Installation Guide for ConferenceSHOT AV Enterprise-Class Conferencing System

Glossary

AEC
Acoustic echo cancellation. Audio processing that subtracts the far-end (speaker) audio from the sound
that your microphone picks up.
auto white balance
A setting that allows the camera to manage color adjustments automatically.
backlight compensation
A setting that reduces contrast to adjust for bright light behind the main subject of the shot.
bandwidth
Data transfer rate (bits per second) for the stream. In some cases, using a high bandwidth can slow
down other network traffic. On networks with very low bandwidth, video issues may result. Streaming at
a lower resolution or frame rate can reduce bandwidth usage.
chroma
A setting that adjusts color intensity.
detail
A setting that adjusts image sharpness. If detail is set too low, the image may appear unrealistically
smooth – like an episode of Moonlighting.
DHCP
Dynamic Host Configuration Protocol. A network management protocol that assigns an IP address to a
device automatically when it is connected to the network.
DIY
Do It Yourself. As in, "You can copy information from this document to create a DIY room guide
customized for your conference room." Yes! You can do that! In fact, the "Info for DIY Room Guides"
document is specifically designed for you to adapt and customize.
EasyMic
Vaddio's proprietary connectivity standard for conferencing microphones.
echo cancellation
Audio processing that subtracts the far-end (speaker) audio from the sound that your microphone picks
up.
far end
(conferencing) A location in the conference other than the one where you are. Far-end video is what
you typically see in a conference – the people at the other end of the call.
Field of View (FOV)
How wide the video image is. Vaddio measures horizontal field of view. Some manufacturers use
diagonal field of view, which yields a bigger number for the same actual image area. Tilt your head to
one side and diagonal FOV will make sense.
flombodulator
A technically complex item the name of which you can't recall at the moment.
frame rate
The number of output video frames per second. Different outputs (such as the IP stream and the USB
stream) may use different frame rates. For streaming, higher frame rates use more bandwidth.
