METHOD AND DEVICE FOR CODING VECTOR FOR CODING AND DECODING VIDEO Russian patent published in 2019 - IPC H04N19/105 H04N19/174 H04N19/436 H04N19/593 

FIELD: data processing.

SUBSTANCE: invention relates to the video encoding/decoding. Image encoding method in which an image contains a plurality of encoding tree blocks consisting of pixel blocks, each pixel block being encoded according to a mode of a plurality of modes, with one such mode being a mode, in which the block is coded based on the predictor block being the block of the current image, wherein the method comprises a step of determining a search area for the above mentioned mode as the region formed by available reconstructed blocks of a current encoding tree block, moreover, the availability of reconstructed blocks is determined on the basis of a scan order, and by the encoding tree blocks having the coordinates (X,Y), where Y≤Y₀ and (X-X₀)≤-(Y-Y₀), where X is a horizontal coordinate, Y is a vertical coordinate, the origin is in the upper left corner of an image, and (X₀,Y₀) are the coordinates of a current encoding tree block.

EFFECT: providing the possibility of performing parallel processing of wave fronts when encoding / decoding the image by determining the region from which the predictor block can be obtained.
