  2. Interactive HDTV (Current Status)

  3. Interactive HDTV (2020)

  4. Application Requirements Internet-based Receivers TV Devices HDTV Streams 1920x1080, 30fps, 20Mbps, MPEG2 format Customization of Content Configurable content (movie, email, web, games) Distributed Content Production Content Protection Interactivity and Flexibility Overlay Network Challenges QoS Provision Response time 20 ms for Interactivity High bandwidth to Homes/Campuses Overlay Reverse Multicast and Integration with Source-based Multicast Asynchrony of Content Heterogeneity of peers/proxies/end systems Real-time Software Solutions Interactive HDTV (Network Challenges)

  5. Collaborative Spaces Current Status • 2020 Application Requirements • Large Visualization Spaces for Distributed Simulations • Distributed Grid and Parallel Computation and Storage in Order of Hexa-bytes • Conferencing with 1000 and more participants to view and augment distributed experiments • Heterogeneity of Devices and Networks • Holography

  6. Collaborative Spaces (Network Challenges) • Throughput of end protocols such as TCP, SOAP, HTTP • Provision of very different QoS guarantees on Grid as on-demand, conversional, interactive application requirements meet • Real-time services for data processing inside network (e.g., scaling, trans-coding, low-pass filtering services) to deliver data over wired/wireless networks to large and small devices • Service routing, service composition

  7. Composite Near and Distance Education (Current Status)

  8. 2020 Application Requirements Composition of Smart Seminar and Lecture Rooms into distributed infrastructure to serve large number of on-campus and off-campus students Interactivity in Hot Spot Situations Device and Network Heterogeneity Mobility Multiple Educational Applications ranging from Multiple coordinated power-point presentations/video/votes/questions quizzes, electronic voting Office hour conferencing lecture on-demand retrieval electronic TA, Q&A Network Challenges Wireless Hot Spots in lecture and seminar rooms (addressing, resource allocation) Provision of QoS (bandwidth, delay guarantees) in Wireless Rooms Interference (infrared cameras, bluetooth mice and wrist-watches, 802.11 iPAQs) Programming of Networks, Devices and Applications in these environments End-to-end Delay and Bandwidth Provision to Remote Students Seamless switching between wire-line and wireless network protocol stacks and seamless switching between different wireless protocol stacks Network Security Composite Near and Distance Education
