Abstract

This paper describes a PC-cluster system for real-time distributed video image processing. The PC-cluster consists of eight PCs connected by a very high speed network. The key issue of this system is synchronization of distributed video data. Frame synchronization module is introduced to realize three kinds of synchronization: forward synchronization, barrier synchronization and backward synchronization. Forward synchronization is to notify of timing to start processing. Barrier synchronization is to wait for all data that are processed at the same time. Backward synchronization is to cancel processing and transferring useless data. Experimental results are also shown to confirm the performance of the PC-cluster.
