3 DVB-H DMB DAB+ DRM+ / HD-Radio DRM DVB-T WLAN/Internet DVB-C UMTS / 4 G DVB-S S-DAB And all that s digital radio? W. Berner July 2nd 2008 LFK 3

4 Looking into the future In several year s time Analog FM has been replaced by a digital system DAB / DAB+ / DMB are succesfull DVB-T with advanced standard (MPEG4, DVB-T2) W. Berner July 2nd 2008 LFK 4

5 Market Shares Today Tomorrow Analog Digital Transition Period XY Time W. Berner July 2nd 2008 LFK 5

6 Some simple questions What are suitable transmission systems? How many radio channels will we have? What can we do with these channels? W. Berner July 2nd 2008 LFK 6

7 Radio: Coverage Areas Pan-european National Regional Local W. Berner July 2nd 2008 LFK 7

8 Local Radio Small coverage area High market share required General interest programmes Limited competition within the local scene Economic constraints Narrowband system required W. Berner July 2nd 2008 LFK 8

9 National Radio Large coverage area Small market share required Special interest programmes possible Heavy competition desired Broadband system well suited W. Berner July 2nd 2008 LFK 9

10 Which terrestrial systems? DVB-T DAB / DAB+ / DMB DRM+ UHF VHF, L-Band VHF (Band II) DRM < 30 MHz Only very little market share expected W. Berner July 2nd 2008 LFK 10

11 System-Capacity in terms of radio-programmes DVB-T DAB+ DRM No. of radio-programmes in a single multiplex (64 kbit/s per stream) W. Berner July 2nd 2008 LFK 11

12 Summary 1 Local Radio: Small multiplex National Radio: Large Multiplex DVB-T, DAB offer large multiplexes They do not support local radio A digital narrowband system is required DRM+ (?), HD-Radio (?) W. Berner July 2nd 2008 LFK 12

13 Assumptions Digital System in VHF Band II DRM+ or HD-Radio DAB+ / DMB in VHF Band III Radio via DVB-T in UHF 2% - 5% of total capacity (87,5 107,9 MHz) ( MHz) ( MHz) 64 kbit/s per stream W. Berner July 2nd 2008 LFK 13

14 No. of digital Programmes VHF, Band II, FM, analog VHF, Band II VHF, Band III UHF Grand Totale Digital Dividend W. Berner July 2nd 2008 LFK 14

15 Other Systems : WLAN / Internet For inhouse use WLAN-router connected to DSL or cable Portable radio > 5000 stations worldwide Distribution cost are limiting market share W. Berner July 2nd 2008 LFK 15

16 Other systems: Satellite, Cable DVB-S Hundreds of radio programmes S-DAB Dozens of radio programmes System operating in L-Band DVB-C Dozens of radio programmes W. Berner July 2nd 2008 LFK 16

17 Other Systems: Mobile UMTS / 4G / LTE Many programmes on a point-to-point basis Limited transmission capacity W. Berner July 2nd 2008 LFK 17

18 All-digital world Many many programmes Matched to the customer s desire Format Special interest programme General interest programme Technical System (Transmision) indoor, outdoor fixed, mobile W. Berner July 2nd 2008 LFK 18

19 Summary 2 Terrestrial: Analog: Digital: Very limited Number of Radio Channels FM: 15 Large Number of terrestrial Radio Channels > 100 Else: More channels via Satellite, Cable, Internet, Mobile W. Berner July 2nd 2008 LFK 19

20 Economic constraints No. of listeners remains constant No. of radio channels increases significantly Less revenue per channel Threat to commercial broadcasters W. Berner July 2nd 2008 LFK 20

21 Many terrestrial radio channels Unique capabilites: One to Many Indoor, portable, mobile reception Technically limited cell size W. Berner July 2nd 2008 LFK 21

22 Opportunities Some traditional linear radio channels Non-linear services Push-services Local interactivity Services for groups, not individuals Receivers with storage capabilities W. Berner July 2nd 2008 LFK 22

23 Summary 3 Many radio channels Competing transmission systems Linear channels ( traditional radio ) Non-linear channels giving additional revenue Local Interactivity Hard times for broadcasters W. Berner July 2nd 2008 LFK 23

24 Radio in an all-digital environment Make the best of it! Good Luck! W. Berner July 2nd 2008 LFK 24
