What can I do with DVTS?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?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?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 … ?

Mac-mini DVTS ApplianeMac-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

A DVTS “Appliance” for normal peopleA 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!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
