A digital broadcasting receiving sensitivity alarming method is provided to make a user recognize receiving sensitivity and properly cope with drop of receiving sensitivity. A microcomputer extracts receiving sensitivity until the set first setting time passes(S120,S130). An average value of the extracted receiving sensitivity is counted(S140). A receiving sensitivity range in which the average value is included is checked(S150). It is determined whether the receiving sensitivity range to which a current average value belongs is lower than a receiving sensitivity range including a threshold value(S160). |
