Claim Text:
1. A method for decoding a video frame, the method comprising: (a) receiving a slice; (b) receiving a flag that is used in determining one of three initialization methods; and (c) initializing a Context-Adaptive Binary Arithmetic Coding (CABAC) context associated with a slice type; wherein in a case that the slice type indicates a B slice type and a value of the flag is equal to a first value, a CABAC context associated with the B slice type is initialized by a first initialization method of the three initialization methods, in a case that the slice type indicates the B slice type and the value of the flag is equal to a second value, the CABAC context associated with the B slice type is initialized by a second initialization method of the three initialization methods, wherein the second initialization method being used to initialize a CABAC context associated with a P slice type in a case that the slice type indicates the P slice type and the value of the flag is equal to the first value, and in a case that the slice type indicates an I slice type, a CABAC context associated with the I slice type is initialized by a third initialization method of the three initialization methods without using the flag.
