[0004] [Patent Document 1] JP 2003-163911 A Summary of the Invention [Problem to be solved by the invention]

[0005] The video playback control method described in Patent Document 1 is intended for a community consisting of multiple users who are far apart, and is not intended for a community in which all the users gather in close proximity to watch the same video together.

[0006] In other words, there is a need for technological development that allows users to enjoy watching videos more even when all users are gathered in close proximity to watch the same video together. As one concept of this technological development, there is a new need for users who are gathered in close proximity to be able to watch videos while communicating with each other.

[0007] The present invention has been made in consideration of the above circumstances, and aims to provide an information processing device, a video distribution method, and a video distribution program that can encourage users to watch videos while communicating with each other. [Means for solving the problem]

[0008] In order to solve the above problems, an information processing device, a video distribution method, and a video distribution program according to the present invention employ the following means.

[0009] In order to solve the above problems, an "information processing device" which is one aspect of the present invention is an information processing device which distributes video data to a plurality of information processing terminals, and is equipped with a group registration means which accepts registration of a group consisting of a plurality of information processing terminals located in close proximity, and a video data distribution means which distributes the video data to the plurality of information processing terminals registered as the group, and the video data distribution means distributes group video data indicating videos that cannot be viewed unless registered as the group, to the information processing terminals registered as the group.

[0010] In order to solve the above problems, a "video distribution method" according to one embodiment of the present invention is a video distribution method for distributing video data to a plurality of information processing terminals, the method comprising: a first step of accepting registration of a group consisting of a plurality of information processing terminals located in close proximity; and a second step of distributing the video data to the plurality of information processing terminals registered as the group, the second step distributing group video data indicating a video that cannot be viewed unless the information processing terminal is registered as the group, to the information processing terminals registered as the group.

[0011] In order to solve the above problems, a "video distribution program" which is one aspect of the present invention causes a computer to function as a group registration means which accepts registration of a group consisting of multiple information processing terminals located in close proximity, and a video data distribution means which distributes, to the information processing terminals registered as the group, video data indicating videos that cannot be viewed unless the information processing terminals are registered as part of the group.

[0012] The above-mentioned "information processing device" may be subject to various technical limitations, as exemplified below. In addition, technical limitations of the same purport may be applied to the processing steps executed by the "video distribution method" or the functions of the "video distribution program."

[0013] The moving image data distribution means distributes the group moving image data which is to be played back simultaneously on a plurality of the information processing terminals registered as the group to form a single moving image.

[0014] The moving image data distribution means distributes the group moving image data, which is treated as one moving image when a user views the group moving image data by arranging the plurality of information processing terminals in a plane or three-dimensional manner.

[0015] The moving image data distribution means distributes the group moving image data so that at least one of images and sounds reproduced is different in at least some of the information processing terminals registered as the group.

[0016] The moving image data distribution means distributes the group moving image data distributed to some of the information processing terminals to the other information processing terminals thereafter.

[0017] The video data distribution means distributes the group video data, which includes elements that cannot be viewed on the information processing terminals not registered as part of the group, to the information processing terminals registered as part of the group.

[0018] The element is at least one of an image and a sound to be reproduced.

[0019] The video data distribution means distributes the group video data when the viewing environment of the information processing terminal satisfies a predetermined condition.

[0020] The audio-visual environment is at least one of brightness and sound detected by the information processing terminal.

[0021] The group registration means acquires location information of the information processing terminal via the information processing terminal, and registers, as a group, a plurality of the information processing terminals that are within a range that is predetermined as the close distance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An information processing device, a video distribution method, and a video distribution program according to an embodiment of the present invention will be described below with reference to the drawings.

[0025] [1. First embodiment] A first embodiment of the present invention will now be described.

[0026] [1-1. Video distribution system configuration] 1 is a schematic diagram of a video distribution system 1 according to this embodiment. The video distribution system 1 includes a communication line 2, a plurality of mobile terminals 3, and a server 4.

[0027] The communication line 2 forms a computer network, and is, for example, a wide area communication line provided by an electric utility company.

[0028] The mobile terminal 3 is, for example, an information processing terminal such as a smartphone, a tablet terminal, or a notebook computer. The mobile terminal 3 includes a touch panel display 3a for displaying images, a speaker 3b for outputting sound, a microphone 3c for inputting sound, and a camera 3d for capturing an image of a subject. In order to play back video data distributed from the server 4, for example, dedicated application software is installed on the mobile terminal 3.

[0029] The server 4 is an information processing device that distributes video data to a plurality of mobile terminals 3 via the communication line 2. The video data indicates video that has a story, such as an anime or a drama, and the story progresses along the story. The server 4 distributes the video data to the mobile terminals 3, for example, by non-live distribution rather than live distribution. The mobile terminal 3 that receives the video data plays the video data and displays it on the touch panel display 3a, and outputs sound from the speaker 3b.

[0030] The multiple mobile terminals 3 to which the video data is delivered are located in close proximity to each other and are registered in the server 4 as a group 5 (hereinafter referred to as "group registration"). That is, the multiple mobile terminals 3 registered as a group display videos based on the video data delivered from the server 4 at the same time, in other words, synchronously, on their touch panel displays 3a. Then, each user of the mobile terminals 3 registered as a group will watch the videos at the same time.

[0031] 1, group 5 is made up of four mobile terminals 3, but this is just an example, and the number of mobile terminals 3 is not limited as long as group 5 is made up of a plurality of mobile terminals 3. In addition, the types of mobile terminals 3 making up group 5 are not limited, and a mixture of smartphones, tablet terminals, notebook computers, etc. may be used.

[0032] [1-2. Server configuration] FIG. 2 is a block diagram showing the electrical configuration of the server 4 according to the present embodiment.

[0033] The server 4 according to this embodiment includes a CPU (Central Processing Unit) 20, which is the main control unit responsible for the operation of the entire server 4, a ROM (Read Only Memory) 22 in which various programs and various data are pre-stored, a RAM (Random Access Memory) 24 used as a work area when the CPU 20 executes various programs, and an HDD (Hard Disk Drive) 26 as a storage means for storing various programs and various data.

[0034] The HDD 26 stores information about the registered group 5 and video data to be distributed to the mobile terminal 3. Note that the storage means is not limited to the HDD 26, and may be, for example, another storage medium such as a semiconductor memory, such as a flash memory.

[0035] Furthermore, the server 4 is equipped with an operation input unit 28 composed of a keyboard, a mouse, etc. and which accepts input of various operations, a monitor 30 such as a liquid crystal display device for displaying various images, and an external interface 32 which is connected to other information processing devices such as a mobile terminal 3 via the communication line 2 and which transmits and receives various data to and from the other information processing devices.

[0036] The CPU 20, ROM 22, RAM 24, HDD 26, operation input unit 28, monitor 30, and external interface 32 are electrically connected to one another via a system bus 34. Therefore, the CPU 20 can access the ROM 22, RAM 24, and HDD 26, grasp the operation state of the operation input unit 28, display images on the monitor 30, and transmit and receive various data to and from other information processing devices, etc. via the external interface 32.

[0037] [1-3. Video distribution function of the server according to this embodiment] FIG. 3 is a functional block diagram relating to the video distribution function of the server 4 according to this embodiment.

[0038] The CPU 20 of the server 4 includes a group registration unit 40, a video data distribution unit 42, and a distribution video selection unit 44. Each function of the CPU 20 is realized by a program stored in the HDD .

[0039] The group registration unit 40 accepts registration of a group 5 made up of a plurality of mobile terminals 3 located in close proximity.

[0040] The group registration unit 40, for example, acquires location information of the mobile terminal 3 via the mobile terminal 3, and registers a plurality of mobile terminals 3 that are within a predetermined range as a close distance (for example, within 10 m, hereinafter referred to as the "close distance range") as a group 5. Note that a user ID (identification) is also acquired together with the location information of the mobile terminal 3. The user ID is used as an ID to be entered into a login screen when the user receives a video distribution service.

[0041] Whether or not there is a mobile terminal 3 in the close range can be determined by, for example, a single mobile terminal 3 designated as a host. This is determined based on whether or not a mobile terminal 3 located within a diameter of 10 m around the host terminal (hereinafter referred to as the "host terminal") is within the close distance range. More specifically, the registration of a group 5 is initiated when the host mobile terminal 3 first logs into the video distribution service, and the other mobile terminals 3 apply for permission to join the registered group 5. The permission application by the other mobile terminals 3 is approved or rejected by the host terminal, and the group registration unit 40 determines whether or not the distance between the host terminal and the other mobile terminals 3 is within the close distance range.

[0042] Only when the group registration unit 40 determines that the other portable terminal 3 is within the close distance range, does the group registration unit 40 permit the other portable terminal 3 to be registered in the group 5 in accordance with the permission of the host terminal. On the other hand, when the group registration unit 40 determines that the other portable terminal 3 is not within the close distance range, the group registration unit 40 does not permit the other portable terminal 3 to be registered in the group 5 even if the host terminal grants permission.

[0043] The group registration unit 40 may register the group 5 only by registering the user ID, without acquiring the position information of the portable terminal 3. In this case, whether or not permission is granted to the other portable terminals 3 is determined only by the host terminal.

[0044] The video data delivery unit 42 delivers video data to a plurality of mobile terminals 3 registered in a group. As an example, the video data delivery unit 42 delivers video data to all of the mobile terminals 3 registered in the group. Note that the delivery of the video data is performed by streaming playback, as an example.

[0045] The video data delivery unit 42 according to the present embodiment is capable of delivering video data to mobile terminals 3 that are not registered in a group. On the other hand, for mobile terminals 3 that are registered in a group, the video data delivery unit 42 delivers video data indicating a video that cannot be viewed unless the mobile terminal is registered in the group. (hereinafter referred to as "group video data") will be distributed.

[0046] In the following description, video data distributed to a mobile terminal 3 that is not registered in a group is referred to as normal video data. In the video distribution system 1 according to the present embodiment, videos that can be viewed by playing back normal video data are complete, and a user can understand the progress of the video by only playing back the normal video data.

[0047] The process of distributing group video data is called group viewing video distribution process. As an example, the group viewing video distribution process according to the present embodiment switches from normal video data to group video data as the video progresses and distributes the data to mobile terminals 3 registered as a group.

[0048] The timing of the video progression where the distribution of normal video data is switched to the distribution of group video data is called a group viewing branch. For mobile terminals 3 that are not registered in a group, the distribution of normal video data continues even when the group viewing branch is reached, without switching from normal video data to group video data.

[0049] The distribution video selection unit 44 selects video data to be distributed by the video data distribution unit 42, and reads it from the HDD 26. That is, for mobile terminals 3 registered in a group, when the progress of the video has reached a group viewing branch, the distribution video selection unit 44 selects group video data, reads it from the HDD 26, and distributes it to the video data distribution unit 42. On the other hand, when the progress of the video has not reached a group viewing branch, the distribution video selection unit 44 selects normal video data, reads it from the HDD 26, and distributes it to the video data distribution unit 42.

[0050] [1-4. Details of group viewing video distribution processing according to this embodiment] The group viewing video distribution process according to this embodiment will be described with reference to FIGS.

[0051] FIG. 4 is a diagram showing an example of a video 50 displayed on the mobile terminals 3A to 3D registered as a group in the group viewing branch.

[0052] The group viewing video distribution process described with reference to Fig. 4 distributes group video data that is made into one video 50 by being simultaneously played on a plurality of mobile terminals 3A-3D registered in a group, and different videos are played on all of the mobile terminals 3. Note that in the example of Fig. 4, it is assumed that when the progress of the video reaches a group viewing branch, the users will view the video by arranging the plurality of mobile terminals 3A-3D in a plane.

[0053] Video 50A1 displayed on mobile terminal 3D is video 50 displayed by playing normal video data, that is, video 50 that is displayed on mobile terminals 3 that are not registered in a group. On the other hand, videos 50B1-1 to 50B1-3 displayed on mobile terminals 3A to 3C are videos 50 displayed by playing group video data. Therefore, videos 50B1-1 to 50B1-3 are videos that cannot be viewed on mobile terminals 3 that are not registered in a group.

[0054] 4, moving pictures 50B1-1 to 50B1-3 display the background of moving picture 50A1, and by combining moving pictures 50B1-1 to 50B1-3 with moving picture 50A1, a moving picture with a wider angle of view is formed compared to when only moving picture A1 is played. Then, by viewing moving pictures 50B1-1 to 50B1-3 simultaneously with moving picture 50A1, the user can understand them as one moving picture.

[0055] In this way, the group viewing video distribution process described using Figure 4 allows users to watch videos by arranging multiple mobile terminals 3 registered as a group, thereby encouraging users to watch videos while communicating with each other.

[0056] It should be noted that the mobile terminals 3 to which the group video data is delivered are determined randomly by the video data delivery unit 42, as an example.

[0057] Also, in the example of Figure 4, the number of mobile terminals 3 registered in the group matches the number of mobile terminals 3 required to create one video 50 (hereinafter referred to as the "required number of terminals"), but there may be cases where the number of mobile terminals 3 registered in the group does not match the required number of terminals.

[0058] When the number of mobile terminals 3 registered in the group is greater than the required number of terminals, for example, each group video data may be played on one mobile terminal 3, and the number of mobile terminals 3 that play normal video data may be two or more. Also, when the number of mobile terminals 3 registered in the group is less than the required number of terminals, the number of mobile terminals 3 that play normal video data may be at least one, and some of the group video data may be played on other mobile terminals 3.

[0059] In addition, in Fig. 4, a form in which a plurality of mobile terminals 3 registered as a group are arranged in a plane (two-dimensional form) has been described, but the present invention is not limited to this, and a form in which a plurality of mobile terminals 3 registered as a group are arranged in a three-dimensional form (three-dimensional form) as shown in Fig. 5. In the example of Fig. 5, two mobile terminals 3 are arranged so that the other two mobile terminals 3 are approximately perpendicular to the major axis direction of two mobile terminals 3, but the three-dimensional arrangement is not limited to this.

[0060] By arranging a plurality of mobile terminals 3 in a three-dimensional manner, it is possible to provide a user with a three-dimensional field of view in a video set in a dungeon such as a cave or labyrinth, for example.

[0061] FIG. 6 shows a case where images reproduced on at least some of the mobile terminals 3A to 3D registered in a group are different.

[0062] The video 50A2 displayed on the mobile terminals 3A, 3C, and 3D is a video 50 that is displayed by playing normal video data, i.e., a video 50 that is also displayed on a mobile terminal 3 that is not registered in a group. On the other hand, the video 50B2 played on the mobile terminal 3B is a video 50 that is displayed by playing group video data. In other words, the video 50B2 displayed on the mobile terminal 3B is a video that cannot be viewed on a mobile terminal 3 that is not registered in a group.

[0063] 6, video 50B2 also shows a person who is conversing with a person who appears in video 50A2, in other words, video 50B2 is a video with a different camera angle from video 50A2. A user watching video 50A2 can then clearly see who the person in video 50A2 is conversing with by watching video 50B2 at the same time.

[0064] Group viewing branching with different camera angles, as shown in Fig. 6, is called angle branching. Examples of angle branching include a close-up of the main character in the same scene in some of the videos on the mobile terminals 3, a foreshadowing event being displayed in the videos on some of the mobile terminals 3, and a scene in which multiple characters respond individually to a call and one character is displayed on each mobile terminal 3.

[0065] In addition, in angle branching, it is not necessary to line up a plurality of mobile terminals 3 as shown in Fig. 4. Each user of the mobile terminal 3 may only watch the video played on his / her own mobile terminal 3.

[0066] FIG. 7 is a diagram showing a form in which group video data distributed to some mobile terminals 3 is then distributed to other mobile terminals 3 in angle branching.

[0067] Fig. 7(A) shows a state of video display on a mobile terminal 3B where group video data is played. In the example of Fig. 7(A), a notification image 52 such as "original screen displaying" is displayed so that the user can recognize that the video displayed on the mobile terminal 3B is an original video 50B3 different from the other mobile terminals 3A, 3C, 3D. Also, a share button 54 for sharing the video is displayed on the mobile terminal 3B.

[0068] If a user notices that the video displayed on his / her mobile terminal 3B is not displayed on the other mobile terminals 3A, 3C, 3D, he / she can tap the share button 54 to cause the other mobile terminals 3A, 3C, 3D to display the same video as his / her own video.

[0069] That is, when the share button 54 is tapped, the server 4 also distributes the group video data to the other mobile terminals 3A, 3C, 3D. As an example, as shown in Fig. 7(B), the other mobile terminals 3A, 3C, 3D to which the new group video data has been distributed may display a video 50B3 obtained by playing back the group video data by superimposing it on a video 50A3 obtained by playing back normal video data using a wipe 56, or may switch from playing normal video data to playing the group video data.

[0070] In the group viewing video distribution process as shown in FIGS. 6 and 7, group video data is distributed to some of the mobile terminals 3B registered in the group, so that the users of the other mobile terminals 3A, 3C, and 3D need to view the video 50B3 reproduced from the group video data by communicating with the user of the mobile terminal 3B. For this reason, the group viewing video distribution process can encourage users to view the video while communicating with each other. In addition, the users of the other mobile terminals 3A, 3C, and 3D may not be able to view the video reproduced from the group video data by viewing the video only once. For this reason, it is expected that the users will want to view the video a second time by arranging multiple mobile terminals 3A to 3D side by side, so the group viewing video distribution process can encourage users to view the video while communicating with each other.

[0071] Furthermore, the group viewing video distribution process may distribute group video data such that at least one of the images and sounds reproduced is different. That is, sounds output from some mobile terminals 3 may be different from sounds output from other mobile terminals 3. Furthermore, images and sounds reproduced from some mobile terminals 3 may be different from those reproduced from other mobile terminals 3.

[0072] For example, a scream of one of the characters in a video is output from some of the mobile terminals 3 that are not registered in a group, and then a video in which the other characters turn around is played on all of the mobile terminals 3. Note that since the scream is not output to the mobile terminals 3 that are not registered in a group, even if a video in which the other characters turn around is then played, the user watching the video will not immediately understand what has happened.

[0073] Then, if the voice of some of the mobile terminals 3 is different from the voice of the other mobile terminals 3, the users of the other mobile terminals 3 will inevitably know this because they are in close proximity. Therefore, the users of the other mobile terminals 3 will communicate with the users of some of the mobile terminals 3 in order to find out what the voice is. In addition, since it is expected that there will be a desire to view a second video on multiple mobile terminals 3 side by side, the group viewing video distribution process can encourage users to watch videos while communicating with each other.

[0074] [1-5. Group viewing video distribution processing flow according to this embodiment] 8 is a flowchart showing the flow of the group viewing video distribution process according to this embodiment executed by the CPU 20 of the server 4. A program for executing the group viewing video distribution process is pre-stored in a predetermined area of ​​the HDD 26. The group viewing video distribution process is started together with the start of distribution of normal video data.

[0075] First, in step 100 , the distributed moving image selection unit 44 determines whether the progress of the moving image has reached a group viewing branch. If the determination is affirmative, the process proceeds to step 102 , and if the determination is negative, the process proceeds to step 110 .

[0076] In step 102, the distribution moving image selection unit 44 judges whether or not the mobile terminal 3 is registered in the group. If the judgment is affirmative, the process proceeds to step 104, and if the judgment is negative, the process proceeds to step .

[0077] In step 104, the distribution moving image selection unit 44 selects group moving image data and normal moving image data according to the group viewing branch, and the process proceeds to step 108. The selected group moving image data and normal moving image data are distributed by the moving image data distribution unit 42 to the mobile terminals 3 registered in the group.

[0078] In step 106, the distribution moving image selection unit 44 selects only the normal moving image data, and the process proceeds to step 108. The selected normal moving image data is distributed by the moving image data distribution unit 42 to mobile terminals 3 that are not registered in the group.

[0079] In step 108 , the video data delivery unit 42 delivers the video data selected in step 104 or step 106 to the mobile terminal 3 .

[0080] In the next step 110, the distribution moving image selection unit 44 judges whether or not distribution of the moving image has ended. If the judgment is negative, the process returns to step 100, and if the judgment is positive, the group viewing moving image distribution process ends.

[0081] As described above, the group viewing video distribution process according to the present embodiment distributes group video data indicating videos that cannot be viewed without group registration to group-registered mobile terminals 3. Therefore, in order to view videos played using group video data, it becomes necessary to group-register the mobile terminals 3 of multiple users and have the users view the videos in close proximity to each other, and therefore the group viewing video distribution process can encourage users to view the videos while communicating with each other.

[0082] [2. Second embodiment] A second embodiment of the present invention will now be described.

[0083] The configurations of the moving image distribution system 1 and the server 4 according to this embodiment are similar to those of the moving image distribution system 1 and the server 4 according to the first embodiment shown in FIGS. 1 to 3, and therefore a description thereof will be omitted.

[0084] In addition, the video data distribution unit 42 in this embodiment distributes group video data including elements (hereinafter referred to as "group viewing elements") that cannot be viewed on mobile terminals 3 that are not registered in the group to mobile terminals 3 that are registered in the group.

[0085] [2-1. Details of the group viewing video distribution process according to this embodiment] The group viewing video distribution process according to this embodiment will be described with reference to Fig. 9. In the example shown in Fig. 9, the group viewing element is an image. In the group viewing video distribution process according to this embodiment, as an example, the same video data is distributed to all mobile terminals 3 registered in the group at the group viewing branch, and the same video is played. That is, in the group viewing video distribution process according to this embodiment, the group viewing element is viewable on all mobile terminals 3 registered in the group, but this is not limiting, and the group viewing element may be viewable only on some of the mobile terminals 3 registered in the group.

[0086] FIG. 9(A) shows a video 50A4 displayed on a mobile terminal 3 that is not registered in a group, and FIGS. 9(B) and (C) show videos 50B4-1 and 50B4-2 displayed on a mobile terminal 3 that is registered in a group.

[0087] In FIG. 9(B), image 70 included in video 50B4-1 is a group viewing element, and users cannot view image 70 on mobile terminals 3 that are not registered in the group.

[0088] In the group viewing video distribution process according to this embodiment, when a group viewing branch is reached, group video data in which the group viewing elements can be viewed is distributed to all mobile terminals 3 registered in the group, while normal video data in which the group viewing elements cannot be viewed is distributed to mobile terminals 3 that are not registered in the group.

[0089] In addition, the group video data may be subjected to image processing on the group viewing element, and the image processing may be made cancelable on the mobile terminal 3. That is, when the progress of the video reaches a group viewing branch, the mobile terminal 3 not registered in the group plays the video without canceling the image processing on the group video data, while the mobile terminal 3 registered in the group plays the video by canceling the image processing on the group video data. Note that the image processing may be any image processing that indicates the presence of a group viewing element, such as mosaic processing or filling in a predetermined color. This allows the user to recognize that the video that has been image processed is being viewed when the group video data is played on the mobile terminal 3 not registered in the group. Such image processing can encourage the user to perform group registration on the mobile terminal 3.

[0090] 9C, the range (hereinafter referred to as the "enlarged image range") 72 indicated by the dashed line in which the angle of view of video 50B4-2 is enlarged compared to video 50A4 is the group viewing element. In other words, the user cannot view the enlarged image range 72 on a mobile terminal 3 that is not registered in the group.

[0091] In the group viewing video distribution process according to this embodiment, the viewability or unviewability of the group viewing element may be controlled by changing the playback size of the group video data. That is, when the progress of the video reaches a group viewing branch, the mobile terminals 3 not registered in the group will play back the video by enlarging the playback size (horizontal and vertical dimensions) of the group video data so that the enlarged image range 72 cannot be viewed. On the other hand, the mobile terminals 3 registered in the group will play back the video without enlarging it so that the enlarged image range 72 can be viewed.

[0092] The group viewing element may be a sound reproduced from group video data. In this case, when the sound that is the group viewing element is reproduced on a mobile terminal 3 that is not registered in the group, a restriction sound (a beep) is superimposed on the sound so that the user cannot hear it.

[0093] Furthermore, when the progress of a video being played back on a mobile terminal 3 that is not registered in a group reaches a group viewing branch, a notification may be given, such as by displaying a message indicating that the group viewing element cannot be viewed.

[0094] As described above, the group viewing video distribution process according to this embodiment distributes group video data including elements that cannot be viewed on mobile terminals 3 that are not registered in the group to group-registered mobile terminals. Therefore, in order to view a video played using group video data, it becomes necessary to register the mobile terminals 3 of multiple users as a group and for the users to view the video in close proximity to each other, and therefore the group viewing video distribution process can encourage users to view the video while communicating with each other.

[0095] [3. Third embodiment] A third embodiment of the present invention will now be described.

[0096] The configurations of the moving image distribution system 1 and the server 4 according to this embodiment are similar to those of the moving image distribution system 1 and the server 4 according to the first embodiment shown in FIGS. 1 and 2, and therefore will not be described.

[0097] [3-1. Video distribution function of the server according to this embodiment] FIG. 10 is a functional block diagram relating to the video distribution function of the server 4 according to this embodiment.

[0098] The CPU 20 of the server 4 includes a group registration unit 40, a video data distribution unit 42, and a distribution video selection unit 44, as well as a viewing environment determination unit 80.

[0099] The viewing environment determination unit 80 determines whether or not the viewing environment of the mobile terminal 3 satisfies a predetermined condition (hereinafter referred to as a "group viewing condition.") The group viewing condition is determined according to the group viewing branch.

[0100] The viewing environment is information detected by the mobile terminal 3, such as brightness and sound. The brightness is detected by a camera 3d provided in the mobile terminal 3, and the sound is detected by a microphone 3c provided in the mobile terminal 3. That is, the mobile terminal 3 transmits brightness information and sound information indicating the viewing environment to the server 4. The mobile terminal 3 that detects the viewing environment is, for example, a host terminal. Note that the viewing environment may be the time and weather in addition to brightness and sound.

[0101] Furthermore, the viewing environment may include the user's operation state on the mobile terminal 3. The user's operation state is, for example, a touch operation on the touch panel display 3a of the mobile terminal 3, a shake operation on the mobile terminal 3 (an operation of shaking the mobile terminal 3), etc. The user's operation state on the mobile terminal 3 is detected by the touch panel display 3a, an acceleration sensor, etc., and the strength and number of touch operations and shake operations are also detected. Note that the strength and number of touch operations and shake operations may be individual values ​​of the mobile terminals 3 registered in a group, or may be total values ​​of multiple mobile terminals 3. In addition, the number of mobile terminals 3 that simultaneously performed a touch operation or a shake operation may be included in the group viewing condition. In this way, detecting sound, touch operations, and shake operations as the viewing environment detects the excitement state of users watching a video.

[0102] It should be noted that the microphone 3c may also receive the sound of the video being played. Therefore, the mobile terminal 3 may cancel the video sound from the sound information acquired by the microphone 3c by superimposing sound information that is in the opposite phase to the sound of the video on the sound information acquired by the microphone 3c. The mobile terminal 3 may also cancel not only the sound of the video but also noise around the mobile terminal 3. The noise may be, for example, the sound of a car running or the sound of a train.

[0103] When the viewing environment of mobile terminal 3 satisfies the group viewing conditions, distribution moving image selection unit 44 selects group moving image data to be distributed by moving image data distribution unit 42, and reads the selected moving image data from HDD 26. In other words, when the viewing environment of mobile terminal 3 satisfies the group viewing conditions, moving image data distribution unit 42 distributes the group moving image data.

[0104] [3-2. Group viewing conditions] Examples of group viewing conditions are described below.

[0105] For example, if the group viewing condition is a brightness equal to or greater than a first threshold, and the progress of the video reaches a group viewing branch and the brightness detected by mobile terminal 3 is equal to or greater than the first threshold, the dark video becomes brighter and group video data in which previously invisible images become visible is distributed. This group viewing condition is applied, for example, to a cave scene.

[0106] Furthermore, if the group viewing condition is set to a brightness equal to or less than a second threshold, and the progress of the video reaches a group viewing branch and the brightness detected by mobile terminal 3 is equal to or less than the second threshold, the bright video becomes dark and group video data in which previously invisible images become visible is distributed. This group viewing condition is applied, for example, to a scene in which a ghost appears.

[0107] In addition, the group viewing condition is set to a sound (user's voice) equal to or greater than a third threshold, and if the progress of the video reaches a group viewing branch and the sound detected by the mobile terminal 3 is equal to or greater than the third threshold, group video data in which the previously inaudible sound can be heard is distributed. This group viewing condition is applied, for example, to concert scenes.

[0108] Furthermore, the group viewing condition is set to a sound (user's voice) equal to or lower than a fourth threshold, and if the progress of the video reaches a group viewing branch and the sound detected by the mobile terminal 3 is equal to or lower than the fourth threshold, group video data in which previously inaudible sounds can be heard is delivered. This group viewing condition is applied, for example, to a scene in which bird calls are output.

[0109] Before reaching the group viewing branch, a notification such as a display of group viewing conditions may be given to the mobile terminals 3 registered in the group.

[0110] [3-3. Group viewing video distribution processing flow according to this embodiment] Fig. 11 is a flowchart showing the flow of group viewing video distribution processing according to this embodiment executed by CPU 20 included in server 4. Note that the same steps in Fig. 11 as those in Fig. 8 are given the same reference numerals as those in Fig. 8, and their explanations will be omitted in part or in whole.

[0111] In step 102, the distribution moving image selection unit 44 judges whether or not the mobile terminal 3 is registered in the group. If the judgment is affirmative, the process proceeds to step 200, and if the judgment is negative, the process proceeds to step .

[0112] In step 200, the viewing environment determination unit 80 determines whether or not the viewing environment satisfies the group viewing condition according to the group viewing branch. If the determination is affirmative, the process proceeds to step 202, and if the determination is negative, the process proceeds to step .

[0113] In step 202, the distribution moving image selection unit 44 selects group moving image data in accordance with the group viewing branch, and the process proceeds to step .

[0114] As described above, the group viewing video distribution process according to this embodiment distributes group video data when the viewing environment of the mobile terminal 3 satisfies the group viewing conditions. Therefore, since it becomes necessary for users to communicate with each other in order to satisfy the group viewing conditions, the group viewing video distribution process can encourage users to watch videos while communicating with each other.
