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.
