a given color in any image is free from white. The less white in a color, the truer the
color or the greater its saturation. On a display device, the color control adjusts the
saturation. Not to be confused with the brightness, saturation is the amount of
pigment in a color, and not the intensity. Low saturation is like adding white to the
color. For example, a low-saturated red looks pink.
“Scaling”:
A conversion of a video or computer graphic signal from a starting
resolution to a new resolution. Scaling from one resolution to another is typically
done to optimize the signal for input to an image processor, transmission path or to
improve its quality when presented on a particular display.
“SDI”:
Serial Digital Interface. The standard based on a 270 Mbps transfer rate. This
is a 10-bit, scrambled, polarity independent interface with common scrambling for
both component ITU-R 601 and composite digital video and four channels of
(embedded) digital audio.
“Seamless Switching”:
A feature found on many video switchers. This feature
causes the switcher to wait until the vertical interval to switch. This avoid a glitch
(temporary scrambling) which normally is seen when switching between sources.
“SMPTE”:
Society of Motion Picture and Television Engineers. A global organization,
based in the United States, that sets standards for baseband visual communications.
This includes film as well as video and television standards.
“S-Video”:
A composite video signal separated into the luma (“Y” is for luma, or
black and white information; brightness) and the chroma (“C” is an abbreviation for
chroma, or color information).
“Sync”:
Synchronization. In video, sync is a means of controlling the timing of an
event with respect to other events. This is accomplished with timing pulses to insure
that each step in a process occurs at the correct time. For example, horizontal sync
determines exactly when to begin each horizontal scan line. Vertical sync
determines when the image is to be refreshed to start a new field or frame. There
are many other types of sync in video system.(Also known as “sync signal” or “sync
pulse.”)
“TCP/IP”:
Transmission Control Protocol/Internet Protocol. The communication
protocol of the Internet. Computers and devices with direct access to the Internet are
provided with a copy of the TCP/IP program to allow them to send and receive
information in an understandable form.
“USB”:
Universal Serial Bus. USB was developed by seven PC and telecom industry
leaders (Compaq, DEC, IBM, Intel, Microsoft, NEC, and Northern Telecom). The
goal was easy plug-and-play expansion outside the box, requiring no additional
circuit cards. Up to 127 external computer devices may be added through a USB
hub, which may be conveniently located in a keyboard or monitor. USB devices can
be attached or detached without removing computer power. The number of devices
being designed for USB continues to grow, from keyboards, mice, and printers to
scanners, digital cameras, and ZIP drives.
“VESA”:
Video Electronics Standards Association. A nonprofit number organization
dedicated to facilitating and promoting personal computer graphics through
improved standards for the benefit of the end-user. www.vesa.org
