<a name="watermark-procedure"></a>

**Note**  
The information in this section assumes that you are familiar with the general steps for creating a channel, as described in [Creating a channel from scratch](creating-channel-scratch.md). It also assumes that you have already set up the audio encodes (outputs) that will contain the watermarks.

**To create Nielsen watermarks**

1. On the **Create channel** page of the MediaLive console, choose the output group in the left navigation bar. Then choose the output. In the **Stream settings** pane, choose the desired **Audio** tab.

   In the **Codec settings** section, expand the **Additional encoding settings** section. Expand the **Additional settings** drop-down menu, and find the **Audio Watermark Settings** field.

1. Choose **Audio watermark**, then choose **Nielsen Distribution Type**. 

1. Choose the option that applies:
   + **Program content**: Typically, this option applies if your organization is a network broadcaster. 
   + **Final distribution**: Typically, this option applies if your organization is a broadcast affiliate or a cable network provider. 

1. If you want to include CBET watermarks: In the **CBET Settings** field, choose **Nielsen CBET**. More fields appear.

   If you want to include NAES watermarks: In the **NAES II and NW Settings** field, choose **NAES II and NW**. More fields appear.

   You can include both sets of watermarks in the same output audio.

1. Complete the fields as shown in the table.
