Meaning of DTH service
The DTH (Direct To Home) service is basically a digital satellite service that provides satellite television programming directly to subscribers home anywhere in the country. Since it employs wireless technology, the television programs are transmitted to the subscriber’s television directly from the satellite. This service does not involve the usage of cables and any other wiring infrastructure.
A DTH network comprises of a broadcasting centre, satellites, encoders, multiplexers, DTH receivers and others.A DTH service provider is required to lease Ku-band transponders from the satellite. The function of encoder is to convert the audio, video and data signals into the digital signals. These digital signals are then mixed by multiplexer. On the receiving end at user home, the set up includes a small Dish Antenna and Set-Top Boxes which decode these signals and convert them back to audio, video and data signals.
Some of the popular DTH providers in India includeTataSky, Airtel Digital, Videocon D2H, Sun Direct, Dish TV, Big TV and others.
