In transmitting a packet string having variable packet intervals by converting the packet string into that having even packet intervals with each of the packets being attached with a time stamp as information for reproducing original packet string, when the value of the time stamp, which is decided by adding a specified offset time to the synchronization time, is not smaller than the value of the time stamp attached to the previous packet, the time stamp is attached to the packet and the packet is transmitted. If the value of the time stamp becomes not more than the value of the time stamp attached to the previous packet as a result of providing shortened offset time due to increased bit rate of the original packet string, the packet is discarded so as to protect the transmission from being stopped.
