Satellite receiving channel data 810 are described in a network
information table (NIT) in a random fashion. Frequencies in the
redelivering facility in a community receiving system are arranged in
order of increasing frequencies for each of the networks. In a receiver
unit, the frequencies 753 of the satellite receiving channel data 810 are
rearranged in order of increasing frequencies and are registered to the
receiving frequencies 831 in a frequency conversion table 830. The
receiver unit selects the frequency according to wire frequencies 822 of
a wire channel 821 in a wire frequency table 820 and registers the wire
frequency of a channel that can be normally received to a conversion
frequency 832 in the frequency conversion table 830. Therefore, the
frequency data contained in the broadcast signals before being
redelivered are corresponded to the redelivering frequency of signals
really transmitted through a cable on the receiver unit side in the
community receiving system.
