and method. SOLUTION: The present invention relates to an apparatus including a first circuit and a second circuit. The first circuit is configured to present a video signal and macroblock data in response to decoding one or more bins on a binary signal. The second circuit is configured to, in parallel, (i) generate the binary signal in response to a bitstream signal and initial context information and (ii) calculate subsequent context information.

摘要： A first circuit is configured to present a video signal and macroblock data in response to decoding one or more bins on a binary signal. A second circuit is configured to, in parallel, (i) generate the binary signal in response to a bitstream signal and an initial context information and (ii) calculate subsequent context information. This means that the CABAC decoder determines the context information to decode a bin before the bin is decoded, thereby speeding up processing. The decoder may find application in high definition (HD) video decoding.
