In subsequent text the word Probe is used as a generic reference to VB20 and VB220.
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 analysed 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.
Full Service Monitoring (FSM) checks that vital system components like CA-servers are
active.
Optional Ethernet TR 290 monitoring allows the operator to check parameters like
transport stream sync and PSI/SI standards conformity. This option also performs
further PSI/SI analysis, making it possible to view PSI/SI contents. PID and service
bitrates are also continuously measured.
Optional OTT monitoring allows the operator to set up active testing of Over-the-top
type signals as found in adaptive bitrate streaming architectures. Formats supported
include Apple (tm) HLS, Microsoft (tm) Smoothstream, MPEG DASH and Adobe (tm)
