000000180 520__ $$aWe address the problem of time-base synchronization for MPEG services in the presence of network jitter.  The conventional methods to obtain a stable clock indication are based on Phase Locked Loops (PLLs). They have the disadvantage of a long startup phase, therefore being unsuitable for services that require simultaneous accuracy and rapidity.  We develop a new time-base synchronization technique based on a Least-square Linear Regression algorithm (LLR). We show that LLR is able to perform time-base synchronization with the same accuracy of a PLL and with a substantial gain of rapidity.  Finally, we discuss the implementation of the LLR technique as an intermediate time-base synchronization level between the network and a generic multimedia application.
