Next, the operation will be described.
When a user determines a video scene to be provided with information, since at least one or more video stream data is stored in the stream data storage unit 1, those video streams are stored using the reproduction information generation unit 2. Desired video stream data is selected from the data (step ST1).
That is, when the user gives a request for selecting video stream data to the reproduction information generation unit 2, the reproduction information generation unit 2 displays an operation screen as shown in FIG. 5, and the user uses a keyboard, mouse, etc. (not shown). When the “stream selection” button on the operation screen is clicked, the reproduction information generating unit 2 pops up a map on which the camera list and camera icons are superimposed on the operation screen.
As a result, the user selects a desired camera by looking at the camera list and map, and designates the ID of the camera.
In addition, the user operates the “shooting time” button on the operation screen to designate the shooting time. If the video scene for providing information is a live video, the current time is specified as the shooting time, and if it is a stored video, the alarm occurrence time is specified as the shooting time. The “shooting time” button also has a function of displaying the shooting time of the video being played back.

When the video scene to be provided is a live video, the reproduction information generation unit 2 refers to the camera management information of FIG. 6 managed by the camera management server 40 and performs live corresponding to the camera ID specified by the user. The multicast address of the encoder device 23 that is the video distribution source is acquired.
As shown in FIG. 6, in addition to the live video distribution source, the camera management information includes supplementary information indicating the place name and landmark where the camera is installed, the camera installation position (latitude and longitude), Related information indicating the installation information indicating the shooting range of the camera, the rain gauge in the vicinity of the camera, the ID (identification information) of the facility, and the like is described for each camera, and is used for acquiring content elements described later.

When the video scene to be provided is an accumulated video, the reproduction information generation unit 2 refers to the video recording management information of FIG. 7 managed by the video server 31 and uses the camera ID and shooting time specified by the user. The network address and video ID (video data identification information) of the video server (if there are a plurality of video servers) managing the corresponding video stream data are acquired.
There are two types of video recording management information. In the example of FIG. 7, video recording management information for endless recording and video recording management information for storage recording are shown.
The video recording management information for endless recording includes a camera ID, a video ID, a network address of the video server 31, a recording time (time length) from the current time, a recording parameter indicating an encoding method, an image size, and the like. .
The video recording management information for storage recording includes supplementary information such as a video ID, a camera ID, a network address of the video server 31, recording parameters, IDs and comments of stored and recorded events, and the like.

When the reproduction information generation unit 2 acquires the multicast address of the encoder device 23 that is the distribution source of the live video or the network address of the video server 31 that is the management source of the stored video as described above, Video stream data of the video is acquired, and the video stream is reproduced in the video area of the operation screen (step ST2).
Accordingly, the user looks at the video stream and searches for a video scene for which information is provided.
That is, the user searches for a video scene that provides information by performing playback / stop / rewind / fast-forward of a video by operating a “video playback” button on the operation screen.
When the user decides the video scene to provide information, the user operates the “Cut” button on the operation screen to specify the shooting time of the representative screen of the video scene, the start shooting time, the end shooting time, etc. The segment of the video scene in the video stream data is designated.
The user also inputs the title and description of the video scene as necessary.

  When the user designates a video scene cut-out section (step ST3), the playback information generation unit 2 performs a camera ID designated by the user and a playback time indicating the video scene cut-out section (on the representative screen) as shown in FIG. Playback information including a shooting time, a start shooting time, an end shooting time), a title, a description, and the like is generated, and the playback information is output to the content acquisition unit 5 (step ST4).

Upon receiving the reproduction information output from the reproduction information generation unit 2 (step ST5), the content acquisition unit 5 inputs the template information stored in the template information storage unit 3 (step ST6).
Here, as shown in FIG. 9, the template information is composed of content definition and layout definition information. For each content element constituting the multimedia document to be created, the content ID (content element) of the content element is included. Information), content definition, and layout definition information are described.
The content definition defines the content element acquisition destination and range, and the layout definition includes the content element screen layout (position on the screen where the content element is placed), the display time of the content element, and the media Types (for example, characters, moving images, vectors, graphics, links, graphs, etc.) are defined.
The template information in FIG. 9 corresponds to the screen of the multimedia document in FIG. 3, and the template information has a layout suitable for the content of information to be provided (disaster type and situation), the person to whom the information is provided, and the like. The person who has a design sense creates a plurality of template information in advance.
When the reproduction information generation unit 2 generates reproduction information, the user selects appropriate template information from a plurality of prepared template information.

When the template information is input from the template information storage unit 3, the content acquisition unit 5 refers to the template information and identifies content elements that need to be included in the multimedia document to be created (step ST7).
In the example of FIG. 9, content definition and layout definition information related to eight content elements are included in the template information, so that it is recognized that eight content elements need to be included in the multimedia document to be created.

When the content element that needs to be included in the multimedia document to be created is specified, the content acquisition unit 5 specifies the “acquisition destination” of the content definition in the content element, and acquires the content element from the acquisition destination (step) ST8).
For example, the “title” of the content ID 1 and the “description text” of the content ID 2 are generated by the reproduction information generation unit 2 because the acquisition destination is defined as “reproduction information” and the medium is defined as “character”. Character information of “title” and “description” included in the reproduced information of FIG. 8 is acquired as content elements.

In addition, since the acquisition destination of “video” of content ID 3 is defined as “reproduction information” and the medium is defined as “moving image”, the reproduction information of FIG. 8 generated by the reproduction information generation unit 2 is added. The included “camera ID” and “reproduction time” are acquired.
Then, the video server 31 is inquired of the video server managing the video stream data corresponding to the camera ID and playback time and the video ID, and the video scene corresponding to the video ID is used as a content element from the video server. get.

  In addition, since the acquisition destination of “map” of content ID 4 is defined as “map server” and the medium is defined as “vector”, map data as vector data is acquired from the map server 36 as map content. To do. Note that, as shown in the content definition, the map acquisition range is a range of 500 m square from the camera installation position described in the reproduction information. The camera installation position can be acquired from the camera ID of the reproduction information and the camera management information of FIG.

Since the acquisition destination of the “camera icon” of the content ID 5 is defined as “camera management server”, the camera installation position and shooting range are acquired from the camera management server 40, and the camera icons registered in advance are acquired. A camera icon corresponding to the camera ID is acquired as a content element.
In addition, since the content ID 6 and the content ID 7 are related links, the acquisition destination as the link destination is defined as “facility management server”, and the acquisition range is defined as “camera management information description”. The described facility ID is acquired, and the link information composed of the location of the facility management server and the facility ID is used as the content element.

In addition, since “measurement data” of content ID 8 is defined as “measurement server” as the acquisition destination and “graph” as the medium, measurement data is acquired as a content element from the measurement server 34. The measurement data is rainfall data managed by the measurement server 34 and can be acquired from the rain gauge ID described in the related data of the camera management information, and the acquisition range is described in the reproduction information. It will be one hour before and after the representative time.
The content acquisition unit 5 repeatedly performs the processes of steps ST7 to ST8 until all content elements that need to be included in the multimedia document to be created are acquired (step ST9).

When the content structuring unit 6 acquires all the content elements that the content acquisition unit 5 needs to include in the multimedia document to be created, the document structuring unit 6 obtains layout information from the template information stored in the template information storage unit 3 in FIG. A multimedia document is created by spatially and temporally laying out all content elements in accordance with the layout information.
That is, the document structuring unit 6 specifies the coordinates {(Xs, Ys), (Xe, Ye)} on the multimedia document in which the content elements are arranged from the “screen layout” of the layout definition in the template information, and the layout. The time at which the content element is displayed is specified from the “display time” in the definition, and presentation information indicating these coordinates and time is created (step ST10).
Here, in the “display time” of the layout definition, in addition to the absolute time at which the display of the content element is started, the relative time from the display time of the other content element until the display of the content element is started. be written. In addition, “end” indicating that the content element is displayed to the end may be described.

When creating the presentation information as described above, the document structuring unit 6 spatially and temporally lays out all the content elements extracted by the content acquisition unit 5 in accordance with the presentation information to create a multimedia document. Created and output document information indicating the multimedia document in the form of a file or the like (step ST12).
However, for example, when the size of the content element extracted by the content acquisition unit 5 is different from the window size, the document structuring unit 6 performs content conversion processing such as enlarging or reducing the size of the content element (step ST11). ).

Here, in the file structure of the multimedia document information, as shown in FIG. 10, presentation information is arranged at the head, and content elements are arranged thereafter.
For example, a content element with a small data size, such as text or numerical values, records the data of the element itself on a file, but a content element with a large data size, such as a video or a map, records the data of that element. Link information (content link) that refers to the video server 31 or the map server 36 being recorded is recorded on the file.

  As is apparent from the above, according to the first embodiment, the camera included in the reproduction information generated by the reproduction information generation unit 2 with reference to the template information stored in the template information storage unit 3. A content acquisition unit 5 that acquires the video stream data of the clipped section corresponding to the ID as a content element is provided, and the content element acquired by the content acquisition unit 5 is laid out according to the layout information defined in the template information. Since it is configured to create a media document, there is an effect that a multimedia document having a good appearance can be created in a short time regardless of the user's experience and design sense.

  Further, according to the first embodiment, the acquisition source and layout information of content elements (for example, other video stream data, explanation documents, measurement data, maps, etc.) other than the video stream data defined in the reproduction information are included. When it is included in the template information, when the content acquisition unit 5 acquires the video stream data, the content element other than the video stream data is also acquired. Therefore, the data related to the video stream is also automatically acquired. Thus, the related data can be included in the multimedia document.
