Abstract: Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.

Abstract: A method for decoding a video including a plurality of views, according to one embodiment of the present invention, comprises the steps of: configuring a base merge motion candidate list by using motion information of neighboring blocks and a time correspondence block of a current block; configuring an extended merge motion information list by using motion information of a depth information map and a video view different from the current block; and determining whether neighboring block motion information contained in the base merge motion candidate list is derived through view synthesis prediction.

Abstract: According to the present invention, a video decoding method comprises: a step of decoding a first bitstream corresponding to a base layer image based on first decoding information corresponding to the image that belongs to the view which is different from the view to which the base layer image belongs; and a step of decoding a second bitstream corresponding to an enhancement layer image based on second decoding information corresponding to the base layer image and third decoding information corresponding to the image that belongs to the view which is different from the view to which the enhancement layer image belongs.
