Abstract:
The present invention discloses a method and apparatus for encoding or decoding a video signal. The method for processing a video signal according to the present invention uses a merging mode in which prediction information on a neighbor unit is used instead of transmitting prediction information on the present unit, so as to improve coding efficiency. In this case, the number of available candidate units for merging among the units in a predetermined position is determined, and information for the merging mode is acquired on the basis of the number of the available candidate units for merging. The unit to be merged is determined using the information for the merging mode, and prediction information on the unit to be merged is acquired. The prediction value for the present unit is acquired using the prediction information on the unit to be merged, and the present unit is restored using the acquired prediction value.
