AUTOMATIC DISCOVERY AND MIRRORING OF SERVER-CLIENT REMOTE USER INTERFACE (RUI) SESSION ON A COMPANION DEVICE AND SYNCHRONOUSLY CONTROLLING BOTH SESSIONS USING RUI ON COMPANION DEVICE

摘要

A server sends to a video device such as a TV a remote user interface (RUI) that is presented on the TV and manipulable to send control commands back to the server. A companion device such as a tablet computer discovers the RUI session and is provided by the server with its own RUI, which mirrors that on the TV, modified as appropriate for the screen of the companion device. The server maintains the two RUIs synchronized such that the RUI on the companion mirrors the RUI on the TV.
