Hybridcast is an infrastructure system being developed by NHK, with a view to commercial use in 2013. This system combines broadcasting with the Internet, to enable a variety of TV-centered services.
At this year's NHK Science & Technology Research Laboratories Open Day, NHK exhibited prototype receivers, developed together with manufacturers, as well as the service concept.
If used in conjunction with sports broadcasts, updates about the players and the game can be synchronized with the broadcast timeline and superimposed on the screen.
