Abstract

Disclosed are a UPnP-based media contents reproducing system and a method thereof capable of fast and consecutively reproducing media contents reproduced by a first control point in another space by a second control point by informing state information of the media contents reproduced by the first control point to the second control point. The media contents reproducing system comprises a media server; a media renderer; and a first control point for controlling the media server and the media renderer, and transmitting rendering state information of the media renderer to the second control point.

Claims

1-20. -20. (canceled)

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

obtaining state information from at least one service;

invoking an action to a device to store the state information in the device, wherein the state information is included in the action as an input argument; and

storing the state information in the device according to the action.

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

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

an AVTransport service; and

a Rendering Control service.

24. The method of claim 21, wherein the stored state information is used as control information for late playback of a content from a position where playback of the content is stopped.

25. The method of claim 21, wherein the device includes the at least one service.

26. 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 controlling the server and the device, wherein the control point;

obtains state information from the at least one service; and

invokes an action to the server to store the state information in the server,

wherein the state information is included in the action as an input argument.

27. The system of claim 26, wherein the server stores the state information according the action.

28. The system of claim 26, wherein the at least one service is related to playback of the content.

29. The system of claim 26, wherein the at least one service comprises at least one of:

an AVTransport service; and

a Rendering Control service.

30. The system of claim 29, wherein the server includes the AVTransport service and the device includes the Rendering Control service.

31. The system of claim 29, wherein the device includes both the AVTransport service and the Rendering Control service.

32. The system of claim 27, wherein the state information stored in the server is used as control information for late playback of the content from a position where playback of the content is stopped.

33. The system of claim 27, further comprising a second control point for reading the state information stored in the server and setting the read state information to a second device.

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

invoking an action to a device to store state information in the device, wherein the state information is included in the action as an input argument, and the state information is obtained from at least one service.

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

36. The method of claim 34, wherein the at least one service comprises at least one of:

an AVTransport service; and

a Rendering Control service.

37. The method of claim 34, wherein the stored state information is used as control information for late playback of a content from a position where playback of the content is stopped.

38. The method of claim 34, wherein the device includes the at least one service.
