The data encoder 64 compresses and codes the safe driving assistance data stored in the data server 62 based on a predetermined standard and sends the data to the multiplexer 72 in the form of a transmission frame. The data encoder 64 uses different standards according to the terrestrial DMB and the satellite DMB. In the case of the terrestrial DMB, the data encoder standard of Eureka-147 is used. In the case of the satellite DMB, the data carousel ( Data Carousel), etc. are used. That is, when the data encoder 64 is employed in the satellite DMB network, the safe driving assistance data is encoded to be transmitted by the data carousel, and the safe driving assistance data encoded in the MPEG-2 TS frame is loaded by 188 bytes. To Firearm 72. On the other hand, when the data encoder 64 is employed in the terrestrial DMB network, the safe driving assistance data is encoded in accordance with the multimedia object transfer (MOT) protocol or the TDC (transparent data channel) transmission and reception matching standard, and then X-PAD or packet mode. Is sent to the multiplexer 72.

The PSI / Service Information (SI) generator 66 generates / modifies / deletes PSI / SI information for an EPG service in real time based on the service information from the data server 62. Periodically sends the PSI / SI table to the multiplexer 72. The PSI / SI table in the PSI / SI generator 66 includes tables such as a program association table (PAT), a program map table (PMP), and the like. The PSI / SI table output from the PSI / SI generator 66 is loaded on the MPEG-2 TS (Transport Stream) and transmitted to the multiplexer 72.

The A / V encoder 70 receives an audio signal / video signal from the A / V source 68 and compresses and encodes the audio signal / video signal to the multiplexer 72. The data encoded by the A / V encoder 70 is loaded on the MPEG-2 TS (Transport Stream) and transmitted to the multiplexer 72.

The multiplexer 72 multiplexes the compressed coded data provided from the data encoder 64, the PSI / SI generator 66, and the A / V encoder 70 to the modulator 74. The data multiplexed by the multiplexer 72 is carried in the MPEG-2 TS (Transport Stream) and transmitted to the modulator 74.

When applied to the terrestrial DMB network, the modulator 74 modulates the input multiplexed information by the OFDM scheme, amplifies the multiplexed information to a size sufficient to communicate with the transmission tower, and sends the modulated information to the transmit antenna 76, and when applied to the satellite DMB network. Is modulated by the TDM / CDM scheme and amplified to a size sufficient to communicate with the satellite 30 to the transmit antenna 76.

The transmit antenna 76 transmits a signal input from the modulator 74, that is, a broadcast RF signal. The broadcast RF signal (that is, the DMB signal) transmitted from the transmission antenna 76 is transmitted to the terminal 40 via the transmission tower or satellite 30. The modulator 74 and the transmitting antenna 76 may be collectively referred to as transmitting means.

3 is an internal configuration diagram of the terminal of FIG. 1, which includes a DMB receiver 80, a data decoder 82, a broadcast content decoder 84, a DB 86, a platform 88, and a GPS receiving module 90.

The terminal of FIG. 3 assumes that the data encoder 64 of the transmitting device 20 receives and outputs the safety driving assistance data in a data carousel manner and processes the signal.

The DMB receiver 80 receives a broadcast RF signal (that is, a DMB signal) transmitted through the transmission tower or the satellite 30.

The data decoder 82 decodes the DMB signal received by the DMB receiving unit 80 and restores safe driving assistance data based on the data carousel method from the DMB signal.

The broadcast content decoder 84 constructs a DB 86 using safe driving assistance data in the form of a file restored by the data decoder 82. The information related to the safe driving stored in the DB 86 is composed of position information (ie, longitude / latitude coordinate information) for safe driving, road direction information, safe driving help code, speed limit, and the like. The information stored in the DB 86 is constantly updated. In addition, since the transmitting device 20 transmits broadcast multimedia information required by the terminal 40 in addition to the safe driving assistance data, the broadcast content decoder 84 broadcasts received other than the safe driving assistance data. The content is decoded and stored in the DB 86.

The platform 88 is an operating system (OS) for performing a function of the terminal 40, and the GPS receiving module 90 receives GPS information through a GPS antenna.

If present, the safe driving assistance data is sent to the voice synthesis service processor 94 together with the GPS information.

The voice synthesis service processor 94 synthesizes the input safety driving assistance data and outputs it to the outside through the speaker 96, but outputs a few meters in advance based on the GPS information. For example, the voice synthesis service processing unit 94 outputs a voice guidance message such as "80 km ahead of 100 meters".

Although not shown in FIG. 3, the terminal 40 displays a keypad for user input, a tuner for channel selection, a multimedia processor for displaying a broadcasting multimedia, and a video, a still picture, and a text.

In the content provider 10, the safe driving assistance data collected in real time is processed into a broadcast standard and transmitted to the transmission device 20 in the form of a file or a stream by wire or leased line.

Accordingly, the data server 62 of the delivery device 20 receives and stores safe driving assistance data from the content provider 10.

Then, the data encoder 64 of the transmitting device 20 compressively encodes the safe driving assistance data stored in the data server 62 based on a predetermined standard and outputs it in the form of a frame for transmission. At this time, the PSI / SI generator 66 of the transmitting device 20 generates / modifies / deletes PSI / SI information for EPG service in real time based on the service information from the data server 62 and periodically PSI. / SI Print the table. In addition, the A / V encoder 70 of the transmitting device 20 receives an audio signal / video signal from the A / V source 68 and compresses and outputs the audio / video signal.

Therefore, the multiplexer 72 of the transmitting device 20 multiplexes and outputs the compressed coded data provided from the data encoder 64, the PSI / SI generator 66, and the A / V encoder 70.

In the case of terrestrial DMB, the modulator 74 of the transmitting device 20 modulates the multiplexing information from the multiplexer 72 in a predetermined manner (e.g., OFDM, TDM / CDM) and transmits the data to a size that can be transmitted. Amplified and sent to the transmit antenna 76.

The transmitting antenna 76 transmits a broadcast RF signal (ie, a DMB signal) input from the modulator 74 to the terminal 40 through the transmission tower or satellite 30.

Accordingly, the DMB receiving unit 80 of the terminal 40 receives a signal from the transmitting antenna 76 (that is, a broadcast RF signal), and the terminal 40 performs safe tuning by performing channel tuning by EPG. Searching for channels with help data (using PAT and PMP tables), and when the channel with the safe driving help data is found, MPEG-2 TS is received from the channel.

Subsequently, the data decoder 82 of the terminal 40 decodes the received MPEG-2 TS according to a predetermined decoding technique and stores the received MPEG-2 TS in the DB 86 through the broadcast content decoder 84. The receiving end of the terminal 40 continuously receives the latest information related to the safe operation from the transmitting device 20 to update the DB 86.

Then, the safe driving warning service processing unit 92 in the terminal 40 continuously monitors whether the safe driving assistance data matching the GPS information from the GPS receiving module 90 is in the DB 86, and then the GPS information. If there is a safe driving assistance data matched with the corresponding GPS information and sends the safe driving assistance data to the voice synthesis service processor 94. Accordingly, the voice synthesis service processing unit 94 converts the corresponding safe driving assistance data into a corresponding voice, and outputs it through the speaker 96 several meters in advance based on the GPS information. For example, a voice guidance message such as "It is a section of 80 km in front of 100 meters" is output through the speaker 96. The voice guidance message is output in advance about 20 to 30 m before the point at which the 80 km section mentioned above starts. The 20-30m is a numerical value which can be adjusted as needed.

Accordingly, the driver listens to the voice guidance message output through the speaker 96 to drive safely.

Meanwhile, in the above description of the embodiments of the present invention, the voice guidance message is output for the safe driving of the driver, but the text guidance message may be displayed on the display means together with the voice guidance message.

As described in detail above, according to the present invention, the safe driving help data provided in real time from the content provider is broadcasted according to a predetermined standard and transmitted to the terminal in real time, so that the vehicle driver can receive a voice guidance message from the terminal. By doing this, you can drive more carefully and drive safely. Therefore, there is an effect to prevent the possibility of an accident in advance.
