Patent ID: 8724700

Claim:
A method for managing a reference picture by a decoder, comprising: receiving a multi-view video data stream, the multi-view video data stream 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 data 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 random access flag from the multi-view video data stream, the random access flag indicating whether a type of a current picture is a random access picture; initializing a reference picture list of the random access picture when the type of the current picture represents the random access picture according to the random access flag, the initializing including ordering inter-view reference pictures in the 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 reference picture list used for inter-view prediction of a block to be decoded in the random access picture, the assigning being performed using inter-view reference 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 information indicating a prediction relationship between the plurality of views, the inter-view reference information including view number information and view identification information, the view number information indicating a number of the inter-view reference pictures used for inter-view prediction of the random access picture and the view identification information identifying to which of the plurality of views each of the inter-view reference pictures belongs, the random access picture and at least one of the inter-view reference pictures included in the initialized reference picture list having a same picture order count; obtaining modification information for the initialized reference picture list from the multi-view video data stream, the modification information indicating the inter-view reference picture is reordered; obtaining an assignment modification value for changing the inter-view reference index in the initialized reference picture list according to the modification information; and modifying the initialized reference picture list of the random access picture, 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 assignment modification value, wherein the inter-view reference picture is identified based on picture identification information identifying a view number of the inter-view reference picture.
