Design of a Scalable Computer Cluster for MPEG-4 Parallel Encoder

This paper describes a architecture of homogeneous computer cluster for the parallel encoder of the natural video section of the MPEG-4 specification. The parallel encoder on this architecture can lower the negative impact on the achieved speed-up under high resolution input video data that has large communication overhead. Experimental results show that the proposed architecture is featured with scalability and has higher CPU utilization and speedup than general architecture of homogeneous computer cluster.
