The PaP (Picture and Picture) view shows up to three images of the
same size.
Microphones which use phantom power draw their electrical power from
the same cable as the audio signal. For example, if your microphone is
powered by a single cable, it serves both to power the microphone and
transmit the audio data. Microphones which have two cables, one for
sound and a separate power cable, do not use phantom power.
The PiP (Picture In Picture) view shows a video image in the main
screen, with an additional smaller image overlapping in the corner.
Typically, a remote presentation is displayed in the main part of the
screen, and the remote video is in the small image. If the remote endpoint
does not show any content, the display shows the remote video in the
main part of the screen, and the local presentation in the small image.
Point-to-point is a feature where only two endpoints communicate with
each other without using MCU/Media Server resources.
The PoP (Picture out Picture) view shows up to three images of different
size, presented side by side, where the image on the left is larger than the
two smaller images on the right.
See Dial Prefix on page 96.
A PTZ camera can pan to swivel horizontally, tilt to move vertically, and
optically zoom to devote all the camera's pixels to one area of the image.
For example, the XT Standard Camera is a PTZ camera with its own
power supply and remote control, and uses powerful lenses to achieve
superb visual quality. In contrast, fixed cameras like webcams only offer
digital PTZ, where the zoom crops the camera image, displaying only a
portion of the original, resulting in fewer pixels of the zoomed image,
which effectively lowers the resolution. Fixed cameras also offer digital
pan and tilt only after zooming, where you can pan up to the width or
length of the original camera image.
Q.931 is a telephony protocol used to start and end the connection in H.
323 calls.
QCIF, or Quarter CIF, defines a video resolution of 176 × 144 pixels (PAL)
or 176 x 120 (NTSC). It is often used in older mobile handsets (3G-324M)
limited by screen resolution and processing power.
Quality of Service (QoS) determines the priorities of different types of
network traffic (audio, video and control/signaling), so in poor network
conditions, prioritized traffic is still fully transmitted.
A recording of a videoconference can be played back at any time.
Recordings include audio, video and shared data (if presented). Users
