Abstract

The present invention relates to a bookmark of media contents, more particularly to method and apparatus for supporting mobility of bookmarks set on media contents. The media content playing method according to the present invention stores bookmark information in agency means, e.g., mobile control point (CP) or a connectable memory stick if a bookmark is set on a first media content, and plays a second media content, that is identical to the first, from the same position with the bookmarked position on the first media content, based on the bookmark information stored in the agency means.

Claims

1. A method for playing a first media object and a second media object that have the same content, comprising the steps of:

(a) storing bookmark information in agency means if a bookmark is set on the first media object; and

(b) playing the second media object from a position where the bookmark is set on the first media object, based on the bookmark information stored in the agency means.

2. The method set forth in claim 1, wherein the agency means is one among a mobile apparatus that can wirelessly access networks, an attachable memory attached to an arbitrary apparatus, and a general-purpose server connected to a local network that can be accessed through a public network.

3. The method set forth in claim 1, wherein the first media object and the second media objects are stored separately in apparatuses existing on different local networks.

4. The method set forth in claim 1, wherein the bookmark information comprises metadata of the bookmarked media object, information on the status of presentation of the media object, and identification information that is uniquely assigned to the bookmark.

5. The method set forth in claim 4, wherein the meta data includes the identifier and title of the bookmarked media object.

6. The method set forth in claim 5, wherein the step (b) finds the second media object from a plurality of media objects, based on object identifier or title contained in the bookmark information.

7. The method set forth in claim 5, wherein the step (b) includes steps of sequentially requesting an action for setting the bookmarked position to the position where the streaming of the found media object starts and a play action for starting the streaming operation to the apparatus in which the found media object is stored and/or the apparatus that will render the data of the media object.

8. The method set forth in claim 4, wherein the information on the status of presentation includes status variables for data rendering of the bookmarked media object and status variables for managing data transport points.

9. The method set forth in claim 1, wherein the bookmark on the first media object is set automatically on a position where the playback of the first media object is stopped.

10. The method set forth in claim 1, wherein the bookmark on the first media object is set on a position of the first media object where user'"'"'s request is made.

11. A networked apparatus, comprising:

a first device in which a first media object is stored;

a second device in which a second media object of the same content with the first media object is stored; and

agency means for storing bookmark information if a bookmark is set on the first media object,

wherein the agency means or a third device that can access the second device plays the second media object from a position where the bookmark is set on the first media object, based on the stored bookmark information.

12. The apparatus set forth in claim 11, wherein the agency means is one among a mobile apparatus that can wirelessly access networks, an attachable memory attached to an arbitrary apparatus, and a general-purpose server connected to the local network where the first apparatus exists.

13. The apparatus set forth in claim 11, wherein the first device and the second device are connected to local networks separated from each other.

14. The apparatus set forth in claim 11, wherein the bookmark information comprises metadata of the bookmarked media object, information on the status of presentation of the media object, and identification information that is uniquely assigned to the bookmark.
