  • Patent number: 10211997
    Abstract: 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.
