Video A/B Timer

[GeorgeLawshe]

I have two composite video inputs and I want a switch that will play input A for 5 minutes, then input B for 3 minutes, then repeat on a 24/7 basis. I would like for the play time to be selectable from 2 to 10 minute.

Any suggestions?

hi,
You can buy 'scanners' for up to 4 AVI inputs, with 1 AVI output , the 'dwell' time for each channel can be selected, also it can be set to scan 2, 3 or 4 inputs.

If would prefer to build your own let us know.

A/B Video timer

Sorry, I could not find a timer for Input A and Input B with repeating dwell times.

I would like to build one if I had a good schematic. Thge building I can handle, it is the design I have problems with.

Thanks for your help
