1. Bob Riddle, Internet2 24 March 2004 BigVideo Project Internet2/ResearchChannel DV/IP - DV over the Internet

2. What if you could use your HandiCam for Video Conferencing or for “broadcasting” events? 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. Other things you might do … Korean Dance Performance: Sept 7,2003

5. Other 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. where does DV/IP live in the video “neighborhood”?  H.323 – How is it different? Multicast use removes need for MCU Higher quality, lower latency a/v streams  Access Grid – can I use it with my AG? Current integration work underway (APAN/ANU)  MPEG2 – why not just use mpeg2? No “IP” encumbrance, Higher quality, lower latency a/v streams  HDTV - why not just use HDTV? Lower latency than compressed (20mbps) HDTV stream Lower bandwidth than uncompressed HDTV stream  “Sweet spot” – if you have the bandwidth

7. 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/DVTShttp://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

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

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

10. How can I get started (-cont-) Take advantage of the DVGuide “Channel” GUIDE http://people.internet2.edu/~bdr/dvguide.html

11. 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 ) http://if.anu.edu.au/SW/rcbridge.html Take advantage of available multicast expertise  listserv@internet2.edu (subscribe wg-multicast in body) listserv@internet2.edu Find some useful tools & test, test, test  http://dast.nlanr.net/Projects/Beacon/ http://dast.nlanr.net/Projects/Beacon/  http://dast.nlanr.net/Projects/Iperf/ http://dast.nlanr.net/Projects/Iperf/

12. What’s going on with DV/IP 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/Korea AG 2.1 efforts “enhance” clients for non-technical users Streaming exploration Exploring lip-sync problems related to WinXP clients syncing ( memory mapped VGA buffers … Radeon 9800 Pro XT) Potential OS X desktop client Improvement of “xdvshow” client for Linux clients

13. What’s going on in related areas? 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.asphttp://www.researchchannel.org/projects/i2wg/prj_ihdtv.asp

14. 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 …)
