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.
