  1. BigVideo Project ResearchChannel/Internet2 DVTS - DV over the Internet Bob Riddle, Internet2 06 July 2004

  2. What if you could use your HandiCam? you could send & receive High Quality A/V • It doesn’t require funny, expensive machines • It doesn’t require involve IP issues (royalties) • It doesn’t require funny, expensive cameras • It does require a network capable of 30 mpbs all you need is a capable Network and … • a DV capable camera (HandiCam, DVCAM, DVCPro) with IEEE1394 (firewire) capability • DV receiver (DV Player, TV) that is firewire capable • Or an analog/digital converter(s) if using a non-firewire capable camera/receiver

  3. It looks like this:

  4. Things you might do … Korean Dance Performance: Sept 7,2003

  5. Things you might do … • National Internet2 Day • Several schools used DV/IP stream • Fall Member Meeting • instrumental rehearsal (museum, IU, CIM) • Video “Conference” • Both P2P and multipoint (using multicast) • Master’s Class – music instruction • Internet2 “Channel” Guide • Access Grid integration (APAN work)

  6. How can I get started? DVTS • Software encoding/decoding using the PC processor, NIC, etc. • Runs on number of platform, though Windows XP has the best GUI and uses PC monitor for display • Requires a firewire card if you are a “sender” (and receiver for non-WinXP) • Provided by DVTS Consortium & WIDE project http://www.sfc.wide.ad.jp/DVTS CometDVIP • Hardware implementation from Fujitsu Labs • Allows a “blackbox” like device to support DV/IP • Current video conferencing tests have been remarkable

  7. How can I get started (-cont-) take advantage of the “bigvideo” project work http://people.internet2.edu/~bdr/CometDVIP

  8. How can I get started (-cont-) take advantage of the bigvideo mailing list mailto: bigvideo@internet2.edu

  9. How can I get started (-cont-) Take advantage of the bigvideo CHANNEL GUIDE http://people.internet2.edu/~bdr/tvguide.html

  10. How can I get started (-cont-) • Multicast-enable your network • 30 mbps stream – for “broadcast” events the unicast client/server model won’t scale on your network • Use a tunnel, if you need to “bridge” multicast challenged networks (http://if.anu.edu.au/SW/rcbridge.html) • Take advantage of available multicast expertise • listserv@internet2.edu (subscribe wg-multicast in body) • Find some useful tools & test, test, test • http://dast.nlanr.net/Projects/Beacon/ • http://dast.nlanr.net/Projects/Iperf/

  11. What’s going on right now? Video-Conferencing exploration • Integrate echo-cancellation device • “build” a blackbox to support plug & play users • “build” an AG-like machine/environment (working with APAN/AARNet AG 2.2 efforts • “enhance” clients for non-technical users Streaming exploration • Exploring lip-sync problems related to WinXP clients • Potential OS X desktop client coming (Kaz) • Improvement of “xdvshow” client for Linux clients (Petr)

  12. What’s else is going on … Desktop iHDTV “One of the major goals of the ResearchChannel/I2 Working group is to broaden access to HDTV-quality resources over the Internet. The intent is to deliver "realism" to the desktop and create opportunities for new learning environments. ResearchChannel is pleased to announce progress and success in the delivery of HDTV over IP to your personal computer. Following in the footsteps of other ResearchChannel projects, including delivering studio-quality HD at 270Mbps, this lower bandwidth project at broadcast-quality HD (19.2Mbps) brings new possibilities for learning and other advanced applications using streaming video technologies.” Source: http://www.researchchannel.org/projects/i2wg/prj_ihdtv.asp

  13. What’s going on … (-cont-) Freely available client’s … (Raise your hand if you’d like to spend a few minutes working on some code …)

  14. where does DV/IP live in the video “neighborhood”? • H.323 • Multicast use removes need for MCU • Higher quality, lower latency a/v streams • Access Grid • Current integration work underway (APAN) • MPEG2 • No “IP” encumbrance, Higher quality, lower latency a/v streams • HDTV • Lower latency than compressed (20mbps) HDTV stream • Lower bandwidth than uncompressed HDTV stream • “Sweet spot” – if you have the bandwidth!

  15. You’re invited to “play” with us! • Join the DVTS Consortium • http://www.dvts.jp/en/ • Get the DVTS software • http://www.sfc.wide.ad.jp/DVTS • Purchase a CometDVIP card • bdr@internet2.edu • Join the bigvideo@internet2.edu project • wellings@cac.washington.edu • bdr@internet2.edu
