This explains the case where the type of switch video is "tap". The user terminal 3 is configured to press and hold the main display area 571 while displaying the first video (A) on the main display area 571 (continuing to touch the touch panel or press down the mouse button for a predetermined period of time). .)
Then, the second moving image (B) is displayed in the main display area 572. On the other hand, if the main display area 571 is briefly tapped (touching the touch panel for less than a predetermined time or continuing to press down the mouse button) while the first video (A) is displayed in the main display area 571, the audio settings A setting screen 573 such as the following can be displayed.

Although the present embodiment has been described above, the above embodiment is for facilitating understanding of the present invention, and is not for construing the present invention in a limited manner. The present invention may be modified and improved without departing from the spirit thereof, and the present invention also includes equivalents thereof.

For example, in this embodiment, the video server 1, the content creator terminal 2, and the user terminal 3 are each one computer, but each can be realized by a plurality of computers. For example, the functional units and storage units can be distributed and provided in a plurality of computers.

Furthermore, in this embodiment, when the switch type is "tap", switching is performed each time the main display area is pressed (selected by clicking, tapping, etc.); Alternatively, the second video may be switched only while the mouse button is being touched (mouse down) or the touch panel is being touched, and the video may be switched to the first video only when the mouse button is released (mouse up) or the touch panel is no longer touched.

Further, in this embodiment, two videos are switched, but the present invention is not limited to this, and three or more videos may be switched. In this case, when the switch type is "wipe", the number of sub-display areas is set equal to the number of videos minus one, and when the switch type is "tap", multiple videos are sequentially switched each time the switch type is "tap". Do it like this.
