Get Broadcast Digital TV on old XP MCE 2004 ??

Yes, most likely I'll be updating to Win 7 & this is more of an unimportant "curiosity thing"- as I already, have a digital tv w/sat reception- & rarely, use the MCE for anything other than a desktop PC.

Sooo- is getting aerial broadcast digital reception via a XP MCE 2004 as simple as replacing the current "tv card" with a different one w/digital capability & adding some appropriate drivers ? And/or- is other software required? And if, it's a matter of simply another card/board- what model would be best?

Like I said- it's unimportant & I'll likely, not bother with it...but, out of curiosity-I've spent the last hour googling around w/little luck & thought I'd pose the question here.

Thanks, for any input!
