Thread: How To Convert Standard Definition Cable Tv to High Definition?

I want to convert my standard definition cable tv signal to high definition. Is this possible using a tuner or set top box. I have a coaxil cable coming out of the wall. Thank you and if there is a set top box please give the company and model number.
And I own an hdtv.

you have to contact your cable company and have them give you a box that is hd compatible, otherwise you'll never be able to get the channels
