An overview of Bigvideo desktop HD and DVTS multicast infrastructure
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: [email protected] 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 [email protected] (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!
