Abstract:
Disclosed are a method and device for encoding or decoding video signals. The video signal processing method according to the present invention can enhance processing efficiency by using a structure whereby a single unit is recursively divided into a plurality of units. A method is provided in which bits can be used efficiency by hierarchically employing coding block pattern information under a unit structure able to be divided in this way. Further, residual data is rearranged so as to allow efficient coding by employing spatial distribution of the residual data.
