A system comprises a first server including a port, a memory, a processor operatively coupled to the port and memory, and a service application for execution by the processor. The service application is configured to: receive identification information related to an over-the-air radio broadcast via the port of the first server, wherein the identification information is transmitted to the first server using a radio broadcast receiver remote from the first server; communicate a request for automatic content recognition (ACR) of an Internet-based streaming version of the over-the-air radio broadcast; and receive metadata associated with the over-the-air radio broadcast in response to the request and initiate transmission of the metadata to the radio broadcast receiver.

An apparatus for transmitting shelter location information is disclosed. The apparatus for transmitting shelter location information according to an embodiment of the present disclosure includes a wake-up information checking unit that checks a value of a wake-up indicator provided in a head of a data file to determine whether a disaster has occurred; and a shelter location information insertion unit inserting the shelter location information into an advanced emergency alert table (AEAT), as it is confirmed by the wake-up information checking unit that a disaster has occurred.

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. A 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.
