RDS2 A new challenge . And what it is all about
Extended data capacity for RDS will offer huge opportunities for new applications for both Broadcasters and Service providers
RDS2 Info Day 2016

RDS is a success story and Mature
The Car industry was the key driver In the development of RDS
Program features: PS, AF, PTY, EON, CT
A rich variety of features with only a few hundred bits/s available
Automotive features: TA/TP, AF, TMC
Growing need for added value features And new applications by ODA

• FM radio with RDS is mature, cheap and universally available
• Traffic services TA/TP and TMC are well established
• The perceived audio quality does not differ significantly from that heard via Digital Radio
• Because due to sophisticated technologies like Multiple tuners; Multiple antenna systems and RDS algorithms this system is just about perfect
FM/RDS is Future proof
• A general FM switch-off is unlikely for the next 30 years and probably it will never happen

RDS2 Significant Data extension
With RDS2 the Data capacity increases up to a factor 5 due to
• 3 Additional RDS carriers • Efficient coding of the new C Groups

RDS2 Improves mobile reception
In-car reception of long text messages up to 64 characters (RT Radio text) May take up to more than 1 minute before it can be displayed correctly
However repeating the same information on one of the upper carriers will increase The acquisition time and reliability significantly For RT (2A), RT+ and Long PS (15A)
The acquisition time of a Long PS LPS (15A) 32 bytes max UTF8 coded May take long
At the start of a new RT message content a series of 8-16 2A groups may be send On one of the upper carriers

Rich TMC service with RDS2
Average speed
< 5Km/h
< 15Km/h
Fluid
Today TMC is mainly motorway oriented.
For large major metropolitan areas like Paris,
Munich and London detailed and rich Traffic
Information is available like
Travel time and Speed information
Alerts for fast upcoming and unexpected Weather Changes may improve safety significantly Infrastructure is often present and information Is available.
With RDS2 this may become reality No data capacity constraints anymore

• Infrastructure for Traffic information has been improved drastically for large Urban areas
RDS2 a solution for urban traffic
• Location tables on detailed level exist for: Paris, London; Munich, Hamburg Berlin and many more
• RDS 2 has all capabilities to cope with this • From TMC To a rich added value Traffic Service
• TMC shows an ongoing Growth Recently TISA has certified 340 Location tables

Connected Car with RDS2
• RDS2 a perfect candidate in conjunction with
connected car developements like C-ITS
Coopererative Intelligent Transport Systems
to offer high level local Traffic (TMC) information
• RDS2 An integral part for Data communication for the connected car RDS is mature and everywhere
• To bring local Safety and Alert information to the driver.

RDS2 Time to Market
Essential for a proper Time to Market process is Time to Standardization
The RDS Forum is responsible for developing new ideas into applications And submit them to the IEC for standardisation.
The revised RDS Specification with parts 1-7 will be submitted to the IEC in November 2016
The right sense of urgency and a careful process using the expertise of its members is crucial for an optimal result
What is coming next?

RDS2 Time to Market-2
• RPP RDS Packet protocol for files up to 12kB Ideal for Station Logos
• NFM Non FM RDS Data protocol Streaming of RDS data next to Audio over other bearers like Internet
• Internet connectivity (IPv6 Address )
Recently a number of innovative new ideas have started in the RDS Forum To be developed towards maturity for submission to the IEC in 2017

Validation of RDS2
• RDS2 Sensitivity
• Define the test area and locations for RDS2 *
* Note Depends on availability of RDS test transmissions off air
Drive tests to be carried out by specialist teams. Monitoring and evaluation of the results.
• Adjacent signal conditions
• Reflections (Multipath distortion)
• In conjunction with HD-Radio
• Audio Quality
