1. A video decoding method comprising:
identifying at least one non-refined motion vector associated with a first block in a picture;
refining the at least one non-refined motion vector to generate at least one refined motion vector associated with the first block;
for a second block in the picture neighboring the first block, determining whether the second block is in a different segment of the picture from the first block;
predicting motion information of the second block, wherein, in response to a determination that the second block is in the same segment of the picture as the first block, the at least one refined motion vector is used as a predictor of the motion information of the second block; and
predicting the second block based on the predicted motion information.
