How Satellite Televisions Work

Satellite televisions have come a long way from the days of large-bulky backyard setups. In 2015, satellite technology has advanced to the point where equipment has sleek modern designs and requires minimal space with less invasive installations. At Cave Integration, we install a variety of satellite systems for both televisions and the oil and gas industry; continue reading this blog to find out how satellite televisions work.

Every neighbourhood in Calgary had at least one neighbour they were envious of, because they had a satellite dish in their backyard. Walking by their satellite dish, you’d often wonder, how many channels they received? What was considered a cool satellite dish back in the day would be considered an eye sore today. With modern satellite providers, the satellite dishes are smaller and have greater signal availability. There are five main components for a home satellite system:

  • Source
  • Broadcast center
  • Satellite
  • Satellite dish
  • Receiver

The programming source is channels that provide programming options and are made available to broadcast. They essentially pay television companies such as HBO and ESPN for the rights to provide their content for consumers.

The broadcast center is the main hub of the entire satellite system; receiving signals from programming sources and then transmitting that signal to satellites in space.

Satellites in orbit then relay signals received back to earth.

Satellite dishes receive the outgoing signal from orbiting satellites and pass the information on to a receiver located in a home.

Your home’s receiver will have the capability to process the signal so it can play on your television.

The signal your receiver picks up from the satellite dish contains a large amount of information and it needs to be compressed. Compressed signals simply mean that some of the unnecessary information is removed and then reconstructed after they are transmitted. Older satellites technology used C-band radio, which had a maximum frequency range of 6.4 GHz. Modern satellite services transmit programming at Ku Frequency range of 14.5 GHz. Ultimately, modern digital signals are stronger, enabling them to have greater image and sound quality.

Satellite systems are becoming a common feature in both offices and homes in Calgary. To find out how Cave Integration can install a satellite television system for your home or office, contact us in Calgary today at 403-978-2580.
