Abstract

A protocol and related techniques and platforms allow vendors to selectably extend the Media Transport Protocol (MTP), or other defined protocols to implement vendor-specific commands, data fields, instructions and other extension sets. According to embodiments of the invention in one regard, one or more extension space may be utilized to derive independent extension sets, in part by separating the extension space according to a unique identifier assigned to or associated with a given vendor. In embodiments that unique identifier may be or include an Internet DNS (Domain Name System) domain name, or other extension set name or identifier. According to the invention in one regard, because a DNS domain name may be independently registered and secured by participating vendors or manufacturers and by definition uniquely assigned, the separation of vendor extension sets by that type of name may be automatic and free from conflict. Vendors or manufacturers, such as makers of digital cameras, digital video cameras, audio players such as MP3 or other players, software vendors or others may therefore freely design extensions to the Media Transport Protocol or other protocols, without a need to clear those extensions with a standards body and with confidence that their commands, data fields and other extensions may be free from overlap with that of other manufacturers.

Claims

1. A system for initiating operations from an extension set to a protocol, comprising:

a communications interface communicating with a device;

an extension set extending operations of a transport protocol, the extension set being identified by a unique identifier associated with the extended operations; and

a control module, the control module communicating with the communications interface and the extension set to control the device using the extended operations of the extension set.

2. A system according to claim 1, wherein the device comprises at least one of an audio player, an audio recorder, a video player, a video recorder, a personal digital assistant, a cellular telephone, a global positioning device, an event recording device, a portable storage device and a remotely controlled device.

3. A system according to claim 1, wherein the control module is hosted in a client.

4. A system according to claim 3, wherein the client comprises a computer.

5. A system according to claim 1, wherein the extension set comprises at least one of extended commands, extended operations and extended data fields.

6. A system according to claim 1, wherein the unique identifier comprises a Domain Name System domain name.

7. A system according to claim 1, wherein the unique identifier is encoded within an extension space of the transport protocol.

8. A system according to claim 7, wherein the extension space comprises a restricted extension space.

9. A system according to claim 1, wherein the unique identifier is encoded within an unused or known safe portion of the transport protocol.

10. A system according to claim 1, wherein the transport protocol comprises the Media Transport Protocol.

11. A system according to claim 1, wherein the extension set identified by the unique identifier automatically does not conflict with an extension set associated with another unique identifier.

12. A system according to claim 11, wherein the extension set is independently defined from the extension set associated with the other unique identifier.

13. A system according to claim 1, wherein the extension set is downloadable via a remote data store.

14. A device, the device being configured to execute operations from an extension set to a protocol, comprising:

a communications interface to communicate with a client; and

a processor, the processor communicating with the communications interface to initiate operations of an extension set to a transport protocol based on a unique identifier associated with the operations.

15. A device according to claim 14, wherein the device comprises at least one of an audio player, an audio recorder, a video player, a video recorder, a personal digital assistant, a cellular telephone, a global positioning device, an event recording device, a portable storage device and a remotely controlled device.

16. A device according to claim 15, wherein the client comprises a computer.

17. A device according to claim 14, wherein the extension set comprises at least one of extended commands, extended operations and extended data fields.

18. A device according to claim 14, wherein the unique identifier comprises a Domain Name System domain name.

19. A device according to claim 14, wherein the unique identifier is encoded within an extension space of the transport protocol.

20. A device according to claim 14, wherein the transport protocol comprises the Media Transport Protocol.

21. A device according to claim 14, wherein the extension set identified by the unique identifier automatically does not conflict with an extension set associated with a unique identifier associated with another device.

22. A method for processing operations of an extension set to a protocol, comprising:

communicating with a device;

accessing an extension set, the extension set comprising extended operations of a transport protocol, the extension set being identified by a unique identifier associated with the extended operations; and

controlling the device using the extended operations of the extension set.

23. A method according to claim 22, wherein the device comprises at least one of an audio player, an audio recorder, a video player, a video recorder, a personal digital assistant, a cellular telephone, a global positioning device, an event recording device, a portable storage device and a remotely controlled device.

24. A method according to claim 22, wherein the controlling is executed in a client.

25. A method according to claim 24, wherein the client comprises a computer.

26. A method according to claim 22, wherein the extension set comprises at least one of extended commands, extended operations and extended data fields.

27. A method according to claim 22, wherein the unique identifier comprises a Domain Name System domain name.

28. A method according to claim 22, wherein the unique identifier is encoded within an extension space.

29. A method according to claim 28, wherein the extension space comprises a restricted extension space.

30. A method according to claim 22, wherein the unique identifier is encoded within an unused or known safe portion of the transport protocol.

31. A method according to claim 22, wherein the transport protocol comprises the Media Transport Protocol.

32. A method according to claim 22, wherein the extension set identified by the unique identifier automatically does not conflict with an extension set associated with another unique identifier.

33. A selectable extension set to a transport protocol, comprising:

a unique identifier field, the unique identifier field being associated with a device; and

an extension set, the extension set extending the operations of a transport protocol in the device, the extension set being identified by the unique identifier associated with the extended operations.

34. A selectable extension set according to claim 33, wherein the device comprises at least one of an audio player, an audio recorder, a video player, a video recorder, a personal digital assistant, a cellular telephone, a global positioning device, an event recording device, a portable storage device and a remotely controlled device.

35. A selectable extension set according to claim 33, wherein the extension set is activated via a client.

36. A selectable extension set according to claim 35, wherein the client comprises a computer.

37. A selectable extension set according to claim 33, wherein the extension set comprises at least one of extended commands, extended operations and extended data fields.
