ENCODING METHOD AND VIDEO DECODING METHOD, APPARATUS THEREFOR, PROGRAMS THEREFOR, AS WELL AS DATA MEDIA STORING PROGRAMS Russian patent published in 2012 - IPC H04N7/32 H04N13/00 

FIELD: information technology.

SUBSTANCE: target frame of a reference vector and a reference vector from already encoded frames are selected; information for labelling each frame is encoded; the reference vector is set to indicate a region in the target frame of the reference vector relative the target encoding region; the reference vector is encoded; the corresponding regions are searched using image information of the target region of the reference vector belonging to the target frame of the reference vector and is indicated through the reference vector and the reference frame; the reference region in the reference frame is determined based on the search result; a predicted image is formed using reference frame image information corresponding to the reference region; and the difference information between the target encoding region information and the predicted image is encoded.

EFFECT: efficient encoding of vector information used for inter-frame predictive coding, even when the reference frame used in the inter-frame predictive coding differs between the target encoding region and its neighbouring region.
