Abstract:
1. A method for decoding multi-view video data in a multi-view video stream with a decoding apparatus, comprising: receiving, with the decoding apparatus, the multi-view video stream, the multi-view video steam including video data for each of a plurality of views, each of the plurality of views corresponding to a different spatial angle, the multi-view video stream including a random access picture, the random access picture including a random access slice, the random access slice referencing only a slice corresponding to a same time and a different view of the random access picture; obtaining, with the decoding apparatus, initialization information of an inter-view reference picture list for the random access slice, the initialization information representing view relationships between the plurality of views, the initialization information including view number information and view identification information for the plurality of views, the view number information indicating a number of inter-view reference pictures used for inter-view prediction of the random access picture, the view identification information to which of the plurality of views each of the inter-view reference pictures belongs; initializing, with the decoding apparatus, the inter-view reference picture list for inter-view prediction, the initializing including ordering the inter-view reference pictures for the random access picture in the inter-view reference picture list, the ordering including assigning an inter-view reference index to each of the inter-view reference pictures, the inter-view reference index identifying an inter-view reference picture in the inter-view reference picture list used for inter-view prediction of a block to be decoded in the random access picture, the assigning being performed using the view number information and the view identification information, the block to be decoded having a same time with the inter-view reference pictures and a different view from the inter-view reference pictures, the inter-view reference picture being appended to an initialized temporal reference picture list for temporal prediction, the random access picture and at least one of the inter-view reference pictures included in the initialized inter-view reference picture list having a same picture order count; deriving, with the decoding apparatus, an adjustment value for adjusting an assignment modification value within a scope of the view number information; determining, with the decoding apparatus, the assignment modification value for reordering the inter-view reference picture in the initialized inter-view reference picture list according to the adjustment value; modifying, with the decoding apparatus, the initialized inter-view reference picture list for inter-view prediction, the modifying including reordering the inter-view reference picture by changing the inter-view reference index assigned to the inter-view reference picture based on the determined assignment modification value; determining, with the decoding apparatus, a prediction value of a macroblock in the random access picture based on the modified inter-view reference picture list; and decoding, with the decoding apparatus, the macroblock using the prediction value, wherein the initialization information is obtained based on a value indicating decoding order between the plurality of views.
