plcmt 6 means Screensaver

Added in AdCOM 1.0-202607. Shown when an operating system or app screensaver starts.

List: Plcmt Subtypes - VideoValue 6

When to send it

Send 6 for an ad shown when a device's operating system or an app enters its screensaver state after a period of inactivity, as smart TVs and streaming players do on their home screens. No content is playing when it starts. The value was added in AdCOM 1.0-202607.

Pair it with Video.playbackmethod 10 or 11, the idle-initiated methods from the same release, so buyers know whether sound is on. Buyers treat screensaver inventory as ambient: nobody chose to watch, and the viewer may not be in the room, so it is not priced like instream. It is confused with 5, which starts when the viewer pauses content, and with 4, the general no-content value sellers used for this inventory before 6 existed.

Example

{
  "imp": [
    {
      "video": {
        "plcmt": 6
      }
    }
  ]
}
