A method and apparatus for playing back a scene using Universal Plug and Play (UPnP). A control point sends a request for a scene to be played back to a media server that stores Audio/Video (AV) content and receives the scene to be played back from the media server in response to the request. The control point receives information about supportable protocol and file format from a media renderer that will play back content, and determines a content resource, a protocol and a file format to be used for playback based on the information. The control point composes a scene to be played back based on the received scenes. The media renderer plays back the composed scene.

Various embodiments relate to a cloud-based temporary app management system. In one aspect of the invention, a cloud service provides a temporary app from a vendor. The temporary app is a mobile application that is temporarily accessible on a mobile device when a designated event (e.g. a change in the location or surroundings of the mobile device, a particular type of data stored in the mobile device, etc.) is detected by a mobile device. The cloud service receives event information from the mobile device. The event information indicates an event detected by the mobile device. The cloud service then determines whether to make the temporary app accessible on the mobile device based on an analysis of the designated event and the event information received from the mobile device.

Temporary applications for mobile devices

In a first embodiment of the present invention, a method for performing home networking media transport negotiation in a home network is provided, the method comprising: issuing a browse command on a content directory service in the home network to locate a custom resource element; and issuing an action to a media renderer in the home network to set a location of a media server to serve the item, wherein the issuing includes passing item metadata stored in the custom resource element, thus enabling the media renderer to negotiate directly with the media server while conveying detailed information about capabilities of the media renderer.

Home network media transport negotiation

In a first embodiment of the present invention, a method for operating a presence server in a home network is provided, the method comprising: receiving a request for presence information; sending an event notification to all subscribed control points informing them of the request for presence information; receiving an action from one of the subscribed control points accepting or rejecting the request for presence information; and if the action received from the one of the subscribed control points accepts the request for presence information, causing presence information regarding the one of the subscribed control points to be sent to the entity that sent the request for presence information.

Enabling presence information access and authorization for home network telephony

In a first embodiment of the present invention, a method for operating a user agent on a first device is provided, comprising: discovering, using a home networking protocol, a second device, wherein the second device includes a user input mechanism; retrieving information regarding the user input mechanism from the second device using the home networking protocol; determining whether to accept the connection based on the information regarding the user input mechanism; when it is determined to accept the connection, negotiating an out-of-band connection in a protocol other than the home networking protocol with the second device; receiving input command events from the second device via the out-of-band connection; and executing the input command events at the user agent to control an aspect of the first device.

Remote input devices

In a first embodiment of the present invention, a method for operating a remote user interface (UI) client is provided, the method comprising: establishing a first connection with a UI server; receiving a document over the first connection; closing the first connection; running the document, wherein the document contains first instructions on how to operate a user interface and second instructions on establishing a persistent connection with the UI server; and establishing a second connection with the UI server based on the second instructions.

Remote user interface cooperative application

In a first embodiment of the present invention, a method is provided comprising: creating a temporary home network electronic program guide object for a television program currently stored in a time-shift buffer of a home network-enabled device; and storing an identifier for the temporary home network electronic program guide object in an object for a channel.
