SMIL-Based Wireless Multimedia Gateway Architecture And Platform

Abstract

In June 1998 the W3C released the SMIL that enables simple authoring of interactive audiovisual presentation with difference types of media combined together. However this is based on a wired wide-band network environment. Even version 2.0 of SMIL in August 2001 that provides limited functionality on a resource-constrained device named SMIL2.0 Basic, but it still has some limits by our investigation. So that, we propose WSMIL-based Wireless Multimedia Access that includes client, gateway and server sides. We wish to integrate those frameworks to provide friendlier interface for browsing multimedia presentation on resource-constrained devices. SMIL documents can be translated to WSMIL documents by the proposed gateway architecture with the CC/PP framework. By the WSMIL Filter in the gateway, Web-content providers only needs to provide one single SMIL document. Powerful devices (such as PC)as well as the resource-constrained devices can access and browse the contents adaptively.
