SOPA - a self organizing processing and streaming architecture

Abstract

This paper describes SOPA, a component framework that is an essential part of the lecture recording system E-Chalk. It envisiones a general processing and streaming architecture featuring autonomous assembly of stream processing components. The goal is to provide an easy to use framework where dynamically organized processing graphs are build out of components from various distributed sources. Based on state-of-the-art solutions for component based software development the system simplifies the implementation and the configuration of multimedia streaming applications and associated tools. It supports stream synchronization transparently while extending components are installed on the fly according to the existing requirements that may change at any time.
