摘要： To control advertisement or other media content placement in content, content owners or other interested parties may include ad or media content placement metadata in the content item. Media content placement metadata may provide specifications such as a maximum media content (e.g., ad) duration, media content rating, media content size, payment information, placement location on a screen (i.e., for videos or images) and the like. The media content metadata may be extracted and used to retrieve matching media content such as advertisements for inclusion during play of a corresponding content item.
