corresponding R, G, B (Red, Green, Blue)
components of pixels. If the difference is not bigger
than set value then such pixels are considered
identical.
Warning: Only when set to 0 the compression is
fully lossless
0 – 31

Bandwidth limit
Bandwidth limit in kbps for the Bandwidth limiter. If
this level is exceeded then codec will drop frames to
keep the bandwidth below the set limit.
Integer <
Output rate
10 – 1000000
9
Output rate
Defines maximum output rate at the RTSP server
level in kbps. This can be used to avoid spikes on the
network during the transmission.

4.2.1.5.
Monitor emulation
Monitor emulation is a feature that allows Video Grabber to “present itself as a monitor” when there
is no monitor connected to the ‘Video Output’ port. Possible settings are:
1.
None – monitor emulation is disabled
2.
VGA – Video Grabber emulates VGA monitor
3.
DVI – Video Grabber emulates DVI monitor
Additionally user can decide upon the custom EDID table that should be used by the Video Grabber for
the monitor emulation. However in such case the EDID data has to be uploaded first. (See the 4.2.5 on
page 38 for details on EDID related functions). Once EDID file is uploaded an option to use Custom
EDID becomes available.
