  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to embodiment shown below. These embodiments are merely examples, and the present invention can be implemented in various modifications and improvements based on the knowledge of those skilled in the art. In the present specification and drawings, the same reference numerals denote the same components.

  FIG. 1 shows a configuration example of a video display system according to an embodiment of the present invention. The video display system according to the present embodiment includes a service dedicated server 10, a streaming server 20, and a user terminal 30.

  The streaming server 20 distributes live video. Live video is optional. For example, it is not limited to cultural images such as music live, DJ events, and rakugo, but may be sports broadcasts or business images such as presentations and conferences.

  FIG. 2 shows a configuration example of the user terminal 30. The user terminal 30 includes an information processing unit 11, a storage unit 12, and a communication processing unit 13. The information processing unit 11 includes an authentication unit 111 and a video composition unit 112. The user terminal 30 is an arbitrary terminal capable of viewing live video, and is, for example, a personal computer, a tablet, a mobile phone, or a smartphone.

  The user terminal 30 may be realized by causing a computer to function as the authentication unit 111 and the video composition unit 112. In this case, each configuration is realized by a CPU (Central Processing Unit) in the user terminal 30 executing the computer program stored in the storage unit 12.

  The authentication unit 111 authenticates a user who wants to view live video. For example, the service dedicated server 10 is inquired for the account number and password input to the user terminal 30. The service dedicated server 10 may have a function of constructing SNS (social networking service). In this case, the service dedicated server 10 authenticates that it is a predetermined group that constitutes the social network. The predetermined group may be designated by the user himself / herself. In this case, only users belonging to the group can participate in the common virtual space. As a result, it is possible to view the live video in a closed state in which no user other than the designated user participates.

  If the authentication by the authentication unit 111 is successful, the communication processing unit 13 receives content from the streaming server 20. The video composition unit 112 generates a spatial video in which a user identification mark is arranged in a virtual space where a live video can be viewed.

  The identification mark is optional. For example, an icon in which information capable of identifying the user is described in a predetermined frame. The identifiable information is, for example, a photograph or a character. The identifiable information may be determined by the account used when the user is authenticated. For example, when a user is authenticated with an account of a social network service, the user's profile picture or avatar is displayed as an icon.

  FIG. 3 shows a display example of a virtual space where a live video can be viewed. A screen 31 for displaying live video is displayed in the three-dimensional virtual space. Around this screen 31, an icon 32 for displaying each user who views the live video is displayed. One of the icons 32 is the user A. The virtual space displayed on the user terminal 30 of the user A is the viewpoint of the user A in the virtual space. For this reason, the icon 32 of the user A is not displayed on the user terminal 30 of the user A.

  The virtual space is composed of a combination of a view of the world, a background, a building, an installation, and a decoration according to the theme of live video. For example, if the live video is outdoor live, the virtual space is set to an outdoor stage. If the live video is soccer, make the virtual space a soccer stadium.

  When the user A has an account of a live performer, as shown in FIG. 4, an image displaying a landscape from the stage may be displayed on the user terminal of the user A.

  User A can move in the virtual space. For example, when a control signal indicating that the user terminal 30 of the user A moves is transmitted to the user terminal 30, the video composition unit 112 moves the position of the user A in the virtual space according to the control signal, and the user A of the destination user A Synthesize a virtual space according to the viewpoint. As a result, the user A can view the live delivery moving image at a favorite angle from a favorite position in the 3D space. In addition, the user A can see a favorite direction and a favorite angle, not limited to the screen 31 such as the sky, the ground, and the back.

For example, when the user A moves the cursor upward in the vertical direction Dv, the video composition unit 112 brings the position of the user A to the screen 31. Then, the video distribution unit 113 transmits the video when the screen 31 is viewed up to the user terminal 30. Thereby, the user A can see the screen 31 up as shown in FIG.
For example, when the user A moves the cursor downward in the vertical direction Dv, the video composition unit 112 moves the position of the user A away from the screen 31. Then, the video distribution unit 113 transmits a video when the screen 31 is viewed from a distance to the user terminal 30. Thereby, the user A can view the screen 31 by zooming out.
For example, when the user A moves the cursor to the left side in the horizontal direction Dh, the video composition unit 112 moves the position of the user A to the left. Then, the video distribution unit 113 transmits a video when the screen 31 is viewed from an oblique direction to the user terminal 30. Thereby, the user A can see the screen 31 from diagonally as shown in FIG.

  As the user A moves in the virtual space, the display of each icon 32 also changes. For example, when the user A approaches the screen 31, the number of icons 32 displayed on the user terminal 30 decreases. When the user A moves to the left, it is displayed that the user of the icon 32 hidden behind the user B icon 32 shown in FIG. In this way, the user A can move among the users who are viewing the live video as if it were an actual live venue.

  Here, the moving method of the user A is not limited to the movement of the cursor, and any means can be adopted. For example, the movement of the display of the user terminal 30 may be detected using an accelerometer, and the user A may be moved in accordance with the movement, or the scenery that the user A can see may be changed.

  The icon 32 is preferably capable of various operations as well as movement. For example, jumping, bowing, twisting left and right, rotating or sliding, and combinations thereof. Accordingly, the user A can appeal to a live video distributor and other spectators.

  In the video display system according to the present embodiment, conversations between users are possible. For example, in the state where the virtual space shown in FIG. 3 is displayed on the user terminal 30 of the user A, the user B icon 32 is selected, a character is entered in the text box 33 to create a message, and the send button is pressed. Then, the video composition unit 112 transmits the message transmitted from the user A to the user terminal 30 of the user B. Thereby, it is displayed that the message has arrived from the user A to the user terminal 30 of the user B. When user B looks back, the state shown in FIG. 4 is obtained, and user A and the message can be seen therein. In this manner, the “speaker” can specify the “partner” and input the speech by inputting text.

  The message transmission destination may be selected by directing the front of the transmission source icon 32 to the transmission destination icon 32 as shown in FIG. In this case, the video composition unit 112 identifies the user of the icon 32 positioned in front of the transmission source icon 32. When the transmission destination icon 32 can be specified, the video composition unit 112 can identify the transmission destination icon 32. When the transmission destination icon 32 can be specified, the video composition unit 112 moves the front of the transmission destination icon 32 toward the transmission source icon 32. It is preferable to point. At this time, a message is displayed in a balloon from the transmission source icon 32. As a result, the transmission destination user can view the message with the transmission source user. In this case, it is preferable to return to the original direction after a certain time. It is also possible to cancel at an arbitrary timing and return to the original direction. When the transmission destination icon 32 can be specified, the video composition unit 112 does not have to face the transmission destination icon 32 toward the transmission source icon 32.

  The conversation includes a conversation by voice as well as a conversation by characters such as a text message. This also allows voice chat. In addition, it may be possible to provide gifts to performers of live video and other users.

  The movable range of user A is arbitrary. For example, as shown in FIG. 8, the virtual space may be in a weightless state. Each spectator indicated by the icon 32 is not affected by gravity in the 3D space and can move to a desired position. It can be positioned while floating in the air and can move around in the air. As a result, it is possible to provide a user with a stereoscopic effect and floating feeling that cannot be obtained in two dimensions.

  The movable range of the user A may be limited. For example, the icon 32 is arranged at a specific position, and each user views a live video displayed on the screen 31 from the specific position. The specific position is, for example, a seat position predetermined for each user such as a spectator seat or a conference room in a stadium. Here, the arrangement of the seats may be spherical, and each seat may be suspended in the air.

  The movable range of the user A may be limited. For example, the user viewable area in the virtual space may be divided by zone to limit the zones that can participate. The zones that can participate are limited according to the ticket purchase amount, for example. For example, the A seat zone is limited to A seat ticket purchasers, the B seat zone is limited to B seat ticket purchasers, and the C seat zone is limited to free members. Moreover, you may limit the zone which can participate according to the membership class of a social network. For example, the sand cover zone is limited to premium members, and the S seat zone is limited to general paying members.

  An example in which the range in which the user A can move is limited, for example, includes a case where the user A moves in a predetermined formation. For example, the screen 31 is surrounded around the screen 31 as shown in FIG. 9 and slowly moves around the screen 31. Thereby, live viewing can be performed in a state in which a group chat formation is formed in a virtual space.
