Measurement Functions
MTD200 MPEG Test Decoder User Manual
2–3
Overview of All Measurement Functions
The measurement functions of the MPEG test decoder fully comply with the
recommendations contained in the DVB Measurement Guidelines (ETR 290) for
the analysis of MPEG-2 transport stream syntax.
Table 2–1 shows an overview of all measurement functions of the MPEG test
decoder and information on error indication, either as a cumulative message
(LED) or as a detailed error message in the Monitoring Statistic or the Monitor-
ing Report menu on the LCD or OSD. Refer to MONITORING / STATISTICS
Menu on page 4–12 and MONITORING / REPORT Menu on page 4–13.
In addition to the measurement functions shown in Table 2–1, the MPEG test
decoder also calculates the following values from the transport stream multiplex:
Total transport stream data rate [MBit/s]
Data rates of all individual programs in the TS multiplex [Mbit/s]
Data rates of all elementary streams of the individual programs in the TS
multiplex [Mbit/s]
Data rate for null packets
Data rate for PSI/SI table
NOTE
. The data rates of programs and single streams calculated by the MTD200
are the gross rates of the programs and single streams. Packet headers and
possible adaptation fields are considered in the measured value.
The transport stream data rates measured are displayed on the LCD or OSD in
the DECODER / SELECT PROGRAM menu (see page 4–21).
