Abstract

A method and apparatus of using pause time information on media content under an UPnP environment. A method of using pause time information on media content under UPnP environment includes: transmitting the media content to a first media renderer; receiving a signal that stops the media content from being transmitted; stopping transmitting the media content and adding the pause time information on the media content to the media content or metadata that stores information on the media content; and transmitting the media content from a pause point of time if the first media renderer or a second media renderer requests transmission of the media content

Claims

1. A method of using pause time information on media content under a UPnP environment, comprising:

transmitting the media content to a first media renderer;

receiving a signal that stops the media content from being transmitted;

stopping transmitting the media content and adding the pause time information on the media content to the media content or metadata that stores information on the media content; and

retransmitting the media content based on the pause time information if the first media renderer or a second media renderer requests transmission of the media content.

2. The method of claim 1, further comprising:

adding information on a first user, who requested a transmission of the media content through the first media renderer, to the media content or metadata,

wherein, in the retransmitting of the media content, if a second user that requests transmission of the media content is the same as the first user, the media content is transmitted from a pause point of time.

3. The method of claim 1,

wherein the stopping of the transmission of the media content and the adding of the pause time information on the media content includes:

correcting the metadata with respect to the media content by means of a content directory service “

CDS”

.

4. The method of claim 1,

wherein the adding of the pause time information to the media content is adding the pause time information to an XML document that stores URI information on the media content.

5. The method of claim 4,

wherein, in the adding of the pause time information, a new information including resource information and the pause time information is added within an item including information on the media content.

6. The method of claim 4,

wherein, in the adding of the pause time information, the pause time information is added as attribute information in a ‘

res’

region within an item including information on the media content, the ‘

res’

region including resource information.

7. The method of claim 4,

wherein, in the adding of the pause time information, a new item including the pause time information is added within an item including information on the media content.

8. The method of claim 1, further comprising:

receiving a decision result on whether the media content is to be transmitted from a pause point of time or from another point of time, before the retransmitting of the media content.

9. A method of using pause time information on media content under a UPnP environment, comprising:

playing back the media content;

stopping playing back of the media content;

adding the pause time information on the media content to the media content or metadata that stores information on the media content; and

resuming playing back the media content based on the pause time information when the media content needs to be played back again.

10. The method of claim 9, further comprising:

adding information on a first user, who has played back the media content, to the metadata,

wherein, in the resuming playing back of the media content, if a second user that requests playback of the media content is the same as the first user, the media content is played back from a pause point of time.

11. The method of claim 9,

wherein the adding of the pause time information on the media content includes:

revising the metadata by use of a control point separate from a media renderer for playing back the media content.

12. The method of claim 9,

wherein the adding of the pause time information on the media content is adding the pause time information to an XML document that stores URI information on the media content.

13. The method of claim 12,

wherein, in the adding of the pause time information, a new information including resource information and the pause time information on the media content is added within an item including information on the media content.

14. The method of claim 12,

wherein, in the adding of the pause time information, the pause time information is added as attribute information in a “

res”

region within an item including information on the media content, the “

res”

region including resource information.

15. The method of claim 12,

wherein, in the adding of the pause time information, a new information including the pause time information on the media content is added within an item including information on the media content.

16. The method of claim 9, further comprising:

receiving a decision result on whether the media content is to be played back from a pause point of time or from another point of time, before the resuming playing back of the media content.

17. An apparatus for playing media content, comprising:

a media server that stores the media content;

a first media renderer that plays back the media content and is configured to store pause information in the media content or metadata related to the media content; and

a control point that provides input to the first media renderer and the media server from a first user,

wherein if the first user requests that the media content be played, the control point sends a play input to the media renderer and the media server transmits the media content to the media renderer,

wherein if the first user requests that the media content be paused, the control point transmits a pause input and the media server records pause information on the media content or metadata related to the media content.

18. The apparatus for playing media content according to claim 17, wherein the control point transmits the pause input to the media renderer that transmits the pause input to the media server.

19. The apparatus for playing media content according to claim 17, wherein the control point transmits the pause input directly to the media server.

20. The apparatus for playing media content according to claim 17, wherein the pause information is recorded in at least one of an XML document, the metadata, and the media content.
