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 managing a bookmark item and a content item, the method performed by a server and comprising:

receiving, from a control device, a creating request for creating the bookmark item using a rendering state variable and a transporting state variable,

wherein the bookmark item is created and the created bookmark item includes a bookmark identifier (ID) and a content ID of the content item for associating the bookmark item with the content item, the rendering state variable, the transporting state variable and a service ID, and

wherein the content item indicates audio/video (AV) data to be bookmarked for reproduction by a media device and is updated to include the bookmark ID of the created bookmark item that is associated with the content item;

receiving, from the control device, a deleting request instructing the server to perform a bookmark deleting operation;

performing the bookmark deleting operation, wherein the bookmark deleting operation comprises;

deleting the bookmark item corresponding to the deleting request; and

updating the associated content item by removing the bookmark ID from the associated content item when the bookmark item is deleted,

wherein the bookmark item is used for recovering the rendering state variable and the transporting state variable associated with playback of the content item,

wherein the rendering state variable is associated with a rendering control service and includes at least audio volume or display luminance,

wherein the transporting state variable is associated with an AV transport service and includes at least presentation time,

wherein the service ID identifies the rendering control service and the AV transport service, and

wherein the content item is stored in the server.

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

3. A server for managing a bookmark item and a content item, the server comprising:

an interfacing device configured to at least transmit or receive data; and

a control device configured to;

receive, via the interface device, a creating request for creating the bookmark item using a rendering state variable and a transporting state variable,

wherein the bookmark item is created and the created bookmark item includes a bookmark identifier (ID) and a content ID of the content item for associating the bookmark item with the content item, the rendering state variable, the transporting state variable and a service ID, and

wherein the content item indicates audio/video (AV) data to be bookmarked for reproduction by a media device and is updated to include the bookmark ID of the created bookmark item that is associated with the content item; and

receive, via the interface unit, a deleting request from a controller, the deleting request instructing the server to perform a bookmark deleting operation; and

perform the bookmark deleting operation, wherein the bookmark deleting operation comprises;

deleting the bookmark item corresponding to the deleting request; and

updating the associated content item by removing the bookmark ID from the associated content item when the bookmark item is deleted,

wherein the bookmark item is used for recovering the rendering state variable and the transporting state variable associated with playback of the content item,

wherein the rendering state variable is associated with a rendering control service and includes at least audio volume or display luminance,

wherein the transporting state variable is associated with an AV transport service and includes at least presentation time, wherein the service ID identifies the rendering control service and the AV transport service, and wherein the content item is stored in the server.

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