Abstract:
The present invention relates to the domain of video equipment. In particular, the invention relates to a device able to receive packets in a network. The device comprises: means for receiving packets containing samples realised at a period, means for regenerating a ramp by means of a loop that delivers a clock, means for initialising, at every zero-crossing of the ramp, a counter whose rhythm is determined by the clock, means for generating image cues at every zero-crossing of the counter, and means for reconstituting a synchronisation signal from said image cues, means for transmitting the synchronisation signal to an item of remote equipment to be synchronised. According to the invention, the device comprises: means for receiving a return synchronisation signal identical to the synchronisation signal received by the equipment, means for extracting return image cues from the return synchronisation signal, means for transmitting, to the loop, a sum between a sample and a sample of a signal delivered by the image counter, the samples having been realised at a rate set by the return image cues.
