Abstract:
The present invention relates to a method and apparatus for encoding or decoding a video signal. According to the present invention, a plurality of reference units for image prediction of the current unit is acquired and combined to obtain a unit prediction value, thereby improving the accuracy of image prediction. More particularly, the present invention relates to a method for inducing a variety of reference units using a motion vector prediction value or a motion vector which is used in conventional inter-prediction, and also relates to a method which combines the reference units so as to obtain the prediction value for the current unit. In addition, the present invention relates to a method which involves acquiring a plurality of reference units for a merging mode, and combining the reference units so as to perform image prediction.
