Abstract
Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. In a boundary region between first and second broadcast stations in which a receiver can pick up signals from both stations, a primary tuner presents a demanded service while a secondary tuner scans for duplicate transmissions of the service and tunes to it if found. When the primary tuner loses signal, it tunes to the frequency of the secondary tuner and acquires any missing NRT data recorded from the secondary tuner prior to the handover.
