SUBSCRIBE NOW ON SATELLITE TELEVISION BECAUSE BY 2020 YOUR TV WILL NO LONGER RECEIVE ANALOG SIGNAL YOU CAN'T WATCH TV ANYMORE. TV SIGNALS DIGITALLY BROADCAST ALREADY.
atellite television is a system of delivering television programming using signals relayed from communication satellites. The signals are received via an outdoor parabolic reflector antenna usually referred to as a satellite dish and a low-noise block downconverter (LNB). A satellite receiver then decodes the desired television programme for viewing on a television set. Receivers can be external set-top boxes, or a built-in television tuner. Satellite television provides a wide range of channels and services, especially to geographic areas without terrestrial television or cable television.
The most common method of reception is direct-broadcast satellite television (DBSTV), also known as "direct to home" (DTH).[1] In DBSTV systems, signals are relayed from a direct broadcast satellite on the Ku wavelength and are completely digital.[2] Satellite TV systems formerly used systems known as television receive-only. These systems received analog signals transmitted in the C-band spectrum from FSS type satellites, and required the use of large dishes. Consequently these systems were nicknamed "big dish" systems, and were more expensive and less popular.[3]
The direct-broadcast satellite television signals were earlier analog signals and later digital signals, both of which require a compatible receiver.Digital signals may include high-definition television (HDTV). Some transmissions and channels are unencrypted and therefore free-to-air or free-to-view, while many other channels are transmitted with encryption (pay television), requiring a subscription.- SOURCE WIKIPEDIA
