The mapping rules may derive the values from various data sources to enable the media experience to be customized to the publisher, to the viewer, based on external events, or other dynamic data. At least some dynamic objects may be presented as overlays on an underlying video in a manner that seamlessly combines the dynamic objects with static media.
