Abstract

With the advent of digital TV and interactive multimedia over broadband networks, the need for high performance computing for broadcasting is stronger than ever. Processing a digital video sequence requires considerable computing. One of the ways to cope with the demands of video processing in real-time, we believe, is parallel processing. Scheduling plays an important role in parallel processing especially for video processing applications which are usually bounded by the data bandwidth of the transmission medium. Although periodic real-time scheduling algorithms have been under research for more than a decade, scheduling for continuous data streams and impact of scheduling on communication performance are still unexplored. In this paper we examine periodic real-time scheduling assuming that the application is communication constrained where input and output data sizes are not equal.
