For monitoring the syntax of the transport stream, measurements are performed
in line with the ‘Measurement guidelines for DVB systems (ETR 290). Refer to
Measurement Functions.
All first-priority parameters and two second-priority parameters (Transport_error
and CRC_error) are assigned an LED on the front panel. See Figure 4–14. All
other second-priority and third-priority parameters are indicated by the OTHER
LED. See Table 2–1 on page 2–3.
Figure 4–14: Front-panel LEDs indicating parameters
The parameters are cyclically checked. Any error detected is signaled by the
respective LED on the front panel or indicated in the MONITORING/STA-
TISTICS Menu or MONITORING/REPORT Menu. Individual parameters can
be selected and deselected for monitoring in the MONITORING/PARAMETER
GROUP menu. Limits for the PCR values and PSI and SI tables can be specified
in the MONITORING/LIMITS menu. The limits with the standardized values
for DVB and MPEG can be predefined in the MONITORING/DEFAULT menu.
