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 lower level signaling PLP is used to identify frequencies duplicatively carrying the same service and then higher level PLPs are activated for each duplicate to determine a channel quality metric for identifying the best frequency to receive the service on, which is sent from both stations.
