D2M technology

Context:

  • The Department of Telecommunications (DoT) and India’s public service broadcaster Prasar Bharati are exploring the feasibility of a technology that allows to broadcast video and other forms of multimedia content directly to mobile phones, without needing an active internet connection.

What is the D2M technology?

  • Mobile phones can receive terrestrial digital TV using this technology, which is based on the convergence of broadband and broadcast.
  • It would work in the same way that people listen to FM radio on their phones, with a receiver built into the phone that can tap into radio frequencies. Multimedia content can also be immediately broadcast to phones via D2M.
  • The technology’s concept is that it might be used to directly broadcast content relating to citizen-centric information, as well as to combat fake news, issue emergency alerts, and provide disaster management help, among other things.
  • It can also be used to broadcast live news, sports, and other content to mobile phones.

Impact:

  • Consumers would benefit from this technology because they would be able to access multimedia content via Video on Demand (VoD) or Over The Top (OTT) content providers without using up all of their mobile data, and at a low cost.
  • People in rural locations with limited or no internet access will be able to consume video material thanks to this technology.
  • One of the major advantages of the technology for businesses is that it allows telecom service providers to transfer video traffic from their mobile network to the broadcast network, allowing them to free up valuable mobile spectrum.
  • This will also optimise the use of mobile airwaves and free up bandwidth, reducing call dropouts and increasing data speeds, among other things.
