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
™
HLS, Microsoft
™
Smoothstream, RTMP, MPEG DASH, Adobe ™ HDS and Nullsoft SHOUTcast™.
The Probe can be expanded through license options to monitor the T2MI protocol layer as found in
DVB-T2 networks.
The Probe can also be licensed with an SCTE 35 option that allows monitoring and logging of splice time
codes embedded in the transport streams.
1.2 How to Use This Manual
This User’s Manual is valid for software version 5.4 of the VB220, VB220-DMG and VB20 Probe.
Throughout this manual the term stream is often used rather than unicast or multicast. One stream may
consist of one or more services, and refers to one IP uni- or multicast (for Ethernet input) or one transport
stream (ASI, COFDM, QAM/VSB or QPSK/DVB-S2).
Chapter 2 PRINCIPLE OF OPERATION provides a simplified block-diagram overview of the probe.
Chapter 3 SAFETY lists safety precautions, and this chapter should be read prior to equipment installation.
