Tiling in video encoding and decoding
Implementations are provided that relate, for example, to view tiling in video encoding and decoding. A particular method includes accessing a video picture that includes multiple pictures combined into a single picture ( 826 ), accessing information indicating how the multiple pictures in the accessed video picture are combined ( 806, 808, 822 ), decoding the video picture to provide a decoded representation of at least one of the multiple pictures ( 824, 826 ), and providing the accessed information and the decoded video picture as output ( 824, 826 ). Some other implementations format or process the information that indicates how multiple pictures included in a single video picture are combined into the single video picture, and format or process an encoded representation of the combined multiple pictures.
1. A method comprising:
combining multiple pictures into a video picture, the multiple pictures including a first picture of a first view of a multi-view video and a second picture of a second view of the multi-view video in which a common object or region appears shifted from one view to the other;
generating information indicating how the multiple pictures are combined, wherein the generated information indicates whether at least one of the multiple pictures is individually flipped in one or both of a horizontal direction and a vertical direction;
encoding the video picture to provide an encoded representation of the combined multiple pictures; and
providing the generated information and the encoded representation as output.
2. The method of claim 1 , wherein the first picture is arranged alongside the second picture in the video picture.
3. The method of claim 1 , wherein the first picture is arranged above the second picture in the video picture.
4. The method of claim 1 , wherein pixels of the first and second pictures are alternately interlaced.
