Abstract[English]
The invention relates to a method for encoding a signal comprising at least one block of samples to be encoded, the method implementing the following steps in order to encode (10) at least one of the blocks, represented by a set of syntax elements, referred to as current block: - if at least two syntax elements of the set have a different value: • assigning (111) a first value to a first encoding indicator associated with the current block, and • encoding (112) the value of the at least two syntax elements of the set; - otherwise: • assigning (113) a second value, different from the first value, to the first encoding indicator, and • encoding (114) the value of a first syntax element of the set; and - encoding (12) the value of the first encoding indicator associated with the current block.[French]
L'invention concerne un procédé de codage d'un signal comprenant au moins un bloc d'échantillons à coder, mettant en œuvre les étapes suivantes, pour le codage (10) d'au moins un desdits blocs, représenté par un ensemble d'éléments de syntaxe, dit bloc courant : - si au moins deux éléments de syntaxe dudit ensemble portent une valeur différente : • affectation (111) d'une première valeur à un premier indicateur de codage associé audit bloc courant, • codage (112) de la valeur desdits au moins deux éléments de syntaxe dudit ensemble, - sinon : • affectation (113) d'une deuxième valeur, distincte de ladite première valeur, audit premier indicateur de codage, • codage (114) de la valeur d'un premier élément de syntaxe dudit ensemble, - codage (12) de la valeur dudit premier indicateur de codage associé audit bloc courant.
