NetSense
NetSense is a proprietary Radvision technology which optimizes the video quality according to the
available bandwidth to minimize packet loss. As the available bandwidth of a connection varies
depending on data traffic, NetSense's sophisticated algorithm dynamically scans the video stream, and
then reduces or improves the video resolution to maximize quality with the available bandwidth.
Packet Loss
Packet loss occurs when some of the data transmitted from one endpoint is not received by the other
endpoint. This can be caused by narrow bandwidth connections or unreliable signal reception on
wireless networks.

The PaP (Picture and Picture) view shows two images of the same size, presented side by side.
PiP Video Layout
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
Point-to-point is a feature where only two endpoints are communicating with each other.
PoP Video Layout
The PoP (Picture out Picture) view shows up to three images of different size, presented side by side.
The image on the left is larger, with two smaller images on the right.
