Abstract:
A decoding method wherein a motion vector is associated with a block of pixels of a current image, wherein the image is subdivided into spatial subdivisions, wherein the block of pixels belongs to a current spatial subdivision and is to be predicted using an Intra Block Copy mode, using a predictor block of pixels of the image designated by the motion vector, and wherein the predictor block designated by the motion vector may belong to any one of previously decoded spatial subdivisions in the current image. Embodiments provide enhancements to the Intra Block Copy Mode of the HEVC standard.
