Metadata
The Metadata maybe inserted in the USER bits of the PCM signal(s) on
the C8k audio busses. Here you can select from which bus it should be
read.
PCM An independent digital stereo (or 2Ch) audio signal (PCM or encoded)
may be taken from the c8k bus to compensate for the Dolby E encoding
delay.
Delay The module provides a 2ch delay (up to 4 frames) to compensate for the
Dolby E encoding delay.
To C8000 System Bus The encoder output may be assigned to the C8k busses. It is fed to the
external BNC output as well.
Enable Bus Driver You may turn off (tri state mode) all bus drivers for installation to prevent
conflicts with modules already in service.
External Output BNC The Dolby E encoded bit stream is sent out via an unbalanced AES3
output in parallel to the C8k audio bus
Metadata Source Preset :
The parameters to setup the Dolby E encoder and the program
Metadata are defined manually. You may also load a Preset edit these
parameters and store them as a Preset again.
Bus :
The Metadata for the Dolby E encoder are extracted from the USER
bits in Metadata Subset format of one of the incoming PCM signals
external (RS485) :
The Metadata for the Dolby E encoder are received by the 9-pin Sub D
connector at the front side of the module in Dolby E format.
Error Detection The serial audio data from the frame bus can be monitored for proper
positioning of an Error-Flag. A bad Error-Flag is an indication that
there is disturbance upstream (input signal, input module,
DSP module).
The Error Detection can be turned Off and On for each input from the
bus. You will see the status on the left hand side: “Input Bus Status”.
A grey “LED” shows that the detection is disabled. While 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 “modulesStatus” for more detailed status information per input
(see SNMP documentation for details).
Metadata Reversion Last used :
Mode If a Metadata error is detected from the source, the encoding process will
continue with “last used” parameters
Stop encoding :
The encoder will stop encoding in case of a Metadata error from the input
