More Information
Summary:A real-time media stream, multicast by a remote computing system, is received by an on-board system of a vehicle. While being received, the real-time media stream is packaged into time-delineated media segments that are input to a buffer. One or more missing segments are identified after a signal loss event (e.g., a satellite handoff), and a request for the missing segment(s) is/are caused to be sent to the remote computing system. The missing segment(s) is/are received from the remote computing system via a unicast transmission, and inserted into the buffer in sequence with the time-delineated media segments. The buffered real-time media stream, including the inserted segment(s), is caused to be provided to one or more electronic devices on-board the vehicle. In this manner, the real-time media stream may be seamlessly delivered to the on-board electronic device(s) despite a loss of connectivity due to the signal loss event.
