Abstract

A method and apparatus for managing bookmark information of a media server through a network based on the UPnP AV standard is disclosed. If a request for bookmarking a content item is made, a bookmark item is created and the created bookmark item is linked to the content item by adding the ID of the created bookmark item to the property information of the content item and recording the ID of the content item to be bookmarked in the created bookmark item.

Claims

1. A method for bookmarking a content item, the method performed by a server and comprising:

receiving a command for creating a bookmark item, wherein the bookmark item is associated with the content item and the bookmark item is used for recovering a rendering state variable and a transporting state variable associated with playback of the content item, the rendering state variable for rendering service of the content item and the transporting state variable for transporting service of the content item;

wherein the content item includes a content identifier (ID) for uniquely identifying the content item;

creating the bookmark item in response to the command, such that the bookmark item is separate from the content item; and

updating the content item in response to the command,

wherein the command comprises the rendering state variable, the transporting state variable, title, and the content identifier (ID), the title being a string type and the rendering state variable and the transporting state variable being written using a markup language,

wherein creating the bookmark item comprises;

recording the rendering state variable and the transporting state variable in the bookmark item,

recording a bookmark identifier (ID) in the bookmark item, the bookmark ID uniquely identifying the bookmark item, and

recording the content ID in the bookmark item for associating the bookmark item with the content item, and

wherein updating the content item comprises;

recording the same bookmark ID as the bookmark ID recorded in the created bookmark item for associating the content item with the bookmark item.

2. The method of claim 1, wherein the rendering state variable includes at least audio volume or display luminance.

3. The method of claim 1, wherein the bookmark ID is generated by the server.

4. The method of claim 1, wherein the command includes a container ID for assigning a location of the created bookmark item.

5. A server for bookmarking a content item, the server comprising:

an interface unit configured to receive a command for creating a bookmark item in order to bookmark the content item from an external device, and the bookmark item is used for recovering a rendering state variable and a transporting state variable associated with playback of the content item, the rendering state variable for rendering service of the content item and the transporting state variable for transporting service of the content item,

wherein the content item includes a content identifier (ID) for uniquely identifying the content item,

wherein the command includes the rendering state variable, the transporting state variable, a title, and the content ID, the title being a string type and the rendering state variable and the transporting state variable being a markup language; and

a controller configured to create the bookmark item in response to the command and to update the content item in response to the command, such that the bookmark item is separate from the content item,

wherein the created bookmark item comprises;

the rendering state variable and the transporting state variable,

a bookmark identifier (ID) for uniquely identifying the bookmark item, and

the content ID of the content item to associate the bookmark item with the content item,

wherein the updated content item comprises the same bookmark ID as the bookmark ID comprised in the created bookmark item for associating the content item with the bookmark item.

6. The server of claim 5, wherein the rendering state variable includes at least sound volume or luminance.

7. The server of claim 5, wherein the bookmark ID is generated by the server.

8. The server of claim 5, wherein the command includes a container ID for assigning the location of the created bookmark item.
