The Error Detection can be turned Off and On for each input
via check boxes and the entire module by radio buttons.
You will see the status on the left hand side “Input Bus Status”.
A grey “LED” shows that the detection is disabled,
green is OK, red indicates an error condition.
The bus status may be presented to external monitoring systems
via SNMP. The frame controller summarizes such status
information and generates SNMP traps for the frame as an entity
or may activate GPOs (if GPI/O module(s) are installed). The
SNMP manager may afterwards poll the modules for more
detailed information (e.g. which bus has an error? See SNMP
documentation for details). For inputs connected to unused
busses this detection should be turned off to prevent from
unwanted SNMP traps.
Encoder Parameter
Due to the different functions available for different encoding
formats, the accessible parameters may differ widely depending on
the encoder mode.
Encoder Mode [Dolby Digital, Dolby Digital +, HE-AAC v1/2, AAC]
Bitstream Packing Format [ADTS MPEG-2, ADTS MPEG-4, LATM/LOAS impl. SBR,
(only visible for AAC formats) LATM/LOAS expl. SBR, LATM in-band impl. SBR, LATM in-band
SBR, LATM out-of-band impl. SBR, LATM out-of-band expl. SBR]
For AAC encoding you may also define which MPEG-4 objet type
and multiplex technology must be used (see MPEG-4 Audio
standards for details).
Encoder Configuration Encoder 1 is fixed to 5.1
Encoder 2 [2.0, 5.1]
If both encoders are set to "Dolby Digital +" and the second
encoder is set to mode 2.0 it is possible to multiplex the streams
from the two encoders to form a single elementary stream
for DVB or ATSC encoding :
