D2M Technology

Tags: Science and Technology

The Department of Telecommunications (DoT) and Prasar Bharati are exploring the feasibility of ‘direct-to-mobile’ (D2M) broadcasting.

• What is D2M Technology?

• This technology is based on the convergence of broadband and broadcast, using which mobile phones can receive terrestrial digital TV.

• This would be similar to how people listen to FM radio on their phones, where a receiver within the phone can tap into the radio frequency.

• Using D2M, multimedia content can also be beamed to phones directly.

• Benefit and need of D2M Technology

• It allows video and other forms of multimedia content to be transmitted directly to mobile phones without the need for an Internet connection.

• It improves consumption of broadband and utilisation of spectrum.

• This technology can be used to directly broadcast content related to citizen-centric information. 

• It can also be used to combat fake news, issue emergency alerts and provide assistance in disaster management.

• In addition, it can be used to broadcast live news, sports, etc. on mobile phones.

• Government's initiative to facilitate D2M technology

• The Department of Telecommunications (DoT) has constituted a committee to study the feasibility of a spectrum band to provide broadcast services live on users' smartphones.

• Band 526-582 MHz is envisaged to work in sync with both mobile and broadcast services.

• Currently, this band is used by the Ministry of Information and Broadcasting for TV transmitters across the country.
