Some HDTV's come with one, some are HDTV-ready, meaning they lack the HD tuner.
Depending on what type of service you have, such as cable, the cable company provides a HD-cable tuner, and even one with a DVR in it. If you have satellite, you need the HD satellite tuner, plus the HD-dish antenna.
If you receive neither, and go with the off-air HD programming, you will need a tv antenna plus an outboard HD-tuner.
Since most of the HD programming is on cable or satellite, get one or the other.
HD tuners, HD cable boxes, and HD satellite tuners all need to be connected by either a component video cable (Red, Green, Blue) or through an HDMI cable or a DVI cable.
The HDMI cable is best, and transmits both audio and video. DVI is a video-only, and so is component video. If you are using a cable or satellite tuner, HD programming comes in Dolby digital surround sound (5.1channel) so you should connect the tuner to your audio/video receiver with a digital coax cable or a fiber optic cable.
Since these cables are all pretty expensive, you should check the connections on your tv, a/v receiver, and HD tuner or cable box or satellite receiver before shopping for any cables. Bring your a/v receiver model number, too. You can find a qualified a/v salesperson who can show you how to do a "video pass-through" hookup that uses your a/v receiver as the "hub". But some models will not pass the whole HD signal, if they're more than a few years old, so make sure to have your model #.
