Information processing apparatus, information processing method, and program
There are provided an information processing apparatus, an information processing method, and a program. The information processing apparatus includes a generating unit configured to generate a content file including object selection information for selecting object audio data in accordance with a display state of an image, in which the generating unit stores the object selection information in a metadata file included in the content file.
1. An information processing apparatus comprising:
a generating unit configured to generate a content file including object selection information for selecting object audio data in accordance with a display state of an image,
wherein the generating unit stores the object selection information in a metadata file included in the content file,
wherein the object selection information includes angle of view information regarding an angle of view of a clipped image or an angle of view upon viewing with respect to a displayed image,
wherein the angle of view information includes information of a range of magnification with respect to a reference angle of view, and
wherein the generating unit is implemented via at least one processor.
2. The information processing apparatus according to claim 1 , wherein the metadata file is a file for which standards are defined in ISO/IEC 14496-12.
3. The information processing apparatus according to claim 2 , wherein the object selection information is stored in sampleEntry in a moov box of the metadata file.
4. The information processing apparatus according to claim 3 , wherein the object selection information is stored in objectSelectionMetadataConfigurationBox included in the sampleEntry.
5. The information processing apparatus according to claim 4 , wherein the object selection information includes audio file access information for accessing an audio file in which the object audio data is stored.
6. The information processing apparatus according to claim 5 , wherein the audio file access information includes streamID.
7. The information processing apparatus according to claim 1 , wherein the object selection information includes direction information regarding a direction of a clipped image.
8. The information processing apparatus according to claim 7 , wherein the direction information includes information of an angle in a horizontal direction and information of an angle in a vertical direction.
9. The information processing apparatus according to claim 8 , wherein the direction information further includes information of a range of an angle from a clipping direction vector.
10. The information processing apparatus according to claim 7 , wherein the direction information includes information of a range of an angle in a horizontal direction and information of a range of an angle in a vertical direction.
11. The information processing apparatus according to claim 1 , wherein the angle of view information includes information of a range of a horizontal angle of view and information of a range of a vertical angle of view.
12. The information processing apparatus according to claim 1 , wherein the object selection information further includes angle information regarding an angle between the two objects.
13. The information processing apparatus according to claim 1 , wherein the object selection information includes information regarding the object audio data to be utilized.
14. An information processing apparatus comprising:
a generating unit configured to generate a content file including object selection information for selecting object audio data in accordance with a display state of an image,
wherein the generating unit stores the object selection information in a metadata file included in the content file,
wherein the object selection information includes position information of two objects between which an angle is to be calculated, and
wherein the generating unit is implemented via at least one processor.
15. A reproduction apparatus comprising:
circuitry configured to initiate reproduction based on a content file including object selection information for selecting object audio data in accordance with a display state of an image,
wherein the object selection information is stored in a metadata file included in the content file,
wherein the object selection information includes angle of view information regarding an angle of view of a clipped image or an angle of view upon viewing with respect to a displayed image, and
wherein the angle of view information includes information of a range of magnification with respect to a reference angle of view.
16. A reproduction apparatus comprising:
circuitry configured to initiate reproduction based on a content file including object selection information for selecting object audio data in accordance with a display state of an image,
wherein the object selection information is stored in a metadata file included in the content file,
wherein the object selection information includes position information of two objects between which an angle is to be calculated.
