Abstract
A broadcast wave synchronization signal converting device that synchronizes broadcast waves with GNSS signals on a reception side and corrects the broadcast waves to global standard times by use of correction values, thereby performing periodic calibrations of frequencies. The broadcast wave synchronization signal converting device includes: a PLL circuit reproduces system clocks on the basis of time information acquired from received broadcast waves; a subtractor (C1) subtracts, from a counter value corresponding to the periodic signal intervals of GNSS signals, a counter value of the system clocks counted at the signal intervals and outputs the difference value; a control amount adjustor calculates a control amount of synchronization as a correction value on the basis of the difference value; and a subtractor (B) subtracts the correction value from the acquired time information and sets the corrected time information to a PCR counter as the internal time information thereof.
