In this lesson, we'll look at how StreamCat responds to stream state events to update a channel's state or publish a VOD asset for a previous broadcast. If you recall from lesson 1.4, StreamCat uses an Amazon EventBridge rule to listen for various state change events related to our Amazon IVS channels. This EventBridge rule triggers an AWS Lambda function, and that function persists and updates database records as necessary. In this lesson, we'll focus on how StreamCat handles the following events:

- Stream Start
- Stream End
- Recording Start
- Recording End
