What are Standby and Alert switchers?
Standby or Alert switchers have one or more inputs connected to the “Alert” or “Standby” source. When the main video signal is interrupted for some reason, or in an emergency, the switcher switches automatically to the “Alert” or “Standby” source, which is either a “filler” or an emergency message. The switcher can be forced into the “Alert” condition manually or via a remote control.
