Constraint-based media content delivery over heterogeneous networks and devices

Mobile and wireless technology has attained a great penetration in the market during the recent years. The need to deliver media content to a great variety of mobile and wireless devices is delineated as the indisputable future trend. This is instigated by the fact that wireless networks can now support the quality requirements of media streaming delivery, while mobile devices are able to present a variety of media content. This paper presents the Enamorado architecture that allows decoupling the development of mobile devices from advances in content formats and implements an intelligent system that selects the most appropriate content format in terms of for example device limitations, end-user preferences and current network conditions. This is particularly important, in cases which demand maximising the number of admitted users, without compromising the user's quality standards. Finally, this paper presents a case study to present how the system's intelligence is applied in a real network.
