The present invention relates to a device and a process for the stamping in real time by means of a stamping clock (2) of programs, as well as to a receiver and a broadcasting system containing such a device and a packet string obtained by such a process. The stamping device (40) comprises means of selection of one of the programs received, the so-called base program, a unit for activating locking (45) of the stamping clock (2) onto the encoding clock used for the base program and a system of time stamping (46), by means of the stamping clock, of all the packets of at least one of the programs received which is distinct from the base program. For at least some of the packets comprising encoding clock references, the so-called time utilized packets, the time stamps are equal to these clock references. For each of the other packets, the so-called current packet, the time stamp is obtained from the clock reference of the upstream time utilized packet closest to the current packet, and from a time increment given by the stamping clock between receptions of the upstream packet and of the current packet.
