What is DTH ?
DTH is Direct to Home service for receiving TV service directly through satellite with a personal small dish antenna. DTH service does not require a local cable operator for receiving TV service at home
What is DD Free Dish?
Doordarshan’s DTH service which known as DD Free Dish was launched in December 2004 with the modest capacity of 33 channels. This service was inaugurated by Hon’ble Prime Minister of India. DD Free Dish has been upgraded from time to time. At present its capacity is 104 SDTV channels along with 40 Radio channels. DD Free Dish is available in Ku-Band on GSAT-15 (at 93.5°E). This Ku-Band DTH service provides the TV coverage throughout the Indian territory (except Andaman & Nicobar Islands). DTH signals can be received through a small sized dish receive system ( i.e. Set Top Box and Dish of size of 60 to 90 cm in diameter) for which no monthly subscription fee is payable by the viewers.
Future of DD Free Dish?
Expansion of DD Free Dish has been carried out from time to time. With the introduction of new MPEG-4, DVB-S2 stream, the present capacity of 104 SDTV channels and 40 Radio channels is likely to be enhanced in near future. There is also plan to introduce HD channels in the bouquet of DD Free Dish. The 80 channels of MPEG-2 streams will also be expanded to MPEG-4 in phased manner.
How DD Free Dish is different from other DTH systems?
Most of the DTH operators, provide paid DTH Service. In the paid service, the DTH operators uplink the encrypted TV signals to the satellite and the signals are received by subscribers through a Dish receive system having a Dish Antenna and one Customized Set Top Box (DIGITAL DECODER). By choosing the bunch of various desired TV channels subscribers are charged by DTH operator for viewing these channels.
Whereas, viewing channels on DD Free Dish is absolutely free, as Doordarshan is not charging any monthly subscription fee from the viewers for complete bouquet of the DD Free Dish channels, making the system quite affordable. It requires only a small one time investment in purchasing a Dish Receive System containing Set-Top-Box and small sized Dish Antenna with LNB.
How to receive DD Free Dish?
Receive system of DD Free Dish contains three units: 1) One small sized Dish Antenna along with LNBF 2) Indoor Set-Top-Box (STB) also known as IRD (Integrated Receiver Decoder) and 3) Handy Remote control unit for STB. Dish Antenna installed at the roof top or on wall facing clear south receives the signal from satellite and transmits it to the indoor Set top box unit. The set top box further decodes the different TV channels from the DTH bouquet and feeds it to the TV set for viewing.
The complete DD Free Dish DTH system (Dish Antenna, Set Top Box and Remote control unit) is a one-time purchase from the open market with a nominal cost. There is absolutely no further recurring expenditure in terms of monthly subscription etc. for viewing DD Free Dish Channels.
Doordarshan has recently empanelled eleven Indian Set Top Box (STB) manufacturers who will manufacture, sell and install DD Free Dish STBs in India.
