A system and methods perform an automatic TV signal/tuner setup in a tuner device (e.g., a PC, a personal video recorder, a set-top bo x, etc.) that has one or more tuners. The setup identifies the number of tuners in th e device, whether the tuners are analog or digital, and what broadcast standar d each tuner supports. The geographic region in which the device will be receiving TV signals is ide...

Operating parameters as were previously learned by a first movable barri er operator (18) are transferred to a second movable barrier operator (10) such as, for example, to a replacement movable barrier operator. Pursuant to a preferred approach, such information transfer occurs via a receiver interface (13) that ordinarily serves to couple the movable barrier operator (10) to one or more remote u...
