  • Patent number: 8320456
    Abstract: An apparatus for processing a video signal and method thereof are disclosed. The present invention includes determining an intra reference block in a current view layer by using an intra motion information of an inter-reference unit in a reference view layer, the inter-reference unit being partially decoded and decoding the current block in the current view layer by using the intra-reference block. Accordingly, in coding a video signal, pictures failing to be substantially referred to for reconstruction of a current picture can be omitted. According to another aspect of the present invention, residual information having high redundancy is omitted to raise a compression ratio.

    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.
