3 is a flowchart of a traffic information display method according to a preferred embodiment of the present invention.

Referring to FIG. 3, a traffic information display method in a digital broadcasting terminal according to the present invention will be described in detail.

First, traffic information is received from the digital broadcasting center 100 (S300). That is, traffic information including at least one of text, still image, and moving image is received through the digital broadcast receiving module 200.

The traffic information can be received through various broadcasting channels or broadcasting services. For example, traffic information can be transmitted through various data broadcasting channels supported by Terrestrial Digital Multimedia Broadcasting (DMB). In addition, TPEG (Transport Protocol Experts Group), a protocol developed for the purpose of transmitting traffic and travel information through a digital broadcasting medium, and Traffic and Traveler (TTI), which can receive traffic conditions, weather information, Information service, and the like.

Then, the user inputs a specific place (S310). For example, the user may input a specific place through which the user wants to know the traffic information through the input unit 220. The specific location may be a map, such as a river, a mountain, or a major road such as a highway or a national highway, which is represented by a name such as a city / county / district, Including all the places that can be represented in.

Here, the input of the specific location may be input by a user through a key button, by displaying the map data stored in the memory unit 240, and then by touching a specific place through the touch screen.

The controller 230 transmits the received location information request message to the location information search server 130 through the mobile communication module 210 (S320).

The location information request message includes the specific location and the identifier of the user or the terminal.

The controller 230 receives the location information of the specific location searched by the location information search server 130 through the mobile communication module 210 from the location information search server 130 ].

The location information is preferably latitude and longitude information as described above, but is not limited thereto.

Here, as described above, when the specific location searched by the location information search server 130 is a plurality of locations, it is possible to receive all the location information of the searched plurality of specific locations.

Then, the controller 230 extracts traffic information for the specific place among the received traffic information using the received location information (S340).

Here, in the receiving step of the location information [S330], when the location information of a plurality of specific places is received, the traffic information of the specific place selected by the user is extracted from the plurality of specific places.

4 is a diagram showing an example of a user selection screen when a plurality of pieces of position information are received. For example, when the user transmits a location information request message to a specific location called "gullibon ", the location information search server 130 searches for a plurality of places including" gullibo " . As shown in FIG. 4, the user can select one of a plurality of specific places (for example, "Garibong station") received from the location information search server 130.

Then, the controller 230 displays the extracted traffic information on the display unit 250 (S350).

Here, the extracted traffic information may be displayed together with the map data of the specific place among the map data stored in the memory unit 240.

For example, FIG. 5 is an exemplary view showing traffic information composed of map data and text according to the present invention. That is, FIG. 5 shows an example of displaying together the map data about "around Gangnam Station" and the text traffic information about "around Gangnam Station".

FIG. 6 is a view illustrating traffic information including map data and image data according to the present invention. That is, Fig. 6 shows an example of displaying map data about "around Gangnam Station" and still image or moving image traffic information about "around Gangnam Station " together.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings.

According to the digital broadcasting terminal having the traffic information display function and the traffic information display method using the same according to the present invention, the user can obtain the location information of the specific place desired by the user using the location information search server interlocked with the mobile communication system The traffic information on the specific place can be actively acquired.
