DVM3001C02

5. GLOSSARY

CCVS

Composite color video signal. Standard definition composite analog video signal. This
signal carries synchronization, luminance and chrominance information. The two most
common formats for encoding are PAL and NTSC.

SD-SDI

Standard Definition - Serial Digital Interface. A serial digital interface capable of
transmitting standard definition television signals with bitrates of 143Mbit/s,
177Mbit/s, 270Mbit/s or 360Mbit/s.

SDI

Serial Digital Interface. A standard used for the transmission of uncompressed video
signals that can also include audio and time code signals.
