DV - Digital VideoDV - Digital Video
• 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.

Where did DV come from?Where did DV come from?
• Consortium of 55 companies developed DVC standard “Digital Video Cassette” – later to be called “DV”
• Frame-based compression scheme, with no motion compensation, unlike MPEG formats (similar to MJPEG)
• DV chip set built into cameras from Consumer machines (Sony HandiCam) to big DVCam to DVCPro

What is IEEE 1394?What is IEEE 1394?
• “Firewire” developed by Apple Computer – really a high-speed serial data bus– IEEE 1394 is the published specification for
the high-speed serial bus– First connectors showed up on Sony
camcorders in 1995 – called “i-Link”
• 400mbps over a distance of 4.5meters– Double twisted pair, 28 AWG wire– Longer distances possible using higher
gauges and slower data rates– 800mbps claimed for 2nd generation IEEE

• DV isn’t firewire; firewire isn’t DV– Other data may be transported over
IEEE 1394– DVTS requires high-speed serial bus to
transfer DV from the camera to the PC – What other serial input devices were/are
available on a PC?
• Historical footnote:– Early versions of DVTS required kernel
mods due to “slow” PC’s (Pentium II processors)
