  • Patent number: 10397604
    Abstract: This document discloses a method and apparatus for image encoding/decoding which support multiple layers. The method for image decoding comprises analyzing a video parameter set (VPS) extension for layer dependency on a current layer, analyzing slices for layer dependency on a current slice by determining whether not to apply layer dependency to the current slice or to apply new layer dependency to the current slice, the new layer dependency determining within a range of layer dependency analyzed from the VPS extension, and constructing a reference picture list about the current layer based on at least one of layer dependency analyzed from the VPS extension and layer dependency analyzed from the slice.

  • Patent number: 10277918
    Abstract: 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.

    Abstract: Disclosed is a technique related to a method for a motion vector prediction and a residual prediction for a multi-view video and an apparatus for performing the method. A method for decoding a motion vector for a multi-view video comprises the steps of: determining a motion prediction method performed on a current block which is an object to be decoded and a corresponding block corresponding to the current block; and generating a motion vector prediction value of the current block using a motion vector of the corresponding block on the basis of the determined motion prediction method. Thus, a temporal motion vector can be adaptively predicted according to a motion vector prediction method of the current block and the corresponding block.
