However, data such as the shape of an intersection and the number of lanes of intersecting roads may be included in the header information. In addition, the entrance part and the advancing part of the intersection may be set at a predetermined distance before and after a predetermined distance from the side edge of the intersection, that is, a corner where two roads intersect, and the distance from the side edge is different before and after the side edge. It does not matter.
2. Route-passing video file-video file of the section with the intersection as the start point and end point This route-passage video file is a video file with the intersection exit as the start point and the next intersection entrance as the end point. As shown in FIG. 8, the header information added to the route passing video file includes “route name data”, “both-end intersection name data”, “shooting start reference line data”, “shooting end reference line data”, “time” The data is composed of “data” and “average vehicle speed data”.

In this embodiment, the case of a one-way single lane is described as an example. However, data such as the shape of an intersection and the number of lanes of intersecting roads may be included in the header information. The exit and entrance of the intersection may include the shape of the intersection, the number of lanes of the intersecting road, and the like in the header information. Further, in a route having a plurality of lanes, a configuration in which a traveling lane position is also added and stored can be adopted. In such a case where information on a route with a plurality of lanes is added, when the lane is changed, an identification code indicating the lane change, the original lane and the lane after the change, the position and time at which the lane change is started, It is appropriate to configure to store the finished position and time.
3. Route entry / exit video file-Video file for entry / exit to the parking lot (outside the route) or parking etc. on the way Since the reference line data exists at the position to enter / exit on the route, such route entry / exit video file is The captured image data between the reference line data at a position entering and exiting the route and the reference line data next to the reference line data is converted into a video file.

  As the header information added to the route entry / exit video file, as shown in FIG. 9, “route name data”, “zone name data”, “shooting start reference line data”, “shooting end reference line data”, “time data” And “average vehicle speed data”. Such a route entry / exit video file is a file in which the entry / exit points to the roadway are recorded.

  When parking on the street or when the engine is stopped, save the section video file from the time the accessory is turned on to the next intersection or the section video file from the intersection to the time when the accessory is turned off. To do. The start and stop instructions for the vehicle-side system of the present invention are when the key position (not shown) is turned ON or OFF.

If it is at a point other than the roadway when the system of the present invention is started, the point on the route entering the roadway is recorded. Further, when the system of the present invention is at a point other than the roadway at the time of stopping, the point on the route leaving the roadway is recorded.
4). Non-route video file-an image of the vehicle running outside the route such as a parking lot. Such a non-route video file is a video file that starts at a parking lot outside the route and exits the route. That is, a video file from the route until it enters the parking lot and parks (key position is accessory OFF), or a video file that enters the parking lot from the route and parks (key position is accessory OFF) and goes directly to the route Etc.

  As the header information added to the off-route video file, as shown in FIG. 10, "zone name data", "route name data", "shooting start reference line data", "shooting end reference line data", "time data" And “average vehicle speed data”.

  If it is at a point other than the roadway at the start of the system of the present invention, the point on the route going to the roadway is recorded. Further, when the system of the present invention is at a point other than the roadway at the time of stopping, the point on the route leaving the roadway is recorded.

  When classified as the above four types of files of “intersection video file”, “route passing video file”, “route entry / exit video file”, and “outside route video file”, the divided video file shown in FIG. It will be classified as shown in FIG. 11 is a diagram illustrating a correspondence relationship between a running example and a video file type.

  As described above, according to the information distribution service system of the present invention, the captured image data acquired by the vehicles 100, 100 ′, 100 ″ is divided into the video file by the reference line data. The file is compact and linked with location information. Such a video file generated by the information distribution service system of the present invention is excellent in handling on the system.

  In the above embodiment, the example in which the information distribution service center side has the system configuration related to the reference line data as described above has been described. However, the system configuration related to the reference line data is set to each vehicle 100, 100 ′, The video file divided from each vehicle may be uploaded to the information distribution service center in such a manner that it is held at 100 ″.

  Next, a case where a video file is delivered from the video file database 253 to each vehicle 100, 100 ', 100' 'will be described. FIG. 12 is a diagram showing a display example of the image display unit 130 on the vehicle 100, 100 ', 100' 'side in the information distribution service system according to the embodiment of the present invention. As shown in FIG. 12, the positions of receivable images are displayed on the map of the image display unit 130 by icons 131 and 132 for the users of the vehicles 100, 100 ′, and 100 ″. In the image display unit 130, the icons 131 and 132 sequentially move on the map every time the vehicle transmitting the video travels and moves. When the user selects the icon 132 of the video to be received from among them, the system of the vehicle side information distribution service system requests the information distribution service center side system to request the video file of the vehicle corresponding to the icon 132. In response to this request, the information distribution service center side system searches the video file database 253 for the corresponding file from the image database search unit 210, and transmits this from the data distribution unit 232 to the request source vehicle. The vehicle-side system receives this video file and displays it on the image display unit 130 by playing it. According to such an information distribution service system of the present invention, it is possible to visually confirm the traffic jam condition, weather, road surface condition, and the like at locations away from the vehicles 100, 100 ', 100' '. FIG. 13 is a diagram showing a display example on such an image display unit 130 on the vehicle side.

  In the above example, the display example in the image display unit 130 on the vehicle 100, 100 ′, 100 ″ side is shown, but a similar mechanism can be achieved by an information processing terminal such as a personal computer or a mobile phone. The system constituted by these information processing terminals also falls within the scope of the present invention.

  Since the information distribution service system according to the embodiment of the present invention can refer to the video from other vehicles in real time by the above-described mechanism, it is necessary to consider the confidentiality of personal information.

  In the information distribution service system according to the embodiment of the present invention, in consideration of such personal information concealment, only the terminal that has notified the current position of the receiving system operates so that the transmission source vehicle of the video file cannot be specified. Therefore, an icon within a certain range of the receiving terminal is not displayed so that an image cannot be received. It is preferable that the setting of the personal information concealment system can be changed in the information distribution service center side system.

  Such a mechanism for notifying the current position and transmitting video includes the following examples. The vehicle 100, 100 ′, 100 ″ side system is configured by a dedicated GPS device and software, and the terminal unique number, time and current position data are transmitted to the information distribution service center side system as needed. Get the certification. The information distribution service center side system is configured to send other vehicle travel video data and icon data to the terminal side only during the authenticated period. If authentication cannot be obtained, icons of other vehicles and running video data are not transmitted.

  In addition, if a vehicle dedicated to video transmission is set in the information distribution service center side system and a video while the vehicle is traveling is transmitted, it can be an exception to the previous personal information concealment constraint. In addition, by incorporating a video providing service using a fixed camera into the information distribution service system, it is possible to check the video at intersections that are famous for traffic jams, improving convenience. Of course, this fixed camera video can also be an exception to the previous personal information concealment constraint. Thus, it is preferable that only such general video can be used for a terminal that does not notify the current position.

  Next, display of recent videos before and after a specific point by the information distribution service system of the present invention will be described. At the service center of the information distribution service system, the video information transmitted from each vehicle 100, 100 ′, 100 ″ is organized based on the time / position information and stored in the video file database 253. If a specific point is set by a map, an intersection name, an address, etc. at the system terminal, the center can distribute the latest video in the vicinity as needed. Even if there is no other vehicle at the point requested by the user at the current time, the latest video can be confirmed.

  Next, display of recent videos before and after a plurality of specific points by the information distribution service system of the present invention will be described. When a plurality of specific points are set in advance and a route to be passed is set by route search or the like, an image of the specific point on the route closest to the local point is displayed on the image display unit 130. As a display method, a sub-window may be displayed constantly on a part of the screen, or only an icon may be displayed to display an image based on a driver's instruction. When the vehicle passes the specific point being displayed, the specific point on the next route is displayed in the same manner. The video of the next specific point may be switched before or after passing. For example, the vehicle may arrive near a specific point and may be switched at a point where the specific point can be visually confirmed from the vehicle, or the display point may be changed one after another according to a driver's instruction.

Next, route guidance using live-action video by the information distribution service system of the present invention will be described.
At the service center of the information distribution service system, the video information transmitted from each vehicle 100, 100 ′, 100 ″ is organized based on the time / position information and stored in the video file database 253. If the route is set by the system terminal, the passing route is determined based on the information, and if there is an image corresponding to the route, the video file can be transmitted to the user terminal and displayed. If the video file is played back in the order of the route, the route can be explained by the live-action video. By adjusting the playback speed of the live-action video based on the current position information of the vehicle, it is possible to always check the video of the point where the vehicle will run from now on, so it is possible to provide route guidance using the actual video. It is easier to understand if the route to be traveled is indicated by an arrow in this image.

  The display / guidance as described above can also be achieved by an information processing terminal such as a personal computer or a mobile phone, and the system configuration using these information processing terminals falls within the scope of the present invention.

  Hereinafter, supplementary matters for realizing the present invention will be described.

  For the video file database 253 of the information distribution service center side system, it is appropriate to use a storage device such as an HDD array system that can be accessed at random in an instant.

  In addition, because of the capacity of the video file database 253 and the like, all videos cannot be processed depending on the processing capability on the center side, so it is also effective to adopt a concept such as selecting processed videos. At this time, the sorting condition is dealt with by sorting according to the importance of the point.
