Abstract
AbstractA common issue on live sports TV broadcasts happens when a viewer hears a neighbour screaming a goal before watching it on his TV. Similarly, viewers will also have a disruptive experience if a second screen application, designed to present information synchronised with the live TV broadcast, displays information beforehand. This paper presents a simple and universal synchronisation mechanism for second screen mobile applications, which does not rely on automatic content recognition, but rather on user feedback to help users achieve a pleasant and effective second screen experience. Results from user tests helped validate our approach, as users were able to synchronise a mobile application with a simulated live TV broadcast, with different delays.KeywordsSecond screenDelaysLive TV broadcastsUser experienceSports
