METHOD AND DEVICE FOR PROCESSING VIDEO SIGNAL

摘要

The present invention relates to a method for processing a video signal, particularly to a method for applying an interpolation filter for an inter-prediction. The interpolation filer of the present invention can be expressed in one or more parameters, and can effectively transmit this information therefrom. In the present invention, a filter being applied to the present frame is determined through information that indicates whether the filter is adaptive, or through information available in given conditions. Also, according to the present invention, different interpolation filters can be used with a frame or a unit smaller than the frame, and in this process, the location of sub-pel and characteristics of the present unit can be considered. In the present invention, various interpolation filters having different coefficient values or shapes are considered.
