Claim Text:
1. A non-transitory computer readable medium storing computer-readable instructions that, when executed by a processor of an apparatus, instructs the processor to perform a method for decoding a video frame, the method comprising: identifying whether a slice type is B-slice type; decoding information including: (i) first information indicating a number of second regions in a first region, and (ii) second information indicating an offset of an i-th second region from an (i−1)th second region in a bitstream, wherein the video frame includes one or more of the first region(s) and one or more of the second region(s); and initializing a Context-adaptive binary arithmetic coding (CABAC) context associated with the B-slice type using a flag for determining an initialization method, the initialization method indicating one of a first initialization method and a second initialization method; wherein in a case that the identified slice type is the B-slice type and a value of the flag is equal to a first value, the CABAC context associated with the B-slice type is initialized using the first initialization method as the initialization method, in a case that the identified slice type is the B-slice type and a value of the flag is equal to a second value, the CABAC context associated with the B-slice type is initialized using the second initialization method as the initialization method, the second initialization method differs from the first initialization method, and the second region(s) are a largest coding unit (LCU) row.
