摘要： Clock correlation can be achieved, for example, utilizing the RTP stream between a sender and receiver by determining a baseline at the start of, for example, a communication. This baseline is derived as a point in time from an arriving packet and represents a point from which subsequent packets deviate. Using this baseline, an early packet or a late packet can be detected. An early packet pushes the baseline down to that earlier point, while late arriving packets, if they are arriving late for a continuous period of time, represents a shift in the opposite direction from the baseline, resulting in a baseline moving to the “earliest” packet out of the sequence of the late arriving packets.
