Patent ID: 7262814

Claim:
Method of installing digital or analogue broadcasting channels of a frequency band, each channel being centred on a nominal frequency subject to drift or an offset at an effective frequency, in which each channel is successively installed by searching for it within a nominal capture span centred on the nominal frequency wherein: the channels are sought as a function of installing at least one previous channel, at least one maximum drift of the frequency band is calculated and when a channel is not found within its nominal capture span: this nominal capture span is offset as a function of the maximum drift, on either side of the nominal frequency of the channel, thereby obtaining a first and a second offset capture span, the effective frequency of the channel is found by successively searching the first and the second offset capture spans, the following channels are sought within their respective nominal capture span and, if capture is not successful, the nominal capture span of each of the following channels is offset in the direction of variation of the common drift estimated from the drift of the channel that was not found within its nominal capture span, as a function of the maximum drift and the following channels, are sought within their respective offset capture span.
