Multimedia synchronization and UNIX [chapter]

Dick C. A. Bulterman, Robert Liere
1992 Lecture Notes in Computer Science  
Even if jitter, for example, could be eliminated from the network entirely, the scheduling of operating system tasks could easily reintroduce variations in the latency to the user.  ...  Thus, the designer of distributed multimedia systems must face the problem of real-time scheduling in the operating system from device driver handling up to presentation layer processing.  ...  The basis of our approach is to integrate a distributed operating system kernel as a multimedia co-processor.  ...
