Patent ID: 7872692

Claim:
A design structure embodied in a non-transitory machine readable medium for designing, manufacturing, or testing an integrated circuit, the design structure comprising: a system for switching a displayed signal for a display between a plurality of signals, the system including: a microcontroller; a chooser for setting a primary signal from a plurality of program-variable signals; 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; wherein the microcontroller is configured to: transmit a signal initiating a visible notification on either a remote control or a display coupled to the monitor tuner, and transmit a signal initiating a visible approval query on the display, the visible approval query allowing a user to choose whether to switch the displayed signal from the secondary signal to the primary signal.
