The HbbTV Association has finalised and published its Operator Applications Specification.
It builds on HbbTV 2 and allows operators to provide an operator-branded experience as an application on TVs. The application acts as a ‘Virtual Set Top Box’, providing effectively all the functionality of a Set Top Box (STB) without the need to install one. An Operator Application (OpApp) can run immediately after the TV is turned on. To the user, the OpApp functions just like any other source on their TV, just like a cable input or an HDMI source. It can be used on any network supported by a connected TV including satellite, cable, terrestrial and IPTV.
