    Abstract: An image decoding method, which is performed by a decoding apparatus, includes the steps of: deriving a frequency domain-neighboring block for a neighboring block of a current block in a spatial domain; deriving a frequency domain-prediction block for the current block by applying a prediction pattern to the frequency domain-neighboring block; generating a frequency domain-reconstructed block for the current block on the basis of the frequency domain-prediction block; and generating a reconstructed block for the current block in the spatial domain on the basis of the frequency inverse transform of the frequency domain-reconstructed block. The present invention can generate a prediction block for a current block in a frequency domain, and accordingly can more efficiently reconstruct a complex image.

    Abstract: A method for processing a video signal according to the present invention comprises the steps of: determining a motion vector list comprising at least one of a spatial motion vector, a temporal motion vector, and a mutation vector as a motion vector candidate of a target block; extracting motion vector identification information for specifying the motion vector candidate to be used as a predicted motion vector of the target block; setting the motion vector candidate corresponding to the motion vector identification information as the predicted motion vector of the target block; and performing motion compensation based on the predicted motion vector. The present invention forms the motion vector candidate and derives the motion vector of the target and derives the motion vector of the target block therefrom, thus enabling a more accurate prediction of the motion vector, and thereby reduces the amount of transmitted residual data and improves coding efficiency.

    Abstract: According to the present invention, an inter-view motion vector of a current coding unit is acquired using parallel processing information, and a motion vector of a current prediction unit in the current coding unit is acquired in parallel using the inter-view motion vector of the current coding unit. The present invention relates to a method and device for processing a video signal, wherein a motion vector prediction value of the current prediction unit is acquired by comparing output order information of a reference picture corresponding to the current prediction unit and output order information of a reference picture corresponding to a corresponding block. According to the present invention, through a parallel processing step, a multi-view point video image can be quickly restored, and the accuracy of the motion vector prediction value can be increased using motion information corresponding to the reference picture of the corresponding block of a different view point from the current prediction unit.
