Sample Brightcove Player Prebid Plugin Integration - Prebid in Header

Overview

The Brightcove Player Prebid Plugin can be integrated on the publisher’s page in such a way that the pre-bidding can be executed in the header of the page before the Brightcove Player is loaded.

Advantages

  • Potentially lower latency in rendering selected ad; the reduction in latency is directly related to how long the prebid process is allowed to run.

Disadvantages

  • Requires publisher code both in the header to start the prebid process and also in the body to render the ad once the Brightcove Player is loaded.
  • Publisher must register the plugin on page - it cannot register the plugin in Brightcove Studio.

Caveats

  • There is no guarantee that the prebid process will complete before the Brightcove Player is loaded, so there may still be some latency.
  • If the Brightcove Player is being embedded in a cross-domain (unfriendly) iFrame, then the prebid process must occur in the header of the iFrame and not in the header of the page.

Sample Code

The following is a sample Brightcove Player Prebid Plugin integration that invokes Prebid in the header before Brightcove Player has been loaded.
