Abstract
A second screen application operating on a client device presents a deduplicated listing of devices in a user interface, each listed device associated with one or more coupling protocols. A selection of a listed device is received via the user interface with which to participate in a video display session. Application status information is obtained from a control server for a first screen application of the selected device, the application status information indicating whether the first screen application is in an existing video display session with a second client device. A coupling methodology is determined based on the indicated application status and coupling protocols available to the client device and the one or more coupling protocols of the first screen application; and the client device couples to the first screen application via the determined coupling methodology.
