The initial deployment, available to those with a compatible TV will offer viewers a mix of breaking news, weather, sports and financial information.

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.
