Distributed Multimedia Content Processing Based on Web Service

A distributed computing application often uses multiple networked computers to work together to accomplish a complex task. So, it can be used to do calculation-intensive multimedia content computing too, such as video optical character recognition, shot detection and so on. Meanwhile, the Web is catalyzing a transition from PC-based software and file systems to Internet-based applications and Web services. We aim at the combination of multimedia computing and Web Services together that supports uniform naming, protection, and access for Multimedia Content objects stored by Web services to accomplish distributed computing. At a high level, it creates an integrated file and object system from heterogeneous, multimedia content objects dispersed across the Internet. Based on this fact, we proposed a novel framework of distributed multimedia computing in this paper. In this framework, the concept of workflow which can describe business processes logically is introduced. Some experiments show the effectiveness of the proposed framework.
