Patent ID: 8032074

Claim:
A method of setting a tuner connection state of n satellites, n being a natural number, the n satellites being connected to one or more antennas, the method being executed in a digital broadcast receiver comprising a plurality of tuners, the method comprising: setting the tuner connection state for each of the n satellites by using a satellite signal received from each of the n satellites; and setting the tuner connection state of the plurality of tuners between the n satellites by using a connection state set for each of the n satellites and the satellite signal received from each of the n satellites, wherein setting the tuner connection state for each of the n satellites comprises: determining whether each of a first tuner and a second tuner is tuned by tuning each of the first tuner and the second tuner to a first satellite signal received from a satellite of the n satellites; when each of the first tuner and the second tuner is tuned, extracting program specification information (PSI) or service information (SI) from the first satellite signal inputted through the first tuner and the second tuner, respectively, and determining whether the PSI or SI extracted from the first satellite signal inputted through the first tuner and the PSI or SI extracted from the first satellite signal inputted through the second tuner are identical to each other; tuning any one of the first tuner or the second tuner to a second satellite signal having polarization properties different from the first satellite signal when it is determined that the PSI or SI extracted from the first satellite signal inputted through the first tuner and the PSI or SI extracted from the first satellite signal inputted through the second tuner are identical to each other; and setting the tuner connection state of the satellite as dual same when the first tuner and the second tuner are tuned by the first satellite signal and the second satellite signal, respectively.
