Satellite TV receiver

The role of the satellite TV receiver is to convert signal coming from the LNB unit (frequency down-converter/signal-amplifier part of the satellite dish) into electrical signal, so that it can be utilized by the TV set. Receiver component in charge of this conversion is the tuner. It also makes polarization switch - if utilized by the emitting satellite and the LNB - possible at the TV set level.

Entry level receivers come with a single tuner and single TV output. Each TV set requires separate receiver of this kind and, consequently, programming of each TV set is limited to that one satellite.

These receivers can't record programming - it takes connected separate VCR or DVD recorder. Other than that, they are perfectly capable of handling programming. Some of the usual features are customized program guide, tune-in timer, parental controls and on-screen caller ID support.

Capability of recording programming comes with DVR (digital video recording) receivers. They have a built-in hard drive, with up to 200 hours, or more of a standard digital recording capacity. Also, they usually come with a dual satellite tuner, allowing for the use of programming from two different TV satellites at the same time. Their recording ability broadens the list of available goodies with features like "pause" live TV, slow motion, or instant reply. The hard-drive presence allows for more of extra features, like "search programming", or filing and arranging of recorded contents.

The advance of high-definition (HD) programming brought about receivers capable of handling HD programming. Similarly to standard digital receivers, HD receivers also come with or without DVR capability. Today's top-of-the-line receivers are DVR/HD-capable, with up to two dual satellite tuners for the ultimate in programming volume and versatility.

There are several receiver models featured by either of the two satellite TV service providers, Dish Network and DirecTV. Also, a great variety of receiver models made by electronics companies specifically for one or the other system is available on the open market.
