Silence detection parameters for the decoding priority
● First channel only: only the first channel is processed.
● Second channel only: only the second channel is processed.
PLL Read/Write
Set to Yes in most of the cases. It allows synchronization of the incoming IP audio to the
sampling clock, thus guaranteeing a constant delay.
It has to be set to No when samples must ne be modified between the encoder and the
decoder (this requires that the encoder and the decoder have clock sources having the
exact same sampling frequency)
Serial data destination Read/Write
In case serial data are tunneled in-band, select the COM port to output them. COM ports
are available if the RS232 ports hardware option is present.
Routing of tunneled status data:
Status data indexes
Read/Write
Select the GPOs that will reflect the tunneled GPIs statuses.
Select the GPI status by clicking on its index, and enter the GPO number that will reflect
the GPI.
Make sure the selected GPI indexes match the GPI numbers set in the IP service
parameters of the SERV/LINK that sends the stream.
Routing of tunneled status data:
GPO inversion mask
Read/Write Check the box under a GPO so that it reflects the inverted status of the tunneled GPI.
Priority Source Parameter Type Description
Disable upon silence detection Read/Write IQOYA can also automatically disable the decoding priority in case of silence detection
in the audio source. The priority can then be enabled again via the WEB site, or via
SNMP.
Input signal for silence detection Read/Write The parameter “Input signal for silence detection” allows defining on which source
signal the silence detection is applied. Possible choices are:
