Abstract
Techniques to adjust clock approximations are described, which may be used to synchronize content output at a client. In an implementation, timestamps derived from a universal time source are allocated to respective program clock reference (PCR) timestamps in content received by a network operator during an interval of time to form ordered pairs of timestamps. An approximation is computed of a plurality of the ordered pairs of timestamps for the interval and the approximation is adjusted using an ordered pair of timestamps taken from a previous approximation.
