Abstract

The present disclosure relates to an information processing device and method for adaptively supplying data of partial images. The information processing device includes: a partial image information generation unit configured to generate partial image information which is information regarding each partial image which is a part of an entire image; and a metadata generation unit configured to generate metadata to be used for supply of a bit stream of the entire image and supply of a bit stream of the partial image using the partial image information generated by the partial image information generation unit. For example, the present disclosure can be applied to an information processing device that performs a process for adaptively supplying image data.

First claim

The invention claimed is:

1. An information processing device comprising:
circuitry configured to
generate metadata used for provision of a bit stream of a whole image and provision of a bit stream of a partial image that is part of the whole image, and
initiate storage into the metadata of partial image information on the partial image,

wherein the partial image is composed of at least one tile image,
wherein the partial image information includes a view type (viewtype) indicating whether or not the partial image information is a partial image,
wherein the partial image information includes group identification information for identifying a group of partial images that can be displayed as one image, and
wherein the partial image information includes position information indicating a position of the partial image within the whole image.

2. The information processing device according to claim 1 ,
wherein the position information indicates an upper left position of the partial image.

3. The information processing device according to claim 1 ,
wherein the circuitry is further configured to initiate storage of the partial image information in an adaptation set of the metadata.

4. The information processing device according to claim 1 ,
wherein the partial image information is stored in a view point which is a descriptor type element of the adaptation set of the metadata.

5. The information processing device according to claim 1 ,
wherein the circuitry is further configured to initiate storage of the partial image information of each of a plurality of partial images in mutually different adaptation sets of the metadata and assign a respective bit stream of each of the plurality of partial images to a respective adaptation set of the mutually different adaptation sets.

6. The information processing device according to claim 1 ,
wherein the circuitry is further configured to initiate storage of the partial image information of each of the plurality of partial images in mutually different sub-representations belonging to one representation belonging to one adaptation set of the metadata and assign a respective bit stream of each of the plurality of partial images to a respective sub-representation of the mutually different sub-representations.

7. The information processing device according to claim 6 ,
wherein the partial image information includes information indicating that the respective bit stream exists under the respective sub-representation.

8. The information processing device according to claim 6 ,
wherein the respective bit stream of each of the plurality of partial images is stored in a TRACK of one MP4 file.

9. The information processing device according to claim 8 ,
wherein the circuitry is further configured to generate information indicating a location of data of the one MP4 file.

10. The information processing device according to claim 1 ,
wherein the partial image information includes information on a size of the whole image.

11. The information processing device according to claim 1 ,
wherein the at least one tile image comprises an HEVC tile image.

12. The information processing device according to claim 1 ,
wherein the partial image information includes
information indicating a number of partial images constituting the whole image,
identification information indicating whether or not sizes of the partial images are equal, and
information indicating a position and a size of each partial image when the sizes of the partial images are not equal.

13. An information processing method comprising:
generating metadata used for provision of a bit stream of a whole image and provision of a bit stream of a partial image that is part of the whole image; and
storing partial image information on the partial image in an adaptation set of the metadata,
wherein the partial image is composed of at least one tile image,
wherein the partial image information includes a view type (viewtype) indicating whether or not the partial image information is a partial image,
wherein the partial image information includes group identification information for identifying a group of partial images that can be displayed as one image, and
wherein the partial image information includes position information indicating a position of the partial image within the whole image.

14. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer, causes the computer to execute a method, the method comprising:
generating metadata used for provision of a bit stream of a whole image and provision of a bit stream of a partial image that is part of the whole image; and
storing partial image information on the partial image in an adaptation set of the metadata,
wherein the partial image is composed of at least one tile image,
wherein the partial image information includes a view type (viewtype) indicating whether or not the partial image information is a partial image,
wherein the partial image information includes group identification information for identifying a group of partial images that can be displayed as one image, and
wherein the partial image information includes position information indicating a position of the partial image within the whole image.
