standards for base band 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
 “VGA”: Video Graphics Array. Introduced by IBM in 1987, VGA
is an analog signal with TTL level separate horizontal and
vertical sync. The video outputs to a 15-pin HD connector and
has a horizontal scan frequency of 31.5 kHz and vertical
frequency of 70 Hz (Mode 1, 2) and 60 Hz (Mode 3). The signal
is non-interlaced in modes 1, 2, and 3 and interlaced when
using the 8514/A card (35.5 kHz, 86 Hz) in mode 4. It has a
pixel by line resolution of 640×480 with a color palette of 16
