Cable free,Internet free & Set top box free TV through Digital Terrestrial Television(DTT)- DVB T2 broadcasting





In analogue terrestrial television broadcasting only one signal is transmitted on a given frequency channel. Digital Terrestrial Television (DTT) broadcasting allows the transmission of about 10 or more digital services in a single transmitter. In the DTT broadcasting process everybody watches the same content at the same time and it guarantees everybody the same high level of service. DD has adopted DVB-T2 standard for DTT services which are free-to-air.




Why is Doordarshan going into digital terrestrial broadcasting?





Doordarshan is giving terrestrial transmission of Analog Channels since 15th September 1959. DD is migrating to digital terrestrial broadcasting as going digital will provide multiple programme channels, better video and audio quality, availability of signals on mobile and portable devices like handsets/tablets/PCs etc.




How to receive DVB –T2 Signals? Do I need to change my TV set now to receive the DVB -T2 Signal?




It requires ordinary antenna (indoor or outdoor depending upon your location) as used in analogue terrestrial TV. With the existing TV set, a DVB - T2 Set Top Box is required. Some integrated Digital TV sets (iDTV) are available in market having in-built set top box or DVB-T2 tuner. With these TV sets one needs only an antenna to be connected to TV set for watching DTT channels.

How do I tune my STB/TV?





Make sure your digital TV or set-top-box is connected to an antenna. Tuning may take a few minutes. Every model of digital TV or set-top-box box will be a little bit different. Please refer to the user manual if required. Here are some general guidelines. Select the 'set up' or 'installation' option. Select digital tuning / Digital TV option. For full tuning, select the auto tuning option. This in some cases called ‘auto set-up’ or ‘first time installation’. Press ‘OK’ if the digital TV or set-top- box asks if you want to delete all your previous channels. Newly scanned Channels will automatically be stored and you should receive all the free-to-air channels. Unless there is any change from Transmitter end, rescanning may not be required.
