It is a block diagram showing composition of a video server system concerning an embodiment. It is a chart figure showing a generation flow of an item material concerning an embodiment.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing the configuration of a video server system 100 according to the present embodiment. As shown, the video server system 100 comprises a video server 10, an editor 20 and a display 30.

  The display 30 is connected to the editing machine 20, and includes a display 31 for displaying a material list for displaying a material list, and a display 32 for editing for editing a broadcast material for a program from the material list. It has the function as

  The video server 10 has a WEB server function, and the editing machine 20 has a WEB client function (WEB client unit 23). The video server 10 and the editing machine 20 are connected by these functions. Although a plurality of editing machines 20 are often connected to the video server 10, only one editing machine 20 and one display 30 connected to the editing machines 20 are shown here.

  The video server 10 has general functions such as a capture function, file system function, relational database function, storage device, communication function (WEB server function etc.), and a plurality of materials input from a camera or VTR etc. It records and records metadata (basic information and detailed information) associated with materials. The metadata may be included in the data of the material itself, or may be stored separately from the data of the material.

  The basic information is, for example, information of a material including a material ID, a title, a comment, shooting information such as a shooting date and time, recording information such as a recording date and time, and a thumbnail. Also, the video server 10 broadcasts (on air) the broadcast material for a program (content in which item materials, various materials, and the like are collected) generated by the editing machine 20.

  The detailed information is, for example, various information on the broadcast work workflow such as In point (insertion start point), Out point (insertion end point), copyright information, dubbing history, caption, deletion restriction date, broadcast restriction date, etc. Contains information that is updated without direct manipulation of the material.

  The editor 20 acquires the material from the video server 10 based on the user operation on the display 30, and edits the material into a program broadcast material. The edited program broadcast material is again recorded on the video server 10 and aired.

  Specifically, the editing machine 20 acquires a desired material list from the video server 10 and displays the material list application unit 21; and an editing application unit 22 edits a program broadcast material from the displayed material list; And a WEB client unit 23.

  When the material list application unit 21 receives a material list request from the function of the console of the material list display 31, the material list application unit 21 collects the material list and outputs it to the Web client unit 23.

  The editing application unit 22 displays the basic screen having a material preview area, a timeline display area, and the like, a material list screen, and a material detailed information screen in an operable manner on the display 30 as basic functions.

  For example, the OnDragDrop event handler is set in the material list screen, it is determined whether the information held in the clipboard is the format of the material ID, and if the format matches, the video server 10 identified by the material ID Mount the file stored in. This mount allows the user to edit the material on the editing display 32.

  The Web client unit 23 receives a material list request from the material list display 31, and transmits the material list to the material list display 31.

  Here, in the video server system 100, a basic procedure until the editor 20 displays the basic information and the detailed information of the material will be briefly described.

  When the user designates a search condition from the material list display 31 and makes a display request of the material list, the material list request is transmitted from the material list display 31 to the editing machine 20. When the editor 20 receives the material list request, the material list application unit 21 transmits the material list request to the video server 10.

  When receiving the material list request, the video server 10 transmits, to the editing machine 20, material list data in which basic information of each material for the specified search condition is collected, as a response to the material list request.

  When the material list application unit 21 of the editing machine 20 receives the material list data, it displays the material list data on the material list screen of the material list display 31. The material list display display can be performed by the user specifying the material ID of the basic information one by one from the material list screen displayed on the material list display 31, for example. A request for detailed information is sent from 31 to the editor 20. When the material list application unit 21 of the editor 20 receives the detailed information request, the material list application unit 21 transmits the detailed information request to the video server 10.

  When receiving the detailed information request, the video server 10 transmits detailed information data, which is detailed information of each material for the designated search condition, to the editor 20 as a response to the detailed information request.

  When the material list application unit 21 of the editing machine 20 receives the detailed information data, the material list application unit 21 displays the detailed information data on the material detailed information screen of the material list display 31.

  The material list application unit 21 mounts the material of the video server 10 so that the material stored in the video server 10 can be accessed from the editing display 32. By this mounting, the editing display 32 can perform editing using the material stored in the video server 10.

Subsequently, the characteristic function in the present embodiment, that is, the editing function of the item material in the editing application unit 22 will be described. Details will be described next, but the item material editing function has the following features.
(1) Mark the use of item digest (digest) when editing each material. It automatically detects a specific image or a position that suddenly becomes loud by image recognition and voice recognition as a key.
(2) Create editing data for item material based on the usage of each material and the broadcast playlist. In addition, telop data is created based on the metadata of the material.
(3) At the start of editing the item material, the materials are arranged in the order of broadcasting based on the result of the above (2), and an editing timeline to which telops are added is developed. Editors can check and revise the content. The change of usage can use the automatic detection function as in the above (1).

  The editing application unit 22 includes an item material mark unit 51, an item material management unit 52, a development unit 53, a telop data creation unit 54, a style storage unit 55, and a prediction unit 56.

  The item material mark portion 51 marks the use as an item material (digest) of each material. As described above, in a news program or the like, editing of each material constituting the program is performed in parallel, and the configuration of the program such as the broadcast order is determined separately from the editing of each material. When editing of each material is completed, item material to be broadcasted at the beginning of the program is created, and a telop is added. In the present embodiment, the item material mark unit 51 has an automatic mark function as well as a manual (visual observation by the user) mark function, and uses a specific image or a sudden loud area as a key by image recognition or voice recognition. As mark, mark (mark point) automatically detects.

  The item material management unit 52 manages data of the mark points of usage marked by the item material mark unit 51, and creates editing data and telop data of the item material based on the usage of each material and the broadcast playlist. . The item material management unit 52 refers to the metadata of the item material when creating the telop data.

  When editing the item material, the expanding unit 53 arranges the item materials in the order of broadcasting based on the telop data, and expands an editing timeline to which the telop is added. Further, when editing the item material, the expanding unit 53 automatically expands the item material editing timeline based on the item material editing data and the telop data. The editor confirms the expanded contents and makes adjustments as necessary. The change of use, for example, executes an automatic detection function of the easy-to-use mark points to display candidate points in a selectable manner.

  The style storage unit 55 registers and holds the display style of the telop. The expansion unit 53 designates a display style by telop data, and automatically reflects the display style with reference to the style storage unit 55 at the time of editing and expansion.

  The prediction unit 56 edits in a state in which each material is read in advance, and predicts an image required in advance at the start of editing from the editing history. Therefore, the developing unit 53 uses the function of the prediction unit 56 to collectively deploy (predictably display) the predicted materials. Here, the prediction unit 56 predicts the necessary material from the words included in the news manuscript, the actual video content, the audio included in the video, and the statistics of the material actually used for the news.

FIG. 2 is a chart showing the generation flow of item material.
First, in the editing machine 20, editing operations for each material are performed in parallel (S10). Here, the material A, the material B and the material C are used as broadcast materials. The item material mark unit 51 automatically marks the use as an item material (digest) of each material on the basis of a specific image, a volume, or the like. The item material management unit 52 manages data of mark points. As a result, data is generated in which usage preferences are added to each of the material A, the material B, and the material C.

  Next, item material editing data is created (S20). Specifically, the expanding unit 53 generates item material editing data based on the result of the editing work (S10) of each material and the broadcast playlist in the broadcast order determination process. The item material edit data is a list of which material is used as the broadcast timing (start time; end time). Further, the telop data creation unit 54 creates telop data based on the metadata of each material (here, the material A, the material B, and the material C). At this time, the telop data creation unit 54 refers to the style storage unit 55 to determine the telop style.

  Next, the developing unit 53 arranges the respective materials in the order of broadcasting, and develops an editing timeline to which telops are added (S30). At this time, the editor confirms the contents and changes the usage if necessary. After completion, the deployment unit 53 outputs the broadcast material (item material, material A, material B, material C) to the video server 10 via the WEB client unit 23, and the video server 10 finally receives the desired timing. And broadcast based on the broadcast playlist (S40).

  As described above, when the material is edited, the usage for the item material is automatically marked, so that the workload of editing the item material can be reduced. In addition, the editors of each material mark usage points, so that it is possible to reliably reflect the parts that the editors want to show without mistakes.

  Subsequently, the function of the prediction unit 56 will be described. According to a general technique, when editing a video, an editor (user) needs to search for a target video from the material list. In the search, (A) program name (B) date (C) title and subtitle are specified, and a target image is searched while performing previewing. Usually, you need to find the material you need at the start of editing. Even if you search, the results of the preview may not be the desired material or may not actually be found.

  Therefore, in the present embodiment, the prediction unit 56 of the editing machine 20 predicts in advance necessary images, and collectively provides them to the editor. That is, information that has not been used to classify materials (words included in news manuscripts, actual video content, audio included in video, statistics of materials actually used for news, etc.) From), predict the required materials. Based on the classification result, the materials required at the start of editing are provided collectively to the user. The prediction technology is not particularly limited, but it is possible to provide more desirable candidate materials for the editor by using a learning function such as an AI technology (deep learning) which has recently been improved in accuracy.

  That is, it is possible to predict the material required at the start of editing from the past editing history, and to start editing while reading the material in advance. By this, the editor can significantly reduce the time and effort of searching for the material by itself. In addition, the learning function makes it possible to find out more appropriate materials than those recognized by the editor.

  The present invention has been described above based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to the combination of the respective constituent elements, and such modifications are also within the scope of the present invention.
