  • Publication number: 20100316135
    Abstract: The method includes receiving a multi-view video stream including a random access picture, which includes a random access slice. The random access slice references only a slice corresponding to a same time and a different view of the random access picture. Type information indicating whether the random access slice is predicted from one or two reference pictures is obtained, and a reference picture list is initialized using view number information and view identification information included in obtained initialization information according to the type information. The initialization information is obtained based on a value indicating decoding order between the plurality of views. The initialized reference picture list is modified based on modification information representing how to assign an inter-view reference index in the initialized reference picture list.
