4.1.4 Audio inputs and outputs
The audio inputs receive the audio signals to be encoded. They can be analog, or AES/3, or LAN audio (RAVENNA or
AES67 or Livewire). Each source can be encoded several times at different formats, and streamed to several destinations.
Audio samples decoded by X/LINK are played to the selected audio output. An audio output can be analog, or AES/3, or
LAN audio ( AES67 or RAVENNA or Livewire) .
Note that decoded audio samples can also be sent to internal audio buses, and audio buses can also be sources to be
encoded. This optional feature is used for transcoding IP audio streams.
4.1.5 Programs
In the encoding section of IQOYA X/LINK, a program is the encoding of one or several audio inputs. A program is then
defined by the following parameters:
●
the audio mode: mono, stereo, multi-channel.
●
the audio inputs that receive the signal to be encoded. The number of inputs is given by the audio mode. Stereo
and multi-channel modes refer to consecutive inputs.
●
the audio format: algorithm, bitrate, sampling frequency.
On the decoding part of IQOYA X/LINK, a program is the decoding of an audio source to the audio output. A program can
be composed of three decoding priorities, with automatic switching from a priority to another in case the audio source is
lost. Audio sources of the decoding priorities can be:
●
an RTP stream (raw RTP),
●
a HTTP stream (Icecast/Shoutcast),
●
audio inputs,
●
sound files or playlists stored locally.
