This is where the DRM standard jumps in.
For radio the DRM standard that digitalize all radio broadcasting bands from 150 kHz to 174 MHz.
All existing broadcasts in those bands can benefit from their digitalization with DRM.

New services
In the digital era, the radio receiver has become a modem, an interface with the digital world.
Let’s see some examples…
Up to 4 Serviceson 1 Frequency
• With worldwide unique Service ID scanning, bookmarking, AFS
• Flexible Service layout:
• Audio-only Services
• Audio + PAD(Programme Associated Data)
• Multimedia/Data Services
Services & Structure
New services
Convenient Service Information,incl.
• Station Label(Unicode support, all scripts)
• Programme Type andLanguage
• Country of Origin• Announcements
(Traffic, Weather, News, …)• Current date / time / local time
offset
Search and select a Serviceby name, not by frequency
Services & Structure
New services
AFS per DRM Multiplex and per Service
• Multiplex-AFS:synchronous/non-synchronous
• Service-AFS:links to DRM/DRM+, AM, AM/AMSS,FM, FM-RDS, DAB/DAB+/DMB, etc.by Service-ID
• Clear definition of schedules and regions
• Automatic frequency switchingwhen leaving coverage area
• Seamless Switchingthroughout broadcast networks possible
• Single tuner background AFS scanning
AFS – Alternative Frequency Signalling
New services
Immediately alerts the populatione.g. in case of environmental disasters(tsunami / tornado warnings, etc.)
• Automatically re-tunes DRM receiversto a specified radio program / frequency
• Tunes to a DRM Servicesor any alternative broadcast system (e.g. AM)
• Textual information services providebackground information and instructionsfor listeners
Warning / Alert Feature
!!
New services
• Switch of DRM Multiplex configuration
• Pre-announced to receivers
• Often without audio interruption
• Two versions:
• Service Reconfigurationnew/changed DRM Services,signalling parameters
• Multiplex Reconfigurationchange in DRM Multiplex parameters(affecting overall bitrate)

• 5.1 Surround Sound for Digital Radio
• Revolutionary Radio Listening Experiencee.g. radio play, classical music, rock concert,broadcaster jingles, advertisement, sports!
• Listeners knows benefits from cinema/DVD:Radio EvolutionMono Stereo 5.1 Surround
• based on MPEG Surround: fully mono-/stereo receiver compliant very small bitrate for surround signal (e.g. 3-10 kbps) – no simulcast required Artistic Downmix for optimized stereo signal

SFN - MFN
• One of the key features of DRM:
– Networks of low power stations– Coverage of shadow areas (IP linked)– Any frequency bands– Made for mountainous countries and heavy urban
densities
• Makes digital radio for all possible
Savings
• Memory of sounds• Less energy consumption for network operators• Coverage of dark or far remote areas at low cost• Listeners can save money with their receivers• The more listeners the less expensive by
listener
Non proprietary standard
• All necessary details are available on – the ETSI and ITU (IEC) websites– The DRM consortium website www.drm.org

How much is the fee? • Covers all patents that are essential to build a DRM
radio (stereo) – a system license – No charge per unit for first 1,000 units
– $ 1.70 per units 1,001 to 500,000
– $ 1.50for units 500,001 to 1,000,000
– $ 1.38 for units 1,000,001 to 5,000,000
– $ 1.13 for units 5,000,001 to 10,000,000
– $ 0.88 for units 10,000,001 to 15,000,000
– $ 0.50 for units 15,000,001 or more
– Consumer Products with more than two Channels count as 1.5 units
– An initial fee of $ 1,000 is charged for taking out a licence agreement
• Professional equipment: 2% percent of end-user product price with a minimum of $ 100 and a maximum $ 2,000 per product
To whom the fee has to be paid?
• It is NOT the DRM Consortium!– The DRM consortium is a non-profit organisation
financed by the members– Committed to facilitate the deployment of DRM

Advantages of Open Standard Systems
• Multi-standard devices– Digital TV: ISDB-T in Brazil uses HE AAC by Dolby
– 1-seg mobile TV
– DRM / DAB+
• The portion of technology used in multiple applications (eg., audio compression) is covered by one license for this portion
1 x = 1 x $$
It is up to the manufacturer and his sense of market feasibility How complex, i. e. expensive a radio may be
Transparency
• DRM is the easiest and cheapest licensing program
• License fees are– Transparent and public– To be paid by the end user device
manufacturer– In a range of $ 1.3 for the entire system in
Brazil
The DRM reality 1/3
• Open standard• Transparent IPR process• Cost effective to operate• Respectful of environment• Within the frame of existing regulations• Enhance the commercial radio business• Increase the impact of public contents• Create the conditions for new contents
The DRM reality 2/3
• Revitalize frequency bands threatened by cellular phone companies appetite
• Complement broadband implementation at competitive cost
• Listening at no cost for the listeners is re-enforced
• Contents diversity is preserved by the number of content providers
The DRM reality 3/3
• FM like audio quality up to 30 MHz• Guarantee larger and quality coverages
thanks to SFN and MFN• Set the base of a new business model for
the radio broadcasting industry
• All those advantages are available for you.
So what about Digital Radio in Colombia ?
• A large country• Difficult environment• Sharp management of public money• Active and prosperous commercial
broadcasters• A necessity to revamp radio• Use the existing parameters (frequencies,
sites)
Coverage from French Guiana
Colombia is a DRM country
The community of the DRM members is ready to contribute to your decision process (TDF, BBC, DW, VoR, Ree, Thomson, Digidia, FhG, etc)
DRM contribution
• To your decision making process
– Seminars• Regulatory bodies• Broadcasters
– Trials• AM (MW)• SW (local and long range)• DRM+• Simulcast mode• SFN / MFN
Countries that have endorsed DRM
Countries where the DRM endorsement is under process / evaluation
