Create InBannerVideo Blocker

[karimMourra]

Problem:

The Video PMC has been made aware of a Publisher paint point consisting of SSPs delivering video creatives in Banner bids.
The Publisher is not aware that the Banner Ad contains a video, because the SSP delivers an HTML containing a video player. This results in a poor user experience on the publisher's site with no compensation, since the SSP is getting video CPM while paying for banner inventory.

Proposed solution:

• Introduce a InBannerVideoBlocker module that checks if a video is ever embedded in a display slot.
  • If video is ever embedded in the display slot once the HTML has rendered:
    • the module destroys the video element
    • the module notifies the publisher via Javascript callback, allowing the publisher to use another display bid.
    • The notice includes the SSP and the ad slot/GPID which the publisher can use for tracking and reporting
• Introduce a blockInBannerVideo config option to enable the InBannerVideoBlocker
• Include granularity options to allow the publisher to disable this feature for specific ad units or SSP Bid adapters.
  • this allows publishers to dedicate some inventory to InBannerVideo or to support InBannerVideo with trusted SSPs.

Feedback request

We would like to gauge interest from the Publisher committee before moving forward. We also welcome feedback on improvements that can be made to this proposed feature.

i think some of this is already part of the bid filtering module

@patmmccann is this the module you're referring to https://github.com/prebid/Prebid.js/blob/master/modules/bidResponseFilter/index.js ? I don't see anything for IBV

Attr has ibv

If video is ever embedded in the display slot once the HTML has rendered:

can you do this reliably? e.g. if it's embedded in a sub-iframe? is it easier to convince the involved parties to set the correct bid attributes, or to do video in a way that we can detect?

[dgirardi]

There may be content security policy or other iframe controls that control embedded media

We can dig into sub iframes if we have to.

I would prefer if everyone played nicely and set the correct attributes, but that doesn't seem to be the case given the feedback we've received. This was surfaced as a publisher pain point. Do publishers want this or not ?

Not if it's cross domain. More generally I think if the creative doesn't want to let you mess with it they have the advantage (unless there's some higher level browser APIs I don't know about, they have arbitrary code execution). So this approach would work to catch bids that "forgot" to set the right attributes, not those that actually don't want you to know it's video, and I'm wondering if it's easier to remind them to set attributes.
