Abstract
A sequence of syntax elements is received. A symbol is determined for a syntax element of the sequence. The symbol is entropy coded using arithmetic coding based on a linear combination of a first probability model and a second probability model. The first probability model is updated using a first time-variant update rate to produce a first updated probability model for entropy coding a symbol for a subsequent syntax element of the sequence. The second probability model is updated using a second time-variant update rate, different from the first time-variant update rate, to produce a second updated probability model for entropy coding the symbol for the subsequent syntax element.
