DAB Data Services (1)Opportunities• DAB is not only audio• DAB is a wireless, mobile, broadcast system suitable for:

Telematics (car services, navigation)Internet Services (Mobile Internet, Location Based App)Multimedia on the move (TopNews)

• Synergies with other media (GPRS, UMTS)

DAB needs a Flexible Service Platform

DAB Data Services (2)

Challenges• Beyond 3G: integration of networks

Flexible HW and SW PlatformFlexible and Competitive Range of Services

• Competition from other mobile (UMTS, DVB-T) and fixed networks (Internet)

• Increasing competition in the radio business (Internet Radio, MP3, etc)

• Transport using MOT Java Type (JAR)• Signalling and Profiling with FIG 0/13• Personal Java

• DAB Asynchronous Event based API

DAB Java: Advantage ...• Abstraction of the DAB System• Easy for system and user application (Xlet)

development• Large/Extensible Java Runtime API

(I/O, AWT, Swing, Net, etc)• Secure and Safe environment• Reducing cost for system and user application

development• Easy to add to other framework• Extendible platform for future/new applications

DAB Java: .. Costs

• Minimum software requirements are needed: CPU, memory, storage, etc

• OS (also if it is possible to have JavaOS)• Screen is needed for flexible graphics

applications• Porting DAB Java on a Java platform is a

medium effort task• Multimedia terminals
