As described above, in this embodiment, the database 6A (6B) is provided in the assembly image information providing system 10, and the assembly information and the corresponding scene information are stored in the database 6A (6B) for each local government. And a video storage unit 9A (9B) for storing video data, and analyzing a service request from the user terminal received by the web server unit 31 by the PRS unit 32. Then, the APL unit 52 is instructed about the local government to be processed and the contents of the necessary processing.
The B management unit 51 searches the database 6A (6B) to obtain necessary parliamentary information on the local government.

Then, the search result is notified to the PRS unit 32 via the APL unit 52, and the PRS unit 32 creates a service providing screen including the desired congressional information and the link information to the corresponding video data. The image is transmitted from the Web server unit 31 to the user terminal 30, and in response to a video request from the user terminal 30 based on the service providing screen, the PRS unit 32 issues a video distribution instruction to the video management unit 81, and responds to the instruction. The obtained video data is obtained from the video storage unit 9A (9B) and is distributed from the video management unit 81 to the user terminal 30.

As a result, it is possible not only to publish parliament information by text information or a photograph (still image) on a document or a screen, but also to provide an image of a parliamentary exchange (video). Therefore, the user can easily browse a lot of information that cannot be transmitted by fixed parliament information such as text information and photographs, for example, information full of a sense of reality, such as a heated state of the parliament and nuances of remarks.

Further, compared with the case where the assembly information is managed and disclosed manually, much time and labor are not required until the assembly information is disclosed, and the information can be provided efficiently and promptly. Therefore, an information providing service that is easy for the user to use can be realized. In addition, compared to a case where a local government introduces its own system and manages electronic data in a database, the system can be shared by a plurality of local governments, and the necessary cost can be greatly reduced. Further, the system can be managed by an administrator who is familiar with the system, and a highly reliable information providing service can be realized.

In this embodiment, the case where two PRS servers 3A and 3B each having a Web server unit 31 and a PRS unit 32 are described as an example, but the present invention is not limited to this. The configuration only needs to have one or more PRS servers. As shown in FIG. 1, two or more PRS servers are provided,
Executing the load balance function and the failover function by using the above function makes it possible to avoid problems caused by uneven processing loads and to take appropriate and prompt actions when an abnormality occurs. In particular, in the present embodiment in which parliamentary information of a plurality of local governments is provided by the same system, the frequency of access is high, which is extremely effective.

In this embodiment, the DB management unit 51
And two APL servers 5A and 5B each having an APL unit 52 and two databases 6A and 6B corresponding thereto are described as an example. However, the present invention is not limited to this. The configuration only needs to have one APL server and one database. In addition, as shown in FIG. 1, two sets each including an APL server and a database are provided, and the same parliament information is registered in each database unit.
In the event of an abnormality, by using the other set by the switching connection unit 4, the database can be duplicated, and the reliability of the system can be greatly improved with a simple and inexpensive configuration.

In this embodiment, the video management unit 81
Has been described as an example in which two media servers 8A and 8B having the following and two video storage units 9A and 9B corresponding to the two media servers 8A and 8B are provided. However, the present invention is not limited to this. Only one media server and one video storage unit are required. As shown in FIG. 2, two sets each including a media server and a video storage unit are provided, and the same parliamentary information is registered in each video storage unit. By using the other pair by the switching connection unit 7, the image storage unit can be duplicated, and the reliability of the system can be greatly improved with a simple and inexpensive configuration.

Next, referring to FIG.
A registration of parliament information and video data in A, 6B and video storage units 9A, 9B will be described. In this assembly image information providing system 10, databases 6A and 6B
Is registered in advance for each of. FIG.
9 is a flowchart showing an information registration procedure. First,
At the time of the congress, the contents of remarks and proceedings are recorded by stenography and recording, and photographed by the video capturing device 12 or another video camera (step 150).

Subsequently, the recorded contents are converted into electronic data (character information) using a personal computer or the like by using an outsourcing service, and the photographed contents are processed by the image processing device 11 into image data (image data). (Step 151). Then, scene information for associating the electronic data, that is, the character information, with the video data is generated (step 152). The scene information includes a video file name corresponding to the congress information, time position information in which the content of the congress information is recorded in the video file, and the like.

The obtained character information and scene information are registered equally in both the databases 6A and 6B by the system administrator (step 15).
3). For video data (video files),
The system administrator registers equally in both the video storage units 9A and 9B (step 154).

When registering new character information and scene information in the databases 6A and 6B, in the assembly image information providing system 10, the DB management unit 51 of each of the APL servers 5A and 5B performs data configuration management processing as maintenance work. FIG. 5 is a flowchart showing a data configuration management procedure. First, the system administrator sets the APL server 5A,
After controlling the 5B to stop the system monitoring function (step 160), the service provision is stopped (step 161). This system monitoring function
It is a function to automatically monitor whether the assembly image information providing system is operating normally, and operates continuously when providing services.

Subsequently, for the new local government, the local government is registered in the local government management table (file) in the databases 6A and 6B (step 162), and the information is registered in the above-described information corresponding to the local government in the databases 6A and 6B. The obtained character information and scene information are appropriately arranged (step 163). Then, the file falsification check database provided in the databases 6A and 6B is updated (step 164). This file tampering check database stores check information for checking the validity of each file arranged in the databases 6A and 6B, and generates new check information every time the database is changed. Then, the file tampering check database is updated.

Thereafter, the APL servers 5A and 5B are controlled to restart the service provision (step 16).
5) The system monitoring function is restarted (step 166), and a series of data configuration management processing ends.
The assembly image information providing system 10 performs such information registration processing and data configuration management processing in the databases 6A and 6B.
Update and register new parliamentary information by doing the same for both.

Regarding the system monitoring function,

/ Analyze and aggregate memory usage and access status,
It is output as an LM file.

In addition, as a system monitoring function, there is a function of automatically monitoring for file tampering on a regular basis, rebooting the server when an abnormality is found, and notifying the system administrator as necessary. In this function, a predetermined tampering detection tool is used. This tool compares the check information (for example, a hash value, etc.) for each file managed by the file tampering check database provided in the databases 6A and 6B with check information similarly generated from each file at that time. It determines whether the file has been tampered with and outputs the result as a log file. Therefore, the APL server 6
A and 6B automatically execute the above tool periodically and analyze the obtained log file to automatically detect falsification of the file.

Further, as a system monitoring function, there is a function of automatically monitoring services / processes on a regular basis, rebooting the server when an abnormality is found, and notifying the system administrator as necessary. In this function, PRS
The servers 3A and 3B monitor the normal operation of the Web server unit 31 and the abnormal startup of the CGI program for realizing various services. The APL servers 6A and 6B monitor the normal operation of the DB management unit 51.
