IMPROVING THE USER EXPERIENCE BY WEB TECHNOLOGIES FOR COMPLEX MULTIMEDIA SERVICES

摘要

In this paper we address the accessibility to advanced networking functionalities and media rendering using a new framework. The objective of proposing this new framework is to make advanced services accessible for heterogeneous and limited devices. The context of this work concerns digital homes where several multimedia services exist and their use requires complex configurations and the ability to handle advanced networking operations. This required ability is not satisfied for handheld devices that are heterogeneous in terms of software and hardware capabilities. Indeed, even advanced mobile terminals do not support, at least natively, networking operations such as the multicast, services discovery and multimedia streaming with different protocols. In order to improve the user's experience in such environments, we focus on the Web accessibility and the adoption of the HTTP protocol that are nowadays supported by the majority of heterogeneous terminals such as mobile phones, TVs and game boxes. In order to demonstrate the feasibility and the validity of our framework we consider, as a digital home architecture, the Digital Living Network Alliance (DLNA) environment. We show that even if the existing architecture and multimedia/networking services are complexes, the proposed framework simplifies the architecture for the user and guarantees the delivery of an accessible and adapted response.
