3.8.2

AdParameters

TOC Schema Some ad serving systems may want to send data to the media file when first initialized. For example, the media file may use ad server data to identify the context used to display the creative, what server to talk to, or even which creative to display. The optional <AdParameters> element for the Linear creative enables this data exchange. The optional attribute xmlEncoded is available for the <AdParameters> element to identify whether the ad parameters are xml-encoded. If true, the video player can only decode the data using xml. Video players operating on earlier versions of VAST may not be able to xmldecode data, so data should only be xml-encoded when being served to video players capable of xml-decoding the data. When a VAST response is used to serve a VPAID ad unit, the <AdParameters> element is currently the only way to pass information from the VAST response into the VPAID object; no other mechanism is provided.
