Abstract
Official abstract text for this publication.
The present invention relates to a method and apparatus for processing a video signal, which can increase the accuracy of the motion vector prediction through motion vector scaling which takes a difference in the temporal distance between reference pictures into consideration. To this end, the present invention provides a video signal processing method and a video signal processing apparatus using the same, and the method comprises the steps of: scaling at least one neighboring partition motion vector for a motion vector prediction of the current partition; scaling the neighboring partition motion vector, which has been selected, when the reference picture of the neighboring partition motion vector is different from the reference picture of the current partition; acquiring a motion vector prediction value of the current partition using the scaled motion vector; and acquiring a motion vector of the current partition using the motion vector prediction value.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of processing a video signal, the method comprising: obtaining index information from the video signal, the index information specifying a motion vector candidate to be used as a motion vector predictor of a current block; constructing a motion vector candidate set of the current block, the motion vector candidate set including a plurality of motion vector candidates, the plurality of motion vector candidates including a spatial motion vecto…
