PROBLEM TO BE SOLVED: To eliminate the same channel interference by eliminating the same channel interference of a first input signal, outputting a second input signal, obtaining the error rates of the first and second input signals respectively for reference signals, generating driving signals by the error rate and selecting one from the first and second input signals corresponding to the driving signals. SOLUTION: A minimum SER detector 250 compares a first SER value B obtained in a first SER calculator 220 with a second SER value A obtained in a second SER calculator 240 and generates the driving signals C corresponding to a result. The driving signals C are signals for indicating the presence/ absence of NTSC signals and are provided with logic '1' in the case that the NTSC signals are present and the value of logic '0' in the other case. The driving signals are converted only when a first route or a second route for not continuously performing same channel interference elimination filtering during a second specified period and are provided with a previous value in the other case. |
