Satellite Television
Satellite television is television delivered by way of orbiting communications satellites located 37,000 km above the earth’s surface. It is television delivered by way of communications satellites, as compared to conventional terrestrial television and cable television.
In many areas of the world, satellite television services supplement older terrestrial signals, providing a wider range of channels and services, including subscription-only services. Satellite TV was a lot more difficult than broadcast and cable TV.
There are two primary types of satellite television distribution: Direct Broadcast Satellite (DBS) and Television Receive-Only (TVRO).
Direct Broadcast Satellite, either refer to the communications satellites themselves that deliver DBS service or the actual television service. DBS uses the upper portion of Ku-Band.
Television Receive-Only, refers to satellite television reception equipment that is based primarily on open standards equipment. TVRO systems are designed to receive analog satellite signals from both C-Band and Ku-Band satellite television or audio signals.
