Arquitectura para el Despliegue del servicio de Video bajo Demanda de IPTV, apoyada en Interactividad y Sistemas de Recomendaciones

Abstract

This paper presents an alternative architec- tural solution for the deployment and support of the VoD (Video on Demand) service for television content on IPTV (Internet Protocol Television). This alternative integrates support of interactive services like wikis, chat, blogs and recommender systems with item based approaches, collaborative and hybrid. The architecture is described in different views like this: deployment, components and dynamic, based on a specific scenario. Unlike other ar- chitectures, this solution facilitates the convergence of standards and open technologies of Web 2.0 like Web Services,Services, REST (Representational State Transfer) and XML (Extensible Markup Language), which is consistent with the current trend on the Web to allow interopera- bility between independent software applications. From a set of tests concluded that it is possible to obtain a good performance in terms of response times in a real web during stress situations. As to bandwidth, the servi- ce can display all of the functionality on access speeds currently offered, considering that the architecture is designed to unmanaged networks therefore not assured QoS.
