First, the terms used in the present invention are summarized as follows.

"Traffic broadcast" means a traffic-related information professional broadcast program configured to deliver information related to traffic information to audio information or audio and video information to viewers. "Broadcasting area information data" means coded information on a region currently being guided by traffic broadcasting (eg, Gangnam-gu, Seoul, Jongno-gu, Seoul, etc.). "Traffic information" means information provided as digitized data such as text, audio, video, and map image related to traffic transmitted through a wireless data network, and "traffic information" such as traffic congestion and traffic conditions in a specific area. It is a concept that encompasses "geographic information" about maps of specific areas and public offices, banks, restaurants, etc., that exist in specific areas.

 1 is a diagram illustrating a system for providing DMB traffic broadcasting program linked traffic information according to an exemplary embodiment of the present invention. The traffic information system includes a mobile DMB terminal 100, a traffic information providing server 200, and a DMB broadcasting station 300.

The DMB broadcasting station 300 multiplexes the broadcasting area information data 316 which is synchronized with the traffic broadcasting streaming data 312 and 314 and the streaming data, and comprises a code for a region which is currently guiding a traffic situation in the traffic broadcasting. The digital traffic broadcasting signal generated by multiplexing through 310 plays a role of transmitting.

The broadcasting area information data 316 is provided in the form of a data packet. When the area being broadcasted is Jongno-gu, Seoul, the broadcasting area information data 316 is configured to include a corresponding area code set by the service provider. . For example, if a broadcaster explains Jongno-gu, Seoul, and then guides traffic information for Gangnam-gu, Seoul, the broadcasting area information data 316 of the digital traffic broadcasting signal is synchronized to the corresponding video streaming data or audio streaming data so that the region of Jongno-gu, Seoul is synchronized. The code should be changed to the area code of Gangnam-gu, Seoul. DMB traffic broadcasting does not have to include video streaming data 312 and audio streaming data 314 as shown, and, when provided in the form of digital radio, may include only audio streaming data 314 as streaming data. have. DMB broadcast station 300 includes satellite DMB broadcast stations as well as terrestrial DMB broadcast stations as shown.

When the mobile DMB terminal 100 receives the digital traffic broadcasting signal transmitted from the DMB broadcasting station 300, detects the broadcasting area information data 316, and the viewer (the listener in the case of digital radio) requests detailed traffic information. It connects to the wireless data communication network 500 and performs a function of requesting traffic status information and geographic information for a broadcasting area. The mobile DMB terminal 100 basically includes a DMB broadcasting reception function and a wireless data communication network access function such as WAP, CDMA1x EV-DO, WLAN, and Portable Internet, and the viewer may request detailed traffic information. A traffic information menu 112 as shown in 2b is displayed on the display window. The mobile DMB terminal 100 recognizes the area currently being guided by traffic broadcasting through the detected broadcasting area information data 316. For example, when the traffic information is guided to Jongno-gu, even if there is no separate operation of the viewer, As shown in Figure 2b is configured to be able to request and receive detailed information on the traffic information of Jongno-gu immediately.

According to the configuration of the mobile DMB terminal 100, a viewer inputs a key (for example, an "execution" key) set in the mobile DMB terminal 100 when a traffic guide for a region of interest is transmitted through traffic broadcasting while driving. The detailed information on the destination can be obtained in a simple way so that the information required for the search can be compared to the method of navigating the hierarchical menu of the desired information while driving or searching by entering “Jongno-gu” directly. It offers the advantage of reducing time and distracting attention during operation.

Next, the traffic information providing server 200 includes a traffic situation information database 210 for storing traffic situation information and a geographic information database 220 for storing geographic information for each region to provide real-time traffic situation information for various regions and various destinations. Stores the geographic information, and transmits the traffic situation information and geographic information of the searched area to the viewer. Traffic status information can be provided from the Korea Highway Corporation Traffic Status Center, a private traffic information providing server, etc., which controls and manages traffic conditions in the city. The traffic information providing server 200 preferably further includes a map database 230 to further transmit a map image of a corresponding region, and the mobile DMB terminal 100 when the mobile DMB terminal 100 provides sufficient storage space. By directly storing the map database 230 in the time required to receive the traffic information can be shortened.

According to a preferred embodiment of the present invention, the mobile DMB terminal 100 further generates current location information, and when the viewer requests detailed traffic information, the viewer selects traffic status information and geographic information of the current location or broadcasting area. The traffic situation information and geographic information of the corresponding area may be requested, and the traffic information providing server 200 may transmit traffic state information and geographic information of the current location or broadcasting area. If the mobile DMB terminal includes a GPS receiver, the location information is generated by receiving accurate position coordinates from the GPS satellites, or the wireless data communication network uses the HLR (Home Location Resister) for the location information of the base station to which the terminal is connected, such as a CDMA communication network. If the registration is performed, the location information may be generated by receiving location information from the wireless data network service provider. According to this embodiment, the viewer can solve the problem of distraction during operation due to the operation of the telematics equipment because the detailed traffic information of the starting point (the current location) as well as the destination is also selected without complicated manipulation.

According to another embodiment of the present invention, the DMB broadcasting station 300 transmits a plurality of digital traffic broadcasting signals subdivided into regions, and the mobile DMB terminal 100 transmits digital traffic broadcasting signals of the region corresponding to the current location information. It is desirable to selectively receive. For example, if the traffic broadcasting area is divided into Gyeonggi, Gangwon, and Chungcheong to provide traffic information, most viewers generally move within their own area, so the traffic information for their destination is more likely to be broadcasted. It provides the effect of getting detailed traffic information about the destination.

According to another embodiment of the present invention, the mobile DMB terminal 100 receives a search term for geographic information search from a viewer and requests geographic information related to the search word, and the traffic information providing server 200 is illustrated in FIG. 2D. It is preferable to transmit the list of geographic information related to the search word to the mobile DMB terminal 100. For example, since the geographic information includes information on various destinations such as gas stations, restaurants, hospitals, schools, police boxes, public offices, cafes, etc., there is a problem that it is difficult to menu all the various destination information and provide it to the viewer. Therefore, it is more efficient to provide destination information, such as gas stations, hospitals, restaurants, etc., which are frequently requested to be searched by a menu method, and to input a search word for other destinations.

More preferably, in order to utilize the characteristics of the mobile DMB terminal in which communication and broadcasting are integrated, the traffic information providing server 200 stores the access phone number of the destination belonging to the geographic information in the geographic information, and stores the mobile DMB terminal ( 2F and 2G, when a viewer requests a telephone call to a destination belonging to geographic information, the call may be set to a corresponding access telephone number through a mobile communication network. According to this embodiment, the viewer calls a separate complicated procedure, for example, the telephone number guide service 114 to ask for the telephone number of the corresponding destination, or the desired destination even if the user does not search the phonebook stored in his mobile DMB terminal. This can provide the effect of setting up a call directly.
