  1. DVTS Workshop Bob Riddle bob@internet2.edu

  2. Agenda • DVTS • Welcome - DVTS from 50,000 feet • DVTS Developers • Media streaming issues in Japan - Hiroshi Esaki • DVTS Update - Kazunori Sugiura • Multiple DVTS stream synchronization - Hisamatsu Tuyoshi • Dynamic Routing aggregation in Stream based infrastrucutre - Katsuhiro Horiba • Methods on unification of video streaming format using DVTS - Kazuhiro Mishima • Typical usage in Tokyo University of Agriculture and Technology - Takeshi Sakurada • DVGuide, DVTuner, DVTS Appliance(s) • Hands on Workshop

  3. What can I do with DVTS? • you can send & receive High Quality A/V • It doesn’t require funny, expensive machines • It doesn’t 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 • a computer with IEEE1394 (firewire) capability

  4. What is DV? • 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.

  5. What is firewire? • “Firewire” developed by Apple Computer • It is really a high-speed serial data bus • IEEE 1394 is the published specification for the high-speed serial bus • 400mbps over a distance of 4.5meters • Double twisted pair, 28 AWG wire • Longer distances possible using higher gauges and slower data rates • 800mbps for 2nd generation IEEE 1394 • DVTS requires high-speed serial bus to transfer DV from the camera to the PC! • Maybe USB 2.0 is a new possibility … ?

  6. It looks like this:

  7. What can I do with it? • National Internet2 Day • Several schools used DV/IP stream • Fall Member Meeting • Rehearsal (Indiana State Museum, IU, CIM) • Badnwidth matters! (UPenn Museum) • Video “Conference” • Both P2P and multipoint (using multicast) • Master Class – music instruction • Internet2 “DV Guide” • Access Grid integration (APAN work)

  8. DVTS Update • DVTS Developers • Media streaming issues in Japan - Hiroshi Esaki • DVTS Update - Kazunori Sugiura • Multiple DVTS stream synchronization - Hisamatsu Tuyoshi • Dynamic Routing aggregation in Stream based infrastrucutre - Katsuhiro Horiba • Methods on unification of video streaming format using DVTS - Kazuhiro Mishima • Typical usage in Tokyo University of Agriculture and Technology - Takeshi Sakurada

  9. DVGuide • http://db.arts.usf.edu/dvguide/listings.asp • DVTuner • http://vbvod.internet2.edu/ • DVTS Appliances • Comet PMC - Fujitsu Research • Mac-Mini

  10. Mac-mini DVTS Appliane is a $500 DVTS appliance possible? • Mac-mini - limit to a single firewire port • No muss, no fuss • No monitor, keyboard, mouse required • Configure, plug it in, then phone-home • Web browser used for control • example

  14. A DVTS “Appliance” for normal people • Affordable • Recognizable user interface • Ready for prime time • Internet2 test channel is evidence • May require breakout box, echo cancellation equipment … the same MPEG2 boxes, etc.

  15. Hands on Time! • Install DVTS on your machine • Play with the CometDVIP machine • Take Mac-mini DVTS for a test drive • Work on the hard stuff: • Multicast issues, testing, validation • Audio – quality, echo, mixers • Lighting – match investment to the event

  16. Questions? • Questions? • http://people.internet2.edu/~bdr/dvts/ Bob Riddle bdr@internet2.edu bigvideo@internet2.edu
