The DTH technology involves individual dish placed outside the home that is able to receive signals from the service provider’s satellite and directs the signal onto the television inside the house. There are 5 major components that enable DTH technology to work.
- Broadcaster or the source of the TV programs. These are the channels that the service provider pays for obtaining the rights to broadcast them to its subscribers.
- Broadcast center that receives signals from different program sources or channels. The center then sends the broadcast signal to the satellite present in its geosynchronous orbit. This is the geostationary equatorial orbit of the satellite. The satellite completes one orbital round of the earth in one day.
- The satellite that receives the signal from the broadcast station. It then re-broadcasts or redirects the signal to the Earth.
- Individual dish attached to the outside of the subscribers house. This dish catches the signal from a single satellite or multiple satellites and passes it to the receiver that is present inside the viewer’s home.
- The receiver receives the signal from the dish and transmits to the television for viewing.
