Abstract
A video encoding apparatus using an inter-prediction includes: a video encoder to determine a current motion vector of a current block, predict the current block by using the determined current motion vector, and encode a residual block representing a difference between the predicted block and the current block; and a motion vector encoder to determine a candidate predicted motion vector set based on motion information of neighboring blocks of the current block, select a predicted motion vector of the current motion vector from among the two candidate predicted motion vectors in the candidate predicted motion vector set, and encode a differential vector representing a difference between the current motion vector and the selected predicted motion vector and a predicted motion vector index indicating the selected predicted motion vector among the two candidate predicted motion vectors.
