Patent ID: 8737411

Claim:
A reference station configured to deliver packets in a packet switching network having a non-constant transmission time to communication devices connected to the network, said reference station comprising: means for retrieving image ticks from a sync signal received by said reference station; means for initializing an image counter from said image ticks; means for initializing a counter at each m th reset of the image counter, the counter being cadenced by a clock produced by the image counter, m being a positive, non-zero integer; means for sampling the counter at each T ech period, T ech being issued by a time base synchronized on all stations of the network, means for delivering packets comprising samples of the counter; and, means for inserting at least a temporal offset in said packets, wherein said temporal offset describes a data delivery duration on a pre-determined path of said network in order to address the non-constant transmission time of said packets.
