In step S <b> 201, the display device arrangement information acquisition unit 102 acquires arrangement information of each display device 109. More specifically, the display device arrangement information acquisition unit 102 causes the user to input arrangement information of each display device 109, for example, and acquires the input arrangement information.
FIG. 5 is a diagram illustrating an example of arrangement information. Index is the identification ID of each display device 109, which is the same as the specification information in FIG. The X-axis coordinate is the X coordinate of the lower left of each display device 109 when the lower left of the multi-display composed of a plurality of display devices 109 is 0. The Y-axis coordinate is the Y coordinate of the lower left of each display device 109 when the lower left of the multi-display composed of a plurality of display devices 109 is 0.

More specifically, the combination criterion setting unit 107 causes the user to select a selection criterion and sets the selection criterion selected by the user. As described above, in the present embodiment, the combination reference setting unit 107 is described as having set a “combination in which the size of each video data is close while maintaining the aspect ratio (maintaining the aspect ratio of each content data)”. I do.
The display control system performs when the above operation is started.

FIG. 6 is a flowchart illustrating an example of processing when video data is distributed.
First, the output processing of video data will be described by taking as an example the case where one standard size video data is distributed.
In step S301, the video data change detection unit 103 determines whether there is no change in the distributed video data. When it is determined that there is no change in the distributed video data, the video data change detection unit 103 repeats the process of step S301, and when it is determined that there is a change in the distributed video data, the process proceeds to step S302. Here, the video data change detection unit 103 determines that there is a change in the distributed video data when detecting a change in the distributed video data (a change in the number of video data or the aspect ratio of the video data).

  In step S302, the data analysis unit 104 analyzes the video data, and calculates the number of video data to be output and the aspect ratio of the video data. That is, the data analysis unit 104 specifies that there is one video data to be output and that it is a standard size. This video data is hereinafter referred to as video data α.

In step S303, the display area determination unit 105 determines a combination of display areas of the video data α based on the specification information, the arrangement information, the selection criteria, the number of video data, and the aspect ratio.
Here, the specification information is the specification information acquired in step S200. Further, the arrangement information is the arrangement information acquired in step S201. The selection criterion is the selection criterion set in step S202. The number of video data and the aspect ratio are the number of video data and the aspect ratio calculated in step S302.

  As a method of determining the combination, for example, the display area determination unit 105 holds a combination of display areas in accordance with the size and number of video data for each shape of the display area in advance. Then, the display area determination unit 105 selects a combination from the combinations held based on the specification information, the arrangement information, and the data information of the video data (number of video data and aspect ratio). Extract. Then, it is assumed that the display area determination unit 105 determines one combination from the extracted combinations based on the selection criterion. However, the display area determination unit 105 may determine the combination based on the display area determination algorithm using the specification information, the arrangement information, the selection criterion, the number of video data, and the aspect ratio. good.

  FIG. 7 is a diagram (part 1) illustrating an example of a combination. Index is an identification ID for identifying a combination. The video data is an identification ID that identifies video data to be output. The X and Y axis coordinates are the display coordinates at the lower left of the video data. The X and Y axis sizes are video data display sizes. FIG. 8 shows an example when the video data α is displayed with the combination Index1. FIG. 8 is a diagram (part 1) illustrating an example in which video data is displayed on a multi-display. Since only one standard-size video data is output, the combination is only the combination Index1 shown in FIG. Based on the selection criterion determined by the combination criterion setting unit 107 in step S202, the display region determination unit 105 determines a combination of display regions. The selection criterion is “a combination in which the size of each video data is close while maintaining the aspect ratio”, but since the combination shown in FIG. 7 is only one combination of Index1, the display area determining unit 105 Select and set. Therefore, the display area of the video data α is No. in FIG. 1

  Returning to the description of FIG. 6 again, in step 304, the data display unit 106 obtains the display location of the video data α from the display area determination unit 105. A display command is issued to the multi-display through the display device input / output unit 108 so that the video data α is displayed at the position 1. In response to a display command from the data display unit 106, the display device input / output unit 108 outputs video data to the corresponding display device 109 constituting the multi-display.

Next, video data output processing when one vista-sized video data is added will be described.
In step S301, the video data change detection unit 103 changes that the video data from one standard-size video data has changed into two, a standard-size video data and a Vista-size video data. Is detected. Then, the video data change detection unit 103 advances the process to step S302.

  In step S302, the data analysis unit 104 analyzes the video data, and calculates the number of video data to be output and the aspect ratio of the video data. That is, the data analysis unit 104 specifies that there are two pieces of video data to be output, and that the added video data is Vista-size video data. This added video data is hereinafter referred to as video data β. That is, there are two video data to be output: video data α and video data β.

  In step S303, the display area determination unit 105 determines a combination of the display areas of the video data α and the video data β based on the specification information, the arrangement information, the selection criterion, the number of video data, and the aspect ratio. To do.

  FIG. 9 shows an example of a combination that the display area determination unit 105 has selected based on the specification information, the arrangement information, the number of video data, and the aspect ratio. FIG. 9 is a diagram (part 2) illustrating an example of the combination. FIG. 10 is a diagram illustrating an example in which video data α and video data β are displayed on a multi-display with combinations Index1 to Index4.

That is, there are four combinations shown in FIG. 9 for outputting one standard size video data and one Vista size video data.
The display area determination unit 105 determines one combination according to the selection criterion selected by the combination criterion setting unit 107 in step S202. The selection criterion selected by the combination criterion setting unit 107 in step S202 is “a combination in which the size of each video data is close while maintaining the aspect ratio”. Therefore, the display area determination unit 105 selects Index2 that best meets the selection criteria from the combinations shown in FIG. That is, the display area determination unit 105 sets the display area of the video data α to No. 2 of Index 2 in FIG. 1 and the display area of the video data β is No. 1. 2.

  In step 304, the data display unit 106 acquires the display location of the video data α and the video data β from the display area determination unit 105. Then, the data display unit 106 displays No. 2 of Index 2 in FIG. 1, no. A display command is issued to the multi-display through the display device input / output unit 108 so that the video data α and β are respectively displayed at the position 2. The display device input / output unit 108 receives the command of the data display unit 106 and outputs video data to each display device 109 of the multi-display.

  That is, the video data α displayed using the nine screens of the display device 109 is reduced to four screens, and the video data β is displayed using the six screens of the display device 109.

Next, the video data output process when the vista size video data β is changed to the standard size video data will be described.
In step S301, the video data change detection unit 103 detects that a total of two video data, one standard-size video data and one Vista-size video data, has changed to two standard-size video data. To do. Then, the video data change detection unit 103 advances the process to step S302.

  In step S302, the data analysis unit 104 analyzes the video data, and calculates the number of video data to be output and the aspect ratio of the video data. In other words, the data analysis unit 104 specifies that there are two pieces of video data to be output, and the Vista size video data has been changed to the standard size video data. That is, there are two types of video data to be output: standard size video data α and video data β.

  In step S303, the display area determination unit 105 then combines the display areas of the video data α and the video data β based on the specification information, the arrangement information, the selection criteria, the number of video data, and the aspect ratio. To decide. FIG. 11 shows an example of a combination that the display area determination unit 105 has selected based on the specification information, the arrangement information, the number of video data, and the aspect ratio. FIG. 11 is a diagram (part 3) illustrating an example of a combination. FIG. 12 is a diagram illustrating an example in which the video data α and the video data β are displayed on the multi-display with the combination Index1 and Index2.

That is, there are two combinations shown in FIG. 11 for outputting two standard-size video data.
The display area determination unit 105 determines one combination according to the selection criterion selected by the combination criterion setting unit 107 in step S202. In step S <b> 202, the combination criterion setting unit 107 selects the selection criterion “combination in which the size of each video data is close while maintaining the aspect ratio”. Therefore, the display area determination unit 105 selects Index1 that best meets the selection criteria from the combinations shown in FIG. That is, the display area determination unit 105 sets the display area of the video data α to No. 1 of Index 1 in FIG. 1 and the display area of the video data β is No. 1. 2.

  In step 304, the data display unit 106 acquires the display location of the video data α and the video data β from the display area determination unit 105. Then, the data display unit 106 displays No. 1 of Index 1 in FIG. 1, no. A display command is issued to the multi-display through the display device input / output unit 108 so that the video data α and β are respectively displayed at the position 2. The display device input / output unit 108 receives the command of the data display unit 106 and outputs video data to each display device 109 of the multi-display.

That is, the video data β displayed using the 6 screens of the display device 109 is changed so that the horizontal size is slightly shortened and displayed on the 4 screens by becoming the standard size.
Therefore, even if there are a plurality of video data, the video data can be efficiently arranged on the multi-display system, and the user can view the video in an easily viewable size.
