In digital TV networks, IP is used more and more
to feed transmitter sites. Rohde & Schwarz has developed the R&S®DVMS-B40 option to provide comprehensive monitoring
and detailed analysis of these IP signals. This option monitors all relevant
quality parameters in the IP transmission. It performs a detailed check of up
to four transport streams simultaneously. If one of the transmitted transport
streams is faulty, the new option can extract this stream and transmit it to
the central monitoring station, also over IP. The personnel at the central
monitoring station can analyze the faulty transport stream in detail.
Graphically presented results make troubleshooting easier. The network operator
is able to immediately respond to signal failures or faults.
There are two models in the R&S®DVMS family. The R&S®DVMS4 (one HU)
can monitor the transmitted RF signals from up to four transmitters at a
transmitter site. RF modules are available for DVB-T, DVB-S, DVB-S2 and DVB-T2.
The R&S®DVMS1 is ideal for transmitter sites where only one RF or transport
stream signal needs to be monitored. This one HU, 1/2 19" unit can
accommodate one of the above modules. The R&S®DVMS family is extremely
flexible and can easily be scaled to meet users’ specific requirements, while
offering an excellent price/performance ratio.
The R&S®DVMS-B40 option allows connection to
up to 1 Gbyte electrical Ethernet networks. Optical IPs can also be connected
to the R&S DVMS using small form-factor pluggable (SFP) modules. Using the
simple network management protocol (SNMP), the R&S®DVMS can also easily be
integrated into central management systems.
The R&S®DVMS is a comprehensive monitoring
solution that enables network operators to detect all relevant faults at the
RF, IP and transport stream level. Thanks to the flexible hardware concept, the
R&S®DVMS can also be used for monitoring tasks in DVB-T2 networks.
