# Including SCTE-35 markers
<a name="including-scte-35-markers"></a>

SCTE-35 markers indicate where downstream systems can insert other content (usually advertisements or local programs). You can include SCTE-35 markers in transport stream (TS), DASH, HLS, and CMAF outputs.

AWS Elemental MediaConvert puts SCTE-35 markers into your outputs in one of two ways:
+ The service passes markers through from your input to the output. For more information, see [Configuring SCTE-35 marker passthrough from your input](passing-through-scte-35-markers.md).
+ The service inserts markers at the points that you specify in an Event Signaling and Management (ESAM) XML document. For more information, see [Specifying SCTE-35 markers using ESAM XML](specifying-scte-35-markers-using-esam-xml.md).

Regardless of which way you put in the SCTE-35 markers, for outputs that have them, you can optionally do the following:
+ You can have the service blank out audio and video during the ad avails indicated by the SCTE-35 markers. For more information, see [Configuring ad avail blanking](ad-avail-blanking.md).
+ For HLS outputs, you can have the service include SCTE-35 information in your output HLS manifest. For more information, see [Including SCTE-35 information in your HLS manifest](including-scte-35-information-in-your-hls-manifest.md). MediaConvert doesn't write SCTE-35 information to DASH manifests.
**Note**  
MediaConvert does not process information from input manifests.

By default, the service doesn't pass through SCTE-35 markers from your input. When you set up your job to pass through markers from the input or from an ESAM document, by default, the service doesn't include SCTE-35 information in HLS manifests or do ad avail blanking.
