<p>A method preserving an original timestamp value in a packet (70) of data to be transmitted from a transmission site to a reception site wherein the original timestamp value may require adjustment at the reception site to account for delays experienced by that packet (70) during multiplexing and/or transmission. The method comprises the steps of (a) defining at least first (88) and second (96) fields within the packet (70); (b) inserting, at the transmission site, an original timestamp value in the first field (88) of the packet (70), and thereafter not modifying the value in the first field (88); and (c) adding the value of any multiplexing or transmission delays experienced by that packet (70) to an initial value in the second field (96). At the reception site, the second field (96) will reflect any delays experienced by the packet (70) while the original timestamp value is preserved in the first field (88).</p> |
