METHODS FOR INTERMEDIATE PREDICTION BASED ON PATTERN, BASED ON REDUCTION IN ENCODING AND DECODING DELAY Russian patent published in 2023 - IPC H04N19/105 H04N19/52 H04N19/109 

FIELD: video encoding/decoding.

SUBSTANCE: invention relates to the field of a video signal encoding and decoding. Methods for video encoding and decoding for reduction in delay in intermediate encoding based on a pattern are proposed. Methods include the current image and at least one reference image. For at least the current block in the current image, a corresponding predicted value is generated (for example, using a prediction with motion compensation) for each discrete count in an area of the pattern, adjacent to the current block. When predicted values are generated for each discrete count in the area of the pattern, a process is activated to determine a parameter of an intermediate prediction based on the pattern by means of predicted values in the area of the pattern and values of discrete counts in the reference image. This process can be activated without waiting for restored values of discrete counts in the area of the pattern. The intermediate prediction based on the pattern of the current block is then performed using the determined parameter of the intermediate prediction based on the pattern.

EFFECT: increase in the efficiency of encoding.
