This section provides an overview of the various technologies that SMART Bridgit software uses
when you share your desktop during a meeting.
SMART Bridgit software uses the following three types of technology to share screens during a
meeting.

best performance. It requires an installation which is automatically done if you have
administrator rights.

Mirror drivers behave unexpectedly on computers with Windows 7 operating
systems.

SMART Bridgit software reverts to using redraw hooks if it can't use mirror drivers.
Redraw hooks are automatically downloaded from the server when needed and
performs a screen capture every time something changes on the screen.

Four times
per second
capture
If SMART Bridgit software can't use either of the above technologies, it captures the
shared screen four times per second, compresses the image, and then sends it to the
recipient. This method offers the lowest performance, but it uses the lowest
bandwidth.
