If you subscribe to Cable TV:
You will continue to receive your stations as you do today, whether you have a cable box or not. There is nothing you need to do. If your TV is connected to Cable ONE, your TV will continue to work after June 12th, 2009.
If you have TV’s connected to Antenna only:
You will need to either purchase a digital converter from a retailer (see Digital Converters section), buy a TV with a digital tuner, or get your additional TV’s connected to cable.
