FACTS ABOUT THE RECEIVER
The end component in the entire satellite TV system is the receiver or the set-top box. It takes the digital signal and converts it into an analog format that a standard television can recognise. Since the receiver spits out only one channel at a time, you can’t tape one programme and watch another or watch two different programmes on two TVs hooked up to the same receiver. In order to do these things, which are standard on conventional cable, you need to buy an additional receiver.
Some receivers have a number of other features. They pick up a programming schedule signal from the provider and present this information as an onscreen programming guide. Many receivers have parental lock-out options, and some have built-in Digital Video Recorders(DVRs), which let you pause live television or record it on a hard drive.
