A method for processing a video data stream, a video decoding apparatus, and a method for encoding data stream are provided. The method includes: receiving a video data stream; generating a layer list using at least the patch-layer association information, the layer list including a first layer associated with the first view, the first layer being based on a first depth of the first view; assigning a first layer identification to the first layer; updating the view list section by adding the first layer as a second view; selecting a first target view for rendering on an output device; selecting one or more patches using at least the layer list and the patch list section; combining the selected one or more patches to form a first intermediate output frame; and performing post processing using at least the view list section.
