Content interactivity and television

To TV program viewers content interactivity means to be able to navigate seamlessly between TV programs and web-based content much as they do on the web.  To broadcasters content interactivity means to give viewers the opportunity to watch broadcaster-related content with a return path to the TV program.

A technology satisfying these needs has been developed by MPEG in a standard called Multimedia Linking Application Format (ISO/IEC 23000-18). It is a data format that describes, in a standard way:

  • The source content(TV program): content ID, start and end time of bridget validity, metadata etc.
  • The bridget(the link): metadata, information on how the bridget is presented to the viewer (during bridget validity) etc.
  • The destination content(where the bridget takes the viewer to): content ID, start and end time of destination content, metadata etc.

WimLabs has developed TVBridge, an end-to-end system for broadcasters to create bridgets and TV viewers access additional content. Watch the video and enjoy!

So many applications of MLAF are possible and here is a first list:

  • Education: while the lecturer or a documentary talks about a topic, a bridget pops up. The student/viewer can tap the bridget and know more about the topic
  • News: something important happens in an unknown place. By tapping the bridget media information about the place becomes available
  • Advertisements: Follow up to product placement, user-centric advertising, user-selectable product ads
  • Miscellanea: Access to multilanguage, Subscription based bridgets, Commentator tracks to a program, Program analytics
