A DTV signal detector detects DTV signals received by a receiver on a selected DTV channel in a Digital Television System. The DTV detector includes a first DTV signal detector that detects a first characteristic of the received DTV signals, and a second DTV signal detector that detects at least a second characteristic of the received DTV signals. A controller responds to the first DTV signal detector and the second DTV signal detector to control a selection of the DTV channel being selected by the receiver. The receiver can be synthesized to select from more than one DTV channel.
