I need help with designing a circuit. I am a software and mechanical
engineer and I am hopeing someone out there can help. I need a circuit that
when it recieves power it overlays a timer on the screen of a tv and counts
down. Then when it hits 0 it turns off the video signal. I know the main
chip for the overlay that I want to use will be the STV5730 but I am not
sure if this will hold all the programming logic, or do I have to have a 555
chip do the coutdown and then tell the STV5730 to turn off the signal. It
needs to be a stand alone circuit and not hooked up to the computer. Can
someone please help I have been looking on the internet for information for
days. Thanks in Advance, Joey
