Patent attributes
In some embodiments, a method receives a manifest presentation description for a media presentation. The manifest presentation description includes an opportunity that requires resolution to determine supplemental content for the opportunity. A request to resolve the opportunity is sent where information for the supplemental content that is received from the request is inserted in an instance of the media presentation description. The method stores the information for the supplemental content in association with an identifier for the opportunity. An update to the manifest presentation description is received where the update includes the opportunity. The method retrieves the information for the supplemental content that was stored in association with the identifier for the opportunity and inserts the information for the supplemental content into the instance of the update to the manifest presentation description.
