When we first got to know cable TV channels, we were blown away by the pretty clean picture and the huge selection of channels. Not long ago, we just discovered that there is also such a thing as satellite programming, which is said to have a clearer picture and a much wider selection of channels.
Most people became curious about what satellite TV is. So, what is satellite programming definition?

Satellite Programming Definition
Based on the concept, satellite programming is a wireless system to deliver television programs directly to viewers’ homes. At the same time, broadcast TV and transmitter TV broadcast their programs via radio signals.
Before getting into the satellite TV system, let’s first look at the beginning, namely broadcasting stations that use antennas to transmit radio waves to the surrounding area. Users will be able to pick up the signal with a smaller antenna – like the antennas, we still see a lot of over houses.
The main limitation of transmitter TV is the range. Radio signals are used to broadcast television broadcasts through the transmitting antenna in a straight line.
You must be in a straight line with the antenna to catch this signal. Small obstacles like trees or buildings are not a problem; a large obstacle, such as the planet itself, will bounce back the radio waves.
If the earth were very flat, you would be able to catch the radiation even if you were thousands of kilometers from the source. But because planet Earth is naturally curved, the range of signal lines can be cut off. The TV broadcast signal is also often disturbed, even in close areas.
To get a clear signal like a cable TV, you need to be close enough to the transmitting antenna without too many things getting in the way.
Well, satellite TV solves the problem of distance and interference by emitting beam signals from satellites around the earth’s orbit. Because the satellite is high above the sky, more subscribers can be reached. Satellite TV systems transmit and receive radio signals using a special satellite dish antenna.
At the beginning of their appearance, Satellite TV connoisseurs used to be adventurous. They can use a satellite dish to find special broadcasts that are not really for the general public, using satellite dishes and receivers.
They can even catch broadcasts of foreign stations, NASA activities, and other things transmitted through satellites.
Some satellite owners are still looking for such broadcasts. Still, most satellite TV subscribers now get their broadcasts from the providers who’ll provide them with DBS, an abbreviated version of Direct Broadcast Satellite (DBS).
The provider selects the program and broadcasts it to the customer as part of the package. The service provider’s goal is to give your TV dozens, if not hundreds of channels in a form similar to its rival, cable TV.
Unlike previous broadcasts, broadcasts by providers are completely digital, which means better picture and sound quality. The early broadcast was on C-Band radios in the 3.7 GHz to 6.4 GHz frequency range. However, the digital broadcasting satellites transmit broadcasts in the Ku (11.7 GHz to 14.5 GHz) frequency range.
