3 The up side - TPEG ready TEC CAI TFP GLR PKI ETL TPEG FPI TPEG ready and waiting DAB/HDR Adaption Profiles SNI (WEA) 3

The up side - DAB Broadcast - Increasing availability DAB Broadcast UK National Public and Commercial France - Regional Roll out - Paris, Nice and Marseille.

4 The up side - DAB Broadcast - Increasing availability DAB Broadcast UK National Public and Commercial France - Regional Roll out - Paris, Nice and Marseille..8 regions all vehicles digitally enabled Germany - Commercial Multiplexes coming on line - 1 Aug 2011 National Commercial Mux Belgium - 100% DAB cover Others 4

5 The down side -Digital Switchover timescales UK Migration to Digital Digital Britain Report Digital Economy Act (April 2010) 5

6 Requirements for UK Digital Switchover Coverage Equivalent to FM 50% Listening Digitally ** Switch 2015 Impact assessment ** Listening based on ALL digital platforms not just DAB!! 6

7 Automotive DAB in UK Automotive is a key enabler of DSO 20% listening is in car ; only 1% of which is DAB France mandated fitment from 2013 Standard fit in UK vehicles by end 2013 Source:DRUK, RAJAR figures say 5% 7

8 Digital Radio Action Plan (July 2010) Ed Vaizey, minister for culture, communications and creative industries recently outlined the plan at the Consumer Electronics Conference in London. He pledged to work with car manufacturers to ensure that all new cars are fitted with digital radios as standard by the end of He also made reference to the 31 million vehicles that are currently driving on UK roads which will all be affected by the digital upgrade and reinforced the industry s message that there needs to be an affordable and easy conversion solution. SMMT chief executive, Paul Everitt said, Vehicle manufacturers are confident that it will be possible to meet the 2013 target for new vehicles, but further action will be required to prepare the heritage park for the ambitious 2015 timeframe. Key tasks include the development of more retro-fit options that meet agreed technical standards. It will also be important to assure customers that those installing this equipment are appropriately trained. 8

10 Effect on existing TMC services National, Regional and maybe some current local radio will migrate to Digital Only Reallocation of FM bandwidth to Ultra Local Stations Decision as early as years warning Switchover 2015 (+?) FM based TMC services in UK may STOP 10

11 Digital Traffic Provision Connected or Broadcast 2 UK TPEG DAB services ITIS - TEC, TFP and PKI - Nationally Services in vehicle within the year Still Many OEMs who are not yet ready for Digital Services Big Challenge to meet a 2015 switchover for new vehicles 11

12 Problems round the corner Problem for existing Vehicle Park Several Million recently new vehicles in field Majority will be less than 5 yrs old Problem also for OEMs with recently introduced vehicle platforms in production to be adapted Conversion DAB/TPEG? Connected? 12

13 Proposal for transition period To support existing in field and recent Nav systems by sending TMC encoded data over DAB to in car adapters. Adapters rebroadcast the TMC data as a standard TMC service using low power on board FM-RDS transmitter. New DAB-TMC receivers fitted in car can interface with existing NAV systems. - Reduced development in NAV system? 13

14 TMC over DAB - Problems to overcome National broadcast DAB sends all data to all receivers TMC receivers message limit is 300. Non relevant data displayed System performance Delivery speed Adapters need to buffer data Message Management without decoding content. Existing ETSI specification OK for new DAB-TMC decoders but not good for DAB-FM adapters. 14

15 TMC over DAB - Potential Workaround Create New TMC over DAB Spec. - TISA Use Case Raised Add Geoscoping data to each message - Include Ensemble Transmitter Information TII (MAIN_ID) in each message, with service linking info this will allow adapter to filter messages for their regional area ensuring relevant messages only are passed. Include message management - MessageID and Version Helps adapter update it s localised service without needing to know TMC Spec. 15

16 Summary Digital Switch will happen in UK, Not a definite timescale- uncertainty Not just UK Norway switch off FM broacast by 2017 Others likely to follow Choice of Connected or Broadcast If broadcast: TPEG or DAB-TMC? 16

17 OEMS / Device makers need to plan What delivery method? What content wanted? How to support in-field vehicles in warranty after Digital Switch over. How to modify recently new platforms to take data from DAB or connected.? Full support of TPEG delivered content? Or DAB-TMC 17
