FIELD: communications engineering.
SUBSTANCE: in accordance to the invention, ground-based digital video-broadcasting network contains content provider and three transmitters. Integrated receiver/decoder (IRD) moves in a zone near transmitters. By transmitting service information as a part of network information table at data level, transmitters provide transmission parameter information in their output signals as data for signaling transmission parameters (TPS) at physical level. Aforementioned TPS information includes one bit, which defines to which type of network the signal is related, and information, which denotes whether the signal contains data flows, quantized in time. That information is used by (IRD) both in scanning a signal or (IRD) initialization by parameters, required for detection of service at 1-2 levels of open systems (OSI), and for canceling selection of signals as candidates for relay service transfer. Because transmission parameter information is transmitted more often and at lower OSI level compared to network information table, (IRD) may efficiently make decisions: whether the signal is fitting for relay service transfer, or whether it is a signal of interest.
EFFECT: reduction of energy consumption in mobile receiver.
