With the recent increase in self-driving drivers, Telematics combines location-based services (LBS) with vehicles to provide drivers with real-time information on vehicle accidents and theft detection, driving directions, traffic and living information, and games. Services are emerging. Among various telematics services, there is a navigation service that provides a vehicle with a moving path from a current location to a destination by inputting information on a current location and location information on a destination.

Conventional navigation service is provided through a mobile communication terminal equipped with a server or navigation software that provides a navigation service when the mobile subscriber enters information about the current location and destination. Conventional navigation service calculates information on the movement route of the destination from the current position, and provides the driver with the information on the calculated movement route.

However, when a vehicle accident occurs or a sudden road congestion or a construction section occurs, information about a moving path according to a changed situation may not be provided in real time. In addition, it provides only the route guidance function and cannot provide various information about the surrounding area (eg, restaurants, tourist attractions, etc.).

Meanwhile, D.M.B (DMB), which is a new concept of mobile multimedia broadcasting service combining broadcasting and communication, has attracted attention. DMB is a broadcasting service that digitally modulates various multimedia signals such as voice and video and provides them to portable and in-vehicle receivers. DMB is based on Digital Radio Broadcasting (DAB), a digital radio technology. In addition, the multimedia broadcasting concept has been added to send various data such as video, weather, news, stocks and traffic information. It is a service that can. In particular, CD, DVD-class high-quality sound and high-definition broadcasting can be enjoyed on the go, attracting attention as the next generation broadcast.

In particular, as a DMB data service, a next generation navigation service using a Transport Protocl Expert Group (TFT) technology for transmitting real-time traffic and travel information along with a DMB broadcast signal has been developed. T.P.G. is an international standard protocol for the transmission of traffic and traveler information via digital media. Among the DMB data, the T.P.E data can only know the traffic and traveler information at the time of transmission, and thus, the T.P.E.Data data can not use the previously received traffic and travel information.

An object of the present invention is to provide a method for storing point of interest information of T.P.E. data of a digital broadcast receiving terminal.

Another object of the present invention is to provide a method for displaying point-of-interest information of T.E. data of a digital broadcast receiving terminal.

Table 1 is a table for managing a plurality of points of interest information stored in the point of interest information storage area 113. At this time, the table includes an identification number 21 field, an effective time 23 field, a classification item 25 field, a description item 27 field, a guide coordinate 29 field, and the like. The valid time 23 field indicates a time at which the point of interest information is valid, that is, a date and time when the point of interest information is deleted. The description item 27 field includes a textual description (eg, address, menu, article, phone number, web address, description, information, name, title, timetable, reservation information, map, map, etc.) and related photo information. The guided coordinate field 29 is the coordinate for access (eg parking lot, entrance, etc.).

For example, the identification number 21 '0x02' is the effective time 23 is '07 / 01/12 ', the classification item 25 is' destination', and the description item 27 is' Seoraksan ', The guide coordinate 29 is point of interest information of '37 degrees latitude, 128 degrees longitude '. At this time, the plurality of points of interest information is divided by the identification number (21).

The digital broadcast receiver 120 receives a digital broadcast signal. The digital broadcast receiver 120 converts the received digital broadcast signal into a baseband digital signal. In particular, the digital broadcast receiver 120 according to the present invention divides the digital broadcast signal into an audio signal, a video signal, and a data signal. Subsequently, the digital broadcast receiver 120 outputs an audio signal to the audio processor 170, decodes an image signal into an MPEG standard signal, and outputs the audio signal to the display unit 150. The digital broadcast receiver 120 extracts the traffic and travel information from the data signal and outputs it to the controller 140.

The satellite signal receiver 130 receives satellite signals. The satellite signal receiver 130 converts the received satellite signal into a baseband digital signal.

The controller 140 controls the overall state and operation of the digital broadcast receiving terminal 100. In particular, the controller 140 according to the present invention includes an extraction module 141, a determination module 143, a search module 145, a position calculation module 147, and a navigation processing module 149.

The extraction module 141 extracts the point of interest information of the T.P.E. data. Specifically, the extraction module 141 is interested by the T. E. identification number of the plurality of information (e.g., road traffic message, public transportation information, point of interest information, etc.) of the T. easy data. Extract branch information separately. Subsequently, the extraction module 141 transmits the extracted point of interest information to the determination module 143.

The determination module 143 determines whether the point of interest information received from the extraction module 141 is included in a pre-stored category. When the determination result is included in the stored classification item, the determination module 143 determines whether the received point of interest information is the same as the previously stored point of interest information. If the determination result is different from the stored point of interest information, the determination module 143 stores the received point of interest information in the storage unit 110. On the other hand, if the determination result is the same as the stored point of interest information, the determination module 143 does not store the received point of interest information.

On the other hand, if the determination result is not included in the pre-stored category, the received point of interest information is not stored.

If the preset POI display mode is the search mode, the search module 147 searches for POI information corresponding to the input search word according to the user's selection information and notifies the search result to the controller 140.

The position calculation module 147 calculates the current position coordinates from the satellite signal received from the satellite signal receiver 130. In particular, the position calculation module 145 calculates the movement distance and the movement time from the current position coordinates to the guide coordinates of the stored point of interest information. At this time, since the method for calculating the abnormal distance and the moving time is outside the gist of the present application, a detailed description thereof will be omitted.

The navigation processing module 149 displays the guide coordinates of the point of interest information stored in the point of interest information storage area 113 at the corresponding coordinates of the stored map image. Subsequently, when specific point of interest information is selected from the displayed point of interest information, the navigation processing module 149 performs a path guidance to guide coordinates of the selected point of interest information. In this case, the navigation processing module 149 controls the display unit 150 or the audio processing ratio 170 to perform the path guidance to the guide coordinates of the selected point of interest information.

When the delete command is input to specific point of interest information among the displayed point of interest information in the point of interest information display mode, the controller 140 stores the identification number of the point of interest information in the deletion information storage area 115. And delete the point of interest information. If the point of interest information of the next received T.P.G. data is the same as the identification number stored in the deletion information storage area 115, the controller 140 does not store the extracted point of interest information.

When the point of interest information display mode change request signal is input, the controller 140 sets the point of interest information display mode to the selected specific point of interest information display mode.

The display unit 150 displays the state and operation process of the digital broadcast receiving terminal 100. In particular, the display unit 150 according to the present invention is preferably a touch screen for recognizing a user's touch. For example, the display unit 150 selects specific point of interest information by a user's touch operation among a plurality of point of interest information displayed under the control of the controller 140.

In addition, the display unit 150 displays the point of interest information stored in the point of interest information storage area 113 under the control of the controller 140 according to the set point of interest information display mode. Here, the point of interest information display mode may be any one of a date-specific display mode, a peripheral display mode, and a search mode. In addition, the display unit 150 displays the path from the current position coordinate to the guide coordinate of the specific point of interest information on the map image under the control of the navigation processing module 149.

1 and 2, when the digital broadcast reception terminal 100 operates in the digital broadcast reception mode (S110), the controller 140 receives a digital broadcast signal from the digital broadcast receiver 120 (S120). At this time, the digital broadcast receiver 120 separates the received digital broadcast signal into an audio signal, an image signal, and a data signal. In particular, the digital broadcast receiver 120 extracts the T.P.Eg data from the data signal and transmits it to the controller 140.

Next, the controller 140 controls the extraction module 141 to extract the point of interest information from the received T.P.E. data (S130). The controller 140 classifies and extracts the point of interest information based on the T.P.E.ID number among a plurality of data (eg, road traffic message, public transportation information, etc.) included in the T.P.T.T data. do. The controller 140 reads the identification number and the classification item from the point of interest information (S140) and determines whether it is the same as the classification item stored in the storage unit 110 (S150). If the determination result is the same, the controller 140 determines whether the identification number stored in the point of interest information storage area 111 and the identification number read in step S140 are the same (S160). If the determination result is different, the controller 140 stores the point of interest information corresponding to the read identification number in the point of interest information storage area 110 (S170). If the determination result is the same, the controller 140 deletes the extracted ROI information (S180).

On the other hand, if it is determined that the above-described process S150 is different, the controller 140 deletes the extracted point of interest information (S180).

An example of a first screen to be displayed, and FIG. 10 is an example of a second screen to display the retrieved point of interest information of FIG. 6.

1, 3 to 9, when the operation mode of the digital broadcasting reception terminal 100 is the point of interest display mode, the controller 140 receives a satellite signal from the satellite signal receiver 130 (S210). Subsequently, the controller 140 calculates a current position coordinate from the received satellite signal (S215).

The controller 140 checks the set point of interest information display mode (S220). As a result of the check, if the set point of interest information display mode is a display mode for each date, the controller 140 sorts the point of interest information in order of the latest date and displays the point of interest information in the form of a list on the display unit 150 (S230). By sorting and displaying the latest date, the user can know the recently received point of interest information. See FIG. 4 for a detailed description of the process of displaying the point of interest information sorted by date.

Referring to FIG. 4, the controller 140 displays the point-of-interest information stored in the point-of-interest information storage area 113 on the display unit 150 in the order of the latest date (S231). For example, as illustrated at 230, points of interest information is displayed in a list. Next, the controller 140 determines whether a selection signal is input to specific point of interest information among the displayed point of interest information (S232). As a result of the determination, when there is an input of the selection signal, the controller 140 controls the position calculation module 147 to compare the guide coordinate of the selected point of interest information with the current position coordinate calculated in step S215 of FIG. The time is calculated (S234). Then, the controller 140 displays the selected point of interest information, the moving distance, and the moving time. For example, the controller 140 controls the navigation processing module 149 to display point-of-interest information, moving distance, and moving time in corresponding coordinates on a map.

Next, the controller 140 determines whether the route guidance request signal is input (S235). As a result of the determination, if there is an input of the route guidance request signal, the controller 140 controls the navigation processing module 149 to perform route guidance from the current position coordinate to the guide coordinate of the selected point of interest information (S236). In this case, the navigation processing module 149 may display a path by embodying a map image displayed on the display unit 150. For example, if point-of-interest information of '1.AAA Jongno' 231 of FIG. 7 is selected, the interest of '1.AAA Jongno' 231 is shown, as shown at 235 of FIG. 7. Perform route guidance to the branch information. In addition, the navigation processing module 149 may of course output the route guidance as an audio signal through the audio processing unit 170.

Referring back to FIG. 3, if the set point of interest information display mode is the surrounding display mode, the controller 140 displays the surrounding point of interest information through the display unit 150 (S240). See FIG. 5 for a detailed description of the process of displaying the surrounding point of interest information.

Referring to FIG. 5, the controller 140 controls the position calculation module 147 to compare the guide coordinates of the stored point information of interest with the current position coordinates (S241). The guide coordinates of the point of interest information included in the set range exist. It is determined whether (S242). At this time, the set range is a range that can be displayed on the screen during navigation, when the digital broadcast receiving terminal is manufactured. For example, the set range is preferably a 10km radius around the current position coordinates. If the determination result exists, the controller 140 controls the position calculation module 147 to calculate the movement distance / travel time from the current position coordinate to the guide coordinate of the point of interest information existing in the set range (S243).

The controller 140 controls the navigation processing module 149 to display the current coordinates of the location and the guide coordinates of the point of interest information existing in the set range on the map. In addition, the controller 140 controls the navigation processing module 149 to display the moving distance / travel time in the neighborhood of the guide coordinate of the corresponding point of interest information on the map image, or the corresponding point of interest in a predetermined region of the display unit 150. It is preferable to display the moving distance / travel time of the information in the form of a list. In this case, the predetermined area is preferably the left area of the display unit 150. For example, as shown by reference numeral 240 of FIG. 8, guide coordinates of the point of interest information existing in the range set in the map image are displayed.

Subsequently, the controller 140 determines whether a selection signal is input to specific point of interest information among the displayed point of interest information (S245). If the selection signal is input to the point of interest information, the controller 140 controls the navigation processing module 149 to perform a path guidance from the current position coordinate to the guide coordinate of the selected point of interest information (S246). For example, as illustrated by reference numeral 245 of FIG. 8, route guidance is performed to guide coordinates 241 of selected point of interest information among guide coordinates of point of interest information shown in 240.

Referring back to FIG. 3, when the above-described S220 process check result indicates that the set point of interest information display mode is a search mode, the controller 140 searches for the point of interest information and displays the found point of interest information through the display unit 150. (S250). See FIG. 6 for a detailed description of the process of displaying the retrieved point of interest information.

Referring to FIG. 6, the controller 140 displays a search window through the display unit 150 (S251).

As another example, a search window 282 for performing a search according to the administrative district name 281 is displayed as indicated by reference numeral 280 in FIG. 10.

When the search word is input by the user's selection signal (S252), the controller 140 determines whether the point of interest information corresponding to the search word exists in the point of interest information storage area 113 (S253). If the point of interest information exists, the controller 140 displays corresponding point of interest information (S254). In this case, when there is a plurality of points of interest information, the controller 140 displays the points of interest information in the form of a list in the latest stored order. In addition, the controller 140 may control the navigation processing module 149 to display corresponding point of interest information on the map image.

For example, as shown by reference numeral 250 of FIG. 9, when the category is selected as 'restaurant' 251 and the search key 253 is entered as the search term is entered as 'AAA' 252, FIG. As shown by reference numeral 255 of FIG. 9, 'AAA' points of interest information stored in the point of interest information storage area 113 is searched for and displayed on a map. In addition, when a specific administrative district name is selected, as shown in reference numerals 260 and 265 of FIG. 9, point of interest information 261 and 266 existing in the selected administrative district name are displayed on the map image.

As another example, as shown by reference numeral 280 of FIG. 10, when the administrative region name is selected as 'Gyeonggi-do' 281, and the search key 283 is input while the search word is input as 'AAA' 282. As shown by reference numeral 285 of FIG. 10, guide coordinates of point of interest information corresponding to 'AAA' included in 'Gyeonggi-do' administrative district name are displayed on the map image. Subsequently, when a specific area is selected, guide coordinates 291 of the selected point of interest information are displayed on the map image as illustrated at 290 of FIG. 10.

Subsequently, the controller 140 determines whether a selection signal is input to specific point of interest information among the displayed point of interest information (S255). When the selection signal is input to the point of interest information, the controller 140 controls the position calculation module 147 to compare the current position coordinates with the guide coordinates of the selected point of interest information to calculate a moving distance and a moving time (S256). . Thereafter, the controller 140 controls the navigation processing module 149 to display the current position coordinates, guide coordinates of the selected point of interest information, a moving distance, and a moving time on the map image (S257).

The controller 140 checks whether there is an input of the route guidance request signal (S258), and if so, controls the navigation processing module 149 to perform route guidance from the current position coordinate to the guide coordinate of the selected point of interest information (S259). . For example, as shown by reference numeral 265 of FIG. 9, when specific point of interest information is selected, as shown by reference numeral 270, a path to the guide coordinate of the selected point of interest information 266 is displayed. For example, as shown in reference numeral 290 of FIG. 10, when specific point of interest information is selected, as shown in 295, a path is displayed to guide coordinates of the selected point of interest information 291.

Referring back to FIG. 3, the controller 140 determines whether there is an input of the point of interest information display mode change signal (S260). If there is an input of the display mode change signal, the controller 140 sets the point of interest information display mode to the point of interest information display mode selected by the user's selection information (S270) and performs the above-described step S220.
