Digital Terrestrial Television




The existing 1412 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. Therefore digitalization of Terrestrial TV Transmitters has been started by Doordarshan  at 40 cities and another 23 Transmitters have been approved in XII Plan.  India has adopted DVB Standard. 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). Further upgradation of DVB Standard ETSI EN 302 755 V1.3.1 (T2-Lite) in June 2011, it has provided more flexibility for Mobile TV and T2 Radio alongwith transmission of SDTV and HDTV programmes. . 

The T2-Lite profile is basically a subset of the DVB-T2 standard which is called now "DVB T2-base" profile and the Future Extension Frame (FEF) feature of the DVB-T2 standard enables transmitting services using both the DVB-T2 Lite and DVB-T2 Base profile within the same frequency channel. The DVB T2 Transmitters are thus equipped for Fixed, Portable and Mobile equipments. Accordingly to reap its benefits DD adopted DVB T2 standard. With Digital Terrestrial Transmitters it will be useful for Fixed, Portable and Mobile devices. 

DTT Update

Doordarshan started Mobile TV in India:

Digital Terrestrial  Television services to provide mobile TV  at 16 cities e.g Pitampura(Delhi), Mumbai, Kolkata, Chennai, Guwahati, Patna, Ranchi, Cuttack, Lucknow, Jallandhar, Raipur, Indore, Aurangabad, Bhopal, Bangalore and Ahmadabad, have been started from 25.02.2016. Mobile TV can be received using DVB-T2 Dongles in OTG enabled smart phones and tablets, Wi-Fi dongles, besides in integrated digital TV(iDTV). While iDTV are available in plenty like Sony, LG, Panasonic, Samsung etc., the dongles are also available in online Flip kart and eBay. Public and private transportation vehicles and public places are potential environments for Mobile Television. Currently DD National, DD News, DD Bharati, DD Sports, DD Regional/DD Kisan are being relayed. Only one time investment of Dongle will be required by viewers and no extra expenditure unlike streaming with internet.

Why Terrestrial TV?

Doordarshan is transmitting all free-to-air channels in analog format since 15th September 1959. It is necessary to migrate to digital terrestrial broadcasting as the world is moving away from analogue to digital broadcasting. Going digital will provide multiple programme channels , better video and audio quality, provide signals for  mobile and portable devices like mobiles/tablets/PC etc. and other value added services, besides it will allow   the government to free up frequency spectrum which can be used for new services like mobile, wireless broadband and potentially more TV services and channels. 

Some advantages of DTT Transmission are as below:

1. Analog TV (ATV) is subject to interference, such as ghosting and snow, depending on the distance and geographical location of the TV receiving the signal. 

2. SDTV pictures are free from "ghosting" and "snowing", which are commonly found in analogue TV pictures.

3. Digital digital TV supports Standard Digital TV (SDTV) High Definition TV (HDTV) and Ultra High Definition TV (UHDTV).

4. DTT secures greater plurality in Platform ownership, ensuring that no single platform owner is so powerful that they can exert undue influence on public opinion or political agendas.

5.  The DTT will provide signals for portable and mobile devices and also provide signals for Vehicles etc. 

6. The digital transition offers an opportunity to increase the production of local content. This in turn creates job opportunity and increase creativity and entrepreneurship. 

7. A strong DTT platform is critical to healthy competition in the TV market and to the realisation of a wide range of social benefits and most essentially an all weather reliable platform and unlike DTH there is no risk of catastrophic failure of total network. It provide alternative distribution platform. 

8. DTT creates the opportunity for convergence . Services like internet, LTE A+ overlay are feasible with DVB T2.

Broadcasting and telecommunications are in many countries treated as separate, vertical markets. But the digital technology creates the possibility of service convergence, infrastructure convergence, terminal and service provider convergence. The digital dividend at the UHF band has a potential to provide mobile internet broadband services to the rural and that will help greatly to fulfil one of the millennium development goals of bridging the digital divide. 

How to receive DTT?

It require ordinary antenna (Indoor or outdoor depending upon location of your site) as used in analogue TV. With the existing TV a Set Top Box compliant with DVB T2 Standard is required. But some integrated Digital TVs (iDTV) are available in market having in built set top box. Additional equipment required will be a 75-ohm coaxial cable and a HDMI cable if you are using the DVB T2  set-top box.  

The mobile should be  with USB host function or ‘On The Go’(OTG) enabled Android Phone. Any such mobile is capable to transfer data to devices like Pendrive etc. It is always described in mobile specifications. Some examples of such mobile includes:  Micromax Q380, Oppo Joy 3 A11W, Intex Power HD, Lava iris X8, Samsung DUOS etc. DVB-T2 Dongles will be required for attachment to such mobile. Some Wi-Fi Dongles with antenna are also available in market. If such wi-fi dongle  with  antenna is plugged on power and  placed near to window, the signal may be received in mobile/tablet  within 20 m from it.
