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 (302) between first and second broadcast stations in which a receiver (300) can pick up signals from both stations (304), a lower level signaling PLP is used (810) to identify a channel quality metric for identifying the best frequency to receive a broadcast service on which is sent from both stations.

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. An ATSC 3.0 service list table (SLT) (240) contains correlations between service IDs and frequencies so that a receiver (300) receiving duplicate services on different frequencies in a boundary (302) between broadcast regions can select (704) the best frequency to tune to in order to present the service, without having to access a database to correlate service IDs to frequencies.
