The antenna 110 receives a GPS signal from one or more satellites and transmits the GPS signal to the current position detector 170, and receives DMB data information including TPEG content information from the DMB data broadcast server 200 as an analog broadcast signal. Here, the TPEG content information may be configured in various ways such as travel information, traffic information, restaurant information.

The radio frequency transceiver 120 outputs an analog broadcast signal transmitted from the antenna 110 as an analog broadcast signal of an intermediate frequency. The baseband processor 130 converts the received analog broadcast signal into a DMB data stream by digitally demodulating the received analog broadcast signal of an intermediate frequency.

The decoder 140 analyzes the DMB data stream and uses the TPEG content information category as the audio / video decoder when the transport stream is audio / video broadcast data and the TPEG content information category when the TPEG content information is the TPEG decoder. To decode.

The area information database 150 classifies each area of the country and assigns a unique code to match the area code and area location information and store them in a table.

When the data setting unit 160 receives the content keyword selection signal indicating the desired content keyword information from the outside, the data setting unit 160 generates the content keyword information corresponding to the content keyword selection signal and transmits it to the controller 180.

The current position detector 170 receives the navigation data included in the GPS signal received from the antenna 110. In addition, the current position detector 170 generates latitude and longitude position information and time information of the vehicle from the received GPS signal. GPS signals transmitted from the main GPS satellites include identification codes, orbital positions, and visual information of the GPS satellites. The current position detector 170 calculates a difference in arrival speed between radio waves emitted from a plurality of GPS satellites. Calculate the position coordinates. The current position detection unit 170 may be mounted on the controller 180 to be described later without separately configuring.

The current location detection unit 170 receives GPS location information from the main GPS satellites, calculates current location information of the vehicle, and searches and gives an area code corresponding to the calculated current location information in the area information database 150.

When the controller 180 receives the content keyword selection signal indicating the content keyword information from the data setter 160, the controller 180 receives a region code corresponding to the current position of the vehicle from the current position detector 170. Subsequently, the controller 180 generates upload data combining the region code corresponding to the current location of the vehicle and the content keyword information to the DMB data broadcasting server 200 that manages the digital multimedia broadcasting through the radio frequency transceiver 120. send. The controller 180 receives the content information generated based on the area code of the current location of the vehicle and the content keyword information from the DMB data broadcasting server 200 and stores it in the memory unit 194.

The controller 180 compares the area code of the received content information with the area code of the current location of the vehicle, and displays the TPEG content information corresponding to the area code, through the output unit 192.

If the area code of the received content information does not match the area code of the current location of the vehicle, the controller 180 manually inputs the current location of the vehicle and performs the area code matching operation.

The modulator 190 modulates the upload data combining the region code and the content keyword information corresponding to the current location of the vehicle generated by the controller 180 and transmits the modulated upload data to the radio frequency transceiver 120.

The output unit 192 outputs the TPEG content information received from the DMB data broadcasting server 200 under the control of the controller 180. The memory unit 194 stores upload data combining the region code corresponding to the current location of the vehicle and the content keyword information and the TPEG content information received from the corresponding DMB data broadcasting server 200.

When the data setting unit 160 receives the content keyword selection signal indicating the content keyword information, the data setting unit 160 generates content keyword information corresponding to the content keyword selection signal and transmits the generated content keyword information to the controller 180.

The current location detection unit 170 receives the GPS location information, calculates the current location of the vehicle, and searches and gives area code information corresponding to the calculated current location of the vehicle in the area information database 150 (S102).

The controller 180 generates upload data combining content keyword information received from the data setting unit 160 and area code information corresponding to the current location of the vehicle calculated by the current location detection unit 170 (S104).

The controller 180 modulates the generated upload data through the modulator 190 and transmits the uploaded data to the DMB data broadcast server 200 through the radio frequency transceiver 120.

The controller 180 receives the TPEG content information retrieved from the DMB data broadcasting server 200 by using the content keyword information and the area code of the current location among the upload data (S106). Here, the TPEG content information includes area code information of the current location calculated in step S102.

For example, the bidirectional data transmitting and receiving apparatus 100 may automatically detect the current location of the vehicle when the user inputs only the 'restaurant name' and search for all restaurants having the 'restaurant name' corresponding to the location information. . Accordingly, the driver can search for various contents information of the driving area with a simple operation, thereby distracting the driver's attention and greatly reducing the risk of a traffic accident.

The current location detection unit 170 receives the GPS location information, calculates the current location of the vehicle, and searches and gives area code information corresponding to the calculated current location of the vehicle in the area information database 150 (S108).

The controller 180 determines whether the area code corresponding to the current location of the vehicle matches the area code of the received TPEG content information (S110).

If it is determined that the controller 180 matches the area code corresponding to the current location of the vehicle and the area code of the received TPEG content information, the controller 180 outputs the received TPEG content information corresponding to the matched area code through the output unit 192. It is displayed (S112).

If the controller 180 determines that the area code corresponding to the current location of the vehicle does not match the area code of the received TPEG content information, the controller 180 manually inputs or receives the location information through the user manual area setting process. A region code matching operation for manually matching a region code corresponding to the region code corresponding to the current position of the vehicle is performed (S114 and S116).
