Using HbbTV and a second screen to link TV programs to related content on the Web

While parallel Internet usage to explore additional information while watching TV is on the rise, TV content owners face excessive costs and technological challenges to provide eased access to that information alongside their own content. Since viewers do not have access to the same background metadata as the content owner, they are often frustrated in their own searches. Linked Television is a concept for interlinked TV and Web content within a shared digital ecosystem under the control of the content owner. In this paper, we describe how we implement a prototype for Linked Television using a HbbTV device as main screen communicating with a second screen such as a tablet used by the viewer to easily access and browse information related to what is seen in the TV program.
