Claim Text:
1. A video decoding apparatus comprising: an entropy decoding processor configured to decode information on a prediction motion vector used to perform inter prediction on a prediction target block among candidate prediction motion vectors comprised in a candidate prediction motion vector list; and a prediction unit to generate the candidate prediction motion vector list by determining information on a plurality of spatial candidate prediction motion vectors from a neighboring prediction block to the prediction target block and determining information on a temporal candidate prediction motion vector based on the information on the plurality of spatial candidate prediction motion vectors, wherein the information on the spatial candidate prediction motion vector comprises at least one of first spatial candidate prediction motion vector availability information and a first spatial candidate prediction motion vector and at least one of second spatial candidate prediction motion vector availability information and a second spatial candidate prediction motion vectors, the information on the temporal candidate prediction motion vector comprises at least one of temporal candidate prediction motion vector availability information and the temporal candidate prediction motion vector, and in response to both the first spatial candidate prediction motion vector and the second spatial candidate prediction motion vector being available and the first spatial candidate prediction motion vector and the second spatial candidate prediction motion vector being different from each other, the prediction processor is configured to determine the temporal candidate prediction motion vector availability information such that the temporal candidate prediction motion vector is unavailable.
