FIELD: digital relay systems, in particular, digital television.
SUBSTANCE: central relay station, which is a portion of digital relay system, is assigned with a function of assigning to decoders, also included in system, of values of access control level, which allows dynamic assignment of such values and better control of quantity and format of addresses, with which current system usually operates. Also, central relay station can relay data by broadcasting in several transport packets streams, or in several services in each one, while message concerning address assignment additionally has data, allowing each decoder to pick a stream from multiple streams, which contains data, associated with current address of access control level.
