Abstract
An IBOC broadcasting receiver that uses two different bit error rates as threshold values in receiving hybrid broadcasting in a simultaneous broadcasting format, and switches between digital broadcasting reception and analog broadcasting reception based on the two threshold values. The IBOC broadcasting receiver counts the number of occurrences of switching between digital broadcasting reception and analog broadcasting reception in a specified period of time, and increases a hysteresis width between the two threshold values when the number of occurrences of switching counted exceeds a specified number. Further, the counter of the IBOC broadcasting receiver counts the number of occurrences of switching of broadcasting receptions in a specified period of time by using another set of threshold values changed as a result of the increased hysteresis width, and reduces the hysteresis width between the another set of threshold values when the number of occurrences of switching counted is less than the specified number.
