playbackmethod 7 means Continuous Playback

The player keeps playing further media on its own until the viewer stops it. An AdCOM addition, not in OpenRTB 2.5.

When to send it

Send 7 when the ad plays inside a player that moves from one item to the next without the viewer acting: an autoplaying playlist, an up-next queue, or a generated stream that runs until the viewer stops it. The value is not in the OpenRTB 2.5 table; it comes from the AdCOM list.

Buyers use 7 to recognize sessions where the viewer chose to start watching at some point but did not choose the current item. Binge viewing of episodes on CTV is the common case. It is confused with 1: both start without interaction, but 7 tells the buyer that the content around the ad was queued automatically.

Example

{
  "imp": [
    {
      "video": {
        "playbackmethod": [
          7
        ]
      }
    }
  ]
}
