Patent Document ID: 9628827
Application ID: 15244126

Base Claim:
1. A decoder for decoding a video from a data stream comprising syntax elements encoded therein, the decoder comprising: an entropy decoder configured to decode the syntax elements based on one or more of a plurality of contexts used in binary entropy decoding, wherein the entropy decoder is configured to initialize each of the plurality of contexts based on, for each context, a slope value and an offset value, wherein the slope value and the offset value are determined based on first and second four-bit parts of an 8-bit initialization value associated with the context; and a reconstructor configured to reconstruct the video based on the decoded syntax elements.

Claim 2:
2. The decoder according to claim 1 , wherein the data stream comprises encoded binarizations of the syntax elements; the entropy decoder is configured to decode the binarizations based on the binary entropy decoding; the decoder further comprises a desymbolizer configured to debinarize the binarizations of the syntax elements to obtain integer values of the syntax elements; and the reconstructor is configured to reconstruct the video based on the integer values of the syntax elements.
