Patent ID: 8514896

Claim:
Device able to receive packets circulating on a packet switching network, said device comprising: means to receive packets from said network, said packets comprising samples, said samples coming from a sampling of a first counting ramp having a range EX according to a sampling clock with a period T ech , said first counting ramp being timed by a clock with a period T_VID, said means to receive extracting said samples from said received packets, means to regenerate second counting ramps having the range EX, the means to regenerate receiving the samples and also delivering local samples of second counting ramps realised from a sampling clock and a reconstituted clock with the period T_VID, the second counting ramps being timed by the reconstituted clock, means to produce third counting ramps timed by the reconstituted clock and having a range EX_I where EX=m.EX_I, m being an integer greater than 1, the third counting ramps being set to zero at each passage of the second counting ramp by 0, means to produce a first signal consisting of first pulses at each passage of the third counting ramps by 0, wherein it also comprises means to produce a second signal, different from the first signal, consisting of second pulses synchronous with first pulses and wherein said second pulses are separated by a fixed number p of first pulses, where the number p is an integer greater than 1 and where the number m is an integer multiple of the number p.
