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 have the Arcam 27 as a dvd player and you bet; some HBO /SHO movies have less pq. This applies to much of the local ota content as well.(i.e. the Rose Bowl game). Still much "hd" content is shown in 4.3. However "good-hd" content is no match for the best dvd. AND, the reverse is true for the audio.
