Abstract
A method for decoding a video frame includes receiving a slice in a video decoder, identifying the slice as one of at least a first predicted slice and a second predicted slice, receiving information used to determine a context initialization method corresponding to the slice, and initializing, based on the received information, one of a first context initialization method and a second context initialization method associated with the slice, and decoding the video frame using the slice and one of the first context initialization method and the second context initialization method. The first context initialization method is a method for initializing a context associated with the first predicted slice and the second context initialization method is a method for initializing a context associated with the second predicted slice.
