A-SMIL.org publishes specs on using SMIL to dynamically decide whether a media item within a playlist should or should not play. This functionality enables SMIL devices in

  • Limiting the “validity period” within which a media file is licensed to play
  • Defining items that only play on certain days of the week

IAdea’s SMIL-compliant media appliances fully support this SMIL feature. Users can easily control the playback behavior of any media item based on dynamic information at the media player.
