Reaching devices around an HbbTV television

HbbTV takes advantage of the opportunity to expand the broadcast experience exploiting the common media content. However, the time to reach the audience in a different way has come. Aware of the privileged position of the TV in the living room, manufacturers and marketplace app developers have fostered their own bunch of solutions to integrate the big TV display with the mobile ones, to consume broadband media but ignoring the broadcast traction potential. One major challenge of all these approaches is the resource discovery and association step, where different strategies have been employed. A TV content-centric approach opens new possibilities. First, the possibility to enhance the offer services scheduled on a time basis according to the broadcast signalling. Second, the awareness of a common media been played at the same temporal and spatial environment can support the discovery and association of surrounding handheld devices. This paper analyses the capacity of common visual and acoustic environmental patterns to build enhanced discovery and association protocols, concluding a multi-step combined solution as a suitable approach for broadcast-related second screen services.
