Abstract
A microcomputer searches all the frequency bands included in each of the channel plans for TV and CATV almost continuously, determines whether or not there is a broadcasting station in the channel frequencies assigned to each of the channel plans, judges whether or not the channel frequency of a station that is judged to be present is within a fixed frequency range from the center frequency, and counts up the station present channel number for the channel plan to which the station belongs, if the station is within the fixed frequency range from the center frequency, for all the stations that are judged to be present. And a comparison is made between the counted TV channel number and the counted CATV channel number. If the TV count number is greater than the CATV count number, a TV mode is discriminated, while if the TV count number is smaller than the CATV count number, a CATV mode is discriminated.
