  1. Perspectives

  2. XIII.2 Further application examples

  3. XIII.3 Tele-teaching WWW Server (Courseware) Lecture Internet / Scientific network / ISDN Cooperation in small groups Requirements: - Internet-/Intranet-Integration - Media-integration - Service quality => Multimedia and Tele-services Large image projection (Beamer, LCD-Display)

  4. XIII.4 Mobile Computing Production data Main office => Caching Maintenance technician Client ISDN Mobile access Requirements: - location independent communication - world-wide standards - very different performance and costs: GSM, ISDN, LANs Software-technical, automatic adaptation to each system environment Example: Access to picture data/compressed picture data/graphics/text

  5. XIII.5 Internet, Multimedia and Tele-services

  6. XIII.6 Internet-information services

  7. Internet-information services

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

  9. XIII.9 Tele-teaching via Internet

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

  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

  12. System example: VTToolkit • Video Transmission Toolkit:

  13. XIII.13 Mobile and Ubiquitous Computing

  14. XIII.14 Basic technologies

  15. XIII.15 Applied example: civil engineering, field work Large archives Video-conferences ISDN ATM Construction plans, urgent changes Construction Construction company A (Central Office) company A (Branch Office) Architect X.25 ATM ISDN Selected Construction plans Video-conferences GSM Construction supervisor GSM Material data, status data, deadlines building site Construction company B

  16. Associated infrastructure services Applications - Telematics - service (maintenance, field service) - integration of different devices in fabrication-environments, information systems or in household Middleware - adaptation - localization - supporting Software with numerous new special functions Networks - GSM, UMTS, IMT-2000, MBS - Wireless-LAN, Bluetooth, Hiperlan, 802.11, Ethernet - Networking of embedded devices

  17. Ubiquitous Computing • Mobile Devices ubiquitously • overlapping Mobile Networking • „Calm Technology“: processing procedures widely automatic and „invisible“

  18. Internet Scenario: fair visit Personal fair stall custodian corresponding to “user profile“ of the client Fair information system plans round tour between fair stalls Sensor checks Online-Ticket Internet- Ticketing; Planning fair round tour City information system points out the way to the fair Mobile Device buys Ticket -> Security requirements?? Remote Online Check-In to the Hotel; booking in the restaurant
