Information processing apparatus and method
The present disclosure relates to an information processing apparatus and method that allows a stream of sub-pictures to be more easily selected. A control file is generated that manages image encoded data for each of a plurality of sub-pictures into which an entire picture is divided and which is then encoded, the control file including region-related information related to a region in the entire picture corresponding to the sub-picture, as information different from arrangement information for each of picture regions, the control file being used for controlling distribution of the image encoded data. The present disclosure can be applied to, for example, an information processing apparatus, an image processing apparatus, an image encoding apparatus, a file generating apparatus, a file transmission apparatus, a distribution apparatus, a file reception apparatus, an image decoding apparatus, or a reproduction apparatus.
1. An information processing apparatus comprising:
circuitry configured to:
generate a content file including image encoded data in which an entire picture is encoded and a predetermined metadata Box,
wherein the predetermined metadata Box shows that a projected picture, which is a projected plane image that maps a three-dimensional structure image to a plane, and the entire picture constructed from a sub-picture are the same, and
wherein the predetermined metadata Box indicates that region-wise packing has not been applied to the entire picture.
2. The information processing apparatus of claim 1 , wherein a number value indicates that the region-wise packing has not been applied to the entire picture.
3. The information processing apparatus of claim 1 , wherein a flag field indicates that the region-wise packing has not been applied to the entire picture.
4. The information processing apparatus of claim 3 , wherein the flag field having a value of 1 indicates that the region-wise packing has not been applied to the entire picture.
5. The information processing apparatus of claim 1 , wherein a flag field having a value of 0 indicates that the entire picture is different from the projected picture.
6. The information processing apparatus of claim 1 , wherein a flag field having a value of 1 indicates that the entire picture is identical to the projected picture.
7. The information processing apparatus of claim 6 , wherein the flag field is in a Sub Picture Composition Box.
8. The information processing apparatus of claim 1 , wherein presence or absence of another metadata Box indicates whether or not the entire picture is identical to the projected picture.
9. An information processing method comprising:
generating, by circuitry, a content file including image encoded data in which an entire picture is encoded and a predetermined metadata Box,
wherein the predetermined metadata Box shows that a projected picture, which is a projected plane image that maps a three-dimensional structure image to a plane, and the entire picture constructed from a sub-picture are the same, and
wherein the predetermined metadata Box indicates that region-wise packing has not been applied to the entire picture.
10. The information processing method of claim 9 , wherein a number value indicates that the region-wise packing has not been applied to the entire picture.
11. The information processing method of claim 9 , wherein a flag field indicates that the region-wise packing has not been applied to the entire picture.
12. The information processing method of claim 11 , wherein the flag field having a value of 1 indicates that the region-wise packing has not been applied to the entire picture.
13. The information processing method of claim 9 , wherein a flag field having a value of 0 indicates that the entire picture is different from the projected picture.
14. An information processing apparatus comprising:
circuitry configured to:
acquire a content file including image encoded data in which an entire picture is encoded and a predetermined metadata Box,
wherein the predetermined metadata Box shows that a projected picture, which is a projected plane image that maps a three-dimensional structure image to a plane, and the entire picture constructed from a sub-picture are the same, and
wherein the predetermined metadata Box indicates that region-wise packing has not been applied to the entire picture; and
process the content file.
15. The information processing apparatus of claim 14 , wherein a number value indicates that the region-wise packing has not been applied to the entire picture.
16. The information processing apparatus of claim 14 , wherein a flag field indicates that the region-wise packing has not been applied to the entire picture.
17. The information processing apparatus of claim 16 , wherein the flag field having a value of 1 indicates that the region-wise packing has not been applied to the entire picture.
18. The information processing apparatus of claim 14 , wherein a flag field having a value of 0 indicates that the entire picture is different from the projected picture.
