Next generation systemsRequirements:• 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

Ubiquitous Computing

• Mobile Devices ubiquitously

• overlapping Mobile Networking

• „Calm Technology“: processing procedures widely automatic and „invisible“
