<p>PROBLEM TO BE SOLVED: To provide a processing method for bit modeling at a fast processing speed and a processing circuit using it. SOLUTION: A context and a decision changing with a state of a significant flag and a code bit of a bit being a processing object and a surrounding bit group are simultaneously generated according to the sig (significance propagation decoding) path, the context and the decision of the code bit are adopted only when a value of the processing object bit is '1', the significant flag is updated, the decision of the code bit are aborted when the value of the processing object bit is '0', the processing circuit for the bit modeling to update the processed flag is applied to bits circle 0 - circle 3 of the same group at the same time to process them in parallel independently of whether the value of the processing object bit is '1' or '0'.</p> |
