A method for transferring information from an information provider (100) to an information consumer (190) in a highly efficient manner by means of a digital video broadcasting (DVB, 140) system and a secondary bidirectional transfer network (130). The secondary bidirectional transfer network provides information of where the DVB receiver (191) of the information consumer is located so that only suitable DVB transmitters (146) in the area are used for the information transfer itself. The location is determined by having at least one of either the transmitter frequency, the original network identification, the transport stream identification, and/or the network identification, of a transport stream of one transmitter that the receiver can receive transferred via the secondary bidirectional transfer network. Thereby only the necessary DVB transmitters need to be used for the information transfer, thus relieving the rest of the DVB transmitters (145, 147) from an unnecessary downloading. |
