VAST (video ad-serving template)

An XML schema developed by the IAB that allows in-stream video ads (ads that are displayed in the video player, like those found on YouTube videos) to be served from video ad servers and played in video players across a number of websites, or publishers, and on numerous devices (desktop, mobile, tablet, etc).

VAST was adopted as an industry standard to address the compatibility issues between video ad servers and video players located on websites.
