Designing an extension API for bridging Ginga iDTV applications and home services

Resumo

This paper presents the implementation process for an API that integrates interactive digital TV (iDTV) applications and home network (HN) services, mainly concerning issues of the Brazilian iDTV model. The research in this field is important because it represents current trends on the use of iDTV opening many business opportunities. With the convergence of service providers, modern communication technologies and consumer electronics devices at home, new iDTV applications have emerged, particularly those that use the set-top-boxes (or digital TV sets) processing power to provide additional services, which extends the possibilities of interaction between the user and the connected home. To implement this platform, a known model, which considers aspects of the Ginga middleware and the Open Services Gateway Initiative (OSGi) framework, was used. The idea behind the API model is to export service objects from one side to another, allowing the development of two types of applications: the first one on the Ginga-J machine and the last one on the Ginga-NCL machine. The main goals of this paper are (i) presenting the use of free tolls to perform such integration and (ii) showing the most relevant aspects in the core of the two models. Finally, a basic step-by-step process is shown in order to build integrated iDTVHN real applications using this platform.
