Abstract
A method for video decoding ensuring a consistent interaction of some signaling tools with some encoding tools. The method is particularly advantageous when a container intended to provide parameters required for applying an encoding tool is missing while the encoding tool is activated for a given block. Examples include obtaining a first information indicating if a container of a first type providing at least one coding parameter is absent from the bitstream; checking a value of a first syntax element indicating if a coding tool using said at least one coding parameter is activated for a current block of samples of an image of the video sequence; and, adapting a decoding of the current block in case of absence of the container when the second syntax element indicates an activation of the coding tool.
