Abstract

A technique for performing channel detection in a device such as a television signal receiver is capable of quickly determining the analog and/or digital broadcast channels available in a given area. According to an exemplary embodiment, a method for performing channel detection includes tuning a first frequency channel, determining whether a signal parameter associated with the first frequency channel exceeds a predetermined threshold, and enabling a first channel acquisition operation responsive to determining that the signal parameter exceeds the predetermined threshold.
