Goals • Create a media presence for research activity. • Provide high-quality and accessible resources for research information. • Encourage collaborative technology experiments between ResearchChannel participants to develop new methods of distribution.
Goal 1 - Create a media presence for research activity • Strategies: • Increase traditional satellite and cable tv distribution • Target marketing for retransmission • Create new partnerships for distribution
Current Number of Subscribers • 9.0 million - Dish Network • 9.1 million - Individual cable systems • 18.1 million - Total
Hours of Media Viewed per Month Combined Webcast andVideo On Demand Programs Hours
Regional distribution outside U.S. * Webtrends: October 2002 - 2003. U.S. is 75% of Total, this shows remaining 25%
Goal 2 –Provide high-quality and accessible resources for research information • Strategies: • Develop programming • Engage new participating organizations • Get funding for productions
Video Library Growth • 270 New Programs per year Average23 PremieresEach Month 1255 1158 1048 971 891 Programs 763 Program ArchiveCumulative Total 651 593 482 381 259 61
Strategies: • Integrate and automate traditional television and streaming Internet distribution. • Develop high-quality low latency interactive systems. • Implement meta-data and underlying architecture to make programming easily findable. • In general, support industry and ubiquitous vendor standards. • Provide the highest quality viewing experience.
Multicast: Experiment with vendor solutions for high quality distribution • Amnis • Videocharger • Video Furnace • VBrick • VideoLAN • DVTS
Delivering Reality: Internet HDTV • HD/IP >220 Mbps • www.ResearchChannel.org/dvd03 • HD Desktop Client at 19.2 Mbps
BIG Video:First steps in high quality low latency interactive experiences • SDI/IP – contribution feed quality • DV/IP • Plasma screen resolution/IP
BIG Video: DVTS - DV over the Internet • What is DV? • What is IEEE1394 (firewire) & why do I care? • What is DVTS? • Software from WIDE • Hardware from Fujitsu Research • What have we done with DVTS? • DanceQ, Virtual Briefings, other streaming • Video Conferencing, AG-like experiments
DV - Digital Video • Digital Video, put simply, is video that has been digitally sampled • Digital Video comes in many formats and data rates: • CCIR 601/SDI@ 270-360 Mbps @ 4:2:2 • Digital composite @ 95-135mbps • MPEG2 4:2:2P @ up to 100Mbps • High Definition – SMPTE 292M, ATSC rates, and MPEG2MP@HL 13-100Mbps • Streaming Video: Real, WM, Quicktime/Darwin/Sorensen, etc.
Where did DV come from? • Consortium of 55 companies developed DVC standard “Digital Video Cassette” – later to be called “DV” • Frame-based compression scheme, with no motion compensation, unlike MPEG formats (similar to MJPEG) • DV chip set built into cameras from Consumer machines (Sony HandiCam) to big DVCam to DVCPro
What is IEEE 1394? • “Firewire” developed by Apple Computer • really a high-speed serial data bus • IEEE 1394 is the published specification for the high-speed serial bus • First connectors showed up on Sony camcorders in 1995 – called “i-Link” • 400mbps over a distance of 4.5meters • Double twisted pair, 28 AWG wire • Longer distances possible using higher gauges and slower data rates • 800mbps claimed for 2nd generation IEEE 1394
Firewire … why do I care? • DV isn’t firewire; firewire isn’t DV • Other data may be transported over IEEE 1394 • DVTS requires high-speed serial bus to transfer DV from the camera to the PC • What other serial input devices were/are available on a PC? • Historical footnote: • Early versions of DVTS required kernel mods due to “slow” PC’s (Pentium II processors)
What is DVTS? Software from the WIDE project • Runs on FreeBSD, OSX, WinXP, Linux • Requires a IEEE 1394 PC interface • Requires a DV input • WinXP client permits desktop rendering of DV stream http://www.sfc.wide.ad.jp/DVTS
Hardware from Fujitsu Research • PCI card that does all the “hard-work” • http://journal.fujitsu.com/252e/now.html • http://www.comet-can.jp/index.html • http://www.comet-can.jp/Topics/2003-02-Ehime/snapshots.html • Supported on WinXP, Linux • Requires a Sony HandiCam compatiable DV input • Network stream is compatiable with DVTS software
What are we doing with DVTS? • Streaming applications • Virtual Briefings, Member Meeting, DanceQ • http://people.internet2.edu/%7Ebdr/CometDVIP • http://apps.internet2.edu/dvip.html • http://events.internet2.edu/briefings/dvts.html • Video Conference • Testing with UPenn, IU, Korea, UW • AG integration? (WIDE students, Internet2) • CometDVIP “MCU”, Desktop integration
