How to receive DTT Signals & How to Install DVBT2 System?

As you know Doordarshan stopped old analog traditional transmission in main cities. So from now if you want to watch the Doordarshan National channel or other Doordarshan channels like DD News, DD HD, and other TV channels then It requires an ordinary antenna (indoor or outdoor depending upon your location) as used in analog terrestrial TV. But now with the existing TV set, a DVB - T2 Set Top Box is required.

Some integrated Digital TV sets (iDTV) are available in the market having an in-built set-top box or DVB-T2 tuner. Only an antenna to be connected to the TV set for watching DTT (DVB-T2) channels.

DVB-T2 (DTT) signals are typically broadcasted by big TV towers (like TV towers for analog reception) on VHF or UHF frequencies over the air. DVB-T2 signals can be part of the VHF or UHF spectrum. So many countries are moving to this new technology due to its high-quality digital picture quality and digital sound.

DTT Chennai Doordarshan Kendra Frequencies:
  • Ch#26 ( Centre Freq 514) 8Mhz Bandwidth with the following channels in the bouquet.
  • DD National HD, DD Urdu, DD India  
  • Ch# 29 ( Centre Freq 538) 8Mhz Bandwidth with the following channels in the bouquet.
  • DD Podhigai, DD News, DD Sports, DD Bharati, and 3 radio channels

Do you know the main feature of this technology is that the DVB-T2 transmitter broadcasts signals through the air which can be received by a simple antenna or aerial, with multi TV channels? So, if you tuned to a single DTT frequency then it is possible to receive more than 1 channel on the same frequency.

    DTT seems to be eratic in North Delhi, i was able to get 12 DD plus 8 AIR channels all of a sudden once on 2 Dec 2022. Then later on 8 Dec got only two DD channels. But they all worked only once and since then i have tried various antenna locations but no signal is being received. Even during Common Wealth Games 2022 in Aug the signal stopped working after midnight. For many days i thought my iDTV has problem. Bad news if they have actually stopped.
