System architecture of WebSmart : a web-oriented synchronized multimedia authoring system Xu, Yue

Abstract

Embedding multimedia contents such as audio and video into a Web page promotes wide applications on the Internet. However, to present web-oriented interactive multimedia raises extra requirements on network bandwidth, synchronization mechanisms, presentation engines, and authoring environments. Moreover, the heterogeneity of the Internet environment calls for open applications to fulfill these requirements seamlessly on various platforms. This paper proposes an approach to create Web-oriented synchronized multimedia documents by integrating the latest development in Java, Java Media Framework, JavaScript and HTML. As the result a WebSmart system is produced. It includes a presentation engine as well as an authoring environment, and it also realizes two levels of inter-object synchronization. Designed using an Object-Oriented methodology and implemented in Java, it aims to be a platform-neutral application. This paper introduces the system architecture and the technology framework of WebSmart system. Performance analysis and future work are also presented at the end of the paper.
