Abstract: The invention relates to the field of the synchronization of data delivery onto equipments connected over a packet switching network, in particular when the equipments are devoted to video and audio data or Auxiliary data linked to processing and are connected over a local area network for forming a video/audio production studio. More precisely the invention concerns a data inserter device for inserting a timestamp in packets, and a delay compensating device for extracting said timestamp and compensating the delivery delay and in particular the jitter, the network delay and the packet generation duration or any additional user delay.

Abstract: The present invention relates to the synchronizing of equipment, and more precisely to the transporting of synchronization signals via a communication network with a view to inter-synchronizing the equipment. The invention concerns a reference station able to deliver packets in a packet switching network to communication devices connected to the network. According to the invention, the reference station comprises means for inserting at least a temporal offset in said packets, wherein said temporal offset describes data delivery duration on a pre-determined path of said network. The invention relates also to a sending communication device and to a receiving communication device.

Abstract: The invention relates to a device for temporal slaving in a packet data transmission network, each data packet comprising a time label, comprising means of temporary storage. According to the invention, the said device is such that:—the means of temporary storage have a storage capacity able to record data received for a predetermined time (IPDV) dependant on the characteristics of the network, the said device furthermore comprising—means for regenerating a local reception clock as a function of the time label of the incoming packets,—means for reading the data in the buffer memory at an instant dependent on the said predetermined time (IPDV) and on the regenerated local clock.
