摘要： The present invention relates to a method and device for sharing a candidate list. A method of generating a merging candidate list for a predictive block may include: producing, on the basis of a coding block including a predictive block on which a parallel merging process is performed, at least one of a spatial merging candidate and a temporal merging candidate of the predictive block; and generating a single merging candidate list for the coding block on the basis of the produced merging candidate. Thus, it is possible to increase processing speeds for coding and decoding by performing inter-picture prediction in parallel on a plurality of predictive blocks.

摘要： The present invention is related to a method for moving the position of a base view from an arbitrary GOP (Group Of Pictures) start position to implement an efficient encoding structure in multi-view video encoding. The existing multi-view video encoding method exhibits low encoding efficiency when correlation between the base view and a dependent view is low, since the base view is assumed to be fixed. Moreover, in case the view in a live broadcasting program desired by a producer changes from the base view to another, the user has to consume more bit streams and decoder complexity than those consumed when decoding is performed with respect to the base view. Therefore, to alleviate the drawbacks of the existing multi-view video encoding method, the present invention provides a method for designing syntax elements by which the base view can be moved, thereby supporting an efficient encoding structure.

摘要： According to the present invention, an image encoding/decoding method comprises the steps of: performing an intra prediction on a current block so as to generate a prediction block; performing filtering on a filtering target pixel in the prediction block on the basis of the intra prediction mode of the current block so as to generate a final prediction block; and generating a reconstructed block on the basis of a reconstructed differential block corresponding to the current block and on the final prediction block. According to the present invention, image encoding/decoding efficiency can be improved.

摘要： The present invention relates to a method and apparatus for setting a reference picture index of a temporal merging candidate. An inter-picture prediction method using a temporal merging candidate can include the steps of: determining a reference picture index for a current block; and inducing a temporal merging candidate block of the current block and calculating a temporal merging candidate from the temporal merging candidate block, wherein the reference picture index of the temporal merging candidate can be calculated regardless of whether a block other than the current block is decoded. Accordingly, a video processing speed can be increased and video processing complexity can be reduced.
