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. An apparatus for decoding coded video pictures, the apparatus comprising:
an input for receiving a coded video bitstream comprising coded video pictures; and
a processor, wherein the processor:
determines from the received bitstream a single picture, wherein the single picture includes 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;
accesses information to determine how the first picture and the second picture are tiled together, wherein the accessed information indicates that the first picture and the second picture are arranged side-by-side, and at least one of the first picture and the second picture is individually flipped in the horizontal direction; and
decodes the single picture into the first picture and the second picture.
2. The apparatus of claim 1 , wherein both the first picture and the second picture are individually flipped in the horizontal direction.
3. The apparatus of claim 1 , wherein only the first picture is flipped.
4. A non-transitory processor readable medium having stored thereon encoded video bitstream data for decoding by a decoder, the video bitstream data comprising:
an encoded picture section including an encoding of a single video picture, the single video picture 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 arranged into the single video picture; and
a signaling section including an encoding of an indication that indicates whether the first picture and the second picture are arranged side-by-side and whether at least one of the first picture and the second picture is individually flipped in the horizontal direction, the indication allowing decoding by the decoder of the encoded single video picture into decoded versions of the first picture and the second picture.
5. The processor readable medium of claim 4 , wherein the signaling section indication indicates that both the first picture and the second picture are flipped in the horizontal direction.
6. An apparatus for encoding video pictures into a coded bitstream, the apparatus comprising:
an input for receiving video pictures of a multi-view video;
a processor, wherein the processor
combines multiple pictures into a single video picture, the multiple pictures including a first picture of a first view of the multi-view video and a second picture of a second view of the multi-view video;
generates a signaling section indicating how the multiple pictures are combined, wherein the generated information indicates that the first picture and the second picture are arranged side-by-side and that at least one of the first picture and the second picture is individually flipped;
encodes the single video picture to provide an encoded representation of the combined multiple pictures; and
combines the signaling section and the encoded representation as output.
7. The apparatus of claim 6 , wherein the signaling section indicates that both of the first picture and the second picture are flipped in the horizontal direction.
