Claim:
1. A method for estimating a time of transmission of data packets transmitted between a transmit terminal (TE) and a receive terminal (TR) via a transmission channel (C D ), the time of transmission of data corresponding to the time at which the data is transmitted from the transmit terminal (TE), the data propagating from the transmit terminal to the receive terminal with an unknown propagation delay, comprising the steps: (a) in said transmit terminal, generating at least one synchronization signal (S (b) transmitting said data on said transmission channel from the transmit terminal to the receive terminal; (c) transmitting said synchronization signal on an auxiliary transmission channel (C (d) in said receive terminal, receiving each data packet to be synchronized and the synchronization signal; (e) synchronizing each data packet received by said receive terminal by means of said synchronization signal; and (f) estimating the time of transmission of the data using the known propagation delay of the synchronization signal and the temporal relationship of the synchronization signal with the time of the transmission.
