title: VAST 2.0 mid-roll and overlay implementation
body: <p>We are implementing into our video player the VAST 2.0 png/jpeg banner overlay and the mid-roll video advertisement.</p>
  
  <p><strong>My question is:</strong> From where the time information comes when (during the movie or series episode watching) the mid-roll video should be played or the overlay banner should be displayed. I was expecting the <code>VAST XML</code> has already that information included, but it seems that it should be either player decision or it comes from other source - e.g. it is specified within the movie metadata downloaded from OTT server.</p>
  
  <p><strong>Second question:</strong> What is the typical mid-roll video behaviour? Is the advertisement played in specific point in time, which means when user jumps in video (using FF/RW on his remote control) I have to play mid-roll (this can be pretty annoying) or I simply count the time the user watches the video and when it is over defined value the mid-roll video is played.</p>
