摘要： A method for determining encoding parameters for encoding indexes of a block of indexes used for encoding a coding unit of an image according to a palette, each index being related to one of the pixels forming the coding unit, the palette comprising a set of indexes associated to pixel values. The method comprises: - generating each index of the block of indexes related to the coding unit from the palette based on corresponding encoding parameters, and - if indexes of the block of indexes cannot be generated from the palette for at least one pixels of the coding unit, generating index values corresponding to escape values for replacing said indexes of the block of indexes which cannot be generated, wherein encoding parameters corresponding to an index are determined according to the spatial neighbourhood of said pixel regarding to an encoding order.

摘要： A video signal has at least a first signal component corresponding to a first color, and a second signal component, associated with the first signal component and corresponding to a second color. Each signal component is divided into blocks, and each block has one or more encodable units. The encoding of at least one encodable unit of the second signal component is switchable between first and second modes. A method of encoding the signal comprises excluding,for at least one encodable unit of the second signal component, use of the second mode for the encoding of the second- signal-component encodable unit concerned when at least one predetermined condition is satisfied relating to an encoded block or encodable unit of the first signal component that corresponds to the second-signal-component encodable unit concerned.

摘要： For an image portion to encode an initial set of motion information predictors is obtained (S502). It is tested (S512) whether the number (N) of motion information predictors in the initial set is lower than a target number (Nmax) and, if so, one or more motion information predictors are added(S516) to the initial set to generate a set of motion information predictors having controlled diversity. The motion information predictors of the initial set are actual motion information predictors, having motion vectors obtained from image portions of the image being encoded or of a reference image, and potential motion information predictors for addition include one or more further such actual motion information predictors and also include one or more virtual motion information predictors not having motion vectors obtained from image portions of said image being encoded or of a reference image. A motion information predictor for the image portion to encode is selected from the generated set of motion information predictors.

摘要： For an image portion to decode an initial set of motion information predictors is obtained (S502). It is tested (S512) whether the number (N) of motion information predictors in the initial set is lower than a target number (Nmax) and, if so, one or more motion information predictors are added (S516) to the initial set to generate a set of motion information predictors. The motion information predictors of the initial set are actual motion information predictors, having motion vectors obtained from image portions of the image being encoded or of a reference image, and potential motion information predictors for addition include one or more further such actual motion information predictors and also include one or more virtual motion information predictors not having motion vectors obtained from image portions of said image being encoded or of a reference image. A motion information predictor for the image portion to decode is selected from the generated set of motion information predictors.
