Abstract

There is provided a video delivery method for a server that delivers to a terminal device a video signal based on a plurality of videos obtained by shooting an identical scene from a plurality of different viewpoints over a plurality of successive periods, the method including: selecting a selected video 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 to the terminal device the video signal for successively replaying a plurality of the selected videos respectively selected for the plurality of periods.

First claim

What is claimed is:

1. A method comprising:
obtaining a plurality of videos by taking a subject 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;
transmitting from a server to a terminal device, a first video signal for successively replaying the plurality of first selected videos; and
when 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, instead of the first video signal, 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,
the second video signal has an amount of data smaller than the upper limit, and
each of a plurality of viewpoints of the selected second videos is closer to the subject than each of a plurality of viewpoints of the selected first 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 for a respective 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 occupies a largest area within a display.

5. 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
when 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, the 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, the second video signal for replaying the second selected video is transmitted to the terminal device.

6. 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 for a respective period.

7. The method according to claim 1 , wherein
in the transmitting of the first video signal, the first video signal is generated by connecting together the plurality of first selected videos.

8. 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.

9. A method comprising:
receiving from a server a first video signal for successively replaying a plurality of first 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 first videos being obtained by taking a subject from a plurality of different viewpoints over a plurality of successive periods;
successively replaying the plurality of selected first videos in accordance with the first video signal; and
when 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, instead of the first video signal, 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,
the second video signal has an amount of data smaller than the upper limit, and
each of a plurality of viewpoints of the selected second videos is closer to the subject than each of a plurality of viewpoints of the selected first videos.

10. The method according to claim 9 , wherein
each of the rating values is a rating value of each of the plurality of videos, and
each of the selected first 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 for a respective period.

11. The method according to claim 9 , 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 first 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.

12. The method according to claim 9 , further comprising:
displaying any video among the plurality of videos, wherein
in the displaying of the video, a subject having a highest rating value or having a rating value higher than a predetermined value is highlighted and displayed among a plurality of subjects included in the displayed video.

13. The method according to claim 9 , further comprising:
displaying any video among the plurality of videos; and
displaying, when a subject is selected by a user from among a plurality of subjects included in the displayed video, a menu for rating the selected subject.

14. The method according to claim 9 , further comprising:
displaying any video among the plurality of videos; and
displaying, when a subject is selected by a user from among a plurality of subjects included in the displayed video, a list of videos for the plurality of periods among the plurality of videos, the videos in the list including the selected subject and having rating values higher than a predetermined value.

15. The method according to claim 9 , further comprising:
