Hybrid broadcast broadband TV implementation in java based applications on digital TV devices

HbbTV (Hybrid broadcast broadband television) is an open standard for network-enabled TV sets. It is a European initiative for providing both broadcast and broadband content delivery on TV sets and set-top boxes. HbbTV standard adds a new aspect to the experience of watching TV by providing interactivity to plain TV broadcast. The content to be delivered is the HbbTV application. HbbTV application presents a combination of web content and live digital TV broadcast. In this paper we present one solution for integration of HbbTV standard into Java applications which are being developed for DTV devices. We present modifications to the underlying operating system, JavaScript plug-ins, and DTV-related modules which are necessary to be implemented in order to have the HbbTV features enabled. We also present performance measurement comparing our solution to an embedded Linux one and one commercial solution.
