The AVN-PSCO licence option for the AVN Portals adds the capability for a single stereo Opus encode or decode flow. The AVN Portals can provide up to a maximum of 8 stereo encode or decode flows at any one time. The option exposes a codec setting in the AoIP output dialog in the web UI and also allows the the unit to receive AoIP streams encoded in the Opus format. Encoder bitrates are selectable from the AoIP output dialog and can be set between a minimum of 4000 bps and a maximum of 512000 bps. The decoder automatically decodes any received Opus stream at any supported bitrate.
