TRANSMISSION OF A MOTION VECTOR PREDICTOR IN SERVICE SIGNALS BASED ON PREDICTION SUBUNITS Russian patent published in 2022 - IPC H04N19/52 H04N19/70 

FIELD: video data processing.

SUBSTANCE: group of inventions relates to technology for encoding/decoding video data. Proposed is a method for decoding video data. The method includes a stage of receiving encoded video data. The motion flag is then syntactically analysed based on prediction subunits from the encoded video data. In response to determining that the motion flag based on prediction subunits is active, a list of motion prediction candidates at the level of prediction subunits is extracted. In response to determining the motion flag based on prediction subunits is not active, a list of motion prediction candidates at the level of prediction units is extracted. The list of motion prediction candidates at the level of prediction subunits or the list of motion prediction candidates at the level of prediction units is therein at least partially ordered based on motion prediction occurrences in the adjacent blocks. The encoded video data are also decoded using the selected motion vector predictor.

EFFECT: increase in the efficiency of decoding video data.
