Abstract

Multimedia applications for DTV systems can take profit of multiple exhibition devices to enrich the set of supported interactive applications. New applications in which viewers can cooperate besides being able to have its own navigation space without disturbing their neighbors in a common environment will now be possible. The NCL language allows developing such applications following a hierarchical model supported by its presentation environment called Ginga-NCL, by using a set of components in charge of orchestrating the several devices used in the presentation. This paper presents the mentioned support provided by the reference implementation of the Ginga-NCL middleware, stressing its architecture and illustrating the new possibilities opened by the multi-device applications.
