Backup switching criteria
Program Parameter
IP stream loss duration
IP stream recovery duration
IP stream absence duration
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.
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.
This parameter "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..
