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： The invention concerns a method and a device for processing a current pixel block of an image using a palette prediction mode according to HEVC RExt. The mode uses a current palette to build a predictor block of indexes to predict the current pixel block. The current palette comprises entries associating entry indexes with pixel values. The method comprises predicting the current palette from entries of two or more palettes that are palettes previously used to process blocks of pixels. A palette predictor may be used that is built from the two or more palettes, preferably from the last used palette for a coding unit in the current coding entity and from the previously used palette for which a flag bitmap indicates whether or not its elements have been copied into the last used palette. Accordingly, the coding of the palette mode is improved.

摘要： The present invention is related to video coding and decoding, in particular HEVC RExt that define a palette coding mode dedicated to the coding of screen contents. In improved palette coding modes according to the invention, when building a palette, each time a new pixel is added to the class a palette entry defines, the palette entry is modified to take the means value of the pixels belonging to such class. In other improved palette coding modes, a built palette is post-processed to substitute a palette entry with a close entry of a palette predictor PRED. In yet other embodiments, palette coding modes having different threshold values to drive the building of their respective palettes are successively tested to use the best one in terms of rate-distortion criterion.
