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. A receiver, to automatically switch from presenting a service on a first frequency to a second frequency such as when a mobile receiver is moving through a boundary region between two broadcasters, can consider not just signal strength and error rates of two frequencies carrying the same service to select which frequency to tune to, but also relative location and direction of motion of the receiver with respect to each broadcaster along with parameters of the RF environment as previously measured by an autonomous vehicle such as a drone.
