RULES FOR INTRA-PICTURE PREDICTION MODES WHEN WAVEFRONT PARALLEL PROCESSING IS ENABLED Russian patent published in 2019 - IPC H04N19/436 H04N19/593 H04N19/11 

FIELD: computer equipment.

SUBSTANCE: invention relates to the computer equipment. Image encoding method used in a computer system in which an image is encoded with wavefront parallel processing (WPP) enabled, wherein the encoding generates encoded data, which includes, for prediction with internal blocking, a step at which one or more constraints compatible with WPP are forcibly activated, wherein one or more constraints includes a constraint that the value of horizontal shift from the reference area to the current area is less than or equal to the value of vertical shift from the current area to the reference area; and the encoded data are output as part of a bit stream.

EFFECT: encoding acceleration when using internal copy mode for the current image.
