<p>Contemplated devices and methods employ a system in which at least two receivers are configured to receive at the same time a first and a second emergency signal via a first and a second communication pathway, respectively. The device further has a control unit that is programmed to assign priority to one channel of one communication pathway over at least one channel of the other communication pathway, wherein priority assignment is performed on the basis of geographic location and a set of predefined rules. Most preferably, the location of the device is automatically determined using global positioning signals and/or digital television signals.</p> |
