The end component in the entire satellite TV system is the receiver. The receiver has four essential jobs:
- It de-scrambles the encrypted signal. In order to unlock the signal, the receiver needs the proper decoder chip for that programming package. The provider can communicate with the chip, via the satellite signal, to make necessary adjustments to its decoding programs. The provider may occasionally send signals that disrupt illegal de-scramblers as an electronic counter measure (ECM) against illegal users.
- It takes the digital MPEG-2 or MPEG-4 signal and converts it into an analog format that a standard television can recognize. In the United States, receivers convert the digital signal to the analog National Television Systems Committee (NTSC) format. Some dish and receiver setups can also output an HDTV signal.
- It extracts the individual channels from the larger satellite signal. When you change the channel on the receiver, it sends just the signal for that channel to your TV. Since the receiver spits out only one channel at a time, you can't tape one program and watch another. You also can't watch two different programs 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.
- It keeps track of pay-per-view programs and periodically phones a computer at the provider's headquarters to communicate billing information.
Receivers have a number of other features as well. They pick up a programming schedule signal from the provider and present this information in 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.
These receiver features are just added bonuses to the technology of satellite TV. With its movie-quality picture and sound, satellite TV is becoming a popular investment for consumers. Digital cable, which also has improved picture quality and extended channel selection, has proven to be the fiercest competitor to satellite providers. The TV war is raging strong between satellite and digital cable technologies as well as between the providers who offer these services. Once considered luxuries in most households, satellite and digital cable are becoming quite common as providers bundle TV with Internet and phone services to offer competitive deals and win over customers.movies no good deeds the good deeds man has done before quote good deeds good deeds calendar thandie newton good deeds do your good deeds in secret another word for good deeds good deeds imdb good deeds clip art tyler perry good deeds watch online 10 good deeds hillary good deeds watch good deeds online free without downloading good deeds songs cast of tyler perry's good deeds necklace of good deeds bdo no good deeds movie 2014 cops doing good deeds good deeds nashua nh athletes doing good deeds good deeds as filthy rags good deeds to do every day watch good deeds online free destiny good deeds good deeds trailer addict what day did good deeds come out tyler perry good deeds soundtrack list 3 good deeds when will good deeds be on dvd dorcas good deeds what good deeds can i do all good deeds quote justin bieber good deeds good deeds day 2013 good deeds paragraph good deeds bible scriptures good deeds movies good deeds dvd release date good deeds jar good deeds scholarship 2015 good deeds islam list clifford the big red dog good deeds where is tyler perry movie good deeds playing when will good deeds be released on dvd tyler perry movies good deeds trailer good deeds trailer soundtrack police officer doing good deeds andrew jackson good deeds good deeds and tyler perry movie good deeds reviews watch tyler perry's good deeds full movie tyler perrys good deeds cast good deeds movie download articles of people doing good deeds good deeds meaning in english good deeds film mother teresa good deeds tyler perry car in good deeds good deeds day 2018 full movie no good deeds movie good deeds tyler perry don't brag about good deeds good deeds 2012 dvd cover good deeds lace up dress good deeds tyler perry torrent essay good deeds for life
