Abstract

A method for delivering content playback related information between devices comprising gathering state information from at least one service by invoking an action to the at least one service and storing the gathered state information in a device. A system for delivering content playback related information includes a server for storing content, a device including at least one service, and a control point for gathering state information from the at least one service by invoking an action to the device and storing the gathered state information in the server.

Claims

1-20. -20. (canceled)

21. A method for delivering content playback related information between devices, the method comprising:

gathering state information from at least one service by invoking an action to the at least one service; and

storing the gathered state information in a device.

22. The method of claim 21, wherein the stored state information is used as control information for resuming playback of content from a playback-stopped position.

23. The method of claim 21, wherein the stored state information includes values set while content is rendered.

24. The method of claim 21, wherein the at least one service is related to playback of content.

25. The method of claim 21, wherein the at least one service comprises at least one of:

an AVTransport service; and

a Rendering Control service.

26. The method of claim 21, further comprising setting values of the stored state information to the at least one service, wherein the at least one service is designated for playback of content via a second action.

27. The method of claim 26, wherein the at least one service designated for playback of content comprises at least one of:

an AVTransport service; and

a Rendering Control service.

28. The method of claim 24, further comprising:

setting values of the stored state information to the at least one service, wherein the at least one service is designated for playback of content via a second action;

wherein a Rendering Control service included in the at least one service related to playback of content and a Rendering control service included in the at least one service designated for playback of content are included in separate devices.

29. The method of claim 26, wherein the action comprises a Get string and the second action comprises a Set string.

30. The method of claim 26, wherein the gathering step comprises obtaining state information that is carried on an output argument of the action by the at least one service related to playback of content in response to the action, and the setting step comprises carrying the obtained state information on an input argument of the second action to deliver to the at least one service designated for playback of content.

31. The method of claim 26, further comprising playing the content from a stopped position, wherein the playing is conducted by the at least one service designated for playback of content.

32. The method of claim 21, wherein the storing step stores the gathered state information in a device storing content.

33. The method of claim 21, wherein the gathering step gathers state information when playback of content is stopped.

34. A system for delivering content playback related information, the system comprising:

a server for storing content;

a device including at least one service; and

a control point for gathering state information from the at least one service by invoking an action to the device and storing the gathered state information in the server.

36. The system of claim 34, wherein the stored state information includes values set while the content is rendered.

37. The system of claim 34, wherein the at least one service is related to playback of the content.

38. The system of claim 37, wherein the at least one service comprises at least one of:

an AVTransport service; and

a Rendering Control service.

39. The system of claim 38, wherein the server includes the AVTransport service and the device includes the Rendering Control service.

40. The system of claim 38, wherein the device includes both the AVTransport service and the Rendering Control service.

41. The system of claim 34, wherein the control point sets values of the stored state information to at least one service, wherein the at least one service is designated for playback of content via a second action.

42. The system of claim 41, wherein the action comprises a Get string and the second action comprises a Set string.

43. The system of claim 41, wherein the control point invokes the second action to the device.

44. The method of claim 34, wherein the control point gathers the state when playback of content is stopped.

35. The system of claim 343 wherein the stored state information is used as control information for resuming playback of the content from a playback-stopped position.
