The following parameters define the audio source associated with priority 1. It is possible to declare two additional priorities
by clicking on the button
The parameters listed for a decoding priority depend on the selected source "Type": IP service, File, Playlist, Audio input.
Read/Write
This parameters allows selecting a secondary output to duplicate the decoded audio.
When the primary output is an AoIP output (like AES67/Ravenna), the secondary output
can be an analog or AES3 output.
If a software option for transcoding channels has been installed, it is possible to select an
internal audio bus as a secondary output, when the primary output is set to an analog or
AES3 output. This serves in the following cases:
Description
In case the codec is configured to decode an IP audio stream and at least one backup is defined, you can configure the
backup switching criteria.
IP stream loss duration , expressed in ms, is the duration of absence of the stream. When this condition is encountered
on priority 1 or priority 2, IQOYA automatically switches to the lower priority.
The minimum value for this duration is the jitter value set from the Receive page.
This value, expressed in ms, is the duration of presence of the stream after it has been lost. When this condition is
encountered, IQOYA automatically switches to the higher priority where the stream is recovered.
These two criteria apply to the main received IP stream as well as to the backup IP stream.
During the stream recovery process, if a received packet is followed by a packet's absence duration larger than this "IP
stream absence duration", the stream is considered as absent. This value (in ms) should be lower than half the "IP stream
recovery duration".
If the value is set to 0, this parameter is ignored..

●
The audio that is decoded to an audio output can at the same time be routed to
an audio bus, in order to be re-encoded and streamed.
●
The audio decoded to the analog or AES3 outputs, is to be duplicated to both the
analog and AES3 outputs (the parameter Analog / AES duplication must be set to
Yes).
