METHOD AND DEVICE FOR ENCODING/DECODING IMAGE SIGNAL Russian patent published in 2024 - IPC H04N19/109 H04N19/503 H04N19/119 

FIELD: data processing.

SUBSTANCE: invention relates to video processing, particularly to encoding or decoding video signals. Disclosed is an image decoding method used in a video decoder, which includes the following steps: determining whether to split the coding unit into a first prediction element and a second prediction element; determining the type of the coding unit section when it is determined that the coding unit is split; determining an index of a second merge candidate based on a comparison between the value of the second index information and the value of the first index information; obtaining first motion information with respect to a first prediction element and second motion information with respect to a second prediction element in the coding unit; and sampling the prediction count in the coding unit based on the first motion information and the second motion information.

EFFECT: high efficiency of decoding and obtaining a merge candidate using a table of information on movement between sections when encoding or decoding video signals.
