There was a article published in Today’s (25/09/2013) Hindustan Times (Delhi) – Hindi Edition about Doordarshan (DD) aiming to provide 600 channels by DVB-T2 transmission in India.
Here are few points translated to English from the article. Thanks to Mr.Vinay for the translation.
Doordarshan, the popular public service broadcaster with wide reach across India through various modes like Analog Terrestrial and Digital Satellite, will be using DVB-T2 (Digital Video Broadcast – Terrestrial 2) the newest transmission standard that fits in many digital channels in a single transponder (read VHF/UHF analog frequency). Both Free and Pay channels can be carried over DVB-T waves. Upto 600 channels are proposed to be beamed by DD using this DVB-T/T2 technology leveraging existing TV transmission towers commissioned across India for Analog Terrestrial channels.
Users who have DVB-T/T2 tuners built-in their TV will not need Set-top box, just Yagi antenna (fish bone type) connected to their TV Antenna In connector.
Those with old TVs not having DTV tuners have to buy DVB-T/T2 Set-top box or a DVB-T/T2 USB dongle for their Computers.
DD finds DVB-T transmission 25% cheaper compared to DVB-S transmission as no satellite is needed only use existing TV towers releasing QAM modulated waves with retrofitted DVB-T hardware, hence attempts are made to rollout this in metro cities followed gradually by other places too covering the entire nation.
