AI Technical Summary

Technical Problem

In existing technologies, the management of vehicle radio broadcast databases relies on manual updates, resulting in missing information and low accuracy. This is especially true in countries or regions where RDS and DAB broadcasts are not supported, where administrators must listen to each broadcast to update the database, which is cumbersome and inefficient.

Method used

By using first and second tuners to receive broadcast audio signals, comparing the correlation of audio signals, automatically identifying and updating broadcast information in the radio broadcast database, and using radio streaming media sources to obtain missing information, automated database management is achieved.

Benefits of technology

It improves the accuracy and efficiency of the radio broadcast database, reduces administrator intervention, provides higher quality radio broadcast information, and simplifies the user experience for vehicle users.

Abstract

An apparatus for managing a radio broadcast database includes: a first broadcast setting unit configured to: set a frequency of a first broadcast using a first tuner; a second broadcast setting unit configured to: set, using a second tuner, a frequency of a second broadcast in which broadcast information exists; an audio signal comparison unit configured to: receive a first audio signal of the first broadcast and a second audio signal of the second broadcast, and check whether the first audio signal and the second audio signal are similar to each other; and a broadcast information providing unit configured to, if it is determined that the first audio signal and the second audio signal are similar to each other, acquire second broadcast information related to the second broadcast, and store the second broadcast information in the radio broadcast database as first broadcast information related to the first broadcast.
