# POIS signal conditioning
<a name="scte35-pois-conditioning"></a>

You can configure an AWS Elemental MediaLive channel so that your POIS server can perform *signal conditioning* on SCTE 35 messages that are in the content. Each time MediaLive encounters a SCTE 35 message in the content, MediaLive sends the message to the POIS server. The POIS server sends back a response to create a new SCTE 35 message, to replace the original message with different content, to delete the existing message, or to do nothing. 

**Note**  
To implement POIS signal conditioning, your organization must have access to a POIS server.
