Method for transmitting packets in a transmission system

Method for transmitting packets wherein first packets are encapsulated in second packets in a transmission system in which part of the first packets contain a first timing reference for synchronization of a receiver clock and at least part of said second packets contain a second timing reference for reducing transmission jitter of the second packets at the receiver, said first timing reference generated by means of a first clock, and said second timing reference being generated by means of a second clock, the method comprising the steps, at a transmitter, of:

• collecting first packets;
• determining whether a collected first packet contains a first timing reference;
• and
• immediately triggering transmission of a second packet encapsulating collected first packets including said first packet containing the first timing reference upon determination that said collected first packet contains said first timing reference, said second timing reference of said second packet being set, upon said transmission, to a current value of said second clock, said second timing reference corresponding to a transmission time of said first packet containing the first timing reference.
