Abstract: Systems, methods, and instrumentalities are provided to implement video coding system (VCS). The VCS may be configured to receive a video signal, which may include one or more layers (e.g., a base layer (BL) and/or one or more enhancement layers (ELs)). The VCS may be configured to process a BL picture into an inter-layer reference (ILR) picture, e.g., using picture level inter-layer prediction process. The VCS may be configured to select one or both of the processed ILR picture or an enhancement layer (EL) reference picture. The selected reference picture(s) may comprise one of the EL reference picture, or the ILR picture. The VCS may be configured to predict a current EL picture using one or more of the selected ILR picture or the EL reference picture. The VCS may be configured to store the processed ILR picture in an EL decoded picture buffer (DPB).

Abstract: An embodiment of the invention is a method that provides common data and enforces multiple view consistency. In a preferred embodiment, a coordinate alignment matrix is generated after initial warped views are formed. The matrix is used efficiently to repair holes/occlusions when synthesizing final views. In another preferred embodiment, a common background layer is generated based upon initial warped views. Holes are repaired on the common background layer, which can then be used for synthesizing final views. The cost of the latter method is sub-linear, meaning that additional views can be generated with lesser cost. Preferred methods of the invention also use a placement matrix to generate initial warped views, which simplifies warping to a look-up operation.
