Abstract

This paper discusses how 3D objects, in special X3D documents, can be embedded into Digital TV middleware, aiming at providing 3D interactive content for both IPTV and terrestrial DTV systems. Particularly, the paper focuses on embedding 3D objects into Ginga-NCL, the declarative environment of the Japanese-Brazilian ISDB-TB terrestrial DTV middleware, and ITU-T Recommendation for IPTV services. Thus, we propose a well-defined interface that allows 3D objects to be declaratively embedded into NCL -- the declarative language of Ginga-NCL -- multimedia applications. Moreover, the proposed solution will allow for 3D objects to take advantage of the high-level abstractions of NCL to specify temporal behavior of 3D scenes, and contributes to the convergence process between different multimedia (2D and 3D) technologies.
