    摘要: The method includes receiving a multi-view video stream including a random access picture, which includes a random access slice. 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 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. A prediction value of a macroblock in the random access picture is determined based on the modified reference picture list.

    摘要: 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. A reference picture list is initialized using initialization information. 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. A prediction value of a macroblock in the random access picture is determined based on the modified reference picture list, and the macroblock is decoded using the prediction value.

    摘要: The present invention relates to a method that uses a motion vector of a predictive video frame of a sub-layer to encode a video signal and decode encoded video data. The method encodes a video signal using a preset method to a bit stream of a base layer while encoding the video signal using a scalable MCTF method to a bit stream of an enhanced layer. When an arbitrary frame of the video signal is encoded, information, enabling at least one vector, derived from a first motion vector of a first block included in the bit stream of the base layer in the same direction as the first motion vector, to be used as a motion vector of an image block in the arbitrary frame, is recorded in the bit stream of the enhanced layer. The first motion vector is directed in the same direction as a temporal direction from the arbitrary frame to the first block.
