Satellite Television Systems - How Live Broadcasts and Transmission is Sent and Received
Basically a satellite broadcast carries both picture and sound signals and they are broadcasted in C-band radio (3.4 Gigahertz [GHz] to 7 GHz). The Ku band frequency (12 GHz to 14 GHz) was introduced to provide superior video and audio to its subscribers. This actually led to the invention of the High-Definition Television (HDTV) with increasing optimal picture and sound quality as the one found in today's theater and cinemas.
The broadcasts from the satellite transmission are converted into a high-quality, uncompressed digital stream containing a lot of data, and sends it at a speed of 270 megabits per second (Mbps) for each channel. The broadcast data is compressed, so that the satellite would be able to receive it. The system of compression used in the U.S. is the MPEG-2 compressed video format.
The satellite service broadcaster also known as direct broadcast satellite (DBS) providers could now reduce the 270-Mbps stream to about 5 or 10 Mbps, enabling them to transmit about 200 channels, instead of the 30 they could transmit before compression. The signal was scrambled so only paid subscribers could receive it.
This was the turning point towards the huge success the DBS providers now experience. This technique of been able to compressed these channels and decode them on arrival put them ahead of the cable companies. The receiver device at the subscriber end accepts the transmission and converts it into a format that can be viewed on the TV.
The receiver does three basic things. It receives and de-scrambles the broadcasted signals with the help of the decoder. It separates the individual channels as requested by the subscriber by way of the channel selector button on the TV or remote control. It tracks the subscriber pay-per-view usage, the special programs being order, and sends your billing information for this programming to the provider.
