<p>In one example, an apparatus for context adaptive entropy coding a video unit comprises a coder configured to code a syntax element, wherein a first value of the syntax element indicates that one or more of a plurality of context states are initialized using an adaptive initialization mode for the video unit, and a second value of the syntax element indicates that each of the plurality of context states is initialized using a default initialization mode for the video unit. In some examples, when the syntax element has the first value, the coder is further configured to code a map that indicates which of the context states are initialized using the adaptive initialization mode, and to further code either an initial state value for those contexts, or information from which the initial state values of those adaptively initialized context may be derived.</p> |
