METHOD AND DEVICE FOR IMAGE ENCODING/DECODING FOR TRANSMISSION OF COLOR SIGNAL COMPONENT PREDICTION IN SERVICE SIGNALS ACCORDING TO WHETHER PALETTE MODE IS APPLICABLE OR NOT, AND METHOD FOR BIT STREAM TRANSMISSION Russian patent published in 2023 - IPC H04N19/186 H04N19/157 

FIELD: image processing.

SUBSTANCE: invention is related to encoding/decoding images for transmission in service signals of prediction information of components of color signals. An image decoding method is proposed, which is carried out by means of image decoding equipment, and contains: determining the current block by splitting an image; identifying whether or not a palette mode is applied to the current block based on the palette mode flag obtained from the bitstream; obtaining palette mode encoding information of the current block from the bit stream based on the tree type of the current block and whether or not palette mode is applied to the current block; and obtaining chroma component prediction information of the current block from the bitstream based on a palette mode not applied to the current block.

EFFECT: increase of efficiency of encoding/decoding by transmitting prediction information of color signal components in service signals.
