Abstract

One or more vendor extensions that may be communicated to and/or from a device that may communicate via media transfer protocol (MTP) may be specified within an extension of the MTP. The vendor extension may comprise vendor specific information such as proprietary supported features. Vendor extensions may be indicated as a device property and may be communicated to another device during initiation of communication. Supported vendor extensions may be specified in an MTP DevicePropDesc dataset as a response to a request such as a MTP GetDevicePropDesc operation. Alternatively, data from a current value field of an MTP DevicePropDesc dataset may be returned in response to a GetDevicePropValue operation. An MTP SetDevicePropValue operation may be utilized for selecting a vendor extension. However, the selection may be accepted or rejected by a device. An event may be issued to other devices when a change of vendor extension has occurred.

Claims

1. A method for communicating multimedia information, the method comprising:

specifying, by a circuitry, information associated with a vendor extension of a media transfer protocol (MTP), said information including features enabled by said vendor extension;

alerting, by said circuitry, a device of said information to allow said device to accept or reject said vendor extension, said device configured to communicate via said MTP, and said alerting occurring via an MTP dataset that includes device properties and an array of unsigned integers in a string indicating said vendor extension and at least one other extension said device supports; and

transmitting, by said circuitry, said vendor extension that said device accepts.

2. The method according to claim 1, comprising indicating said information as a device property within said vendor extension of said MTP.

3. The method according to claim 1, comprising communicating said information to another device when said device initiates communication with said another device.

4. The method according to claim 1, comprising specifying said information in response to a request.

5. The method according to claim 4, wherein said request comprises an MTP operation configured to retrieve said device properties.

6. The method according to claim 4, wherein said response comprises said MTP dataset including said device properties.

7. The method according to claim 4, wherein said request comprises an MTP operation configured to retrieve device property values.

8. The method according to claim 4, wherein said response comprises data from a current value field of said MTP dataset including said device properties.

9. The method according to claim 1, comprising one or both of:

selecting said vendor extension for communicating to or from said device via an MTP operation configured to set device property values; and

communicating to or from said device based on said information.

10. The method according to claim 1, comprising issuing an event to indicate when a change to said vendor extension occurs.

11. A system for communicating multimedia information, the system comprising:

circuitry is configured to specify information associated with a vendor extension of a media transfer protocol (MTP), said information including features enabled by said vendor extension;

said circuitry is configured to alert a device of said information to allow said device to accept or reject said vendor extension, said device configured to communicate via said MTP, and said alerting occurring via an MTP dataset that includes device properties and an array of unsigned integers in a string indicating said vendor extension and at least one other vender extension said device supports; and

said circuitry is configured to communicate said vendor extension that said device accepts.

12. The system according to claim 11, wherein said circuitry is configured to indicate said information as a device property within said vendor extension of said MTP.

13. The system according to claim 11, wherein said circuitry is configured to communicate said information to another device when said device initiates communication with said another device.

14. The system according to claim 11, wherein said circuitry is configured to specify said information in response to a request.

15. The system according to claim 14, wherein said request comprises an MTP operation configured to retrieve said device properties.

16. The system according to claim 14, wherein said response comprises said MTP dataset including said device properties.

17. The system according to claim 14, wherein said request comprises an MTP operation configured to retrieve device property values.

18. The system according to claim 14, wherein said response comprises data from a current value field of said MTP dataset including said device properties.

19. The system according to claim 11, wherein said circuitry is configured to select said vendor extension for communicating to or from said device via an MTP operation configured to set device property values;

and

said circuitry is configured to communicate to or from said device based on said information.

20. The system according to claim 11, wherein said circuitry is configured to issue an event to indicate when a change to said vendor extension occurs.

21. A non-transitory machine-readable storage having stored thereon, a computer program having at least one code section, the at least one code section being executable by a machine, the machine readable storage comprising:

instructions to specify information associated with a vendor extension of a media transfer protocol (MTP), said information including features enabled by said vendor extension;

instructions to alert a device of said information to allow said device to accept or reject said vendor extension, said device configured to communicate via said MTP, and said alerting occurring via an MTP dataset that includes device properties and an array of unsigned integers in a string indicating said vendor extension and at least one other vender extension said device supports; and

instructions to communicate said vendor extension that said device accepts.

22. The non-transitory machine-readable storage according to claim 21, wherein the machine-readable storage further comprises instructions to indicate said information as a device property within said vendor extension of said MTP.

23. The non-transitory machine-readable storage according to claim 21, wherein the machine-readable storage further comprises instructions to communicate said information to another device when said device initiates communication with said another device.

24. The non-transitory machine-readable storage according to claim 21, wherein the machine-readable storage further comprises instructions to specify said information in response to a request.

25. The non-transitory machine-readable storage according to claim 24, wherein said request comprises an MTP operation configured to retrieve said device properties.

26. The non-transitory machine-readable storage according to claim 24, wherein said response comprises said MTP dataset including said device properties.

27. The non-transitory machine-readable storage according to claim 24, wherein said request comprises an MTP operation configured to retrieve device property values.

28. The non-transitory machine-readable storage according to claim 24, wherein said response comprises data from a current value field of said MTP dataset including said device properties.

29. The non-transitory machine-readable storage according to claim 21, wherein the machine-readable storage further comprises instructions to perform one or both of:

selecting said vendor extension for communicating to or from said device via an MTP operation configured to set device property values; and

communicating to or from said device based on said information.

30. The non-transitory machine-readable storage according to claim 21, wherein the machine-readable storage further comprises instructions to issue an event to indicate when a change to said vendor extension occurs.
