Internet-information services XIII.6

XIII.7 Internet-information services

Internet and E-Commerce Client Marketing and Sales Advertising agency Engineering office Automaker Bank - Electronic Mail - Hypertext / WWW - Security aspects Secure online- payments - Delivery data, application forms - Electronic Mail - Complex documents - Online-videoconference - Cooperative work - Java Applets: dynamic loading of Code - XML (Extensible Markup Language) as exchange format for documents - Electronic/Multimedia Mail - Complex Documents - Hypertext/WWW XIII.8

Tele-teaching via Internet XIII.9

Tele-teaching / Tele-working: Modern Video-conference systems XIII.10

XIII.11 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
