Abstract:
1. A method for decoding a multi-view video data in a multi-view video data stream, comprising: receiving the multi-view video data stream, the multi-view video data stream including a random access picture, the random access picture including a random access slice, the random access slice referencing only slices corresponding to a same time and a different view of the random access picture; obtaining initialization information of a reference picture list for the random access slice, the initialization information representing a reference relation for a single direction or a bi-direction between a plurality of views, the initialization information including view number information and view identification information, the view number information indicating a number of reference views of the random access picture, and the view identification information providing a view identifier of each reference view for the random access picture; obtaining type information indicating whether the random access slice is predicted from one reference picture or two reference pictures; initializing the reference picture list using the view number information and the view identification information according to the type information; obtaining modification information for the initialized reference picture list from the multi-view video data stream, the modification information indicating that a reference picture in the initialized reference picture list is to be reordered; determining an assignment modification value according to the modification information, the assignment modification value specifying an inter-view reference index of the reference picture to be reordered; modifying the initialized reference picture list, wherein the modifying includes selecting the reference picture having the inter-view reference index equal to the determined assignment modification value and reordering the reference picture by changing the inter-view reference index of the selected reference picture; determining a prediction value of a macroblock in the random access picture based on the modified reference picture list; and decoding the macroblock using the prediction value, wherein the initialization information is obtained from an extension area of a sequence header.
