Abstract

A video distribution device includes: an acquisition unit for acquiring multiple videos of the same object shot from different angles; a storage unit for associating a still image for a predetermined duration of time extracted from each of the multiple videos with information indicating an angle at which the corresponding video is shot, and storing the associated still image in a chronological order; a reception unit for receiving an angle for viewing the object designated via an information processing terminal; and a control unit for performing a control in which each time the reception unit receives the designated angle, a still image corresponding to the angle is obtained from the storage unit, and the still image corresponding to the angle is transmitted to the information processing terminal in the chronological order where the still image is stored.

Claims

1. A video distribution system comprising:

a plurality of mobile terminals including a plurality of imaging units arranged to surround a subject, wherein the imaging units include cameras that image the subject from a plurality of different angles, and a recording function that records multiple videos obtained through imaging, and the imaging units transmit the recorded videos to a wireless network;

a server including;

an acquisition unit that acquires the multiple videos from the mobile terminals through the wireless network, the multiple videos being obtained by the mobile terminals configured by the imaging units imaging the subject;

a generation unit that extracts a frame for each of the multiple videos acquired by the acquisition unit through the wireless network for a predetermined time, converts the frame into a format of a hypertext markup language HTML as a still image, and generates HTML data where an angle at which each video is imaged is associated with time in which the video is imaged; and

a storage unit that stores the HTML data in a chronological order; and

an information processing terminal that receives a designation of an angle for viewing the subject by a user sliding a finger on a screen in a state where the finger is in contact with the screen to perform a swiping operation on the screen, wherein

the server further includes;

a reception unit that receives the designation of the angle for viewing the object subject via the information processing terminal; and

a control unit configured such that;

during the swiping operation, each time the reception unit sequentially receives the designation of the angle that changes based on the swiping operation, the control unit performs a control such that the HTML data of the still image corresponding to the angle is obtained from the storage unit, and transmitted through the wireless network to the information processing terminal, and

after the swiping operation is completed, the control unit performs a control such that the HTML data of the still image corresponding to the angle at a time after the swiping operation is completed is transmitted through the wireless network to the information processing terminal in a chronological order in which the HTML data is stored,

during the swiping operation, the information processing terminal displays, by the HTML data received from the server, the still image of the subject corresponding to the angle that changes based on the swiping operation, and

after the swiping operation is completed, the information processing terminal sequentially receives and displays the HTML data of the still image at an angle corresponding to a position at which the swiping operation is completed to display a pseudo video at the angle corresponding to the position at which the swiping operation is completed.

2. The video distribution system according to claim 1, further comprising a provision unit that provides a web page to provide the video, wherein

the control unit transmits the still image to be displayed on the web page, and transmits the web page in which contents of sequential still images are changed in the chronological order to provide the information processing terminal with the pseudo video.
