Patent ID: 7970369

Claim:
A method comprising: operating a receiving device in a network in which signals are broadcast at a plurality of different frequencies, the receiving device or a server including memory configured to store a plurality of sets of data, the data in each set identifying one or more frequencies at which a signal may be broadcast within the network; identifying at the receiving device a first frequency at which a signal with a signal quality exceeding a threshold is received; at the receiving device determining from the signal received at the first frequency a bundle identifier which identifies a bundle to which the received signal at the first frequency relates; identifying at the receiving device or the server two or more sets containing data identifying the first frequency, wherein each of the two or more sets also identifies a respective bundle carried on signals at the first frequency; using the received bundle identifier and the information in the sets of data to disambiguate between the identified two or more sets of data such as to provide a single candidate set of data; and extracting at the receiving device or the server other data from said single candidate set of data.
