INTEROPERABILITY OF DISCOVERY AND CONNECTION PROTOCOLS BETWEEN CLIENT DEVICES AND FIRST SCREEN DEVICES

A second screen device discovers a first screen application operating on the first screen device and a plurality of coupling protocols available to connect to the first screen device. The second screen device provides a device list based on the discovering, the device list including a plurality of entries each associated with the first screen application and a respective coupling protocol of the plurality of coupling protocols. The second screen device obtains pairing information for the first screen application from a control server. The second screen device updates the device list using the pairing information from the control server. The second screen device performs device deduplication using the updated device list to generate a deduplicated entry for the first screen application, and presents the deduplicated entry for the first screen application in a user interface.
