What is Dish Home DTH and How it works:
DTH stands for Direct-To-Home. Direct to home technology refers to the satellite television broadcasting process. It refers to a digital satellite service that provides television services direct to subscribers anywhere in the country. This technology is originally referred to as Direct Broadcast Satellite (DBS) Technology. Since this is a wireless technology, TV channels/programs are sent to the subscriber's television direct from the satellite, eliminating the need for cables and any cable infrastructure.
In order to receive DTH service, you need the following two basic components:
• Dish Antenna
• DTH Receiver /Set Top Box (STB)
It is a dish-shaped type of parabolic antenna (as small as 60 cm in diameter) designed to receive microwaves from communications satellites, which transmit data transmissions or broadcasts, such as satellite television. When the antenna is properly pointed, the dish "catches" the signal and reflects it to the Low-Noise Block (LNB) converter - included with the purchase of the antenna.
Set Top Box:
It is a digital integrated receiver/decoder (IRD) also called a receiver, which separates each channel and decompresses and translates the digital signal for viewing over a television; and a remote control.
