Abstract
A receiving unit receiving packets of a packet stream having an evaluating unit for comparing the arrival times of the packets to a generated clock signal. The generated clock signal is used in transmitting information carried in the packets from the receiving unit. From the delays, a signal producing unit determines a characteristic delay value, which is characteristic of or typical of the statistical distribution of the delays. This characteristic delay value may be an average of the smallest delays of the distribution of delays for the latest received packets, and is used for adjusting the frequency of the generated clock signal. The average may be calculated or derived from all of the smallest delays of the distribution obtained for a predetermined share of the latest received packets.
