ABSTRACT

The increasing performance of networks allows today the display of TV news bulletin and others multimedia contents via an Internet connexion. We describe in this paper, a system called ARM which enables the integration of multimedia streamed contents into a web page. This system is composed of an XML based syntax language called ARM, that helps to describe multimedia presentation. The navigation between documents of the presentation is achieved through an inheritance principle. Our system is composed of a lecteur on the client side that handle the users interaction. The actual navigation process in multimedia presentations is mainly based on simple link and like HTML and multiple links like XLink. This approaches when medias are streamed didn't take into account a real fluid navigation. It is not possible, for example, to enlarge a region that displays a video without restarting this media from its beginning. The navigation by inheritance preserves the continuity of streamed medais according to the user's interactions. We also presents our application of this approach : a Web on demand TV.
