Satellite TV System
The satellite was introduced long ago and the viewers can different programs and shows live from other countries. They used their costly dishes which help to discover the unique and wonderful programming, which was not intended for mass audiences. They used dish and receiving equipments to give the tools to the viewers to pick up the foreign stations and live feeds among various broadcasting stations and cover the NASA activities and it also provided various other stuff, which were transmitted through the use of satellites.
Now most of the satellite TV customers get their programs with the use of direct broadcast satellite provider like DISH network or DirecTV. They select the programs and also broadcast them to their subscribers and offer the package. It is goal of the provided to bring various or hundreds of channels to the TV and it can approximate the cable TV.
The broadcast of the provider is digital and it provides better picture and sound quality. The initial satellite television was broadcast in C-band radio and it radioed in 3.7 gigahertz to 6.4 gigahertz frequency range. The digital broadcast satellite is transmitting the program in Ku frequency range of 11.7 GHz to 14.5 GHz.
The users will find five big components, which are involved in Direct To Home (DTH) to Direct BroadCasting (DBS) satellite system, which is the programming source, the satellite, the broadcast center, the satellite dish and receiver.
- Programming sources are the channels, which are responsible to provide programming for broadcast. The provider does not create the original programming but it pays other companies (HBO, for example, or ESPN) to get the right for broadcasting of their contents through satellite. The provider is working as a broker between you and actual programming sources like Cable TV companies, which work on the same principle.
- The broadcast center is the center of the system and the broadcast center works as the TV provider to receive the signals from various programming sources and beams a broadcast signal to satellites in geosynchronous orbit.
- The satellites receive the signals from the broadcast station and it sends these signals to the Earth.
- The dish of viewer picks up signal from the satellite (or the multiple satellites works in the same part of the sky) and passes it on to the receiver in the viewer’s house.
- The receiver processes the signal and passes it on to a standard TV.
The Wild Side
The viewers of the early satellite TV used C-band radio for the broadcast and they were able to catch the wild feeds of syndicated programs, news and sporting events. The broadcast services were provided to them freely and the viewers had to find them but they did not get the preview or made it listed like the regular broadcast programming. The signals are there and the satellite orbit magazine published the list of the wild feeds of today.
