Measurements of key parameters of satellite transponders carrying DVB signals, including a frequency scanning function, ETR101290 analysis, carrier parameters, examination of DVB table information, BER values, fill factors, idle rates plus IP analysis

1. QMS
IP/DVB/MPEG-2
Quality Monitoring System

2. Introduction
 Complete and flexible solution for monitoring of
DVB based transmission systems
 Product family with 3 different models and several
options
 Main functions:
• Automatic carrier scanning function (in DVB-S/S2 version)
• Physical layer measurement (signal level, bit error rates, quality of
reception)
• In-depth ETR101290 analysis of Transport Stream
• IP data decapsulation and IP flow monitoring
• Flexible and customizable
report generator on all
measured values
QMS - Quality Monitoring System 2

3. Scanning Function (DVB-S/S2 version)
 Automatic frequency scan on a given orbital
position
 List of downlink frequencies with symbol rates and
error correction rates (FEC rates)
 Definition of parameters (minimum/maximum
symbol, frequency range) possible
 Analysis results are fed
into a report generator

4. Transport Stream Monitoring
 Continuous Monitoring of MPEG Transport Stream
• Measurement of errors according to ETR101290
• Measurement of packet timing and PCR timestamps
 Detection of standard violations
 Detection of logical
and timing errors

5. Data Services Monitoring
 Services: Continuous Monitoring of data services (meta data) of
data transmissions via DVB carriers for QoS and efficiency purposes
• Service Analysis (TCP, UDP, ...)
• Port and Protocol Monitoring
• IP-flow Analysis
 Stored data per flow
• PID
• Services:
- IP version
- Encapsulaton type (MPE, ULE, GSE)
- Applications (www, HTTPs, SMTP, ...)
• Source/destination IP address
• Total bytes/packets

7. Online Carrier Analysis
 Line-up support tool
• Carrier parameters selected out of an automatically generated list
or manually entered
• Measurement of carrier parameters (signal level, Eb/No, ...)
• Monitoring of services in a
hierarchical style extracted
from PSI/SI tables, ETR101290
measurements, PCR accuracy,
table repetition rates
• Report function of measured
parameters

8. User Interface
 User-friendly GUI (Web-interface) for configuration
and complete system management
 Access to the database using pre-defined queries or
advanced queries using SQL commands

9. Report Generator
 Service overview:
Listing of services per user-defined time periods
 Detailed service list:
I.e. name, ID, service provider, allocated PIDs, bandwidth, percentage
of overall transponder bandwidth, service type
 Quality parameters:
Signal level, Eb/N0, ES/N0, estimated Channel and Viterbi BER
 Non-compliance report:
Summary of non-compliances measured during a measurement period
 Fill rate report:
Fill factor (data vs. null/idle)
of an input stream
 Export functions:
HTML, PDF, CSV
