Abstract: Method and system for broadcasting digital services comprising a plurality of receiver sets located in several regions and at least one broadcasting facility which rebroadcasts several services with region-specific contents in a single transport stream (TS) consisting of time multiplexed digital packets, said TS reaching all the receiving sets in all the regions in the area covered by the signals originating from said broadcasting facility, the region-specific content being extracted from said TS by the receiving sets of each targeted region by filtering the packets containing region-specific and service-specific packet identifiers—PID's—which are periodically changed as a function of time in accordance with information contained in private tables which are also included in said TS.
