Abstract
Systems for switching a displayed signal for a display between a plurality of signals are disclosed. In one embodiment, the system includes a microcontroller; a chooser for choosing a primary signal from a plurality of program-variable signals at the microcontroller; a monitor tuner coupled to the microcontroller for tuning the primary signal during switching of the displayed signal from the primary signal to a secondary signal; a detector coupled to the monitor tuner and the microcontroller for detecting a predetermined condition in the primary signal; and a selector coupled to the microcontroller for switching the displayed signal from the secondary signal to the primary signal upon occurrence of the predetermined condition. A user can switch between signals such as television channels or other dedicated functions without the risk of missing a portion of the program material.
