Abstract: The present invention relates to the synchronizing of equipment, and more precisely to the transporting of synchronization signals via a communication network with a view to inter-synchronizing the equipment. The invention concerns a reference station able to deliver packets in a packet switching network to communication devices connected to the network. According to the invention, the reference station comprises means for inserting at least a temporal offset in said packets, wherein said temporal offset describes data delivery duration on a pre-determined path of said network. The invention relates also to a sending communication device and to a receiving communication device.

Abstract: The invention concerns a method of transmitting, via a sending device, a data stream made up of data packets, at least some of these packets including time references for synchronizing the clocks of the sender and the receiver. The method includes at least a correction of the time references by the sender so as the receiver can offset the jitter introduced by the transmission. The invention is used to offset these losses of accuracy. The invention concerns also the device and corresponding receiver and reception method.
