Using an HDTV Satellite
Other than your actual television of course, the HDTV satellite is going to be the single most important piece of equipment that you will purchase. It is this satellite which is going to be pulling in the HDTV signals and broadcasting it on your TV.
HDTV over HDTV satellite is actually one only one way to receive HDTV, as you can also get it through local cable companies and over the air. Basically what happens is that a satellite company such as DirecTV or Dish Network will allow you to get high definition programming from them. Keep in mind that if you decide to go this route, you will most likely end up having to pay a bit extra to receive local channels, say if you wanted to be able to watch local news.
So remember that if you decide to get HDTV programming from a satellite company you will have to get a subscription from the specific satellite company that includes HDTV programming, buy a HDTV satellite dish that is capable of receiving HDTV signals from the satellite company of your choice.
Then you need to buy a set-top-box that is capable of decoding high definition channels and which is compatible with the specific satellite provider that you chose, and then finally buy a high definition TV so you can actually view the signals.
Keep in mind that you do not have to buy an entirely new television if you don't want to, because you can use an HDTV converter to get HDTV on your regular analog television.
