I am looking to delay the signal from a attic digital TV antenna in order to Sync with another TV that has a Cable HDMI input. The TVs are in different rooms , but the sound delay of the cable TV is extremely irritating. I need to delay The Antenna TV 2+ seconds and then I can sync using the Cable TV DVR. I have yet to become a true cord cutter as I'm addicted to the DVR, but avoiding paying for high definition on a second TV. Superbowl is coming and so both TVs need to be in Sync. Thanks
