Cable TV High Definition converter


My brother in law told me today (I am a newbie to home theater) that if I have cable (Comcast) the HDTV signal being sent over the cable is being compressed and that there is a box I can buy that decompresses it so that I get true (or at least better) HDTV. Is this true? If so, what is this box called? What brands are there? Is any one of them better than another?

Thanks

I am a novice at HDTV, but I understand that the FCC has only recently set the final standards for cable and satelite transmission interfaces and the industry is only now starting to get their act together. I would be cautious until this fall.
