HIGH-LEVEL SYNTACTIC EXPANSIONS FOR HIGH-EFFICIENT VIDEO CODING Russian patent published in 2017 - IPC H04N19/597 H04N19/46 H04N19/70 H04N19/30 H04N19/513 H04N19/58 

FIELD: physics.

SUBSTANCE: method for decoding the video data comprises decoding the second image data that relates to the image order count value (POC) for the first video data image; decoding the second image data that relates to the image identifier of the second dimension for the first image; decoding the second image based on the POC value and the image identifier of the second dimension of the first image; determining that the first motion vector of the first block of the second image refers to a short-term reference image; determining that the second motion vector of the second block of the second image refers to a long-term reference image; and based on the determination, the prohibition of predicting the motion vector between the first motion vector of the first block of the second image and the second motion vector of the second block of the second image.

EFFECT: increasing the efficiency of encoding, decoding video data by prohibiting the prediction of the motion vector.
