All bins with binIdx greater than maxBinIdxCtx are parsed using the value of ctxIdx being assigned to binIdx equal to maxBinIdxCtx. All entries in Table 9-39 labelled with "na" correspond to values of binIdx that do not occur for the corresponding ctxIdxOffset. ctxIdx = 276 is assigned to the binIdx of mb_type indicating the PCM mode. For parsing the value of the corresponding bins from the bitstream, the arithmetic decoding process for decisions before termination as specified in clause 9.3.3.2.4 is applied. Rec.
