The present invention relates to a vehicle multimedia apparatus, and more particularly, to an audio video navigation (AVN) system.

In general, an audio device installed in a vehicle receives a radio broadcast signal and outputs an audio signal based on the radio broadcast signal to the speaker. In order to select a desired radio broadcast channel, the user changes the reception frequency band of the tuner unit by using the frequency adjustment button.

Meanwhile, the user may preset a plurality of radio broadcast channels which are frequently listened to in shortcut keys (ie, preset keys). As a result, the user can listen to the preset radio broadcast by simply inputting the corresponding shortcut key.

In general, however, in order to use the preset function of a radio station, the user must search for the radio station one by one using the frequency control button, and then register the searched station with the preset key by operating a function key. do.

As described above, the conventional audio device is very troublesome because the user needs to directly manipulate the conventional audio device by hand in order to select a desired radio broadcasting channel. In addition, since the user cannot concentrate on driving due to the operation of the audio device for selecting a radio broadcast channel, it is difficult to ensure safe driving.

Accordingly, the technical problem to be achieved by the present invention is to provide a user with convenience by recognizing the user's voice and changing the reception frequency band of the tuner so that the radio broadcast channel corresponding to the name of the broadcasting station is selected according to the recognition result. The present invention provides an AVN system having a radio broadcast channel selection function based on voice recognition.

In response to the position request signal, the navigation device calculates a current position based on position data received from Global Positioning System (GPS) satellites, and outputs position information based on the current position.

The microphone converts the user's voice into an input audio signal and outputs it. The audio processor converts an input audio signal received from the microphone into input audio data in response to the first mode control signal, and outputs the converted audio signal. The audio device outputs a first mode control signal to the audio processing unit and outputs a location request signal to the navigation device in the radio reception mode, and outputs radio frequency information stored in advance corresponding to the region based on the location information received from the navigation device. Check it.

The audio device recognizes the user's voice based on the input audio data received from the audio processor, selects one of the plurality of radio frequency signals based on the recognition result and radio frequency information stored in advance corresponding to the region. It receives and outputs broadcast audio data to an audio processing unit based on the received radio frequency signal. The audio processor converts the broadcast audio data received from the audio device into a broadcast audio signal and outputs the broadcast audio signal to the speaker.

As described above, the AVN system according to the present invention recognizes the user's voice and changes the reception frequency band of the tuner unit so that the radio broadcast channel corresponding to the corresponding broadcasting station name is selected according to the recognition result, thereby providing convenience to the user. can do.

The audio controller 144 broadcasts the radio frequency information corresponding to the name of the corresponding broadcasting station in the region based on the information BSTM and the location information POIF selected by the user, in the storage 142. Search in the list table (LTBL). For example, when the current location according to the location information POIF is the Seoul area, and the corresponding broadcasting station selected by the user is "MBC FM4U", the radio frequency information retrieved by the audio control unit 144 is "FM 91.9 MHz". . The audio controller 144 outputs a broadcast selection signal BSEL including radio frequency information retrieved from the broadcast list table LTBL to the tuner 145.

Meanwhile, according to the current position, the plurality of radio frequency information may be searched by the audio controller 144 in the broadcast list table LTBL. In this case, the audio controller 144 outputs the video data VDAT5 including the list of the retrieved plurality of radio frequency information to the display apparatus 150. The display apparatus 150 displays a list of retrieved plurality of radio frequency information, as shown in FIG. 3, based on the video data VDAT5.

When the user checks the list of the plurality of radio frequency information displayed on the display device 150 and selects the desired radio frequency information by operating the input keys 141, the input unit 141 may input key input signals IPKEY1. IPKEYJ) is output to the audio control unit 144. The audio controller 144 selects one of a plurality of radio frequency information in response to the key input signals IPKEY1 to IPKEYJ, and tunes the tuner 145 to a broadcast selection signal BSEL including the selected radio frequency information. Output to

The tuner 145 selects and receives a radio frequency signal (one of FREQ1 to FREQM) corresponding to the radio frequency information included in the broadcast selection signal BSEL in response to the broadcast selection signal BSEL. The tuner 145 outputs the broadcast audio data BADAT to the audio control unit 144 based on the received radio frequency signal (one of FREQ1 to FREQM).

The audio controller 144 outputs broadcast audio data BADAT to the audio processor 130. The audio processor 130 converts the broadcast audio data BADAT into a broadcast audio signal BDAUD and outputs the same to the speaker 160. As a result, the user can select the desired radio broadcast simply by saying the name of the corresponding broadcast station without directly manipulating the audio device 140 to listen to the desired radio broadcast.
