It is however possible to configure a couple of Video Grabbers to share their network interfaces so that
only two network connections would be needed to transmit the captured data from 3 or more devices.
This functionality is called ‘bridging’ and can be configured in the Bridging subsection of the network
section using the parameters described in the table below (check Figure 24 for parameter locations):
