Agenda iHDTV – High Definition Video Conferencing Platform Architecture Development History Research1 – Social Web Platform for e-Science Features Demonstration Roadmap 2/4/2014Title of Presentation, if desired2
iHDTV … What is it? Low latency, uncompressed multipoint HD over IP Project started in 1999 – 40Mbps, 270Mbps HDCAM, 1.5Gbps Format: uncompressed SMPTE 292M 4:2:2 1080i 60 Data rate total approx 1.5 Gbps per TX RX pair No compression to eliminate encode/decode latency Exploit R&E network bandwidth – No FEC Live camera feed and file playback HD SDI input -> HD capture card -> packetize -> IP Audio 6 channels Software mix-minus Separate packet stream – muxed with video at RX end
iHDTV … Hardware Hardware OS configuration Commodity Dual Proc or Core Duo PCI Express HD capture cards – TX Blackmagic Declink, RX AJA Xena Windows XP - investigating Linux capture card driver issue Latency Approx 120ms + network delay TX (2 frames), RX (2 frames) Hardware frame buffering feature of capture cards
iHDTV … Display Tiled screen - participants Sub-sampled 1.5Gbps/number of TX clients TX tiles multicast by venue service Tiled screen and layout constructed by RX client Full screen – primary speaker Controled by venue sevice Instructs sender to include TX remainder Multicast by venue service Total bandwidth full screen display + tiled display = 3Gbps
iHDTV … Network Need jumbo enabled bandwidth!!! Total bandwidth full screen display + tiled display = 3Gbps Packet replicators for multicast/unicast tunneling
iHDTV N-Way Venue Configuration Remote client site equipment: 2 RX iHDTV systems 1 TX iHDTV systems Persistent UW venue site equipment: 8 RX iHDTV systems 2 TX iHDTV systems Packet Replicators for multicast/unicast tunneling
iHDTV Remote Client
iHDTV Venue Service
iHDTV N-Way Conferencing iGrid, SC05, SC06
iHDTV Extreme: iGrid VISIONS05 iHDTV Extreme: iGrid VISIONS05
iHDTV and Optiportal – SC07 Integration with EVL Sage Runs as a Sage application using Sage libraries Software rendering on the RX end Audio managed by iHDTV Software rendering latency similar to hardware
iHDTV … Status … Work to Do … Status Persistent N-Way service - U Wash, CalIt2, U Mich, U Wisc Optiportal integration Open source – source forge, Apache Research Projects GUI – Operation, monitoring, stats,etc RX rendering on the desktop NTT i-Visto integration – ½ frame latency 4K – Red camera, Quad iHDTV transport Codec/bandwidth bridging service Interoperation – UltraGrid, et al More Information Mike Wellings Jim DeRoest
2/4/2014Title of Presentation, if desired14 Research1 is an online community that allows researchers to collaborate with peers, and share information and digital media with the general public.
15 Serve as a premier outlet for researchers to fulfill their public outreach requirements Foster interaction and communication between members of the public and researchers Provide a collaborative platform to teams who could potentially be geographically dispersed Primary Functions
16 Easily create a Project Hub that serves as a public-facing webspace for their work and/or a private collaboration area for team members Easily upload, store, tag, and publish digital media in multiple formats including video, audio, images and documents Publish a blog for the project to discuss ongoing work Interact with other researchers and the general public through project- and discipline-specific message boards, private messaging, grid toolkit, and IP-based videoconferencing Core Features for Researchers
17 Growing population of myspace-like collaboratory portals myExperiment, Sci-Vee, EcoSpace, CalIT2 Research.Intelligence, ourSpace… Grid, Cloud, favorite buzz word enabled YouTube for research Research1 – How is it different? Public facing, social interface to e-Research activities. Interoperate with e-Research portals – peer collaboration. Manage/deliver low bandwidth and high bandwidth essence objects Multi-discipline yet research focused vs. lost in theYouTube ether
