Application 4 - Mediaport 200 With Hardware And Software Codecs And Dsp Processor - Extron electronics MediaPort 200 User Manual

Connect MediaPort to/from the hardware video codec
1. Connect the Aux Out of the MediaPort to the input of the video codec. This may be the
microphone input of the video codec, although preferably it should be able to receive a
line level signal. Check the user guide of the video codec to find the appropriate input
and settings.
The MediaPort Aux Out sends the microphone signal to the video codec. Doing so
allows the same microphone to be used with the MediaPort only, the video codec only,
or both simultaneously.
2. Connect the line output of the video codec to the MediaPort line input. This will route
the hardware codec audio to the sound reinforcement system in the room, and also
to the far end of the soft codec conference in the case where hardware and software
conferences are bridged.
Application 4 – MediaPort 200 with Hardware and Software Codecs and DSP
Processor
This is an application for soft codec conferencing in a room that also has a hardware video
codec, in addition to a DSP processor that adds multiple microphones with distributed AEC.
Either software or hardware conferencing may be used independently at any time, or both
may be used simultaneously bridging both hardware and software codecs into the same
conference.

For this application, the MediaPort must be configured for use with an external AEC
processing device. In Extron PCS, navigate to the
