Abstract

FIELD: methods for encoding moving images, in particular, method for determining movement vector for producing movement vectors in direct prediction mode for current block in bidirectional prediction frame.
SUBSTANCE: in accordance to the method, movement vector of list 0 is selected as movement vector for producing aforementioned movement vectors in direct prediction mode, if shifted block for current block has movement vectors of both list 0 and list 1.
EFFECT: increased probability of selection of direct prediction mode and increased efficiency of encoding.
