Building on HbbTV 2, the specification allows TV operators, in partnership with TV manufacturers, to provide an operator-branded experience as an application on TVs. This application acts as a virtual set-top box (STB), providing effectively all the functionality of a traditional 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. OpApp can be used for any network type supported by a connected TV, including satellite, cable, terrestrial and IPTV.

The OpApp specification describes how the HbbTV browser can run both HbbTV broadcaster applications and operator applications at the same time. It specifies how operator applications are discovered, installed and how they can replace the TV’s native UI, including access to the TV’s remote control keys. The OpApp specification assumes that deployment of a certain operator’s application is subject to a bilateral agreement between the operator and the TV manufacturers.

Preparations for the OpApp trials are now underway in various countries; the first of these trials are expected to launch early 2018.

“The HbbTV Association is pleased to publish the specification for OpApps, knowing that we will improve customer satisfaction and user experience,” said Klaus Illgner, chair of the HbbTV Association. “The benefits will be realised across the board with manufacturers, broadcasters, operators and content producers, making the overall viewing experience more sophisticated and tailored to the consumer. The OpApp specification is a significant achievement with active participation across the entire value chain, resulting in a balanced specification that serves a well-understood market need with an experience that consumers will love.”
