Ad policies specify such things as when to play ads (before or after a video), how often to play ads, details of the ad server URL, and setting key-values used for targeting. Ad policies can be set at the player level or the video level. These policies are set in the Brightcove Advertising module. Using the Advertising module, you can edit the ad request policies for your players or videos. If there is conflict in the policies, ad policies set at the video level override ad policies set at the player level.
