BigVideo Project ResearchChannel/Internet2 DVTS/HDTV – Better than average Video over the Internet Jim DeRoest ( Director, Streaming Media) Michael Wellings ( Director, Engineering) Bob Riddle (Director, Nothing) 06 July 2004
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
It looks like this:
Things you might do … Korean Dance Performance: Sept 7,2003
Things you might do … � National Internet2 Day • Several schools used DV/IP stream � Fall Member Meeting • instrumental rehearsal (ISM: IU, CIM; NWS – UM) � Video “Conference” • Both P2P and multipoint (using multicast) • Master’s Class – music instruction • Internet2 “Channel” Guide • Access Grid integration ( APAN work )
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
How can I get started (-cont-) take advantage of the “bigvideo” project work http://people.internet2.edu/~bdr/CometDVIP
How can I get started (-cont-) Take advantage of the bigvideo CHANNEL GUIDE http://people.internet2.edu/~bdr/dvguide.html
What if I need help? take advantage of the bigvideo mailing list mailto: bigvideo@internet2.edu
Don’t forget … � 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/
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) DVTS Consortium • OS X, Linux desktop receivers, • IIGA “set-top” box for “normal” people
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!
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
