Method and apparatus for media scene description

1. A method of managing media storage and delivery, the method being implemented by at least one processor and comprising:

obtaining, by a media access function (MAF), a Graphics Language Transmission Format (glTF) file corresponding to a scene;

identifying a pointer in the glTF file that points to binary data included in the glTF file;

determining, based on the binary data included in the glTF file, that the glTF file has a Concise Binary Object Representation (CBOR) format;

converting the glTF file into a converted glTF file having a JavaScript Object Notation (JSON) format using a first CBOR parser function implemented by the MAF; and

obtaining media content corresponding to the scene based on the converted glTF file.

2. The method of claim 1 , wherein the converted glTF file having the JSON format is larger than the glTF file having the CBOR format.

3. The method of claim 1 , wherein the MAF is included in a Moving Picture Experts Group (MPEG) scene description architecture.

4. The method of claim 1 , wherein the first CBOR parser function is implemented using an application programming interface associated with the MAF.

5. The method of claim 1 , further comprising:

re-converting the converted glTF file into a re-converted glTF file having the CBOR format using a JSON parser function implemented by the MAF; and

storing the re-converted glTF file in at least one of a local storage or a cache.

6. The method of claim 5 , wherein the re-converted glTF file having the CBOR format is smaller than the converted glTF file having the JSON format.

7. The method of claim 5 , wherein the JSON parser function is implemented using an application programming interface associated with the MAF.

8. A device for managing media storage and delivery, the device comprising:

at least one memory configured to store program code; and

at least one processor configured to read the program code and operate as instructed by the program code, the program code including:

first obtaining code configured to cause the at least one processor to obtain, by a media access function (MAF), a Graphics Language Transmission Format (glTF) file corresponding to a scene;

identifying code configured to cause the at least one processor to identify a pointer in the glTF file that points to binary data included in the glTF file;

first determining code configured to cause the at least one processor to determine, based on the binary data included in the glTF file, that the glTF file has a Concise Binary Object Representation (CBOR) format;

first converting code configured to cause the at least one processor to convert the glTF file into a converted glTF file having a JavaScript Object Notation (JSON) format using a first CBOR parser function implemented by the MAF; and

second obtaining code configured to cause the at least one processor to obtain media content corresponding to the scene based on the converted glTF file.

9. The device of claim 8 , wherein the converted glTF file having the JSON format is larger than the glTF file having the CBOR format.

10. The device of claim 8 , wherein the MAF is included in a Moving Picture Experts Group (MPEG) scene description architecture.

11. The device of claim 8 , wherein the first CBOR parser function is implemented using an application programming interface associated with the MAF.

12. The device of claim 8 , wherein the program code further includes:

re-converting code configured to cause the at least one processor to re-convert the converted glTF file into a re-converted glTF file having the CBOR format using a JSON parser function implemented by the MAF; and

storing code configured to cause the at least one processor to store the re-converted glTF file in at least one of a local storage or a cache.

13. The device of claim 12 , wherein the re-converted glTF file having the CBOR format is smaller than the converted glTF file having the JSON format.

14. The device of claim 12 , wherein the JSON parser function is implemented using an application programming interface associated with the MAF.

15. A non-transitory computer-readable medium storing instructions, the instructions comprising: one or more instructions that, when executed by at least one processor of a device for managing media storage and delivery, are configured to cause the at least one processor to:

obtain, by a media access function (MAF), a Graphics Language Transmission Format (glTF) file corresponding to a scene;

identify a pointer in the glTF file that points to binary data included in the glTF file;

determine, based on the binary data included in the glTF file, that the glTF file has a Concise Binary Object Representation (CBOR) format;

convert the glTF file into a converted glTF file having a JavaScript Object Notation (JSON) format using a first CBOR parser function implemented by the MAF; and

obtain media content corresponding to the scene based on the converted glTF file.

16. The non-transitory computer-readable medium of claim 15 , wherein the converted glTF file having the JSON format is larger than the glTF file having the CBOR format.

17. The non-transitory computer-readable medium of claim 15 , wherein the first CBOR parser function is implemented using an application programming interface associated with the MAF.

18. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions are further configured to cause the at least one processor to:

re-convert the converted glTF file into a re-converted glTF file having the CBOR format using a JSON parser function implemented by the MAF; and

store the re-converted glTF file in at least one of a local storage or a cache.

19. The non-transitory computer-readable medium of claim 18 , wherein the re-converted glTF file having the CBOR format is smaller than the converted glTF file having the JSON format.

20. The non-transitory computer-readable medium of claim 18 , wherein the JSON parser function is implemented using an application programming interface associated with the MAF.
