Abstract
A primary broadcast receiver is automatically tuned by a secondary broadcast receiver receiving a first broadcast signal corresponding to a source of an origin program by program transition detectors detecting monochrome interprogram dead frame or closed captioning for the hearing impaired text words according to user-specified tune conditions; by a tuner controller enabling the secondary broadcast receiver and a program transition detector to begin monitoring a first broadcast signal currently tuned by the primary broadcast receiver, while allowing tuning of the primary broadcast receiver by a user, and by automatically tuning the primary broadcast receiver to the first broadcast signal upon signal by the program transition detector that one or more of the user-specific tune conditions have been met.
