DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a system according to an embodiment realized by the present invention. The video information display system 1 shown in FIG. 1 is accessed by an image information display system 10 realized by executing a program using hardware resources of a computer and a line such as a communication line from the image information display system 10. It is composed of a video information database 3 that is provided. The image information display system 10 extracts a video file that matches the search condition from the video information database 3 based on the search condition set by the user, and extracts it from the acquired information such as the attribute information of the video file, the search condition, etc. A score calculation unit 11 for calculating a score for the video file, a layout calculation unit 12 for calculating a display position and a display size in the display screen for the sample image of the video file from the calculated score, and information on the calculated layout A layout output unit 13 that actually arranges the sample image on the screen and passes information to the client 2 to be displayed is provided.
[0010]
The video information database 3 includes a plurality of video files and various data indicating attribute information of each video file (video file ID (recognition code), sample image name, title, description, length, format, genre). , Creation date / time, importance) and a video information database including sample images of each video file. The importance is the value of how important the video information is to the user or information provider. Specifically, the user, a specific value uniquely set by the information provider, and the content information provider Possible values include a value proportional to the commercial price paid, the number of keywords preferred by the user included in the title or description, and a value proportional to the date created. FIG. 2 shows an example of management data in the video information database 3. The video information database 3 stores ID information for identifying a video file and various attribute information as described above accompanying the video file.
[0011]
The operation of the video information display system 1 will be described below. FIG. 3 is a processing flow of the score calculation unit 11. In step S101, a video information data list is created from the video information database 3 based on the search conditions of the user. The video information data list is a list of file IDs of video files extracted in accordance with search conditions and all or part of attribute information as shown in FIG. 2 corresponding to the extracted video files. It is. As the search condition, a search condition such as one containing a set keyword, one created after a set date and time, one of a specific genre, and the like can be considered.
[0012]
In step S102, the scores of all the video information included in the video information data list are calculated from the video information data list created in step S101 and various conditions set. The set conditions are the number of keywords included, the importance acquired from the video information database 3, the creation date and time, and the like.
[0013]
A method is also conceivable in which the rank is determined from the numerical values obtained above, and a score determined by the rank is set in advance and used as the score.
[0014]
In step S103, the score calculated in step S102 is stored on a memory or a hard disk and transferred to the layout calculation unit 12. FIG. 4 is a processing flow of the layout calculation unit 12.
[0015]
In step S201, the score calculated by the score calculation unit 11 is acquired, and the video information file IDs are rearranged in the score order from the acquired score. In step S202, the obtained score is normalized by dividing the obtained score by the value having the highest score. The total score is also calculated.
[0016]
In step S203, each sample image is displayed when the size of the sample image of the video information file having the highest score is set to 1 from the aspect ratio of the screen to be output set in advance and the value calculated in step S202. Calculate the length of the layout. The aspect length calculation method is obtained by dividing the total value calculated in step S202 by a value obtained by multiplying the preset aspect ratio of the screen and multiplying the obtained square root by the aspect ratio value. .
[0017]
In step S204, based on the score calculated in step S202, an image is added in the right direction as shown in FIG. As a method for adding an image, the upper left image is a square having a size of 1 × 1, and thereafter, n squares each having a size of 1 / n are added. The size of the square to be added is the difference between the sum of the scores from st to st + n and the value of (1 / n) ^ 2 * n (= 1 / n), where st is the first number of the added image. Is calculated to obtain n with the smallest value, and st is set to st + n + 1. This is added until the length in the horizontal direction calculated in step S203 is exceeded.
[0018]
In step S205, based on the score calculated in step S202, an image is added downward as shown in FIG. As a method of adding an image, if the lateral length finally added in step S204 is a variable len, n squares each having a length of len / n are added. As for the size of the square to be added, n is obtained in which the difference between the total score of the normalized image and the area of the square to be added is small as in step S204. Continue until there are no more images to add. If there are no more images to add, it is assumed that the ones with the smallest score are connected, and n is obtained.
[0019]
In this way, the calculated square size and coordinates of the image, the ID of the video file that is the source of the image, and the information of the sample image are recorded as layout information on a storage medium such as a memory or a hard disk, and a layout output unit 11 is handed over.
[0020]
FIG. 5 is a processing flow of the layout output unit 11. In step S301, the layout information calculated by the layout calculation unit 12 is acquired. In step S302, the size and coordinate information included in the layout information acquired in step S301 is changed to a size that matches the actual sample image to aspect ratio and the size of the output display screen. In this process, the ratio of the overall horizontal length obtained in step S204 and the horizontal length actually displayed is obtained, and the numerical value of the layout information is changed by applying the scale.
[0021]
In step S303, a layout is created based on the numerical value of the layout information changed in step S302 and information on the format of HTML (Hyper Text Markup Language) or image that the client can display information on the image (sample image), Send to client.
[0022]
The above embodiment shows an example of the embodiment of the present invention, and the present invention is not limited to the above. For example, by excluding the video information database 3 from the configuration of the present invention, the image information display system 10 has a function of accessing a similar arbitrary or designated database, so that the image information display system 10 alone can also store sample images. It can be established as viewed. Further, for example, each component in the image information display system 10 is distributed and arranged via a network or the like, or all or part of the video information database 3 (for example, a video file) in the image information display system 10 The database of attribute information and sample images (except for) is provided alone or in duplicate, or the image information display system 10 has a function of managing distribution of video files in the video information database 3 to the client 2. In addition, a configuration in which a still image and a short-time moving image can be output as a sample image can be considered as an embodiment of the present invention. The present invention also includes a computer and a program executed by the computer. The program can be distributed via a computer-readable recording medium or a communication line.
