In a situation in which about nine moving images have been reproduced, an arbitrary moving image can be selected by rotating the cylinder.

[0003]

However, in the above-mentioned conventional technology, the position of a moving image arranged in space is fixed and random, and it is difficult for a user to find an arbitrary moving image at high speed. There was a problem that is. Further, since the number of videos that can be arranged is limited to about several tens, there is a problem that a large number of videos cannot be handled.

[0004] It is an object of the present invention to provide a moving picture presenting method that allows a user to quickly find an arbitrary moving picture and handle a large amount of moving pictures.

[0005]

According to the moving picture presenting method of the present invention, a user designates a moving picture group identifier and n (n is an integer of 1 or more) evaluation axes through a user terminal to present a moving picture. Request, a video identifier corresponding to the video group identifier, a video group identifier list is searched from the video DB, and the video identifier, the evaluation information corresponding to the evaluation axis for each video corresponding to the video group identifier is provided by an evaluation information providing server. From the evaluation axis, place and play the video from the evaluation information, obtain an advertisement video from the advertisement providing server, place and play the advertisement video on the space, When the user returns a space corresponding to the moving image identifier and requests reproduction of the moving image via the user terminal via the user terminal, the moving image corresponding to the moving image identifier is displayed on the full screen via the both terminals. Play using.

[0006] When arranging moving images in a space, sorting is performed on an arbitrary evaluation axis, so that a user can find any moving image at high speed. For example, if the moving images are sorted by the number of times they have been viewed, the most popular moving images come to the foreground, so that the moving images can be found faster than if they were randomly arranged.

In contrast to the usual method of arranging moving images two-dimensionally (method of arranging CATV channels as thumbnails), the present invention can arrange moving images three-dimensionally. Can be placed (can be handled). For example, in the case of two dimensions, 5 × 5 = 25 sheets, but in the case of three dimensions, 5 × 5 × 5 = 125 sheets.
