The present invention relates to the domain of video equipment. It concerns more specifically a transmission device able to transmit packets, said device comprising the means to extract image ticks from a synchronisation signal, the means to initialise an image counter from said image ticks, the means to initialise a CPT_PCR counter every m passage through zero of the image counter, CPT_PCR producing counting ramps CSE_PCR with a range M, the means to sample the counting ramps CSE_PCR every Tech period, where Tech is from a time base synchronised on all the stations of said network, and the means to transmit packets comprising a PCRe sample of the CSE_PCR counting ramp. According to the invention, it also comprises the means to insert in the packet:—an Num index identifying the CSE_PCR counting ramp from which the PCRe sample is realised, and—a time label Datejnit indicating a CSE_PCR counting ramp timestamp passage through a reference value PCR_REF comprised between 0 and M-1. |
