Delivery methods value 2 means Progressive

When to send it

Send 2 when the player plays a single media file, such as an MP4 or an MP3, while it downloads over HTTP. It is the most widely supported method and the default for most web and app video ads. The matching VAST delivery attribute is progressive.

Buyers with standard MP4 creative need 2, and audio ad files are usually delivered the same way. It is confused with 3, where playback waits for the whole file, and with 1.

Example

{
  "imp": [
    {
      "audio": {
        "delivery": [
          2
        ]
      }
    }
  ]
}
