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
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.
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 … ?
It looks like this:
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)
DVTS Update

• DVTS Appliances
• Comet PMC - Fujitsu Research
• Mac-Mini
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
Mac-mini Web page
Mac-mini Web page
Mac-mini Web page
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.
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
