Abstract
An electronic device, method, and computer program product provide an asynchronous quick connection or reconnection between wireless connecting devices for low-latency transitions in presentation of content to a user. A first device transmits an out-of-band frame sync signal to a second device to prompt the second device to synchronize clocks with the first device and to one of: (i) connect; and (ii) reconnect an over-the-air (OTA) communication session with the first device. First and second devices establish the OTA communication session. The establishment is expedited by the out-of-band frame sync signal. First device transmits output data, via the in-band OTA session, by the first device to the second device to present the output data on a second user output device of the second device.
