The illustrations and GUI screenshots used in this user’s manual will refer to VB220. They are equally
valid also for the VB20 and the VB220-DMG.
In subsequent text the word probe is used as a generic reference to VB20, VB220 and VB220-DMG.
1.1.3 Probe – Functionality
An IP-based network is fully transparent with respect to signal contents quality, provided that the IP
packets arrive, and provided that they arrive in time. The Probe therefore uses the patented MediaWindow
to allow monitoring at-a-glance of packet loss and errors in inter-packet arrival time. This way the operator
can conveniently ensure correct signal quality at IP-level.
The advanced Ethernet protocol analysis tool automatically detects all protocols carried over Ethernet
past the port the Probe is connected to, and it displays statistics like percentage utilization of the interface
and percentage of the different transported protocols. This gives the Probe a real-time sniffer capability.
The Probe allows the user to define a Return Data Path (RDP), using the regular video/data network or
the management network to return a stream. A faulty signal can then be further analyzed at the studio
premises, when necessary.
The recording functionality allows the user to record a stream, either triggered manually by the user or
triggered by a user defined alarm.
