Abstract:
A decoder includes an entropy decoder configured to derive a number of bins of the binarizations from the data stream using binary entropy decoding by selecting a context among different contexts and updating probability states associated with the different contexts, dependent on previously decoded portions of the data stream; a desymbolizer configured to debinarize the binarizations of the syntax elements to obtain integer values of the syntax elements; a reconstructor configured to reconstruct the video based on the integer values of the syntax elements using a quantization parameter, wherein the entropy decoder is configured to distinguish between 126 probability states and to initialize the probability states associated with the different contexts according to a linear equation of the quantization parameter, wherein the entropy decoder is configured to, for each of the different contexts, derive a slope and an offset of the linear equation from first and second four bit parts of a respective 8 bit initialization value.

Claim (Index 14):
An encoder for encoding a video into a data stream, comprising:\n an entropy encoder configured to encode syntax elements related to the video into the data stream based on one or more of a plurality of contexts used in binary entropy encoding, wherein the entropy encoder is configured to:\n initialize a state variable and a value variable of at least one of the plurality of contexts based on a slope value of an initialization equation and an offset value of the initialization equation, and \n update a probability state associated with the at least one of the plurality of contexts in accordance with a previously-decoded portion of the data stream, and \n wherein the slope and offset values are derived based on first and second four-bit parts of an 8-bit initialization value associated with the at least one context.
