GS Paper - 3 (ICT)

The Department of Telecommunications (DoT) and India’s public service broadcaster Prasar Bharati are exploring the feasibility of a technology that allows broadcasting video and other forms of multimedia content directly to mobile phones, without needing an active internet connection. The technology, called ‘direct-to-mobile’ (D2M) broadcasting, promises to improve consumption of broadband and utilisation of spectrum.

What is direct-to-mobile broadcasting?

  1. The technology is based on the convergence of broadband and broadcast, using which mobile phones can receive terrestrial digital TV.
  2. It would be similar to how people listen to FM radio on their phones, where a receiver within the phone can tap into radio frequencies. Using D2M, multimedia content can also be beamed to phones directly.
  3. The idea behind the technology is that it can possibly be used to directly broadcast content related to citizen-centric information and can be further used to counter fake news, issue emergency alerts and offer assistance in disaster management, among other things.
  4. Apart from that, it can be used to broadcast live news, sports etc. on mobile phones.
  5. More so, the content should stream without any buffering whatsoever while not consuming any internet data.
