How does satellite receiver work




















In addition, some spot beam services only serve specific large cities. Some free-to-air satellite TV channels are even available at no cost if you have a Free-to-Air receiver. Dish Network is a leading U. DigiCipher II provides compression, Your email address will not be published.

Let us know what you have to say:. Save my name, email, and website in this browser for the next time I comment. I want to install a Satelite TV at home. The end component in the entire satellite TV system is the receiver. The receiver has four essential jobs:. 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.

Some channels on satellites sell their channels frequency. This means, to decrypt their signals, users would purchase some specially designed receivers, not your normal receiver. Hence, it requires that users subscribe to get an LNB Low-Noise block , satellite dish, and receiver to decrypt and project signals on your TV screen s. The device draws signals from the LNB — typically installed outside — which receives signals from the satellites.

It then transmits the signals to your audio and video devices. These receivers usually work with scrambled channel networks. The receiver is widely thought the best entertainment device, globally. Besides receiving, decrypting, and projecting signals, this receiver allows users to rewind, pause ongoing programs, and even record future programs on the channels.

Satellite receivers come in different designs, models, and brands. So, here are some features and specifications to check out before you invest in any receiver. Many users wish they could get radio signals from their receivers. If that sounds like you, then opt for a receiver with radio signals.

Simply ask your vendor for a receiver with this function or check the product specification on the package. Thankfully, this feature is common in most receivers. Would you want to watch your satellite programs on more than one screen? Perhaps, to enable viewing in your bedroom and living room, simultaneously? Then, prefer a receiver with a multi-TV screen feature.

These specs are tailored to get signals and transmit audio and images, through multiple outputs, to more than one TV screen per time. Most receivers come with USB port s. This allows you to play music or work on applications and programs on your TV screen — via your gadget. This feature is a favorite for those who wish to stream music live or view shows on websites. Lost your satellite receiver manual? Read on. The orbiting satellite acts as both a receiver and a transmitter.

It receives the feed of channels from the service provider, then transmits that information back in a beam toward the Earth. The customer dish acts as an antenna. The dish picks up the signals and sends them to a receiver set-top box STB. For a more detailed analysis on how satellite television works, read our article on " How Satellite TV Works.

Older satellite system receivers convert the signal from a digitally compressed format like MPEG-2 into an analog signal. Satellite HD service uses the same principles as regular satellite television, but with different encoding methods.

With the right STB, you can decode and view this high-definition signal. In the next section, we'll learn how satellite service providers encode signals. We'll also discuss the equipment you'll need to receive those signals and decode them so that you can watch HDTV. High-definition television can display images that are much clearer and more colorful than standard television.

Before digital video, the standard signal format was analog, which had a resolution of about x pixels. When digital video technology entered the market, consumers suddenly had access to televisions that could display many more pixels, as many as x for some sets. Uncompressed video signals require a lot of bandwidth -- so much, in fact, that satellites can't handle receiving and transmitting that much information at the same time. That's why satellite service providers compress video signals, especially when they're high-definition video.

There are a few different MPEG encoding standards. Until recently, satellite systems compressed video using the MPEG-2 standard, which reduces video size by a factor of about This format is more efficient than MPEG-2 and is better suited for complex, fast-moving images like those in sporting events and action movies.

Before the switch to MPEG-4 compression, satellite service providers could only offer a few HD channels due to the demand on system bandwidth. As cable companies began to develop HD packages, satellite systems had to look for new ways to deliver HD signals to customers in order to stay ahead of the competition.

Unfortunately, this upgrade also means that customers have to upgrade their equipment in order to view that programming.
