Abstract
The present invention is related to video coding and decoding, in particular HEVC SCC that define a palette coding mode. In conventional palette modes, the block of levels built from the Coding Unit and from the palette is encoded using syntax elements, such as the “Pred mode” element, the optional “Level” element and the “Run” element defining the number of successive indexes of the block of indexes that are concerned by an operation defined by the “Pred mode” element and the optional “Level” element. In improved embodiments of the invention, the last “Run” element for the Coding Unit uses a particular up-to-end codeword, instead of a codeword associated with a defined number of successive indexes, in order to indicate to perform the operation for the indexes at all remaining block positions up to the end of the block of indexes, regardless the number of the remaining block positions, are concerned.
