Abstract: The invention is related to video coding and decoding. More precisely, the present invention is dedicated to a coding method investigated in the scope of screen content coding, called palette mode. It particularly concerns the encoding of level values based on the use of patterns to predict the level value in order to avoid their transmission. It has been devised to avoid the transmission of level value when the value may be predicted based on the neighbourhood of the pixel to encode. This neighbourhood is matched against memorized pattern so as to predict the level value due to the repetitive occurrence of these patterns. It proposes to save a pattern table in addition to the palette table. This pattern table is constructed symmetrically by the encoder and the decoder and allows to retrieve some predicted level value and to avoid their transmission.
