The present invention relates to the domain of video equipment. More specifically, it concerns a reception device that comprises the means for: receiving packets containing samples, that come from data sampled every Tech period, where Tech is from a time base synchronized on all the stations of said network, regenerating a counting ramp having a count increment and a range value PCR_Modulus, using a phase-locked loop PLL1 that receives the samples and that delivers local samples every Tech period and a reconstituted clock, initializing, at every zero-crossing of the counting ramp, an image counter that is determined by the reconstituted clock. According to the invention, it comprises, further, means for determining the values of count increments.
