obtaining a plurality of videos by taking an identical scene from a plurality of different viewpoints over a plurality of successive periods;

selecting a plurality of first selected videos respectively selected for each of the plurality of periods, each of the plurality of first selected videos being selected from among the plurality of videos for each of the plurality of periods in accordance with rating values of the plurality of videos, the rating values being given by a plurality of users; and

transmitting from a server to a terminal device, a first video signal for successively replaying the plurality of first selected videos.

2. The method according to claim 1, wherein

each of the rating values is a rating value of each of the plurality of videos, and

in the selecting, selecting each of the plurality of first selected videos having a highest rating value or having a rating value higher than a predetermined value in the period.

3. The method according to claim 1, wherein

each of the rating values is a rating value of each of a plurality of subjects included in the plurality of videos, and

in the selecting, selecting each of the plurality of first selected videos in which a recommended subject having a highest rating value or having a rating value higher than a predetermined value is visible.

4. The method according to claim 3, wherein

in the selecting, selecting each of the plurality of first selected videos in which the recommended subject has a largest area.

5. The method according to claim 1, further comprising:

in a case where the first video signal has an amount of data larger than an upper limit based on a reception band of the terminal device,

selecting a plurality of second selected videos respectively selected for the plurality of periods, each of the plurality of second selected videos being selected from among the plurality of videos for each of the plurality of periods in accordance with the rating values of the plurality of videos; and

transmitting to the terminal device a second video signal for successively replaying the plurality of second selected videos, wherein

at least one of the plurality of second selected videos respectively selected for the plurality of periods is different from the plurality of first selected videos respectively selected for the plurality of periods, and

the second video signal has an amount of data smaller than the upper limit.

6. The method according to claim 1, wherein

the plurality of videos are transmitted from a plurality of cameras to the server in real time, and

in a case where transmission of a video corresponding to one of the plurality of first selected videos from a corresponding one of the cameras is discontinued,

in the selecting of the plurality of first selected videos, a second selected video different from the one of the plurality of first selected videos is selected, and

in the transmitting of the first video signal, a second video signal for replaying the second selected video is transmitted to the terminal device.

7. The method according to claim 1, wherein

each of the rating values is a rating value of each of the plurality of videos, and

in the selecting, selecting each of the plurality of first selected videos having a rating value lower than a predetermined value in the period.

8. The method according to claim 1, wherein

in the transmitting of the first video signal, the first video signal that is generated by connecting together the plurality of first selected videos is transmitted to the terminal device.

9. The method according to claim 1, wherein

in the transmitting of the first video signal, the plurality of first selected videos and information for identifying the plurality of first selected videos are transmitted to the terminal device as the first video signal.

10. A method comprising:

receiving from a server a video signal for successively replaying a plurality of videos respectively selected for each of a plurality of periods from among a plurality of videos in accordance with rating values of the plurality of videos, the rating values being given by a plurality of users, the plurality of videos being obtained by taking an identical scene from a plurality of different viewpoints over a plurality of successive periods; and

successively replaying the plurality of selected videos in accordance with the video signal.

11. The method according to claim 10, wherein

each of the rating values is a rating value of each of the plurality of videos, and

each of the selected videos is a video that is selected from among the plurality of videos for each period among the plurality of periods and that has a highest rating value or a rating value higher than a predetermined value in the period.

12. The method according to claim 10, wherein

each of the rating values is a rating value of each of a plurality of subjects included in the plurality of videos, and

each of the selected videos is a video which is selected from among the plurality of videos for each of the plurality of periods and in which a subject having a highest rating value or having a rating value higher than a predetermined value is visible.

13. The method according to claim 10, further comprising:
