Before signing up, many consumers want to know how Direct Satellite TV like Dish TV and Direct TV work, in terms of the satellite dish and its reception of signals. The signals broadcast by a satellite in space bounce off the curvature of the dish and onto the LNB, which filters out everything but the desired programming information. Then, the signals are sent down into your home to your Direct TV receiver, which turns the scrambled information into crystal-clear programming.

Features of Your Direct TV Receiver

This little box is far more advanced than the cable TV box you might be used to. Like a cable box, it will transfer scrambled information to your television screen, but it does it in different ways. It takes, from the satellite signal, just the signal for the channel you have selected - this is why two TVs on one receiver must watch the same program. If you want to watch different channels, you'll need a receiver on each set.

The reason why you can't get free Direct TV through piracy is that your receiver must have the right decoder chip for the programming package you've signed up for. If you don't have this chip, you'll only receive a scrambled signal, and gibberish on your screen. These receivers are smarter than cable boxes - they keep track of what you've watched, like pay-per-view movies, and signal to the satellite this information for billing purposes, automatically.

You'll enjoy the benefits of these 'smarter' boxes. They constantly update programming information, so they can provide detailed information on every piece of programming you watch, via the on-screen programming guide. It's like having a fully interactive television program guide right on your screen, through which you can 'flip' and 'highlight' your choices. Some of these can even give you options like TiVO functions and HDTV accessibility.
