HTML5 is driving a strong trend towards interoperable Web-based applications, enabling a wider range of devices to run this kind of applications. The key challenge of next-generation media applications is to federate cooperative devices to provide multi-device experiences overcoming current second screen solutions within the connected TV industry. There is a gap on the experience of users, since they perceive devices as isolated pieces of applications when they would prefer to have a single experience through multiple devices at the same time. This paper proposes a unified methodology and a common specification over Web Components for the adaptation of a single application, seamlessly running different instances on one or more devices simultaneously, according to the multi-device context of the user and the specific features of the devices. The solution presented in this paper extends current Web standards towards an interoperable architecture and offers broadcasters and media application developers the possibility to easily design applications that will automatically provide a unique consistent experience across the connected devices. The architectural design is targeted to be included in the roadmap of the standards.

“…The support for content (such as scripts, Lua, JPEG, PNG, and MPEG) is guaranteed by the Adapter, a component located on Ginga Common Core. Ginga-NCL also provides a device support mechanism, mainly related to sharing multimedia content among iDTV and mobile devices (Soares et al, 2009). A summary of the procedural/declarative technologies available for the middleware specifications presented before is depicted in Table 1.…”

Among the most promising uses for the interactive digital TV (iDTV) are the ones that enable TV sets to work as the central processing unit of a house. With the convergence of communication technologies and electronics devices in the home environment, a wide range of interactive applications have emerged, allowing to deliver new services to the user. The iDTV processing power has been expanded to support applications that interact with other electronic appliances in the smart home environment, performing the same role of a Home Gateway. Following this goal, this paper discusses the convergence of iDTV with home network at the software level, which facilitates novel combined iDTV home control experiences for users as well as new applications for businesses. Some models that implement convergence of open technologies for working with iDTV applications (DASE/ACAP and MHP middleware) and standards for managing services in a home network (UPnP, DLNA and OSGi framework) are presented. After that, we identify the most relevant features for our country to propose a new collaboration model supported by the Open Services Gateway Initiative (OSGi) and the Brazilian reference middleware, Ginga. The design and implementation of software elements of the model is presented, modifying as little as possible core components of the two platforms and exploring the new Ginga capabilities, related to the procedural (Ginga-J) and declarative (Ginga-NCL) environments. Our work is unique because it combines Ginga with OSGi in a way that is transparent for application developers, while at the same time exploiting the declarative part of the Ginga middleware, thus allowing developers to easily write mixed iDTV home control applications. At the end, we built some validating scenarios for both platforms, allowing Ginga iDTV applications (Ginga-J xlets or Ginga-NCL scripts) to manage services of electronic devices in an integrated Ginga-OSGi home network.
