Next generation systems
Requirements:
• adaptive, highly optimized and standard-conformant Videocodecs for different platforms H.26x and MJPEG
• “real time” transport system for different networks IP/RTP, N-ISDN (H.320), (Fast-/Gigabit-)Ethernet, ATM and Wireless LANs
• support of heterogenic environments corresponding to end-systems and networks
• uniform, configurable and integrated control components which are based on established Middleware-Standards
• consequent modular, freely configurable and object-oriented design
• integration of security mechanisms corresponding to administration and also for video-transmission

Associated infrastructure services
- Telematics- service (maintenance, field service)- integration of different devices in fabrication-environments, information systems or in household
- adaptation- localization- supporting Software with numerous new special functions
- GSM, UMTS, IMT-2000, MBS- Wireless-LAN, Bluetooth, Hiperlan, 802.11, Ethernet- Networking of embedded devices
Applications
Middleware
Networks
XIII.17
Ubiquitous Computing
• Mobile Devices ubiquitously
• overlapping Mobile Networking
• „Calm Technology“: processing procedures widely automatic and „invisible“

Scenario: fair visit
Internet-Ticketing;
Planningfair round tour
Sensor checks Online-Ticket
Fair information system plansround tour betweenfair stalls
Personal fairstall custodian corresponding to “user profile“of the client
Remote Online Check-In to the Hotel; booking in the restaurant
City information system points out the way to the fair
Mobile Device buysTicket
