Method and apparatus for decoding/encoding a multi-view video signal with inter-view reference picture list management

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 stream including a random access picture, the random access picture including a random access slice, the random access slice referencing only slices corresponding to a same time and a different view of the random access picture;
• obtaining, with the decoding apparatus, initialization information of a reference picture list for the random access slice from the multi-view video stream, the initialization information representing a reference relation between a plurality of views, the initialization information including view number information and view identification information;
• obtaining, with the decoding apparatus, type information indicating whether the random access slice is predicted from one reference picture or two reference pictures;
• initializing, with the decoding apparatus, the reference picture list,
• the initializing including ordering reference pictures used for inter-view prediction of the random access slice, the reference pictures being specified by the view number information and the view identification information according to the type information,
• the ordering including assigning an inter-view reference index to each reference picture, the inter-view reference index identifying a reference picture in the reference picture list used for inter-view prediction of a block to be decoded, the block to be decoded having a same time with the reference pictures and a different view from the reference pictures;
• obtaining, with the decoding apparatus, modification information for the initialized reference picture list from the multi-view video stream, the modification information representing how to change the inter-view reference index in the initialized reference picture list;
• determining, with the decoding apparatus, an assignment modification value for changing the inter-view reference index in the initialized reference picture list according to the modification information;
• modifying, with the decoding apparatus, the initialized reference picture list for inter-view prediction, wherein the modifying includes reordering the reference picture by changing the inter-view reference index assigned to the 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 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.
