  • Patent number: 10298526
    Abstract: Embodiments are directed towards multi-level entity classification. An object associated with an entity is received. In one embodiment the object comprises and email and the entity comprises the IP address of a sending email server. If the entity has already been classified, as indicated by an entity classification cache, then a corresponding action is taken on the object. However, if the entity has not been classified, the entity is submitted to a fast classifier for classification. A feature collector concurrently fetches available features, including fast features and full features. The fast classifier classifies the entity based on the fast features, storing the result in the entity classification cache. Subsequent objects associated with the entity are processed based on the cached result of the fast classifier. Then, a full classifier classifies the entity based on at least the full features, storing the result in the entity classification cache.

  • 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.
