In addition, the data collecting means 210 is a location identifier 'B-2' of CCTV, CCTV installation point 'Cheongdam-dong', Gangnam-gu Cheongdam-dong, CCTV installation road 'Youngdong Bridge (B)', CCTV installation road length ' It can collect and store traffic information data such as 1.6km ', speed limit' 60km / h 'on CCTV installation roads, average driving speed' 35km / h ', current traffic volume' 60 ', and' control '.

The data grouping means 220 serves to group the collected image data.

That is, the data grouping means 220 may select image data that may be more useful to the user from among the collected image data in various ways, and group the image data to be reproduced as one video file. Therefore, in transmitting image data collected from a plurality of CCTVs using a unidirectional broadcast channel (DMB), more efficient transmission is possible.

For example, the plurality of CCTVs may be assigned a location identifier according to the installed location, and the data grouping means 220 may first identify the current location of the user, and may be assigned a location identifier associated with the first identified current location. The second CCTV may be identified, and the image data generated by the second identified CCTV may be grouped.

For example, when the user is driving the 'Seongsan Bridge A', the data grouping means 220 obtains the consent of the location tracking from the user in advance through the authentication means 250 and then the user's vehicle. Tracking the location of the installed navigation terminal to first identify the current location of the user, 'Sungsan Bridge (A)', the location identifier 'A-1' associated with the current location of the identified user 'Sungsan Bridge (A)', And second identifying CCTV to which 'A-2' is assigned, and generating image data generated by the second identified CCTV into one file in a group of up / down or left / right.

As another example, a plurality of CCTVs may be given a location identifier according to the installed location, and the data grouping unit 220 identifies the CCTV installed by road using the location identifier, and the image data generated by the identified CCTV Can be grouped.

For example, the data grouping means 220 is a CCTV installed in the 'Sungsan Bridge (A)', CCTV that is given a location identifier 'A-1' and 'A-2' associated with the 'Sungsan Bridge (A)' By identifying the, the image data generated by the identified CCTV can be generated in a single file, grouped up / down or left / right. In addition, the data grouping means 220 identifies a CCTV installed in the 'Youngdong Bridge (B)', a CCTV to which the location identifiers 'B-1' and 'B-2' associated with the 'Youngdong Bridge (B)' are assigned. Then, the image data generated by the identified CCTV can be generated in one file, grouped up / down or left / right.

As another example, the plurality of CCTVs may be given a location identifier according to the installed location, and the data grouping means 220 identifies a CCTV to which a location identifier associated with a control point according to a weather condition or various events is identified, and Video data generated by the identified CCTV can be grouped.

For example, if a weather alert is generated due to the possibility of flooding due to a typhoon or flood and the 'Yongdong Bridge (B)' is controlled, the data grouping means 220 is a control point 'Youngdong Bridge (B)' according to the weather condition. Identify the CCTVs to which the location identifiers 'B-1' and 'B-2' associated with each other are assigned, and generate image files generated by the identified CCTVs in a single file up, down, left, or right. Can be.

In another example, the plurality of CCTVs may be assigned a location identifier according to the installed location, and the data grouping unit 220 may provide a CCTV having a location identifier associated with a traffic jam or a point at which a traffic amount of a predetermined value or more is measured. Identify and group the image data generated by the identified CCTV.

The data grouping means 220 is a habitual congestion section, for example, 'Gupabal Station-Green Translation Section, E-Band-Shinchon Rotary-Hongik University Station Section, Seongsan Elementary School-Hapjeong Station-Sangsu Station, Gunja Bridge-Sindap Station, Sinsa Station-Gangnam Station , Identifying the CCTV to which the location identifier associated with Samsung Station-Gangnam Station, Olympic Boulevard, and Yeongdong Bridge (B) is assigned, and grouping the image data generated by the identified CCTV up / down or left / right, Can be created as a file.

Therefore, the data grouping means 220 can improve the efficiency of the transmission channel when transmitting through a single channel by grouping the image data collected from the plurality of CCTV, the user through a plurality of divided screens CCTV Video traffic information can be checked at once.

The data grouping means 220 uses the collected traffic information data in grouping the image data that may be more useful to a user from the collected image data and then grouping the image data to be reproduced as a single video file. Congestion calculation means 230 may be used to determine the traffic congestion level.

That is, the data grouping means 220 uses the traffic congestion calculated from the congestion calculating means 230 to select and group image data collected from CCTVs installed at a point with high traffic congestion or an adjacent point, thereby providing the user with a traffic congestion degree. It can provide useful information.

For example, the congestion calculating unit 230 may calculate the average congestion time for each road from the collected traffic information data, and calculate the traffic congestion degree based on the calculated average congestion time for each road.

The stagnation time refers to a time that is stagnant compared to the normally defined driving speed. For example, the stagnation time may be calculated as a difference of the time required for driving at the limited speed from the time required for driving at the average traveling speed.

Therefore, the speed limit is 60km / h in 'Sungsan Bridge (A)' with speed limit 60km / h, compared to the point of 'Upward Line of Yanghwa-dong, Yeongdeungpo-gu' where CCTV with location identifier 'A-2' with average driving speed is 50km / h. At the 'Seongdong Bridge (B)', 'Seongdong-gu Seongsu-dong', where CCTV is installed with a location identifier 'B-1' with an average driving speed of 30km / h, a larger congestion time can be seen, and data grouping means 220 may identify a CCTV to which a location identifier associated with a point at which a traffic congestion degree of a predetermined value or more is calculated is assigned and group image data generated by the identified CCTV.

As another example, the congestion calculation unit 230 may calculate the number of objects occupied per screen in the image data generated by the CCTV using the collected traffic information data, and calculate the traffic congestion using the calculated number of objects. Can be. That is, the congestion calculation unit 230 calculates the number of objects (object density) displayed in the screen as the traffic information data is visualized through a predetermined screen, and based on the calculated number of objects (object density). It serves to calculate the degree of congestion.

For example, when the number of objects occupied by one screen is 16 compared to the case where 12 objects occupy one screen in the video data generated by CCTV, the traffic congestion may be approximately 4/3 times higher. The grouping means 220 may identify a CCTV to which a location identifier associated with a point at which a traffic congestion degree of a predetermined value or more is calculated is assigned and group the image data generated by the identified CCTV.

In addition, the congestion calculation unit 230 may calculate a traffic congestion degree through traffic information data such as whether there is an accident or the distance between cars, and the data grouping means 220 may calculate a higher traffic congestion degree using the calculated traffic congestion degree. Image data at a point can be grouped.

Therefore, according to the present invention, by calculating the traffic congestion using the traffic information data received from the traffic information collecting device, by selecting the points where the traffic congestion of a predetermined value or more generated by providing to the user, to provide CCTV video traffic information Can increase the transmission efficiency.

The data processing means 240 processes the grouped image data to correspond to the TPEG standard.

The data processing unit 240 may generate the TPEG image data by dividing and processing the grouped image data by a predetermined size at predetermined time intervals.

For example, the data processing unit 240 generates the TPEG image data by processing the grouped image data in accordance with the TPEG standard for 30 seconds in a 10 minute period, thereby resulting in inefficiency of channel use due to the transmission of a large amount of TPEG image data. In addition, it is possible to provide real-time CCTV video traffic information to the user while solving problems such as data reception performance degradation of the user terminal.

The authentication means 250 serves to authenticate the user. That is, the authentication means 250 may allow transmission of the TPEG image data through the one-way broadcast channel (DMB) to the user whose authentication is approved according to the authentication result. In addition, the authentication means 250 may be authenticated for the location tracking of the user terminal.

The data transmission means 260 transmits the generated TPEG image data to a user using a single channel.

That is, the data transmission means 260 may transmit the generated TPEG image data to a user terminal using a unidirectional broadcast channel, for example, DMB, without a separate return channel such as wireless internet.

The TPEG video data automatically transmitted by the download method through the data transmission means 260 is reproduced on the user's terminal without paying a separate call fee, such as wireless Internet, so that the user can easily access real-time CCTV video traffic information. You can check it.

The traffic information providing system 200 according to the present invention may process the CCTV video traffic information in a streaming form into data of a download method, and provide the user to view a desired CCTV image by using a limited broadcast channel. The traffic information providing system 200 may process and process a CCTV video having an appropriate size to be transmitted at appropriate time intervals in order to overcome limitations of broadcast channels and real-time problems of CCTV video.

Therefore, the traffic information providing system 200 can provide a reliable traffic information such as CCTV video traffic information to the user in real time more easily if the broadcast reception is set without paying the call fee for the wireless Internet. have. In addition, the traffic information providing system 200 is not only suitable for paying the broadcast content, but also may provide a service to a specific brand customer, thereby providing a differentiation point.

It can provide useful information.

For example, the congestion calculating unit 230 may calculate the average congestion time for each road using the collected traffic information data, and calculate the traffic congestion using the calculated average congestion time for each road.

The stagnation time refers to a time that is stagnant compared to the normally defined driving speed. For example, the stagnation time may be calculated as a difference of the time required for driving at the limited speed from the time required for driving at the average traveling speed.

Therefore, the speed limit is 60km / h in 'Sungsan Bridge (A)' with a speed limit of 60km / h, compared to the point of 'Upward Line of Yanghwa-dong, Yeongdeungpo-gu' where CCTV with location identifier 'A-2' with an average driving speed of 50km / h is installed. At the 'Seongdong Bridge (B)', 'Seongdong-gu Seongsu-dong', where CCTV is installed with a location identifier 'B-1' with an average driving speed of 30km / h, a larger congestion time can be seen, and data grouping means 220 may identify a CCTV to which a location identifier associated with a point at which a traffic congestion degree of a predetermined value or more is calculated is assigned and group image data generated by the identified CCTV.

As another example, the congestion calculation unit 230 may calculate the number of objects occupied per screen in the image data generated by the CCTV using the collected traffic information data, and calculate the traffic congestion using the calculated number of objects. Can be.

For example, when the number of objects occupied by one screen is 16 compared to the case where 12 objects occupy one screen in the video data generated by CCTV, the traffic congestion may be approximately 4/3 times higher. The grouping means 220 may identify a CCTV to which a location identifier associated with a point at which a traffic congestion degree of a predetermined value or more is calculated is assigned and group the image data generated by the identified CCTV.

In addition, the congestion calculation unit 230 may calculate a traffic congestion degree through traffic information data such as whether there is an accident or the distance between cars, and the data grouping means 220 may calculate a higher traffic congestion degree using the calculated traffic congestion degree. Image data at a point can be grouped.
