MOTION VECTOR PREDICTION AT VIDEO ENCODING Russian patent published in 2016 - IPC H04N19/597 

FIELD: physics.

SUBSTANCE: claimed process comprises identification of the first set of video data associated with the first vector on motion disparateness at the first temporary location from the first type. It comprises also the identification of the second motion vector for the second unit of video data in the second type other than the first type on the basis of the second vector that makes the motion disparateness vector. Motion vector predictor for the second motion vector. Note here that said motion predictor is based on the first motion disparateness vector. a definite motion vector predictor is added to the list of motion vector predictor candidates for prediction of the second motion vector which is not the motion disparateness vector. Possibility of motion vector predictor determination from the first motion disparateness vector without addition of said motion disparateness vector is not added to said list of candidates. Prediction data are encoded for the second unit with the help of motion vector predictor from the list of predictor candidates.

EFFECT: prevented use of incompatible motion vector as the motion vector predictor.
