Japanese broadcaster NHK has confirmed that its broadcast-broadband service Hybridcast will officially launch on September 2.
The initial deployment, available to those with a compatible TV will offer viewers a mix of breaking news, weather, sports and financial information.
Pay-per-view and other on demand services will go live later in the autumn.
The use of tablet devices as a second screen, particularly as part of TV game shows, is also a part of the roadmap.
Initially Hybridcast is firmly in the connected TV market the transmissions will only be included on terrestrial broadcasts but use of other media is being considered.
Hybridcast takes advantage of the broadcast elements within HTML5.
