Arquitectura de Software para el Soporte de Comunidades Académicas Virtuales en Ambientes de Televisión Digital Interactiva

Abstract

In this paper software architecture scheme for supporting of virtual academic communities (CAV) in the context of the interactive digital television, is proposed and analyzed. The proposed architecture extends services defined until now within the e-learning environment, introducing concepts and applications of Web 2.0 through the consumption of the REST-JSON service scheme The scenarios supported by the architecture, the components and their interoperability that allow providing interactivity to different services in an environment of digital television, and the progress of its implementation in the laboratory, are described. In addition, two other services supported and deployed on the architecture are discussed: a message board and a chat room. The ability of the architecture to support flexible services, which can be associated or not to multimedia content of the CAV, is shown. This allows better management and efficient use of the return channel.
