Term Description
Contrast Contrast increases as the white point increases. Increasing the white
point creates a greater difference between white and black.
Contrast The ratio between white and black. The larger the contrast ratio the
Ratio greater the ability of a video device to show subtle colour details and
tolerate ambient room light.
There are two industry methods used: 1) Full On/Off contrast measures
the ratio of the light output of an all white image (full on) and the light
output of an all black (full off) image. 2) ANSI contrast is measured with
a pattern of 16 alternating black and white rectangles. The average
light output from the white rectangles is divided by the average light
output of the black rectangles to determine the ANSI contrast ratio.
When comparing the contrast ratio of video devices make sure you are
comparing the same type of contrast. Full On/Off contrast will always
be a larger number than ANSI contrast for the same video device.
Crestron Crestron RoomView Connected is built into projectors enabling direct
RoomView network connectivity for remote management of AV networks.
Crestron RoomView
management, remote monitoring and control of global AV networks
without any special wiring, hardware or programming. Once connected
to the network, classroom teachers and presenters can instantly control
any installed RoomView Connected™ projector. With no programming
required, AV and IT managers can globally monitor and control networked
projectors throughout a school, campus, or corporate enterprise.
Adding a Crestron control processor enables control of all AV
devices, lighting and environmental systems on the network from
any Crestron touch screen, Web browser and Apple
mobile devices including iPad™ and iPhone
By leveraging the Ethernet port on RoomView Connected projectors
and accessing RoomView, AV managers and support staff can
remotely take control of classroom technology, troubleshoot and
perform remote system diagnostics, track projector usage and
lamp life, log network activity and much more. Remote capabilities
allow efficient scheduling of projector power-off at preset times,
routine maintenance, faster response times to support calls,
alert notifications if projectors are disconnected, and broadcast
messaging of emergency alerts to all projectors.
Crosstalk Interference of an electrical signal by another electrical signal in close
proximity caused by its electromagnetism.
CRT Cathode Ray Tube.
dB dB or decibel is a measure of relative loudness. 0 dB is the threshold
of hearing. 60 dB is equivalent to normal conversation. 120 to 140
dB is the threshold of pain such as a jackhammer or gun shot. 10 dB
of change will double the loudness.
