PREDICTING MOVEMENT VECTOR FOR VIDEO CODING Russian patent published in 2015 - IPC H04N19/52 

Abstract RU 2550554 C2

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. A method of coding of video data according to which the spatial movement vectors are determined - the candidates connected with the current section of the current video frame, and the spatial movement vectors - candidates contain the movement vectors defined for the adjoining sections of the current video frame adjacent to the current section; a time movement vector - candidate connected with the current section of the current video frame is determined, and the time movement vector - candidate contains the movement vector determined for the section of the reference video frame; the spatial movement vectors - candidates are cut for removal of duplicated from spatial movement vectors - candidates, without consideration of the time movement vector - candidate for cutting off the process time; the time movement vector - candidate or one of spatial movement vectors - candidates which remained after cutting off is selected, for the selected movement vector - candidate for prediction of the movement vector; an index which identifies the location of one selected movement vectors - candidate in the list from a time movement vector - candidate and spatial movement vectors - candidates remained after cutting off is determined; also the index is signalled in the bit flow.

EFFECT: improvement of method efficiency.
