101: Troubleshooting SCTE-35 DAI A Quick Guide

Sometimes things just don’t work. You’ve rebooted, run reports, and you just need to pause. Here are some steps to troubleshoot SCTE-35 DAI issues:

1. Check for SCTE-35 markers: The first step in troubleshooting SCTE-35 DAI issues is to check if the SCTE-35 markers are being inserted into the video stream correctly. You can use a tool like SCTE-35 Analyzer to check if the markers are being sent at the appropriate times and if their contents are correct.

2. Check your ad server: If the SCTE-35 markers are being sent correctly, the next step is to check your ad server. Ensure that the ad server is sending ad inventory to the video player at the appropriate times and that the ad creative is correct.

3. Check your video player: If the ad server is sending ad inventory correctly, the issue may be with your video player. Ensure that your video player is configured correctly to receive SCTE-35 markers and that it is capable of processing them correctly. Check the video player logs for any errors or warnings related to SCTE-35 processing.

4. Check for network issues: If the SCTE-35 markers, ad server, and video player are all working correctly, but the ads are still not showing up, there may be a network issue. Check for any network issues that may be preventing the video player from receiving the ad inventory correctly.

5. Test with different devices and platforms: If the issue is only occurring on certain devices or platforms, test with different devices and platforms to identify if it is a device-specific issue.

6. Contact your ad server or video player provider: If the above steps do not resolve the issue, contact your ad server or video player provider for further assistance. They may be able to provide more targeted troubleshooting steps or identify any issues specific to their platform.

101: What is ESAM Scripting for YouTube & SCTE DAI?

First, what is SCTE? (pronounced scut-e). The Society of Cable Telecommunications Engineers (SCTE) is a professional association that offers education, certification, and standards for the telecommunications industry. SCTE serves as a technical and applied science leader, providing training and certification programs in broadband, cable networks, and digital video. It has a diverse membership of professionals, including engineers and technicians, who work in the cable and telecommunications industries.

Next, what is ESAM? ESAM stands for Event Signaling and Management. It is a protocol used in cable networks to provide advanced notification and management of network events. ESAM allows for the delivery of messages that can be used to signal events such as program start and end times, emergency alerts, and other network events. It is an important component of the CableLabs Enhanced Content Specification, which is a set of technical specifications used in digital TV networks. ESAM is designed to enhance the functionality and interoperability of networks, improving the viewing experience for subscribers.

ESAM scripting for SCTE:

1. Identify the video content that needs to be marked up with SCTE markers. These could be ad breaks, chapter markers, or other significant events in the video.

2. Use an ESAM editor tool to create the ESAM script. There are several tools available, such as ESAM Creator and ESAM Builder. These tools allow you to create, edit, and validate the ESAM script.

3. Define the SCTE markers in the ESAM script. Each marker should include the timecode, duration, and type of event. For example, an ad break marker could be defined as a “cue-in” event with a duration of 30 seconds.

4. Validate the ESAM script to ensure that it is compliant with the SCTE specification. Use the ESAM editor tool to run the validation process and check for any errors or warnings.

5. Save the ESAM script and upload it to your YouTube account. You can do this by selecting the video content in your YouTube Studio dashboard, navigating to the “Advanced” tab, and uploading the ESAM script in the “Content ID” section.

6. Review the video content to ensure that the SCTE markers are working correctly. You can use the YouTube player to test the markers and make any necessary adjustments to the ESAM script.

By following these steps, you can create an ESAM script for YouTube SCTE that will help you manage and monetize your video content more effectively.

An ESAM script is an XML-based file that contains information about events or markers that occur in video content. These markers can be used for a variety of purposes, such as indicating ad breaks, chapter markers, or other significant events in the video.

Here is an example of an ESAM script for a dynamic commercial SCTE marker in XML format:

“`xml
<?xml version=”1.0″ encoding=”UTF-8″?>
<ESAM xmlns=”urn:ietf:params:xml:ns:esam:1.0″>
<EventSignal Time=”00:05:00.000″ Duration=”00:00:30.000″ Type=”Commercial”>
<Metadata>
<MetadataItem Name=”AdType”>Dynamic</MetadataItem>
<MetadataItem Name=”AdID”>1234</MetadataItem>
<MetadataItem Name=”AdTitle”>Example Ad</MetadataItem>
<MetadataItem Name=”Advertiser”>Acme Corp</MetadataItem>
</Metadata>
</EventSignal>
</ESAM>
“`

In this example, the ESAM script includes a “Commercial” event signal that occurs at the 5-minute mark of the video and lasts for 30 seconds. The metadata associated with the event signal includes information about the ad type, ID, title, and advertiser.

By using ESAM scripts like this one, video content creators and distributors can manage and monetize their content more effectively, while providing a better experience for viewers.

Broadcasting Standards: Utilizing AI with SCTE-35, SCTE-104

SCTE markers are metadata tags that are inserted into a video stream to signal specific events or actions, such as ad insertion points. DAI stands for Dynamic Ad Insertion, which is a technology that enables the insertion of targeted ads into live or on-demand video streams. Users can now elect to use or interact with AI bots like GPT-3.5/GPT-4 to even further automate these processes.


There are several SCTE standards that define SCTE markers for different use cases. For example, SCTE-35 defines markers for digital program insertion (DPI) and SCTE-104 defines markers for ad insertion. The specific SCTE markers used for DAI will depend on the implementation.

AI can help the process of dynamic ad insertion by analyzing data to identify patterns and make predictions about viewer behavior. Here are a few ways AI can be used:

1. Predicting viewer preferences: AI can analyze data about viewer behavior, such as which ads they tend to skip, and use that information to predict which ads will be most effective for a particular viewer.

2. Optimizing ad placement: AI can analyze data about viewer behavior to determine the optimal placement of ads within a video stream, such as which ad formats are most effective at different points in the video.

3. Targeting ads to specific audiences: AI can analyze data about viewer demographics and behavior to identify specific audience segments and deliver targeted ads to those segments.

4. Creating personalized ads: AI can analyze data about individual viewers to create personalized ads that are more likely to be effective.

Overall, AI can help make the process of dynamic ad insertion more efficient and effective by using data to make smarter decisions about ad placement and targeting.
