METHOD AND DEVICE FOR BINDING TO CURRENT IMAGE FOR ENCODING VIDEO Russian patent published in 2019 - IPC H04N19/00 H03M7/30 

FIELD: data processing.

SUBSTANCE: invention relates to video encoding and decoding and is intended for an encoding system using a referenced to a current image (CPR). According to this method, the units of luminance and chromaticity of the current image are jointly encoded using the same structure of the coding cell (CU), if the CPR mode is selected for the luminance and chromaticity units. In other cases, if the luminance and chromaticity components are separated into luminance and chromaticity units separately using separate CU structures, luminance and chromaticity units are encoded or decoded using a coding mode selected from a coding mode group excluding the CPR mode. According to the other method, the units of brightness and chromaticity of the current image are coded separately using the other CU structure, if the CPR mode is selected for the luminance and chromaticity units. In another method, reconstructed reference data are disclosed for CPR mode with CU equal to PU.

EFFECT: encoding efficiency increase.
