Field facts

Path: imp.video.playbackend
Object: Video
Type: integer
Requirement: Optional
Added: OpenRTB 2.5
Values: AdCOM list Playback Cessation Modes
Spec section: 3.2.7

How it is used

It matters mostly for web players outside the main content, where scrolling away can end the ad. Value 3 matches the floating or sticky behavior that the plcmt definition of Accompanying Content allows.

Allowed values

Value	Meaning
`1`	On Video Completion or when Terminated by User: Playback runs until the ad completes or the viewer stops it, even if the player scrolls out of view.
`2`	On Leaving Viewport or when Terminated by User: Playback stops when the player leaves the viewport or the viewer stops it.
`3`	On Leaving Viewport Continues as a Floating/Slider Unit: When scrolled away, the player detaches into a floating or slider unit and plays on until completion or the viewer stops it.

Example

Where the field sits in a payload, with everything else left out:

{
  "id": "req-1",
  "imp": [
    {
      "video": {
        "playbackend": 1
      }
    }
  ]
}

Common mistakes

Sending 1 for a player that stops when scrolled out of view, which overstates how often ads complete.
