XIII.2 Further application examples
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)
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
XIII.5 Internet, Multimedia and Tele-services
XIII.6 Internet-information services
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
XIII.9 Tele-teaching via Internet
XIII.10 Tele-teaching / Tele-working: Modern Video-conference systems
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
System example: VTToolkit • Video Transmission Toolkit:

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