QMSIP/DVB/MPEG-2Quality Measuring System

2© 2012 Tebkom GmbH & Co. KG

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 allmeasured values

• Carrier ID analysis

Introduction


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 fedinto a report generator

Scanning Function


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

logicaland timingerrors

Transport Stream 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

Data Services Monitoring


Continuous monitoring of IP streams Service Analysis Port and Protocol Monitoring

Data Services Monitoring cont'd


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, ETR101290measurements, PCR accuracy, table repetition rates

• Report function of measuredparameters
