Explained: What is D2M technology, and how could it change your mobile behaviour?

The Department of Telecommunications (DoT) and India’s community provider broadcaster Prasar Bharati are discovering the feasibility of a technological know-how that will allow to broadcast video and other forms of multimedia information instantly to mobile telephones, without the need of needing an active online link.

The technological know-how, known as ‘direct-to-mobile’ (D2M) broadcasting, claims to increase usage of broadband and utilisation of spectrum.

What is direct-to-cellular broadcasting?

The know-how is based mostly on the convergence of broadband and broadcast, employing which cell phones can get terrestrial digital Tv. It would be comparable to how persons listen to FM radio on their telephones, in which a receiver within just the cellphone can faucet into radio frequencies. Making use of D2M, multimedia content material can also be beamed to phones directly.

The notion driving the know-how is that it can perhaps be employed to specifically broadcast written content linked to citizen-centric info and can be further more used to counter bogus news, problem unexpected emergency alerts and offer guidance in catastrophe management, amongst other items. Apart from that, it can be utilised to broadcast reside news, athletics and so on. on mobile telephones. Extra so, the written content should really stream without having any buffering in any way whilst not consuming any world wide web data.

What could be the consumer and business impact of this?

For customers, a technological innovation like this would signify that they would be equipped to accessibility multimedia content from Video on Demand from customers (VoD) or Above The Major (OTT) content material platforms devoid of owning to exhaust their mobile info, and far more importantly, at a nominal price. The technology will also make it possible for persons from rural regions, with confined or no online access, to enjoy video clip material.

For organizations, one particular of the crucial positive aspects of the technology is that it can allow telecom services suppliers to offload online video targeted traffic from their cell community on to the broadcast network, hence encouraging them to decongest useful mobile spectrum. This will also boost use of cellular spectrum and free of charge up bandwidth which will assist lessen connect with drops, improve facts speeds and so on.

What is the government carrying out to aid D2M technology?

The Office of Telecommunications (DoT) has established up a committee to analyze the feasibility of a spectrum band for giving broadcast services immediately to users’ smartphones, DoT Secretary K Rajaraman stated on Wednesday. “Band 526-582 MHz is envisaged to do the job in coordination with equally mobile and broadcast solutions.

At the moment, this band is applied by the Ministry of Information and facts & Broadcasting throughout the region for Tv set transmitters.

General public provider broadcaster Prasar Bharati experienced past 12 months introduced a collaboration with IIT Kanpur to exam the feasibility of the technological innovation.

What are the attainable challenges to the technology’s rollout?

Though nonetheless at a nascent phase, Prasar Bharati’s CEO has said bringing crucial stakeholders like cellular operators onboard will be the “biggest challenge” in launching D2M know-how on a huge scale. Facts and Broadcasting Ministry Secretary Apurva Chandra explained a mass roll out of the engineering will entail variations in infrastructure and some regulatory adjustments.
