DIGITAL TERRESTRIAL TV (DTT)

The existing Analogue TV Transmitters in India serve about 88% of Indian population. Constrained by limited frequency capacity, the analogue terrestrial television platform needed a new & more efficient transmission system to meet the demands of the future and to allow for the launch of new services. India has adopted DVB Standard for its digitalization of terrestrial network. The 2nd generation DVB T2 Standard, launched in June 2008, has about 50% more capacity than its first generation DVB T. The DVB T2 Transmitter has high data capacity (upto 40 Mbps). Digitalization of Doordarshan’s Terrestrial TV Transmitters has been started in 63 cities under XI and XII Plan. DVB- T2 Transmitters are equipped for Fixed, Portable and Mobile equipments. Doordarshan plans to install DTT Transmitters at 630 locations all across the county in future.

These cities are: Delhi, Mumbai, Kolkata, Chennai, Guwahati, Patna, Ranchi, Cuttack, Lucknow, Jallandhar, Raipur, Indore, Aurangabad, Bhopal, Bengaluru and Ahmedabad.
