There are standards such as HbbTV and MPEG-DASH available, but they meet these requirements only partially and require enhancements before they can be adopted by the industry. While HbbTV 2.0.3 is the latest version of the specification, it still has limitations in providing a seamless and personalized ad experience across broadcast and broadband. This demo showcases a real world, deployed and almost product ready implementation of Dynamic Ad Substitution for HbbTV Versions 1.5 and 2.0.X showcasing the feasibility for individual content replacements via broadband in broadcast environments.enDAIAd InsertionHbbTVDASstream eventsstreaming workflow optimizationadaptive bitrate streamingDDC::000 Informatik, Informationswissenschaft, allgemeine Werke::000 Informatik, Wissen, Systeme::006 Spezielle Computerverfahrenconference paper
