DRM
smart radio for all digital radio Mondial is radio reimagined for all digital
radio Mondial or DRM is part of digital communications worldwide. DRM is
designed as a high quality digital
replacement for analog radio broadcasting with the DRM digital radio
standard the existing radio infrastructure can be modernized to offer listeners
so much more with some investment DRM offers vast benefits for example much
richer and better content for everybody using less energy digital radio Mondial
offers digital radio for all so how can we digitize a whole country with DRM
let’s imagine a country called integria with cities and villages mountains and
deserts this imaginary country may be a bit like yours has 25 million inhabitants
digitalia its capital of 6 million people is a trading and banking center there
are also two other medium-sized cities in the west some semi-autonomous townships in the south
and a great forest region dividing the country in two agriculture is important
and the rural population is spread over large areas integria this medium-sized
country with a limited GDP has many communication challenges how to provide new
information entertainment and education to the whole of the population how to
warn people of dangers an disaster be they man-made or natural currently
integria has an integrated radio broadcasting network using shortwave
mediumwave and FM transmissions which can be received by most people in many
but not all areas of the country the public service broadcaster called national
radio NR uses one old short wave transmitter and three medium wave transmitters
that cover mainly rural areas in the cities low power but expensive FM stations
deliver a mixture of news and travel content in several languages and dialects
but their signal does not travel far beyond the city limits so FM covers about 15 percent of the
population and medium wave 80 while village in the great forest region do not
get any coverage however people in rural areas would like more radio in local
languages for more hours in the day DRM is the only digital radio system that embraces
all the currently used radio frequency bands can help improve the radio service
for integria DRM can offer full national and international coverage to
integria’s public broadcaster DRM cm offer services to smaller community
stations for the needs of local listeners in small cities and villages DRM
allows the broadcaster to transmit up to three different radio broadcasts from
one single transmitter so you could have a greater variety of radio content so
what’s the plan to migrate the current analog system to digital in integria one
option is to establish or upgrade DRM
the existing shortwave transmitter
covering the whole of integria to include the capital the cities the townships
the great forest each rural area from one secure location this mean national
radio programs and emergency notifications can now reach everyone a second
additional option is to establish or upgrade the existing medium wave
transmitters just for regional coverage each of these transmitters can carry up
to three radio broadcasts so the contents can be richer more varied and in the
regional languages or dialects a medium wave transmitter switched over to DRM
provides the provide the same coverage but using up to 50 percent less power
than analog that’s a lot of energy savings a further option is to digitize the
FM 
radio
stations in the capital and in other parts of the country the FM stations
commercial or state funded could also benefit from DRM more content in more
languages on flexible DRM for all.
All these three
digitization scenarios can be scheduled and combined in order to reach all of
the citizens of integria let’s look at the extra benefits of DRM well it’s not
just audio DRM radios also have a screen and DRM can provide data along with the
audio broadcasters data means text and pictures from maps to maths lessons live
sports results in different languages and emergency warning in case of
disasters DRM provides an opportunity with digital station managers to use this
data channel to create a new revenue stream In summary, Digital Radio Mondiale.
DRM is flexible, green and delivers universal access to information. So the whole country can be connected. And every pupil and
student of Integria can be provided with education even in the remote areas
with no internet access. With more radio broadcast, there are opportunities for
more jobs.
Emergency
broadcasts can also be regionalized and transmitted from safe areas only to be
affected zone or locality. The government are asking the residents of south
haven to stay indoors in a national emergency the DRM local regional and
national broadcasting network allows the government to alert and talk to all
the integrial citizens during any kind of disaster as they have an emergency
channel available at a moment’s notice integria can now benefit from the
reinvention of radio and enjoy excellent sound quality for small or large area
broadcasting with country-wide coverage up to three time as many broadcasts
using the same transmission infrastructure 50 to 90 percent transmitter energy
saving depending on the transmission infrastructure a text and picture service
by radio which helps with general information and education a national
emergency warning feature that can be used at the flick of a switch a new
receiver industry and extra jobs in broadcasting and manufacturing so what are
the key steps to successfully rolling out digital radio in integrial or your
own country to enjoy superior digital radio for all a regulatory framework is
required the government needs to promote digitization publicly and actively let
broadcasters know when digital frequency license will be available and when the
digital services will be launched regulators broadcaster receiver manufacturers
and retailer need to work together from the start of the digital radio project
remember digital broadcasts cannot be heard using analog receivers nearer to
the digital radio launch date there needs to be public awareness campaign
especially in remote areas the government could consider subsidizing new receivers so that their prices are as low
as possible the government could also request and receive grants and funding
from international organizations DRM encourages a home-grown radio
manufacturing industry there’s no reason why local manufacturers couldn’t
develop DRM digital radios for integria it doesn’t matter whether manufacturers
want to make standalone radios retrofit receivers in old cars or add them to
brand new vehicles DRM is an open standard available to anybody listeners are
the ultimate beneficiaries in a successful rollout of digital radio DRM
technology enable great and rich content and can safe lives DRM is radio
reimagined for the benefit of all
