4.1 Working principles in “Program Distribution” mode of use
IQOYA SERV/LINK is a multi-channel IP audio codec. It allows at the same time:
● Encoding the incoming signals and streaming them over IP,
● Decoding IP audio streams to output channels
● Transcoding incoming IP audio streams
The number of audio inputs and outputs of the codec is defined by the licence (for instance SERV/LINK 16161
features 16 mono inputs and outputs).
The number of audio channels to be transcoded from the input streams is also defined by the licence (audio
buses).
