Abstract: PURPOSE: A prediction motion vector inducing method and an apparatus using the same are provided to present a vector list configuration method of a candidate prediction motion to improve video encoding/decoding efficiency. CONSTITUTION: A video encoding device (100) includes an entropy encoder (150) which encodes the information about a prediction motion vector used to predict the gap of a prediction object block between candidate prediction motions which are included in a candidate prediction motion vector list, and prediction units (111,120) which create a vector list of the candidate prediction motions by determining the information about a time-based candidate prediction motion vector based on the information about multiple spatial candidate prediction motion vectors.
