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.
