The Main Components Of Satellite TV Systems

Satellite television as we know it has come a long way from the 1990s when it was a relatively foreign concept and very expensive. Scientists, a few learning institutions and the wealthy were the only people who could afford the service at that time. The equipment required to access satellite transmission at that time was bulky and would take up huge amounts of space. This further distanced the service from regular television viewers. Today satellite dishes are owned by millions of television viewers due to the improvements the technology has gone through over the years.

The satellite services in the 1990s transmitted syndicate programs via C-Band. Regular free access programs were however not accessible via the service at that time. If they were accessible; viewers had to search endlessly to locate local channels via the satellite service. Today the satellite service is relayed to viewers through DBS providers. The providers transmit the satellite signal via Direct TV as well as Dish networks. The providers relay select sets of programs to subscribers who access the service through them. Satellite television is bundled up with hundreds of channels and can go up to 3000+ channels availed to subscribers.

Satellite television is transmitted through digital signals which results in high picture clarity when it reaches viewers. The sound quality is the best available and surpasses that of terrestrial based signals by far. Radio transmissions are relayed through 11.7 – 14.5 GHz DBS frequencies as opposed to early transmissions which were relayed via – 3.7 – 6.4 GHz C-Band frequencies.

The satellite signals through the direct to home transmission method reaches televisions through a series of steps. The signal originates from a broadcast center which bounces to the satellite on to the programming source from where it is sent on to satellite dishes and finally to the television receivers.
