<p>A network includes a service provider, a plurality of transmitters and a receiving device. The receiving device identifies the frequencies at which broadcast services are provided by a transmitter local to the receiving device. A search is carried out until a signal is received by the receiving device (S4.1). Then, the receiving device looks-up the transmitter (step S4.2). This involves searching the table 29 and identifying the row 30 that includes data corresponding to the frequency of the found signal. Optionally, it is determined whether or not there is only one candidate transmitter (step S4.3), by determining how many rows 30 in the table 29 include data corresponding to the frequency of the found signal. If there is more than one row, then the transmitter is disambiguated (step S4.4.).</p> |
