A method for decoding a multi-view video data in a multi-view video stream, comprising: receiving the multi-view video data stream including a random access picture including a random access slice and a profile indicator, the random access slice referencing only slices corresponding to a same time and a different view of the random access picture, the profile indicator indicating that a received video stream is the multi-view video data stream; obtaining a random access flag for inter-view prediction, the random access flag indicating whether a picture is the random access picture; obtaining initialization information for the random access slice based on the random access flag and the profile indicator, the initialization information representing information recognizing a predictive structure between a plurality of views, the initialization information including view number information and view identification information; obtaining type information indicating whether the random access slice is predicted from one reference picture or two reference pictures; initializing a reference picture list for the inter-view prediction using the view number information, the view identification information, and the type information; characterized in that the method further comprises: obtaining modification information for the initialized reference picture list from the multi-view video data stream, the modification information representing how to assign a reference index in the initialized reference picture list; determining an assignment modification value for modifying the reference index in the initialized reference picture list according to the modification information; modifying the initialized reference picture list for the inter-view prediction using the determined assignment modification value; determining a prediction value of a macroblock in the random access picture based on the modified initialized 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. receiving the multi-view video data stream including a random access picture including a random access slice and a profile indicator, the random access slice referencing only slices corresponding to a same time and a different view of the random access picture, the profile indicator indicating that a received video stream is the multi-view video data stream; obtaining a random access flag for inter-view prediction, the random access flag indicating whether a picture is the random access picture; obtaining initialization information for the random access slice based on the random access flag and the profile indicator, the initialization information representing information recognizing a predictive structure between a plurality of views, the initialization information including view number information and view identification information; obtaining type information indicating whether the random access slice is predicted from one reference picture or two reference pictures; initializing a reference picture list for the inter-view prediction using the view number information, the view identification information, and the type information; characterized in that the method further comprises: obtaining modification information for the initialized reference picture list from the multi-view video data stream, the modification information representing how to assign a reference index in the initialized reference picture list; determining an assignment modification value for modifying the reference index in the initialized reference picture list according to the modification information; modifying the initialized reference picture list for the inter-view prediction using the determined assignment modification value; determining a prediction value of a macroblock in the random access picture based on the modified initialized 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. obtaining modification information for the initialized reference picture list from the multi-view video data stream, the modification information representing how to assign a reference index in the initialized reference picture list; determining an assignment modification value for modifying the reference index in the initialized reference picture list according to the modification information; modifying the initialized reference picture list for the inter-view prediction using the determined assignment modification value; determining a prediction value of a macroblock in the random access picture based on the modified initialized 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.
