Abstract
The present principles relate to a method and device for context-adaptive binary arithmetic coding a sequence of binary symbols representing a syntax element related to video data or a syntax element relative to a video data. The method comprises, for each binary symbol of the sequence of binary symbols:—obtaining () a context value from a context model defined for the binary symbol, said context value comprising bits representing the probability, called a first probability p, for the binary symbol to be equal to a binary value;—determining () a second probability p' by modifying said first probability p according to at least one previously coded binary symbol of the sequence of binary symbols;—arithmetic coding () the binary symbol based on said second probability p′; and—updating and storing () the first probability p of said context value
