Abstract:
A receiver for receiving packets of telephony and data signals on a network from multiple transmitters, wherein each transmitter comprises adjustment means for adjusting the start time of transmission of packets, said receiver comprising:means for communicating from the receiver to each transmitter,means for generating a synchronizing pattern and communicating said synchronizing pattern to each transmitter,means for measuring a packet arrival time of each packet from each transmitter, said packet arrival times being measured relative to the communication of said synchronizing pattern to each transmitter,means for identifying a latest packet arrival time which is at least as large as any other packet arrival time,means for determining a delay factor for each transmitter, each of said transmitter delay factors being dependent upon the packet arrival time from the corresponding transmitter,wherein each transmitter is characterized as having a location on said network,and whereineach transmitter delay factor is determined by the difference between the packet arrival time from the corresponding transmitter and said latest packet arrival time,each adjustment means is dependent upon a second communication from said receiver,each of said second communications to each transmitter is dependent upon the corresponding transmitter delay factor, andeach adjustment means at each transmitter is such that packet arrival time of subsequent packets at the receiver is independent of the location of the transmitter of said subsequent packets.
