
“Color temperature”:
The color quality, expressed in degrees Kelvin(K), of a light
source. The higher the color temperature, the bluer the light. The lower the
temperature, the redder the light. Benchmark color temperature for the A/V industry
include 5000°K, 6500°K, and 9000°K.

“Contrast ratio”: The radio of the high light output level divided by the low light
output level. In theory, the contrast radio of the television system should be at least
100:1, if not 300:1. In reality, there are several limitations. In the CRT, light from
adjacent elements contaminate the area of each element. Room ambient light will
contaminate the light emitted from the CRT. Well-controlled viewing conditions
should yield a practical contrast ratio of 30:1 to 50:1.

“DVI”:
Digital Visual Interface. The digital video connectivity standard that was
developed by DDWG (Digital Display Work Group). This connection standard offers
two different connectors: one with 24 pins that handles digital video signals only, and
one with 29 pins that handles both digital and analog video.

“EDID”: Extended Display Identification Data – EDID is a data structure used to
communicate video display information, including native resolution and vertical
interval refresh rate requirements, to a source device. The source device will then
output the optimal video format for the display based on the provided EDID data,
ensuring proper video image quality. This communication takes place over the DDC
– Display Data Channel.

“Ethernet”:
A Local Area Network (LAN) standard officially known as IEEE 802.3.
Ethernet and other LAN technologies are used for interconnecting computers,
printers, workstations, terminals, servers, etc. within the same building or campus.
Ethernet operates over twisted pair and over coaxial cable at speeds starting at
10Mbps. For LAN interconnectivity, Ethernet is physical link and data link protocol
reflecting the two lowest layers of the OSI Reference Model.

“Frame”: In interlaced video, a frame is one complete picture. A video frame is made
up of two fields, or two sets of interlaced lines. In a film, a frame is one still picture of
a series that makes up a motion picture.

“Gamma”: The light output of a CRT is not linear with respect to the voltage input.
The difference between what you should have and what is actually output is known
as gamma.

“HDMI” - High – Definition Multimedia Interface: An interface used primarily in
consumer electronics for the transmission of uncompressed high definition video, up
to 8 channels of audio, and control signals, over a single cable. HDMI is the de facto
standard for HDTV displays, Blu-ray Disc players, and other HDTV electronics.
Introduced in 2003, the HDMI specification has gone through several revisions.

“HDSDI”: The high-definition version of SDI specified in SMPTE-292M. This signal
standard transmits audio and video with 10 bit depth and 4:2:2 color quantization
over a single coaxial cable with a data rate of 1.485 Gbit/second. Multiple video
resolutions exists including progressive 1280x720 and interlaced 1920x1080
resolution. Up to 32 audio signals are carried in the ancillary data.

“JPEG” (Joint photographic Expects Group): Commonly used method of lossy
compression for photographic images using a discreet cosine transfer function. The
