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.
