ABSTRACT:
In a broadband distribution system (SYS) for distributing television signals (TVS) and video signals (VOD), the return channel provided for requesting video signals is divided among the subscribers (TN) of the broadband distribution system (SYS) in such a way, that each group of subscribers (TN) is assigned a part of the return channel using time-division multiplexing, and the individual subscribers (TN) of a group have equal access to the part of the return channel assigned to the respective group. Access by the individual subscribers (TN) is monitored by a control unit (CONTROL) in the center (ZE) of the broadband distribution system (SYS). To synchronize the signals transmitted by the subscribers (TN) over the return channel using time-division multiplexing, the center (ZE) has a synchronizer (SYNC) which compensates for phase differences produced by differences in transit time.
