Abstract
Implementations are provided that relate, for example, to view tiling in video encoding and decoding. A particular implementation accesses a video picture that includes multiple pictures combined into a single picture, and accesses additional information indicating how the multiple pictures in the accessed video picture are combined. The accessed information includes spatial interleaving information and sampling information. Another implementation encodes a video picture that includes multiple pictures combined into a single picture, and generates information indicating how the multiple pictures in the accessed video picture are combined. The generated information includes spatial interleaving information and sampling information. A bitstream is formed that includes the encoded video picture and the generated information. Another implementation provides a data structure for transmitting the generated information.
