Adaptable software components in an electronic program/service guide application architecture for context aware guide presentation

This paper aims at providing architecture to create Electronic Program and Service Guide applications that can be adapted in real time. The architecture can be applied to generate computational code in different target languages, with a clear separation between style, structure and navigational aspects of Electronic Program and Service Guides. Following the proposed architecture and serving as a proof of concept, an Electronic Program Guide (EPG) was implemented for the reference implementation of the declarative environment of Ginga, the middleware of the Brazilian Digital TV System.
