PROBLEM TO BE SOLVED: To actually measure signal intensity of each segment of a segment connection transmission signal of a terrestrial multimedia broadcast wave, and to easily grasp whether or not the level of each segment is lower than what is required at minimum due to influence of a multi-pass or the like.SOLUTION: Relative value calculation means 25 calculates a receiving level relative value which is a difference between a signal intensity characteristic value and a signal intensity characteristic reference value in each segment, and minimum receiving level relative value calculation means 28 calculates a minimum receiving level relative value of a minimum receiving level table 281 which is a difference between a minimum receiving level and a signal intensity characteristic reference value in each segment. A display control part 26 displays the receiving level relative value in each segment calculated by the relative value calculation means on a display unit 27 as a graph, and, when the receiving level relative value in each segment is lower than the minimum receiving level relative value calculated by the minimum receiving level relative value calculation means, distinguishably displays the segment. |
