Is notified to the acquisition unit 21.

Further, when the display control unit 22 receives the divided file from the acquisition unit 21, the display control unit 22 displays the moving image corresponding to the thumbnail image selected from the playlist list 63L for the left moving image as the left moving image 62L in the moving image reproduction area 61. Further, the moving image corresponding to the thumbnail image selected from the playlist list 63R for the right moving image is displayed as the right moving image 62R in the moving image reproduction area 61.

Here, in the general method of streaming playback of a moving image by HTML (HyperText Markup Language), the position and size of the area where the moving image is played back are fixed in advance. In the present embodiment, each of the left moving image 62L and the right moving image 62R is provided with control information of the display size and the display position, and the display control unit 22 uses this control information to each of the left moving image 62L and the right moving image 62R. Is arranged at an arbitrary position in the moving image reproduction area 61 in an arbitrary size. The display size, which is the control information, is information that specifies, for example, the width and height of each of the left moving image 62L and the right moving image 62R. The display position, which is the control information, is information that specifies the x-coordinate and the y-coordinate of any one point (for example, the upper left corner) of each of the left moving image 62L and the right moving image 62R. The x-coordinate and y-coordinate use the coordinate values when a coordinate system is set in which the upper left corner of the moving image reproduction area 61 is the origin, the right direction is the plus direction of the x-axis, and the downward direction is the plus direction of the y-axis. be able to.

Further, the display control unit 22 has an operation button group 64L for the left moving image for controlling the reproduction of the left moving image 62L and a right moving image for controlling the reproduction of the right moving image 62R in a predetermined area of the moving image reproduction screen 60. The operation button group 64R of is displayed. Further, the display control unit 22 displays a common operation button group 64C for simultaneously controlling the reproduction of the left moving image 62L and the reproduction of the right moving image 62R. Each of the operation button groups 64L, 64C, 64R includes, for example, a fast-rewind button, a play button, a pause button, a fast-forward button, a frame-back button, a slow-play button, a frame-forward button, and the like as operation buttons.

When the operation button of the operation button group 64L for the left moving image is operated by the user, the display control unit 22 controls the reproduction of the left moving image 62L based on the operated button and the operation amount. Further, when the operation button of the operation button group 64R for the right moving image is operated by the user, the display control unit 22 controls the reproduction of the right moving image 62R based on the operated button and the operation amount. Further, when the operation button of the common operation button group 64C is operated by the user, the display control unit 22 controls the reproduction of both the left moving image 62L and the right moving image 62R based on the operated button and the operation amount. do. As a result, not only the reproduction of each of the left moving image 62L and the right moving image 62R can be controlled, but also the reproduction of both moving images 62L and 62R can be performed in synchronization with each other. For example, the left moving image 62L is paused at a desired timing, and the frame image of the right moving image 62R whose timing is desired to be matched with the paused frame image is searched for and displayed by frame advance, etc., and the common operation button group 64C Select the play button for. This makes it possible to realize synchronous reproduction in which the reproduction timings of desired frame images are matched.

Further, the display control unit 22 displays the horizontal bar display button 65 in a predetermined area of the moving image reproduction screen 60. The horizontal bar is a mark for designating the position in the height direction for each of the left moving image 62L and the right moving image 62R. When the horizontal bar display button 65 is selected, the display control unit 22 displays the horizontal bar 66L for the left video on the left video 62L and the horizontal bar 66L for the right video on the right video 62R, for example, as shown in FIG. Displays the horizontal bar 66R of. The positions of the horizontal bars 66L and 66R displayed when the horizontal bar display button 65 is selected are the predetermined initial positions (for example, the positions of each height 1/2 of the left moving image 62L and the right moving image 62R). can do.

Further, the display control unit 22 displays the horizontal bar position adjustment button 67L for the left moving image and the horizontal bar position adjusting button 67R for the right moving image in a predetermined area of the moving image reproduction screen 60. The horizontal bar position adjusting buttons 67L and 67R are buttons for instructing the change in the height of the horizontal bars 66L and 66R. For example, the display control unit 22 sets the display position of each horizontal bar 66L, 66R to a predetermined pixel (for example, every time the button indicating the upward or downward direction of each horizontal bar position adjustment button 67L, 67R is selected once. Move it upward or downward by 1 pixel). The horizontal bars 66L and 66R may be directly movable in the vertical direction by dragging or swiping.

Further, the display control unit 22 displays the height adjustment execution button 68 in the predetermined area of the moving image reproduction screen 60 instead of the horizontal bar display button 65. When the height adjustment execution button 68 is selected, the display control unit 22 sets the positions in the moving images 62L and 62R indicated by the horizontal bars 66L and 66R to the same height as shown in FIG. , Adjust the display position of at least one of the left moving image 62L and the right moving image 62R. In FIG. 4, the positions where the horizontal bar 66L for the left moving image and the horizontal bar 66R for the right moving image are displayed are indicated by the dotted line P.

Specifically, the display control unit 22 has the difference between the height of the horizontal bar 66L for the left moving image and the height of the horizontal bar 66R for the right moving image, the current display positions of the left moving image 62L and the right moving image 62R, and the display position. Acquires information on the size of the moving image playback area 61. The display control unit 22 obtains a display position in which at least one of the left moving image 62L and the right moving image 62R is adjusted based on the acquired information. For example, the display control unit 22 raises the horizontal bars 66L and 66R to a position where the movement amount is the difference between the heights of the horizontal bars 66L and 66R within the range where the left moving image 62L does not protrude from the moving image reproduction area 61. Find the display position when moving in the direction in which they match. If the amount of movement is less than the difference, the heights of the horizontal bars 66L and 66R match the right moving image 62R up to the position where the amount of movement is the rest of the difference within the range that does not protrude from the moving image playback area 61. Find the display position when moving in the direction. The display control unit 22 updates the display position information included in the control information of each of the left moving image 62L and the right moving image 62R to the display position obtained as described above. Then, the display control unit 22 changes the display position of at least one of the left moving image 62L and the right moving image 62R based on the updated control information.

If the amount of movement is less than the difference even if both moving images 62L and 62R are moved to the limit within the range not protruding from the moving image playback area 61, the display size of both moving images 62L and 62R is reduced and then the display size is reduced. The height of the display position may be adjusted.

As described above, in the present embodiment, each of the left moving image 62L and the right moving image 62R can be arranged in an arbitrary area with an arbitrary size by the control information of each of the left moving image 62L and the right moving image 62R. Thereby, the display positions of the left moving image 62L and the right moving image 62R can be adjusted based on the designated positions (positions in the moving images 62L and 62R indicated by the horizontal bars 66L and 66R). Such adjustment of the display position of the moving image can be realized by a combination of work frames that can realize detailed functions, instead of a large framework work frame that can be easily handled like a media player. For example, the above function can be realized by a combination of a work frame for displaying a moving image, a work frame for displaying a line, a work frame for detecting an operation such as touch, and the like. As the work frame for displaying the moving image, for example, the layers of AVFoundation's AVPlayer and AVPlayerItem, which are audio-related work frames in iOS (registered trademark), can be used.

The moving image playback device 20 can be realized by, for example, the computer 40 shown in FIG. The computer 40 includes a CPU 41, a memory 42 as a temporary storage area, and a non-volatile storage unit 43. Further, the computer 40 includes an input / output interface (I / F) 44 to which an input / output device 48 such as a display device and an input device is connected. Further, the computer 40 includes a read / write (R / W) unit 45 that controls reading and writing of data to the recording medium 49, and a network I / F 46 connected to a network such as the Internet. The CPU 41, the memory 42, the storage unit 43, the input / output I / F 44, the R / W unit 45, and the network I / F 46 are connected to each other via the bus 47.

The storage unit 43 can be realized by an HDD (Hard Disk Drive), an SSD (solid state drive), a flash memory, or the like. In the storage unit 43 as a storage medium, a moving image reproduction program 50 for making the computer 40 function as the moving image reproducing device 20 is stored. The moving image reproduction program 50 includes an acquisition process 51 and a display control process 52.

The CPU 41 reads the moving image reproduction program 50 from the storage unit 43, expands it into the memory 42, and sequentially executes the processes included in the moving image reproduction program 50. The CPU 41 operates as the acquisition unit 21 shown in FIG. 1 by executing the acquisition process 51. Further, the CPU 41 operates as the display control unit 22 shown in FIG. 1 by executing the display control process 52. As a result, the computer 40 that has executed the moving image reproduction program 50 functions as the moving image reproducing device 20.

The function realized by the moving image reproduction program 50 can also be realized by, for example, a semiconductor integrated circuit, more specifically, an ASIC (Application Specific Integrated Circuit) or the like.

Next, the operation of the moving image reproduction system 10 according to the first embodiment will be described.

When the user logs in to the video playback application in the video playback device 20, the acquisition unit 21 transmits the logged-in user's identification information (for example, the user name) to the video management device 30.

When the video management device 30 receives the user's identification information, the control unit 31 transmits a playlist list of video data that is permitted to be distributed to the logged-in user to the video playback device 20.

In the moving image playback device 20, the acquisition unit 21 passes the acquired playlist list to the display control unit 22. The display control unit 22 displays, for example, a moving image reproduction screen 60 (the left moving image 62L and the right moving image 62R are not displayed) as shown in FIG.

When a thumbnail image is selected from each of the playlist list 63L for the left moving image and the playlist list 63R for the right moving image by the user, the display control unit 22 highlights the selected thumbnail image. Then, the display control unit 22 has a playlist name corresponding to the thumbnail image selected from the playlist list 63L for the left video and a playlist name corresponding to the thumbnail image selected from the playlist list 63R for the right video. Is notified to the acquisition unit 21. Then, the acquisition unit 21 requests the moving image data from the moving image management device 30 by transmitting the playlist name indicating each of the notified left moving image 62L and the right moving image 62R to the moving image management device 30.

In the moving image management device 30, the control unit 31 acquires a playlist corresponding to the requested moving image data from the moving image DB 32 and transmits the playlist to the moving image reproducing device 20.

In the moving image playback device 20, the acquisition unit 21 acquires a playlist and requests the moving image management device 30 to sequentially divide files according to the acquired playlist.

In the moving image management device 30, the control unit 31 acquires the requested divided file from the moving image DB 32 and sequentially transmits the requested divided file to the moving image reproducing device 20.

In the moving image playback device 20, the acquisition unit 21 sequentially delivers the acquired divided files to the display control unit 22. Then, when the display control unit 22 receives the divided file from the acquisition unit 21, the display control unit 22 reproduces each of the left moving image 62L and the right moving image 62R in the moving image reproduction area 61. The display size and display position of each of the left moving image 62L and the right moving image 62R are determined by the control information of each of the left moving image 62L and the right moving image 62R. At this stage, it is assumed that a predetermined initial value is set in the control information. Then, the display control unit 22 controls the reproduction of each of the left moving image 62L and the right moving image 62R based on the user's operation on the operation buttons of each operation button group 64L, 64C, 64R.

Then, when the horizontal bar display button 65 is selected by the user while the video playback screen 60 including the horizontal bar display button 65 is displayed, the height adjustment process shown in FIG. 6 is executed in the video playback device 20. Will be done.

In step S11 of the height adjustment process shown in FIG. 6, the display control unit 22 displays, for example, a horizontal bar 66L for the left moving image at a predetermined initial position on the left moving image 62L as shown in FIG. The horizontal bar 66R for the right moving image is displayed at a predetermined initial position on the right moving image 62R.

Next, in step S12, the display control unit 22 determines whether or not the height adjustment execution button 68 has been selected by the user. If the height adjustment execution button 68 is not selected, the process proceeds to step S13.

In step S13, it is determined whether or not the display control unit 22 has accepted the change of the position of either the horizontal bar 66L for the left moving image or the horizontal bar 66R for the right moving image. For example, when any of the horizontal bar position adjustment buttons 67L and 67R is selected, or when any of the horizontal bars 66L and 66R is dragged or swiped, the display control unit 22 displays the horizontal bars 66L and 66R. Accepts changes in any of the positions. Then, the process proceeds to step S14. On the other hand, if the position change is not accepted, the process returns to step S12.

In step S14, the display control unit 22 changes the display positions of the horizontal bars 66L and 66R so that the horizontal bars 66L and 66R are displayed at the positions accepted in step S13, and the process returns to step S12.

When the display control unit 22 determines in step S12 that the height adjustment execution button 68 has been selected by the user, the process proceeds to step S15. In step S15, for example, as shown in FIG. 4, the display control unit 22 has the left moving image 62L so that the positions in the moving images 62L and 62R indicated by the horizontal bars 66L and the horizontal bars 66R are at the same height. And adjust the display position of at least one of the right moving image 62R. Then, the height adjustment process is completed.

As described above, according to the video playback system 10 according to the first embodiment, the video playback device 20 sets the display positions of the left video and the right video to the same positions in the vertical direction at the positions specified by the horizontal bars. Adjust so that they are lined up, that is, the heights of the specified positions are the same. This facilitates comparison between the left video and the right video.

In the first embodiment, the case of adjusting the height of the display position of the left moving image 62L and the right moving image 62R arranged side by side in the horizontal direction has been described, but the present invention is not limited to this. For example, as shown in FIG. 7, on the moving image reproduction screen 160, the horizontal display positions of the upper moving image 62U and the lower moving image 62D arranged side by side in the vertical direction may be adjusted. In the moving image reproduction screen 160, for the same configuration as each configuration of the moving image reproduction screen 60 in FIG. 3, a similar reference numeral in which only the end of the reference numeral is changed from “L” or “R” to “U” or “D” is used. A detailed description will be omitted. The reference numeral "U" is attached to the configuration related to the upper moving image 62U, and the reference numeral "D" is attached to the configuration related to the lower moving image 62D.

Specifically, when the vertical bar display button 165 provided on the moving image playback screen 160 (see also FIG. 8) is selected, the display control unit 22 displays the vertical bar 66U for the upper moving image on the upper moving image 62U. , The vertical bar 66D for the lower moving image is displayed on the lower moving image 62D. Like the horizontal bars 66L and 66R, the vertical bars 66U and 66D can be moved in the horizontal direction by operating the vertical bar position adjustment button 67U for the upper moving image and the vertical bar position adjusting button 67D for the lower moving image. be. It is also possible to move the vertical bars 66U and 66D directly in the horizontal direction by dragging or swiping. Then, when the horizontal position adjustment execution button 168 provided on the moving image reproduction screen 160 is selected, the display control unit 22 in the moving images 62L and 62R shown by the vertical bars 66U and 66D, respectively, as shown in FIG. The display position of at least one of the upper moving image 62U and the lower moving image 62D is adjusted so that the positions are the same in the horizontal direction. In FIG. 8, the positions where the vertical bar 66U for the upper moving image and the vertical bar 66D for the lower moving image are displayed are indicated by the dotted line Q.

As a result, the horizontal display positions of the upper moving image 62U and the lower moving image 62D can be adjusted in the same manner as in the case of adjusting the vertical display positions of the left moving image 62L and the right moving image 62R.

<Second Embodiment>
Next, the moving image reproduction system according to the second embodiment will be described. In the moving image reproduction system according to the second embodiment, the same parts as those of the moving image reproduction system 10 according to the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 1, the video reproduction system 210 according to the second embodiment includes a video reproduction device 220 and a video management device 30. The video playback device 220 and the video management device 30 are connected to each other via a network. As shown in FIG. 1, the moving image reproduction device 220 functionally includes an acquisition unit 21 and a display control unit 222. The display control unit 222 is an example of the reception unit and the adjustment unit of the present invention.

The moving image reproduction screen 260 includes a superimposing mark display button 265 instead of the horizontal bar display button 65 of the moving image reproduction screen 60 in the first embodiment. The superimposition mark is a mark for designating a position that serves as a reference for superimposition when the left moving image 62L and the right moving image 62R are superimposed and displayed. When the superimposed mark display button 265 is selected, the display control unit 222 displays the superimposed mark 266L for the left moving image on the left moving image 62L and for the right moving image on the right moving image 62R, for example, as shown in FIG. The superimposition mark 266R of is displayed. In the example of FIG. 10, the quadrangle and the marks represented by the diagonal lines in the quadrangle are the superimposed marks 266L and 266R, and the positions (coordinates) of the superimposed marks 266L and 266R are specified by the positions of the intersections of the diagonal lines. The position of each superimposed mark 266L, 266R displayed when the superimposed mark display button 265 is selected can be a predetermined initial position (for example, the center of each of the left moving image 62L and the right moving image 62R).

Further, the display control unit 222 displays the superimposed mark position adjustment button 267L for the left moving image and the superimposed mark position adjusting button 267R for the right moving image in a predetermined area of the moving image reproduction screen 260. Each superimposition mark position adjustment button 267L and 267R is a button for instructing the change of each position of each superimposition mark 266L and 266R in the horizontal direction and the vertical direction. For example, the display control unit 222 sets the display position of each superimposition mark 266L and 266R to a predetermined pixel each time the button indicating one of the up, down, left, and right directions of each superimposition mark position adjustment button 267L and 267R is selected once. For example, it is moved in a specified direction by 1 pixel). The superimposed marks 266L and 266R may be directly movable in the vertical and horizontal directions by dragging or swiping.

Further, the display control unit 222 displays the superimposition execution button 268 in place of the superimposition mark display button 265 in a predetermined area of the moving image reproduction screen 260. When the superimposition execution button 268 is selected, the display control unit 222 sets the positions in the moving images 62L and 62R indicated by the superimposing mark 266L for the left moving image and the superimposing mark 266R for the right moving image as shown in FIG. The display position of at least one of the left moving image 62L and the right moving image 62R is adjusted so that the positions are the same. In the example of FIG. 11, the right moving image 62R is arranged in the center of the moving image reproduction area 61, and the left moving image 62L with the transparency setting is superimposed on the right moving image 62R. The dotted line S in FIG. 11 indicates the position where the superimposed mark 266L or the superimposed mark 266R is displayed on the left moving image 62L or the right moving image 62R. Information on the order of superimposition (which moving image is overlaid on top) and the transparency setting can be provided as control information for each of the moving images 62L and 62R.

The display control unit 222 acquires information on the positions of the superimposed marks 266L and 266R on each moving image, the current display positions of the left moving image 62L and the right moving image 62R, and the size of the moving image reproduction area 61. The display control unit 222 obtains a display position in which at least one of the left moving image 62L and the right moving image 62R is adjusted based on the acquired information. For example, the display control unit 222 obtains the position of the superimposed mark 266R for the right moving image when the right moving image 62R is arranged in the center of the moving image reproduction area 61. Then, the display control unit 222 obtains the horizontal and vertical differences between the obtained superimposition mark 266R position for the right moving image and the current superimposing mark 266L position for the left moving image, and moves the difference. Is obtained as the display position of the left moving image 62L. If any of the videos 62L and 62R protrudes from the video playback area 61, adjust so that they do not protrude, or reduce the display size of both videos 62L and 62R and then readjust the display position. May be good.

The display control unit 222 updates the display position information included in the control information of each of the left moving image 62L and the right moving image 62R to the display position obtained as described above. Further, the display control unit 222 sets the order of superposition in the control information of each of the moving images 62L and 62R. Further, the display control unit 222 sets a predetermined transmittance in the transparency setting included in the control information of the moving image on the overlay side. Then, the display control unit 222 changes the display position of at least one of the left moving image 62L and the right moving image 62R based on the updated control information, and superimposes and displays the left moving image 62L and the right moving image 62R.

Further, the display control unit 222 displays the superimposed display position adjustment button 69 in a predetermined area of the moving image reproduction screen 260. The superimposed display position adjustment button 69 is a button for instructing adjustment of at least one of the left moving image 62L and the right moving image 62R that are superimposed and displayed. Depending on the size of the display unit and the content of the video, it may be easier to compare both videos 62L and 62R by slightly shifting them than when superimposing the marks 266L and 266R so that they match perfectly. It is possible to adjust the superimposed display position. In the example of FIG. 11, a superimposed display position adjusting button 69 for adjusting the display position of the left moving image 62L superimposed on the top is provided. In this case, each time the button indicating either the up, down, left, or right direction of the superimposed display position adjustment button 69 is selected, the display control unit 222 displays the display position of the left moving image 62L, for example, as shown in FIG. Is moved in a designated direction by a predetermined pixel (for example, one pixel).

Further, the display control unit 222 displays the superimposition display release button 70 in place of the superimposition execution button 268 in a predetermined area of the moving image reproduction screen 260. When the superimposed display release button 70 is selected, the display control unit 222 returns the moving image reproduction screen 260 to the state before the superimposed display is executed (for example, the moving image reproduction screen 260 shown in FIG. 9).

The moving image reproduction device 220 can be realized by, for example, the computer 40 shown in FIG. In the storage unit 43 of the computer 40, a moving image reproduction program 250 for making the computer 40 function as the moving image reproducing device 220 is stored. The moving image reproduction program 250 has an acquisition process 51 and a display control process 252.

The CPU 41 reads the moving image reproduction program 250 from the storage unit 43, expands it into the memory 42, and sequentially executes the process of the moving image reproduction program 250. The CPU 41 operates as the acquisition unit 21 shown in FIG. 1 by executing the acquisition process 51. Further, the CPU 41 operates as the display control unit 222 shown in FIG. 1 by executing the display control process 252. As a result, the computer 40 that has executed the moving image reproduction program 250 functions as the moving image reproducing device 220.

The function realized by the moving image reproduction program 250 can also be realized by, for example, a semiconductor integrated circuit, more specifically, an ASIC or the like.

Next, the operation of the moving image reproduction system 210 according to the second embodiment will be described. The second embodiment is different in that the superimposed display process shown in FIG. 13 is executed instead of the height adjustment process (FIG. 6) executed in the first embodiment. The superimposed display process is executed in the moving image reproduction device 220 when the superimposed mark display button 265 is selected by the user while the moving image reproduction screen 260 including the superimposed mark display button 265 is displayed.

In step S21 of the superimposed display process shown in FIG. 13, the display control unit 222 displays the superimposed mark 266L for the left moving image at a predetermined initial position on the left moving image 62L, for example, as shown in FIG. Further, the display control unit 222 displays the superimposed mark 266R for the right moving image at a predetermined initial position on the right moving image 62R.

Next, in step S22, the display control unit 222 determines whether or not the superimposition execution button 268 has been selected by the user. If the superimposition execution button 268 is not selected, the process proceeds to step S23.

In step S23, it is determined whether or not the display control unit 222 has accepted the change of the position of either the superimposition mark 266L for the left moving image or the superimposing mark 266R for the right moving image. For example, when any of the superimposed mark position adjustment buttons 267L and 267R is selected, or when any of the superimposed marks 266L and 266R is dragged, the display control unit 22 displays any of the superimposed marks 266L and 266R. Accepts changes in that position. Then, the process proceeds to step S24. On the other hand, if the position change is not accepted, the process returns to step S22.

In step S24, the display control unit 222 changes the display position of the superimposition mark 266L and 266R so that the superimposition mark 266L and 266R are displayed at the position received in step S23, and the process returns to step S22.

When the display control unit 222 determines in step S22 that the superimposition execution button 268 has been selected by the user, the process proceeds to step S25. In step S25, for example, as shown in FIG. 11, the display control unit 22 transparently sets the left moving image 62L so that the overlapping mark 266L for the left moving image and the overlapping mark 266R for the right moving image are at the same position. , The left moving image 62L is superimposed and displayed on the right moving image 62R.

Next, in step S26, the display control unit 222 determines whether or not the change in the position of the superimposed display has been accepted. For example, when the superimposed display position adjustment button 69 is selected, the display control unit 222 accepts the change of the superimposed display position, and the process proceeds to step S27. On the other hand, if the position change is not accepted, the process returns to step S26.

In step S27, the display control unit 222 changes the display position of at least one of the left moving image 62L and the right moving image 62R based on the position received in step S26, and the process returns to step S26.

If the display control unit 222 determines in step S26 that the change in the position of the superimposed display is not accepted, the process proceeds to step S28, and the display control unit 222 selects the superimposed display release button 70 by the user. Determine if it has been done. If the superimposed display button 70 is not selected, the process returns to step S26. When the superimposed display button 70 is selected, the superimposed display of the left moving image 62L and the right moving image 62R is canceled, and the superimposed display process is terminated.

As described above, according to the video playback system 210 according to the second embodiment, the video playback device 220 sets the display positions of the left video and the right video, and the positions designated by the superimposition marks are in the horizontal direction and the vertical direction. Adjust so that they line up in the same position. That is, the left moving image and the right moving image are superimposed and displayed based on the position of the superimposed mark. This facilitates comparison between the left video and the right video.

Further, by making it possible to adjust the superimposed display position of the left moving image and the right moving image that are superimposed and displayed based on the position of the overlapping mark, it becomes easier to compare the left moving image and the right moving image.

In the second embodiment, the case where the left moving image set to be transparent is superimposed on the right moving image has been described, but the present invention is not limited to this. The right video may be on top, or both videos may be set to be transparent.

Further, in the second embodiment, the case where the display position of the superimposed display moving image is shifted in the horizontal direction or the vertical direction by the operation of the superimposed display position adjustment button has been described, but the present invention is not limited to this. For example, when executing superimposed display, it is set in advance so that the superimposed display of both moving images is superimposed and displayed at a position shifted by a predetermined distance in the horizontal or vertical direction from the position where the superimposed marks are completely matched. You may.

In addition, it is not limited to the case of superimposing with the superimposition mark as a reference, and by moving one video directly to at least one of the horizontal direction and the vertical direction by a button operation or a drag operation, and superimposing it on the other video. The superimposed display of both moving images may be realized.

<Third Embodiment>
Next, the moving image reproduction system according to the third embodiment will be described. In the third embodiment, a case where the display position of the moving image is shared between the users will be described. In the moving image reproduction system according to the third embodiment, the same parts as those of the moving image reproduction system 10 according to the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 1, the video reproduction system 310 according to the third embodiment includes a video reproduction device 320 and a video management device 330. The video playback device 320 and the video management device 330 are connected to each other via a network.

The control unit 331 of the video management device 330 controls the distribution of video data to the video playback device 320, similarly to the control unit 31 in the first embodiment. In addition, the control unit 331 manages the shared information for sharing the display position of the moving image between the users. Although the details will be described later, the shared information includes a user name, two playlist names, and information on the display position of the moving image indicated by each playlist. In the following, the user who registers the shared information in the video management device 330 is also referred to as the "sender user", and the user who plays the video using the shared information managed by the video management device 330 is "received". Also called "side user".

Specifically, the control unit 331 receives the shared information transmitted from the moving image reproducing device 320 according to the instruction of the transmitting side user. The control unit 331 holds, for example, the shared information table 332A as shown in FIG. 14 in the moving image DB 332 storing the plurality of moving image data and the playlist of each moving image data, and manages the received shared information. In the example of FIG. 14, each row corresponds to one shared information. Further, "playlist 1" and "playlist 2" are each of the two playlist names included in the shared information. Also in the third embodiment, similarly to the first embodiment, in the moving image reproduction device 320, the moving image is reproduced in a state where the left moving image 62L and the right moving image 62R are arranged side by side. Therefore, each of the two playlist names is the playlist name of the left moving image 62L and the playlist name of the right moving image 62R. However, since both moving images 62L and 62R can distinguish between the left moving image 62L and the right moving image 62R based on the display position, playlist 1 or playlist 2 corresponds to either the left moving image 62L or the right moving image 62R. There is no need to specify whether to do it.

Further, the control unit 331 manages the shared information for each transmitting user. Therefore, when the shared information is registered in the shared information table 332A, the control unit 331 assigns a number for identifying the shared information for each user name to each shared information as a “user-specific shared information number”.

Further, as shown in FIG. 15, the video DB 332 corresponds to the shared information transmitted by the user as the transmitting user with the identification information (for example, the user name) of the user who can be used as the receiving user, as shown in FIG. The attached shared user table 332B is also stored. The shared user table 332B may be registered in advance at the time of registration of use of the application, or the shared information includes the user name of the user who can use the shared information and is registered when the control unit 331 receives the shared information. You may.

The control unit 331 transmits a playlist list of video data that is permitted to be distributed to the logged-in user, and if there is shared information available to the logged-in user, the control unit 331 notifies the video playback device 320 to that effect. do. Specifically, the control unit 331 refers to the shared user table 332B, searches for the user name of the logged-in user from the "receiving side user" column, and acquires the user name of the corresponding transmitting side user. Then, when the shared information managed in association with the acquired user name exists in the shared information table 332A, the control unit 331 determines that the shared information that can be used by the logged-in user exists.

Further, when the control unit 331 receives the request for the shared list (details will be described later) from the video playback device 320, the control unit 331 acquires the shared information available to the logged-in user from the shared information table 332A, and lists the acquired shared information. The converted shared list is transmitted to the moving image playback device 320. The shared list includes at least the user name of each shared information and the shared information number for each user. Further, in addition to the information included in the shared information, meta information, thumbnail images, and the like of the moving image data indicated by the playlist name included in each shared information may be included.

Further, when the control unit 331 receives the request for the shared video from the video playback device 320, the shared information about the requested video and each of the two playlist names included in the shared information are assigned. The two playlists shown are acquired from the moving image DB 332. Then, the control unit 331 transmits the acquired shared information and the playlist to the moving image playback device 320.

As shown in FIG. 1, the moving image reproducing device 320 functionally includes an acquisition unit 321 and a display control unit 322. The display control unit 322 is an example of the reception unit and the adjustment unit of the present invention.

The acquisition unit 321 acquires video data from the video management device 330 in the same manner as the acquisition unit 21 of the first embodiment. In addition, the acquisition unit 321 transmits the shared information to the moving image management device 330 according to the instruction of the transmitting side user.

Further, the acquisition unit 321 acquires the video data shared from the video management device 330 according to the instruction of the receiving side user. Specifically, when the acquisition unit 321 receives a notification from the video management device 330 that the shared information available to the logged-in user exists when the user logs in, the acquisition unit 321 displays the notification to that effect. Notify 322. Further, when the display control unit 322 notifies the acquisition unit 321 that the shared list display button has been selected (details will be described later), the acquisition unit 321 requests the video management device 330 for the shared list. Further, the acquisition unit 321 passes the shared list received in response to the request to the display control unit 322. Further, when the display control unit 322 notifies the user name and the user-specific shared information number of the shared information selected from the shared list (details will be described later), the acquisition unit 321 notifies the user name and the user-specific shared information number. Request a shared video by transmitting to the video management device 330. Then, the acquisition unit 321 acquires the shared information and the playlist received in response to the request, sequentially acquires the divided files from the video management device 330 according to the playlist, and displays the acquired divided files together with the shared information in the display control unit 322. Hand over to.

Similar to the display control unit 322 of the first embodiment, the display control unit 322 displays the moving image reproduction screen on the display unit and adjusts the height of the left moving image 62L and the right moving image 62R. In addition, the display control unit 322 displays the share button 71 on the moving image reproduction screen 360 in which the heights of the left moving image 62L and the right moving image 62R are adjusted, for example, as shown in FIG. When the share button 71 is selected, the display control unit 322 acquires the playlist names of the left moving image 62L and the right moving image 62R being played from the playlist list, and obtains the display position information of the moving images 62L and 62R, respectively. Obtained from the control information held by. The display control unit 322 adds the login user identification information (for example, the user name) to the playlist names and display position information of each of the acquired left video 62L and right video 62R, and acquires this as shared information. Hand over to unit 321.

Further, when the display control unit 322 is notified by the acquisition unit 321 that the shared information available to the logged-in user exists, the shared list display button 72 is displayed on the moving image playback screen 360 as shown in FIG. Is displayed. When the shared list display button 72 is selected, the display control unit 322 notifies the acquisition unit 321 to that effect.

Further, when the display control unit 322 receives the shared list from the acquisition unit 321, the display control unit 322 displays the shared list screen 80 as shown in FIG. 18, for example. The shared list screen 80 may be switched from the moving image reproduction screen 360 and displayed, or may be superimposed and displayed on the moving image reproduction screen 360. In the example of FIG. 18, the shared list screen 80 includes a shared list 81 and a selection button 82. In the shared list 81, each row corresponds to one shared information, and each row is displayed in a selectable state. Further, each row of the shared list 81 is associated with at least the user name and the shared information number for each user, and when at least one row is selected from the shared list 81, the user name and the shared information for each user associated with the row are selected. The shared information specified by the number will be selected. In the example of FIG. 18, the items included in the shared list 81 show the case where the user name, the playlist 1, and the playlist 2 are used, but the items are not limited to this. When the shared list acquired from the video management device 330 includes meta information of video data indicated by each playlist name, thumbnail images, and the like, such information may be displayed together.

When the selection button 82 is selected with at least one row selected from the shared list 81, the display control unit 322 uses the user name and user-specific sharing associated with the row selected in the shared list 81. Notify the acquisition unit 321 of the information number. Further, the display control unit 332 closes the shared list screen 80 and returns the display to the moving image playback screen 360.

Further, when the display control unit 322 receives the shared information together with the divided file from the acquisition unit 321, the display control unit 322 sets the information of the display position included in the shared information in the control information of the moving image indicated by the divided file. Specifically, for example, when the shared information in the first row of the shared information table 332A shown in FIG. 14 is received, the display position is included in the moving image control information indicated by the divided file acquired according to the playlist 1. Set (x1, y1). Similarly, (x2, y2) is set at the display position included in the control information of the moving image indicated by the divided file acquired according to the playlist 2. Then, the display control unit 322 arranges the moving images 62L and 62R according to the control information, so that the moving image reproduction screen 360 when the transmitting side user selects the shared button 71 when the receiving side user reproduces the moving image. The video can be displayed at the same display position.

The moving image reproduction device 320 can be realized by, for example, the computer 40 shown in FIG. In the storage unit 43 of the computer 40, a moving image reproduction program 350 for making the computer 40 function as the moving image reproducing device 320 is stored. The moving image reproduction program 350 has an acquisition process 351 and a display control process 352.

The CPU 41 reads the moving image reproduction program 350 from the storage unit 43, expands it into the memory 42, and sequentially executes the processes included in the moving image reproduction program 350. The CPU 41 operates as the acquisition unit 321 shown in FIG. 1 by executing the acquisition process 351. Also, CP

The function realized by the moving image reproduction program 350 can also be realized by, for example, a semiconductor integrated circuit, more specifically, an ASIC or the like.

Next, the operation of the moving image reproduction system 310 according to the third embodiment will be described. The third embodiment is the same as the first embodiment except for the process of sharing the display position of the moving image between the users. Therefore, the process of sharing the display position of the moving image between the users will be described below.

First, after explaining the flow of processing exchanged between the video playback device 320A operated by the transmitting side user, the video management device 330, and the video playback device 320B operated by the receiving side user, each device The details of the processing to be executed will be described. The video playback device 320A and the video playback device 320B are distinguished for convenience in order to explain the difference in behavior between when the shared information is transmitted and when the shared information is used. It does not mean a difference.

FIG. 19 shows a sequence diagram showing a flow of processing exchanged between the moving image reproducing device 320A, the moving image management device 330, and the moving image reproducing device 320B. In the moving image playback device 320A, for example, the height adjusting process of the left moving image 62L and the right moving image 62R is executed (S10) in the same manner as in the height adjusting process (FIG. 6) in the first embodiment. In that state, when the share button 71 is selected from the video reproduction screen 360, the display control unit 322 creates the shared information (S30) and transmits it to the video management device 330 (S33). The video management device 330 manages the received shared information (S40).

Then, when the user logs in with the video playback device 320B, the user name of the logged-in user is transmitted from the video playback device 320B to the video management device 330 (S71). If the shared information available to the logged-in user exists, the video management device 330 notifies the video playback device 320B to that effect (S72). Upon receiving this notification, when the video playback device 320B requests the shared list (S63), the video management device 330 transmits the shared list (S54). Then, the shared moving image is requested from the moving image reproducing device 320B to the moving image management device 330 (S66). The video management device 330 transmits the shared information about the requested video and the playlist indicated by the playlist name included in the shared information to the video playback device 320B (S56).

The moving image playback device 320B analyzes the acquired shared information and extracts information on the user name, each playlist name, and the display position of the moving image indicated by each playlist. Further, the moving image playback device 320B sequentially requests the moving image management device 330 for the divided files according to the acquired playlist (S68). The video management device 330 sequentially transmits the divided files to the video playback device 320B according to the request (S73). The moving image playback device 320B arranges and plays back the moving image indicated by the acquired divided file at a position according to the display position of the playlist included in the shared information (S69).

Hereinafter, the processes executed by each of the video playback device 320A, the video management device 330, and the video playback device 320B will be described.

Next, in step S32, the display control unit 322 acquires information on the display positions of the moving images 62L and 62R from the control information of the left moving image 62L and the right moving image 62R. Next, in step S33, the display control unit 322 adds the login user identification information (for example, the user name) to the acquired two playlist names and display position information, and uses this as shared information in the acquisition unit 321. Hand over to. Then, the acquisition unit 321 transmits the shared information to the moving image management device 330, and the shared information transmission process ends.

Next, when the video management device 330 receives the shared information transmitted from the video playback device 320A, the shared information reception process shown in FIG. 21 is executed.

In step S41, the control unit 331 assigns a user-specific shared information number to the received shared information. Next, in step S42, the control unit 331 stores the shared information to which the user-specific shared information number is assigned in the shared information table 332A of the moving image DB 332, and the shared information reception process ends.

Further, when the video management device 330 accepts the user name transmitted from the video playback device 320B by logging in to the video playback device 320B, the video management device 330 performs the shared video transmission process shown in FIG. 22. Will be executed.

In step S51, the control unit 331 refers to the shared user table 332B and the shared information table 332A of the moving image DB 332, and determines whether or not the shared information available to the logged-in user exists. If there is shared information available to the logged-in user, the process proceeds to step S52 to notify the moving image playback device 320B that the shared information available to the logged-in user exists. On the other hand, if there is no shared information available to the logged-in user, the shared video transmission process ends.

Next, in step S53, it is determined whether or not the control unit 331 has accepted the request for the shared list from the moving image playback device 320B. When the request of the shared list is accepted, the process proceeds to step S54, and when it is not accepted, the determination of this step is repeated.

In step S54, the control unit 331 acquires the shared information available to the logged-in user from the shared information table 332A, and transmits the shared list listing the acquired shared information to the moving image playback device 320B.

Next, in step S55, the control unit 331 determines whether or not the request for the shared moving image has been received from the moving image reproducing device 320B. When the request for the shared moving image is accepted, the process proceeds to step S56, and when it is not accepted, the determination in this step is repeated.

In step S56, the control unit 331 acquires the shared information about the requested video and the two playlists indicated by each of the two playlist names included in the shared information from the video DB 332, and reproduces the video. It transmits to the device 320B.

Next, in step S57, the control unit 331 determines whether or not the request for the divided file has been received from the moving image playback device 320B. When the request for the divided file is accepted, the process proceeds to step S58, and when the request is not accepted, the determination in this step is repeated.

In step S58, the control unit 331 acquires the requested divided file from the moving image DB 332 and sequentially transmits it to the moving image reproducing device 320B, and the shared moving image transmission process ends.

On the other hand, when the video management device 330 notifies the video playback device 320B that the shared information available to the logged-in user exists, the video playback device 320B executes the shared video playback process shown in FIG. 23.

In this case, information (for example, a time stamp or a frame number) for specifying each frame image of the left moving image 62L and the right moving image 62R displayed at the timing when the sharing button 71 is selected is acquired, and this information is used. It should be included in the shared information. When the shared video is played back by the receiving user, the frame image of the left video 62L and the frame image of the right video 62R specified from the information such as the time stamp included in the shared information are displayed at the same timing. As described above, the reproduction timing of the left moving image 62L and the right moving image 62R may be controlled.

Further, in each of the above embodiments, a case where a divided file obtained by dividing one video data at predetermined time intervals is sequentially acquired and played according to a playlist, that is, a video data divided into a plurality of segments and managed is targeted. However, the case is not limited to this. For example, as in MPEG4, it is also possible to target moving image data in which each segment is managed as an individual file. In this case, the shared information may include the file name of each file instead of the playlist name.

Further, in each of the above embodiments, the case of comparing two moving images has been described as an example, but the present invention can also be applied when comparing three or more moving images.

Further, in each of the above embodiments, the case where the video of baseball is reproduced is shown in the drawing, but the target video may be a video of other sports such as tennis or golf, or other than sports. It may be a video of. The disclosed technique is particularly suitable for comparison of moving images in which similar scenes are shot, but in which a slight difference in angle or the like occurs. For example, in the case of a baseball video, many compositions are taken from behind the pitcher in the direction of the batter, but even if the composition is similar, the difference in the stadium, the difference in the standing position of the pitcher and the batter, etc. Can make subtle differences. Even when comparing videos with such differences, if the display position can be adjusted as in each of the above embodiments, small parts such as the position of a specific part of the pitcher or batter can be compared. Comparison is also easy.

Further, in the above description, the mode in which the moving image reproduction programs 50, 250, and 350 are stored (installed) in the storage unit 43 in advance has been described, but the present invention is not limited to this.
