A feedback approach for jitter and skew enforcement in multimedia retrieval services

End-to-end delay jitter has a great impact on the continuity of playback of information. A system supporting multimedia services has to be equipped with functions which will guarantee intra/intermedia synchronization requirements by limiting variations in the delay jitter. In this paper an end-to-end mechanism to meet the intra/intermedia synchronization requirements of a distributed multimedia retrieval service is introduced. The mechanism is based on a prediction of the network delay jitter suffered by each information unit at the destination site and retrieval time modification at the source site in such a way to reshape the delay jitter and skew probability density functions
