FIELD: system for encoding moving image, in particular, method for determining movement vector being predicted, of image block in B-frame in process of decoding of moving image. ^ SUBSTANCE: in accordance to method, at least one movement vector is produced for at least one block, different from current block, while aforementioned at least one block is related to one, at least, supporting frame in a row of supporting frame, movement vector is predicted for current block on basis of received one, at least, movement vector, while prediction operation includes also operation of comparison of value of order number of B-frame to value of order number of one, at least, supporting frame, while movement vector for current block and aforementioned one, at least, movement vector are vectors of forward movement. ^ EFFECT: increased efficiency. ^ 2 cl, 1 dwg |
