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 non-transitory processor readable medium having stored thereon encoded video stream data for decoding by a decoder, the video data comprising:
an encoded picture section including an encoding of a video picture, the 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 video picture; and
a signaling section including an encoding of an indication that indicates whether at least one of the first picture and the second picture is individually flipped, the indication allowing decoding by the decoder of the encoded video picture into decoded versions of the first picture and the second picture.
2. The processor readable medium of claim 1 , wherein the first picture is arranged alongside the second picture in the video picture.
3. The processor readable medium of claim 1 , wherein the first picture is arranged above the second picture in the video picture.
4. The processor readable medium of claim 1 , wherein pixels of the first and second pictures are alternately interlaced.
5. The processor readable medium of claim 1 , wherein the signaling section indicates that at least one of the first picture and the second picture is flipped in the horizontal direction.
6. The processor readable medium of claim 1 , wherein the signaling section indicates that at least one of the first picture and the second picture is flipped in the vertical direction.
7. A method for decoding a video bitstream with a processor, the method comprising:
by apparatus comprising one or more data processors configured by software, one or more programmable logic devices, one or more logic circuits or a combination thereof:
receiving a coded bitstream, wherein the coded bitstream comprises:
an encoded picture section including an encoding of a video picture, the 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 video picture; and
a signaling section including an encoding of an indication that indicates whether at least one of the first picture and the second picture is individually flipped;
and decoding the encoded video picture into decoded versions of the first picture and the second picture based on the flipping information extracted from the signaling section.
8. The method of claim 7 , wherein the first picture is arranged alongside the second picture in the video picture.
9. The method of claim 7 , wherein the first picture is arranged above the second picture in the video picture.
10. The method of claim 7 , wherein the signaling section indicates that at least one of the first picture and the second picture is flipped in the horizontal direction.
11. The method of claim 7 , wherein the signaling section indicates that at least one of the first picture and the second picture is flipped in the vertical direction.
12. A method for encoding video pictures with an encoder, the 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;
generating a signaling section indicating how the multiple pictures are combined, wherein the generated information indicates whether at least one of the multiple pictures is individually flipped;
encoding the video picture to provide an encoded representation of the combined multiple pictures; and
combining the signaling section and the encoded representation as output.
13. The method of claim 12 , wherein the signaling section indicates that at least one of the first picture and the second picture is flipped in the horizontal direction.
14. The method of claim 12 , wherein the signaling section indicates that at least one of the first picture and the second picture is flipped in the vertical direction.
