Delivery Type

The delivery type determines how the video is downloaded during playback. Either progressive or streaming.

Why do we test it?

With progressive delivery, the video is actually downloaded to the user's device. It starts playing as soon as the necessary data is available. Streaming delivery requires a streaming server that only sends the part of the video that is currently watched. For most use cases, progressive delivery is the standard. If you're working with CTV or live-streams, the delivery type should be set to streaming.
