LinkedTV player

We develop the LinkedTV player as a Web-based toolkit with support for multiple screens on different device types. A HbbTV variant is planned. The current implementation also supports remote control or gesture control interaction with the TV content (“main screen”).

The LinkedTV Player in year 2

The player streams the seed video from the original source onto the “main screen” and synchronizes on playout the video annotation information from the LinkedTV platform being displayed on a “companion screen”. Concepts are highlighted as the associated TV program fragment is active, and on selection the viewer accesses links to related Web content (enrichments). In the current player implementation, the detected entities showed on the second screen will always be grouped into three different layers by dividing entities based on “who, what, where” to identify respectively persons, objects and locations. The player can be seen in action in our Hyperlinked Documentary demos.

The Springfield multiscreen toolkit

The player is driven by a toolkit for synchronising content across screens, called Springfield.

We developed a concept where an application can be independent of how many screens are involved
and can in fact dynamically react to changes in the amount and types of screens attached to
the application. We currently support all HTML5 based desktop browsers, android phones and tablets as well as Apple (iOS) phones and tablets. Developers can program using any J2EE toolchain (we use Eclipse and Tomcat/Apache) use the normal compile and deploy tools (using the jar and war standards). The main difference is that unlike normal wars that need to be deployed to a J2EE application server you now deploy the application to a newly designed deployment area inside a Springfield cluster.

Client server model

The Springfield multiscreen toolkit is available to developers from the LinkedTV partner Noterik. For more information:
