METHOD AND DEVICE FOR ENCODING/DECODING MOTION VECTOR

摘要

The method for encoding a motion vector according to an embodiment of the present invention comprises: a step for determining a first motion vector and a second motion vector related to a current block to be encoded; a step for determining a predicted motion vector for each of the first motion vector and the second motion vector; a step for calculating a first differential motion vector, which is a differential between the first motion vector and the predicted motion vector of the first motion vector, and a second differential motion vector, which is a differential between the second motion vector and the predicted motion vector of the second motion vector; and a step for encoding the first differential motion vector and the second differential motion vector, wherein the resolution of the first motion vector and the resolution of the second motion vector are different from each other.
