Next, an internal process for realizing the above-described processing operation by the video distribution system will be described with reference to FIG.

The video is distributed from the video distribution means 14 to the terminal 2 (step S101). The distributed video is reproduced by the video display means 15 of the terminal 2 (step S10).
2). The user operates the slider 32 to determine a range in which a high-quality image is desired (for example, the range 37 in FIG. 2). At this time, the position where the marking button 34 is pressed (the position 32A in FIG. 2) is the start position, and the position where the marking button 34 is released (the position 32A in FIG. 2).
The playback position acquisition means 21 recognizes and acquires B) as the end position (step S103).

It should be noted that video data is generally managed in still images in units of frames, and can be handled in frame units. Therefore, the start position and the end position are the start position frame (frame number 1) of the video for distribution.
It is acquired by the number of elapsed frames from. It should be noted that the reproduction means, that is, the reproduction position acquisition means 21 of the terminal 2, for example, often manages the elapsed seconds (elapsed time). However, since the relationship between frames and seconds is 1 second = 30 frames, Is possible.

The start frame number and the end frame number acquired by the reproduction position acquisition means 21 are
(Step S10).
4) Further, it is passed to the video clipping means 23. The video clipping means 23 performs a process of clipping the original video data 11 in frame units based on the start frame number and the end frame number (step S105). The video data clipped in this way is passed from the video clipping means 23 to the video control means 16.

By the way, the process of cutting out the original video data 11 is expected to require a predetermined processing time. During the clipping process by the video clipping means 23, the terminal 2
Nothing is displayed on the video display means 15 on the side. Therefore, the video control unit 16 immediately determines the range in which the user desires high-quality video distribution (reference numeral 30 in FIG. 2).
(See # 3), that is, immediately after the marking button 34 is released, the advertisement video data 17 prepared in advance
Is passed to the video distribution means 14 (step S106). The video distribution unit 14 distributes the advertisement video data 17 to the terminal 2 via the network 3 (Step S107). The advertisement video based on the advertisement video data 17 is reproduced by the video display means 15 of the terminal 2 (step S10).
8) is displayed on the image display surface 31 (reference numeral 30 in FIG. 2).
(See # 4).

The video control means 16 stores the advertisement video data 17
During the distribution, the high-quality video (video data in the specified range) from the clipping unit 23 is held, and after the distribution of the advertisement video data 17 is completed, the high-quality video is passed to the video distribution unit 14 (step S109). Video distribution means 1
4 distributes the high-quality video in the specified range to the terminal 2 following the advertisement video data (step S110). Thus, the video display means 15 of the terminal 2 reproduces the high-quality video following the advertisement video (step S111). That is, the high-quality image is displayed on the image display means 15, that is, the image display surface 31 of the display / operation unit 30 without interruption.

As described above, according to the first embodiment, unlike an advertiser, an advertiser plays an advertisement before a video desired by the user, so that the advertiser always sees the user. This has the effect of increasing the degree of attention. Also, for the video distributor, it is possible to switch between the low-quality video for preview and the high-quality video to be originally distributed according to the user's request, and particularly without creating a new digest version, There is an effect that such a video distribution system can be operated.

Embodiment 2 Next, a second embodiment of the present invention will be described. In the second embodiment, unlike the first embodiment in which a predetermined advertisement video is inserted before video distribution, a video distribution system that selects and distributes an advertisement video in combination with a map is used. I assume.
