VGA
VGA defines a video resolution of 640 x 480 pixels.
Videoconference
A videoconference is a meeting of more than two participants with audio and video using endpoints.
Professional videoconferencing systems can handle many participants in single meetings, and multiple
simultaneous meetings, with a wide interoperability score to enable a wide variety of endpoints to join
the same videoconference. Typically you can also share PC content, like presentations, to other
participants.
Video Fast Update (VFU)
Video Fast Update (VFU) is a request for a refreshed video frame, sent when the received video is
corrupted by packet loss. In response to a VFU request, the broadcasting endpoint sends a new intra-
frame to serve as the baseline for the ongoing video stream.
Video Layout
A video layout is the arrangement of participant images as they appear on the monitor in a
videoconference. If the meeting includes a presentation, a layout can also refer to the arrangement of
the presentation image together with the meeting participants.
