Methods and apparatus for a play-out buffer that may adjust offsets between clocks of two ends of a network link with an adaptive play-out buffer and adaptive clock control. The play-out buffer is a circular jitter buffer that permits the absorption of a frequency offset using controlled slips between two nodes of a network. The play-out buffer also accommodates some wander introduced by the time-delay variation across the network. The adaptive clock control reduces the frequency offset between the clocks of the two nodes. In this manner, even though some offsets between two nodes would render communication inefficient, embodiments of the present invention allow the effects of these offsets to be mitigated, thus providing for a better quality coupling.
