FIG. 5 shows the functional configuration realized by each device. The server device 10 includes an acquisition unit 101 , an instruction reception unit 102 , a player identification unit 103 , a counting unit 104 and a video distribution unit 105 . Camera 20 includes photographing unit 201 , measuring unit 202 , input accepting unit 203 , and transmitting unit 204 . Note that each of the plurality of cameras 20 shown in FIG. 1 includes each unit shown in FIG. The display device 30 includes an operation reception section 301 and an image display section 302 .

A photographing unit 201 of the camera 20 has a function of photographing an image. In this embodiment, the cameraman has decided on the player to be photographed, and is instructed to continue photographing the player from at least the 1st hole to the end of the 18th hole. (may include practice area and post-hole out interviews). As a result, the photographing unit 201 continuously photographs a specific player among the plurality of players playing golf. The photographing unit 201 performs supply processing for supplying image data indicating the photographed image and photographing time to the transmitting unit 204 in parallel with the photographing processing.

The measurement unit 202 measures a value related to the playing situation of the player photographed by the photographing unit 201 . Specifically, the measurement unit 202 repeatedly measures the above-described camera position and camera direction at regular time intervals (for example, every second). As described above, the cameraman takes pictures while moving with the player to be photographed. It is assumed that the cameraman is instructed to keep the distance between himself and the player (hereinafter referred to as "shooting distance") substantially constant when moving.

As the shooting distance, a distance (approximately 5 to 10 m) that is as short as possible and does not interfere with the player's shot is determined. By keeping the shooting distance constant, it is possible to calculate the player's playing position (playing position) from the camera position and camera direction. Also, when the player hits the ball (at the time of the shot), the cameraman is instructed to stand behind the player who is about to hit the ball and shoot an image.

FIG. 6 shows an example of an image from behind player P1 at address. Player P1 is a right-handed hitter and is addressing to hit the ball in the flight line direction A1. The cameraman determines the direction of the flying line A1 from the line connecting the shoulders of player P1, the line connecting both feet, the direction of the club face, etc., and stands on the side opposite to the direction of the flying line A1 of player P1. shoot video.

FIG. 7 shows an example of the positional relationship between the camera 20 and the player P1. In the example of FIG. 7, the camera 20, which is separated from the player P1 at the time of the shot by the shooting distance L1, captures the image of the flight line direction A1. By directing the camera 20 from behind the player P1 toward the flight line direction A1, the direction in which the player wants to hit the ball is represented by the camera direction. The measurement unit 202 performs supply processing for supplying measurement data indicating the measurement results of the camera position and camera direction and the measurement time to the transmission unit 204 in parallel with the measurement processing.

Also, it is assumed that the cameraman is instructed to perform a specific operation on the camera 20 when the player is in a specific state. Specific states include, for example, a state of preparing for a shot (preparation state) in which the player arrives at the ball position and confirms the lie of the ball, the direction of launch, the number of the club, etc. (preparation state), the state of entering address (hitting state), A state in which the shot is completed and the player has started walking (moving state). The state of waiting for another player's shot is included in the ready state.

The input receiving unit 203 receives an operation indicating that the player to be photographed has entered a specific state such as a hitting state. The input device 27 of the camera 20 has buttons (preparation button, batting button, move button) corresponding to each state. For example, when the preparation button is pressed, the input reception unit 203 supplies the transmission unit 204 with state data indicating that the player to be photographed is ready for a shot and the current time. As described above, the transmission unit 204 is supplied with video data, measurement data, and state data.

The transmission unit 204 adds a camera ID (Identification) for identifying the own camera to the data supplied from each unit, and transmits the data to the server device 10 as player data regarding the player to be photographed. In the video distribution system 1, the player ID of each player is determined, and a shooting target table in which the camera ID of the camera 20 for shooting the player is associated with the player ID of the player is stored in the server device 10. there is

FIG. 8 shows an example of an imaging target table. In the shooting target table shown in FIG. 8, player IDs "P001", "P002" and "P003" are associated with camera IDs "C001", "C002" and "C003", respectively. Note that each ID is just an example, and it is not necessary to associate IDs with the same number. Alternatively, instead of the player ID, for example, the player name may be directly associated with the camera ID.

The acquisition unit 101 of the server device 10 acquires a plurality of player data transmitted from each of the cameras 20 . The acquiring unit 101 acquires a video represented by player data, that is, a video continuously photographing a specific player in a sport such as golf in which a plurality of players compete at the same time. Acquisition unit 101 is an example of the “acquisition unit” of the present invention. The specific player here is the player whose player ID is associated in the shooting target table with the camera ID indicated by the player data, that is, the player whose camera 20 with that camera ID is the shooting target.

The operation accepting unit 301 of the display device 30 accepts an operation related to video distribution. The operation reception unit 301 receives, for example, a start operation for instructing the start of video distribution, and transmits operation data indicating the received operation and the device ID of its own device to the server device 10 . The instruction receiving unit 102 of the server device 10 receives an instruction corresponding to the operation indicated by the transmitted operation data as an instruction regarding video distribution. For example, when the operation data indicates a distribution start operation, the instruction receiving unit 102 receives a distribution start instruction as an instruction corresponding to the start operation.

Upon receiving the distribution start instruction, the instruction reception unit 102 supplies the player identification unit 103 with the device ID of the display device 30 that has issued the start instruction. Player data acquired also from the acquisition unit 101 is supplied to the player identification unit 103 . The player specifying unit 103 specifies a player to be distributed to the display device 30 from among the players whose images are indicated by the supplied player data. At the start of video distribution, the player specifying unit 103 specifies, as a player to be distributed, a player who satisfies a start time condition determined for specifying a player to be displayed at the start of distribution, for example.

The player identification unit 103 determines, for example, that the player with the highest ranking among the players currently playing satisfies the condition at the start. Golf is a sport in which the intermediate progress of each player's ranking is indicated during the game, and the ranking is indicated by the score (number of strokes) of each player. The tallying unit 104 tallies the scores of each player. In the golf relay, volunteers called scorers accompany the players in each group, count the scores of each player for each shot, and report to the relay headquarters.

When the person in charge of the relay headquarters receives the report of the score, he/she enters the score of each player into the score input terminal prepared at the headquarters. The terminal for score input transmits score data indicating the input score, the hole played, and the player ID to the server device 10 . The tallying unit 104 sums the score of each hole indicated by the transmitted score data for each player, and generates tally data indicating the total score, the hole being played, the ranking, and the player ID for each player.

When the device ID is supplied from the instruction receiving unit 102, that is, when the display device 30 instructs the player specifying unit 103 to start distributing the video, the player specifying unit 103 refers to the tally data generated by the tally unit 104, and determines the current ranking. The player with the best score, ie, the player who meets the starting conditions, is identified as the first player to be delivered. If there are multiple players with the highest score, the player specifying unit 103 may specify, for example, the player who completed the most number of holes as the player to be distributed.

Also, if the number of holes completed by the player with the highest score is the same, the player identification unit 103 compares the scores of the latest holes, for example, and ranks the player with the smaller number of strokes higher. The remaining player may be identified as the first player to be streamed, going back until the two holes before are settled. The player identification unit 103 supplies the video distribution unit 105 with the player ID of the identified player to be distributed and the device ID of the display device 30 that instructed to start video distribution.

When the player ID and the device ID are supplied, the video distribution unit 105 acquires player data indicating the supplied player ID from the acquisition unit 101 and acquires tally data representing the supplied player ID from the tally unit 104. . The video distribution unit 105 distributes the video data of the player with the player ID supplied from the player identification unit 103 among the video data of the player indicated by the player data supplied from the acquisition unit 101 . It is transmitted to the display device 30 of the device ID.

In addition, the video distribution unit 105 adds the player's name indicated by the obtained tally data, the information of the hole being played, the score, and the image indicating the ranking to the video of the player, and then transmits the video data. . By transmitting the video data as described above, the video distribution unit 105 transmits the video of the target player identified from the plurality of players by the player identification unit 103 to the display device 30 that has instructed to start video distribution. Distribute (display the video of the player on the display device 30).

The video display unit 302 of the display device 30 displays the video distributed from the server device 10 on the display surface 351 of its own device.
FIG. 9 shows an example of an image displayed on the display surface 351. As shown in FIG. In the example of FIG. 9, the video display unit 302 displays the video of player G playing, the information of the hole being played (“7”=number of holes, “Par4”, “465 yards”), and the score of player G ( “-2”) and a play image B1 indicating the ranking (“Leader”=tournament leader) are displayed.

After the video distribution is started as described above, the operation receiving unit 301 receives, for example, an end operation for instructing the end of the distribution. When the distribution end operation is accepted, the instruction reception unit 102 of the server device 10 receives the distribution end instruction, and the video distribution unit 105 ends the distribution. Next, video switching in the above-described manual switching mode and automatic switching mode will be described.

FIG. 10 shows an example of operations related to video switching. In FIG. 10, a leftward operation C1, a rightward operation C2, an upward operation C3, a downward operation C4, and two consecutive operations C5 (such as a double tap) are shown as examples of switching operations. For example, in the case of a remote controller operation, the operation reception unit 301 performs operations C1 (left button), C2 (right button), C3 (up button), and C4 for the left and right buttons and the up and down buttons provided on the remote controller. (down button), and an operation of pressing a predetermined button twice in succession is accepted as an operation C5.

Further, the operation accepting unit 301 accepts leftward, rightward, upward, and downward flick operations as operations C1, C2, C3, and C4, respectively, and accepts a double tap as operation C5, if the operation is performed on the touch screen. The operation accepting unit 301 transmits operation data indicating the accepted operation to the server device 10 . In this embodiment, when the transmitted operation data represents the operation C5, the instruction receiving unit 102 of the server device 10 receives the instruction to switch between the manual switching mode and the automatic switching mode.

In the state of the manual switching mode, the instruction accepting unit 102 accepts the operations C1 to C4 as instructions for switching the video, and supplies the received operation data to the player specifying unit 103 . In the manual switching mode, the player identification unit 103 identifies the player to be displayed according to the operation indicated by the supplied operation data. For example, the player specifying unit 103 specifies players in the same group as players to be displayed in the case of left and right operations, and specifies players in a different group as players to be displayed in the case of up and down operations.

Further, in the state of the automatic switching mode, the player identification unit 103 identifies, as a player to be displayed, an image of a player who satisfies a predetermined display condition when a predetermined switching condition is satisfied. The switching condition is met, for example, when the player being displayed is in a predetermined state. The predetermined state is, for example, a moving state. In this case, the player identification unit 103 determines that the switching condition is satisfied when the player being displayed is in a moving state, that is, when the shot ends.

When determining that the switching condition is satisfied, the player identification unit 103 determines whether or not there is a player who satisfies the display condition for each player not displayed. For example, the player identification unit 103 determines that a player whose ranking in the game satisfies a predetermined ranking condition satisfies the display condition. The ranking condition is, for example, a condition that is satisfied by rankings within a predetermined range (within the top 10, etc.) of the top ranks of the tournament. In addition, for example, in the qualifying round, the order before and after the cut line may satisfy the order conditions.

In addition, in a game in which the right to participate in another game is on the line, the order in which the right to participate may be obtained satisfies the ranking conditions. In short, it is sufficient that the order expected to attract viewers' attention satisfies the order condition. Note that, when a plurality of players meet the ranking conditions, the player specifying unit 103 uses the same method (comparison of the number of holes completed and the score of the latest hole) to determine the players meeting the conditions at the start, for example, as described above. should be specified.

By distributing the video specified as described above, the video distribution unit 105 distributes the video displayed on the display surface 351 of the display device 30 according to the predetermined display condition when the above-described predetermined switching condition is satisfied. Switch to the image of the player who satisfies Specifically, the video distribution unit 105 switches the video displayed on the display device 30 to the video of the player whose ranking satisfies the predetermined ranking condition as the video of the player who satisfies the predetermined display condition. The display surface 351 is an example of the "display area" of the present invention, and the video distribution unit 105 is an example of the "display control unit" of the present invention.

Each device included in the video distribution system 1 performs distribution processing for distributing the video of the athlete based on the above configuration.
FIG. 11 shows an example of the operation procedure of each device in the distribution process. Although only one camera 20 is shown in FIG. 11, the other cameras 20 are assumed to perform the same operation. The operation procedure shown in FIG. 11 is started, for example, when a sports broadcast starts.

First, the camera 20 (image capturing unit 201) captures an image of the player (step S11). Next, the camera 20 (measuring unit 202) measures the camera position and the like (step S12). Subsequently, the camera 20 (input receiving unit 203) receives an operation indicating that the player to be photographed is in a specific state such as a hitting state (step S13). Then, the camera 20 (transmitting unit 204) transmits to the server device 10 the player data obtained by adding the camera ID to the data acquired in the operations from steps S11 to S13 (step S14).

Operations from steps S<b>11 to S<b>14 are repeatedly performed by a plurality of cameras 20 . Note that the order of operations from steps S11 to S13 may be different. The server device 10 (acquisition unit 101) acquires the images indicated by the player data respectively transmitted from the plurality of cameras 20 as images of a specific player continuously shot (step S15). Here, it is assumed that the display device 30 issues an instruction to start distributing video.

First, the server device 10 (athlete identification unit 103) identifies the first athlete to be distributed (athlete who satisfies the conditions at the start) from the athletes whose images have been acquired (step S21). Next, the server device 10 (video distribution unit 105) transmits the video data of the specified player to the display device 30 that has instructed to start distribution (step S22). The display device 30 (image display unit 302) displays the image of the player indicated by the transmitted image data on the display surface 351 of its own device (step S23).

In the example of FIG. 11, it is assumed that the manual switching mode is in operation at the start of distribution. Here, it is assumed that a mode switching operation has been performed on the display device 30 . The display device 30 (operation reception unit 301) receives a mode switching operation (step S31), and transmits operation data indicating the received switching operation to the server device 10 (step S32). The server device 10 (player identification unit 103) determines that the switching operation indicated by the transmitted operation data has switched to the automatic switching mode, and starts operation in the automatic switching mode (step S33).

The server device 10 (player identification unit 103) first determines whether or not a predetermined switching condition is satisfied (step S41). If the server device 10 (player identification unit 103) determines that the switching condition is not satisfied (NO), step S41 is repeated. When determining that the switching condition is satisfied (YES), the server device 10 (player identification unit 103) identifies a player who satisfies the display condition (step S42).

Next, the server device 10 (video distribution unit 105) transmits the specified video data of the player to the display device 30 (step S43). The display device 30 (image display unit 302) switches the image of the player displayed on the display surface 351 of its own device to the image of the player indicated by the transmitted image data (step S44). During the automatic switching mode, the operations from steps S41 to S44 are repeated.

In this embodiment, as described above, when the switching condition is satisfied, the video of each player can be automatically switched and displayed. Also, in this embodiment, the player to be switched is specified based on the ranking within the competition. As a result, for example, players in specific rankings (higher ranks, before and after the cut line, or before and after the rankings in which the right to participate in a specific match is given) are displayed in succession, and compared to the case where the ranking condition is not used, the It is possible to make it easier to grasp the playing situation of the player of a specific ranking.

[2] Modifications The embodiment described above is merely an example of implementation of the present invention, and may be modified as follows. Moreover, the embodiment and each modification may be combined as necessary. In that case, each modification may be implemented with an order of priority (by prioritizing which one should be prioritized when a competing event occurs when implementing each modification).

[2-1] Position of player In the embodiment, the position of the player was calculated from the camera position and camera direction. may be used as the position of the player as it is.

If it is difficult to keep the shooting distance constant, the shooting distance may be calculated from the player's video. In this case, for example, the player identification unit 103 stores the height data of each player in advance, and recognizes the appearance of the player from the acquired video using pattern recognition technology or machine learning technology. Then, the player identification unit 103 calculates the distance to the player, that is, the shooting distance from the size of the recognized player in the image and the actual height, and calculates the position of the player using the calculated shooting distance.

[2-2] Athlete in specific state In the embodiment, when a specific operation is performed on the camera 20, the player enters a specific state (preparation state, batting state, and movement state). However, instead, it may be determined from the video of the player that the player has entered a specific state. For example, the player identification unit 103 stores in advance data indicating a person's movement in a specific state.

Then, the player identification unit 103 recognizes the figure of the player from the acquired image using pattern recognition technology or the like, and the similarity between the movement indicated by the recognized figure and the movement of the person in the specific state reaches or exceeds a threshold. Athletes are considered to be in a particular condition if Note that even if there is no data indicating a person's movement, the player identifying unit 103 can determine a player in a specific state by learning features of the player's video in a specific state using machine learning technology. may

[2-3] Sports The video distribution system 1 may distribute, for example, marathons, relay races, bicycle races, automobile races, sailing, etc., in addition to golf. All marathons and the like are sports in which a plurality of athletes compete at the same time. Also, for example, even in a rally where each competitor does not start all at once and each individual time attack, if it is a sport in which multiple competitors run on the course at the same time, the displayed competitors will be automatically displayed. You can watch various players by switching between them.

In competitions such as rally and sailing where it is difficult for a cameraman to get close to the athletes, the images may be taken remotely from a helicopter or the like, or the images may be taken with a drone tracking them. In any case, if the shooting distance is determined, the player's position can be obtained from the camera position and camera direction. Note that, as described above, the player's position may be calculated by calculating the photographing distance based on the size of the equipment in the image and the actual size. Alternatively, instead of the state data, the acquisition unit 101 may acquire measured values obtained by a positioning device installed in an automobile, a yacht, or the like, and the player's position may be obtained.

[2-4] Variation of Ranking Conditions The ranking conditions described in the embodiment may be changed according to the progress from the start to the end of the competition. In this modified example, the player identification unit 103 changes the ranking condition according to the progress of the competition from start to finish, and identifies the video of the athlete whose ranking satisfies the changed ranking condition as the player to be displayed.

For example, on the first day and the second day of the tournament, the player identification unit 103 determines that the rankings before and after the cut line satisfy the ranking conditions, and on the third day, the rankings that change significantly on the day (for example, rankings that have changed by 20th or more) satisfy the ranking conditions. , on the final day, it is judged that the ranking within the top 10 satisfies the ranking conditions. By distributing the specified video as described above, the video distribution unit 105 displays the videos of the athletes whose rankings satisfy the ranking conditions, which fluctuate according to the progress from the start to the end of the competition. As a video, video switching is performed.

Note that the method of changing the ranking condition according to the progress is not limited to the above method. For example, in a bicycle road race, until the escape is decided, the order of the runners who are fighting from the top satisfies the ranking conditions. The ranking of the competitors within the main group fulfills the ranking requirements. In any case, according to this modified example, when the ranking to be noticed changes according to the progress of the competition, the athletes of the ranking to be noticed throughout the competition are displayed compared to the case where the ranking condition is fixed. can be made easier.

[2-5] Viewing tendency Display conditions different from the embodiment may be used. In this modified example, a display condition is used whose sufficiency is determined based on the viewer's viewing tendency. The player identification unit 103 of this modification determines the possibility that a user (that is, a viewer) viewing the video displayed on the display surface 351 of the display device 30 will view the video of the player when the switching condition is satisfied. Height is determined for each player. The player identification unit 103 is an example of the "player determination unit" of the present invention.

The player identification unit 103 determines the likelihood that the user will watch the video of the player based on the information about the user. The player identification unit 103 makes determination using, for example, the viewing history of the user using the display device 30 as information about the user. When the video distribution unit 105 distributes the video to the display device 30, the video distribution unit 105 stores information about the distributed video as a distribution history. The delivery history includes the player ID of the player appearing in the video, the device ID of the delivery destination display device 30, and the delivery time.

The player identification unit 103 refers to the distribution history and calculates the total distribution time of the player IDs associated with the device IDs of the display devices 30 that distribute the video. The player identification unit 103 determines a player who is likely to be viewed by the user in order from the player with the longest calculated total time. Note that the player identification unit 103 may determine a player who is highly likely to be viewed by the user in order from the player with the highest viewing count.

The player identification unit 103 may indicate the viewing possibility determination result in terms of the ranking indicating the level of the viewing possibility, or in a value obtained from the viewing time or the number of times of viewing. The player identification unit 103 identifies a player who satisfies the display condition by using the display condition whose satisfaction is determined based on the determined viewing possibility. When the viewability is indicated by ranking, the player identification unit 103 identifies, for example, a player with a determined viewability equal to or higher than a predetermined rank as a player who satisfies the display condition.

Further, when the viewability is indicated by a value, the player identification unit 103 identifies a player whose determined viewability is greater than or equal to a threshold value or less than the threshold value as a player who satisfies the display condition. If there are multiple players who meet the display conditions, the player specifying unit 103 specifies the players who meet the display conditions, for example, in the same manner as the determination of the players meeting the conditions at the start described above (comparing the number of holes completed and the score of the latest hole). do it. In addition, the player identification unit 103 may specify a player who satisfies the display condition with priority given to a player with a higher viewing possibility.

By switching to the video of the player specified as described above, the video distribution unit 105 changes the video displayed on the display surface 351 of the display device 30 to the video of the player whose high viewing possibility meets the display conditions. Switch to video. It can be said that the player who is more likely to be watched by the user is the player that the user likes. In this modified example, the video is switched in accordance with the above-described priority order, so that the user can continuously watch his or her favorite players.

Note that the viewing possibility determination method is not limited to the above method. For example, when the user also plays sports, the player identification unit 103 may determine the viewability of each player based on the degree to which the attributes as a player are common to the user. Attributes as an athlete are attributes that represent personal physical characteristics such as height, weight, and origin (country, region, school, etc.) or a career from which competition experience can be inferred.

Attributes as a player also include sports play style. For example, in the case of golf, the playing style is a fade hitter, a draw hitter, a long hitter, a shot maker, a good putt player, and the like. In this case, the player identification unit 103 uses, for example, information indicating attributes of the user as an athlete registered by the user and stored in the server device 10 as information related to the user.

Also, the server device 10 stores attributes of each player registered by the system operator in association with the player ID, for example. When the switching condition is satisfied, the player identification unit 103 reads the attributes stored in association with the player ID of the player being displayed, and calculates the number of attributes common to the user among the read attributes for each player. Count. The player identification unit 103 determines the viewing possibility according to the number of common attributes, that is, the degree of commonality between the attributes and the user.

For example, the player identification unit 103 determines that a player having a large number of common attributes, that is, a player having a high degree of commonality with the user in terms of attributes, is a player with a high viewing possibility. For viewers, it is easier for viewers to feel a sense of familiarity and empathy with a player whose attributes are more similar to themselves. In addition, the closer the attributes as a player are, the easier it is to refer to one's own play. By determining the viewing possibility based on the attributes of the player as described above, the viewer can continuously watch the players with whom the viewer can easily empathize and who can serve as a reference for their play.

Note that some viewers may want to watch the play of a player whose attributes are different from theirs because it is more stimulating. Therefore, the player identification unit 103 may determine that a player with a smaller number of common attributes, that is, a player with a lower commonality of attributes with the user, is a player with a higher viewing possibility. In that case, the viewer can continuously watch players whose attributes are different from those of themselves and who are stimulating.

Further, the player identification unit 103 may determine that the player who advances the game in the game area at a specific degree of progress (for example, the last group and the group before that) is more likely to be watched. In addition, the player identification unit 103 assigns points to each player's in-game ranking, viewing history, common attribute, and degree of progress, and determines that the higher the total number of points assigned to the player, the more likely the player will be viewed. good too. At that time, each point may be weighted.

[2-6] Specific Situation Display conditions different from the embodiment may be used. In this modification, for example, it is assumed that a player in a specific situation satisfies the display condition. The player identification unit 103 of this modified example identifies a player in a specific situation from among the players who are playing. The player identification unit 103 identifies, for example, a player who is in a specific situation of playing as a player in a specific situation.

Specific plays include, for example, tee shots, shots aimed at the green, approach shots, bunker shots, shots over water, intentional slice shots, intentional hook shots, and long putts. For example, the player identification unit 103 identifies a player whose distance from the tee ground is within a threshold value among the players in the preparation state and the ball-hitting state as the player who will take the tee shot.

In addition, the player identification unit 103 identifies a player who is in a position in the bunker among the players in the preparation state or the batted ball state as a player who performs a bunker shot. In addition, the player identification unit 103 identifies a player who is on the green and whose distance to the hole is equal to or greater than a threshold value (for example, 10 m or longer) from among the players in the batting state as a player who makes a long putt. Players in the ready state are often near the hole, and it is difficult to judge whether it is a long putt or not, so players in the ready state are excluded.

In addition, the player identification unit 103 identifies a player whose distance from the green is within a predetermined range (for example, 50 yards to 250 yards) from among the players in the preparation state and the batting state as a player who makes a shot at the green. In addition, the player identification unit 103 identifies a player who is in a predetermined area in front of the pond among the players in the preparation state and the batted ball state as a player who makes a shot over the pond.

In addition, the player identification unit 103 performs an intentional slice shot (on the right side of the fairway) or an intentional hook shot (on the right side of the fairway) for a player who is in a predetermined area in front of a tree in the hole, among the players in the preparation state and the ball-hitting state. to the left of the fairway). In this modification, the broadcaster or the like selects in advance the type of player's situation (play) that the viewer is recommended to view, and causes the server device 10 to store information indicating the type of player's situation (play) selected. Keep

When the switching condition is satisfied, the player identifying unit 103 determines, for example, that a player who is in a specific play situation at that time satisfies the display condition. Incidentally, the broadcaster may determine the priority of the types of player situations (plays) that the viewers are recommended to watch. In this case, if the player with the first priority is not specified, the player specifying unit 103 determines the player with the second priority (if the second is not specified, the third player). satisfies the display conditions.

By switching to the video of the player specified as described above, the video distribution unit 105 switches the video from the video of the player in the specific situation to the video of the player who satisfies the display conditions. In this modification, for example, by registering the situation (play) of a specific player as described above, compared to the case where the video is switched regardless of the situation of the player, the player in the specific situation (for example, the viewer It is possible to make it easy to view the video of a player who is in a situation to play that is recommended to watch).

It should be noted that the method of specifying a player in a specific situation is not limited to the above method. For example, the input reception unit 203 of the camera 20 receives an input of the type of player's situation, and the player identification unit 103 identifies a player in a specific situation based on the type of player's situation indicated by the state data. You may Also, when there is no input to the camera 20, a player in a specific situation can be specified as follows.

For example, the player identification unit 103 analyzes the image of the player and extracts the contour of the player. judge there is. Then, the player identification unit 103 identifies a player who is in a specific play situation in the same manner as the above method based on the position of the player when he hits the ball (for example, the player who hits the ball on the tee (identify as a player in a situation to take a tee shot).

Also, in a race such as a marathon, the player identification unit 103 identifies, for example, a player who is running alone or a player who is overtaking as a player in a specific situation. In a competition such as a rally, the player identifying unit 103 identifies, for example, a player running at maximum speed or a player running in a difficult section as a player in a specific situation. In addition, the player identification unit 103 identifies a player who is running alone, for example, based on the position of each player and the amount of positional change (that is, speed) per unit time.

As described above, the player identification unit 103 assumes that the spectator is in a situation where it can be identified based on the measurement value of the sensor of the camera 20, the measurement value of the sensor attached to the player, the cameraman's operation, etc., and the viewer's desire to watch the game. It is sufficient to identify the situation of the player who is being kicked as the specific situation. According to this modified example, it is possible to make it easier to view the video of the player in a specific situation, compared to the case where video switching is performed regardless of the player's situation.

It should be noted that the specific situations used to determine display conditions differ from sport to sport. For example, in a competition such as a marathon, specific situations are used such as a situation in which a player is fighting for the lead, a situation in which he is running alone, a situation in which he overtakes a previous player, and a situation in which his lap time has increased. Further, in competitions such as rallies, a situation in which the vehicle is traveling at maximum speed, a situation in which it is difficult to travel, or the like is used as a specific situation.

In these cases, the player identification unit 103 identifies a player in a specific situation, for example, based on the position of each player and the amount of positional change (that is, speed) per unit time. The player identification unit 103 identifies the situation of the player that can be identified based on the measured value of the sensor of the camera 20, the measured value of the sensor attached to the player, the operation of the cameraman, etc., and the viewer's desire to watch the game is assumed. The situation should be a specific situation. In either case, it is possible to show more videos of players who are likely to be viewed by the user, that is, videos of players who are in situations preferred by the user.

[2-7] Viewing tendency of play A player who is highly likely to be watched by a viewer (a user who watches a video displayed on the display surface 351 of the display device 30) is used as a player in a specific situation. good too. In this modified example, the player identification unit 103 determines a situation in which the viewer is likely to watch based on information related to the viewer. The player identification unit 103 is an example of the "situation determination unit" of the present invention.

For example, the viewer's viewing history is used as the viewer-related information. In that case, the player identification unit 103 identifies various situations in the video stored as the viewing history for each player. The various situations are situations in which various shots such as the above-described tee shot are taken. The player identification unit 103 counts the number of times of the identified situation or the duration of the situation for each type of situation, and determines that the larger the total value of the counted values, the more likely the viewer is to view the situation. .

For example, the player identification unit 103 determines whether the display condition is satisfied and identifies the player to be distributed, in the same manner as in the modified example above, using a situation in which the number of situations or the duration of the situation is equal to or greater than a threshold as a specific situation. By switching to the video of the player identified as described above, the video distribution unit 105 switches the video, with the player in the situation with a high possibility of being viewed determined by the player identification unit 103 as the player in the specific situation. I do.

It can be said that the situation in which the user is more likely to view the content is the situation that the user prefers. In this modification, by determining the situation with a high viewing possibility as described above, compared to the case where the play performed in a specific situation is fixed, each viewer video can be easily viewed. Note that the method for determining the situation in which the user is likely to view is not limited to the above method.

For example, the user registers in advance the type of situation that the user wants to see (that is, the situation that the user is likely to watch), and information indicating the type of situation registered by the server device 10 (an example of information related to the viewer). may be stored. In addition, the server device 10 may store information (an example of viewer-related information) indicating attributes of the user as a contestant registered by the user.

In this case, the player identification unit 103 determines that, for example, if the viewer has the attributes of a long hitter or a young generation such as in their twenties, there is a higher possibility that the driver shot is viewed rather than the approach shot. Then, it is determined that if the viewer has the attributes of a short hitter or a generation whose physical strength is declining, such as in their 60s, there is a higher possibility of viewing a situation in which an approach shot is performed rather than a driver shot.

[2-8] Video from the time when a specific situation occurs If a player who meets the display conditions is already in a specific situation (for example, already in a take-back), There are times when you want to watch from the point in time when a particular situation occurs. Therefore, in this modified example, the acquisition unit 101 accumulates the acquired video of the player as it is. The acquisition unit 101 in this case is an example of the "storage unit" of the present invention.

Then, the video distribution unit 105 switches the video accumulated in the acquisition unit 101 for the player who satisfies the display condition to the video at the time when the specific situation occurs. If a player is in a specific play situation and meets the display conditions, the player's current state is "preparation state" or "ball batting state" (because "moving state" is not included in a specific play). ). When reading out the video of the player specified as the distribution target, the video distribution unit 105 reads and distributes the video, for example, starting with the video taken at the latest "preparation state".

If there is a request that the image before entering the address is not required, the image distribution unit 105 reads out the latest image as it is if the current state is "preparation state", and if the current state is "ball hitting state". Only in the case of "ball hitting state", the video may be read out from the video taken at the "ball hitting state" and distributed. Also, the viewer may be allowed to select from which of the "preparation state" and "ball-hitting state" the distribution should start. According to this modified example, it is possible to see a player's specific situation (for example, a situation in which a specific play is made) from the beginning rather than from the middle.

[2-9] Switching Conditions Switching conditions different from those in the embodiment may be used. For example, in the embodiment, the switching condition is satisfied when the player being displayed is in a moving state, but the switching condition may be satisfied when the player being displayed is holed out. The switching condition may be satisfied when a predetermined period of time has elapsed since the state was entered.

Also, the switching condition may be satisfied when a player other than the player being displayed is in a predetermined state. For example, a switch condition may be met when a player not shown makes a particular play such as hole-in-one, albatross, or eagle. In that case, by setting the player who performed a specific play to also satisfy the display condition, it is possible to switch the video to that play as soon as the specific play is performed.

Since the above-mentioned specific play is known after the shot is finished, the video distribution unit 105 may switch to the video at the time when the specific play is started, as described in the modified example above. In addition, the switching condition may be satisfied when the ranking of the undisplayed player reaches a specific ranking (for example, 1st place). good.

Also, the switching condition may be satisfied regardless of the player's actions or play results. For example, the switching condition may be satisfied when a certain period of time has elapsed since the player's video started to be displayed. In short, a condition that is satisfied when a situation assumed as a trigger for the viewer to switch the video may be used as the switching condition. In particular, when the viewer wants to watch another video, it is possible to switch the video by using the break of the play and the performance of the outstanding play as a trigger.

[2-10] Video of Specific Player The video may be switched to follow the play of a specific player. In this modified example, when a specific player is in a specific situation, the video distribution unit 105 first displays the video of the player as a player who satisfies the switching condition and the display condition. switch.

A specific player is, for example, a player registered in advance by a viewer. Note that the specific player may be a player with a high viewing possibility as described in the modified example above, or may be a player with a high commonality of attributes with the viewer. A particular situation is, for example, the situation of taking a general shot (all shots from tee shot to putt). Further, when switching to the video of a specific player, the video distribution unit 105 may switch to the video at the time when a specific situation occurs.

Then, when the specific situation of the specific player ends, the video distribution unit 105 switches the video assuming that the switching condition is satisfied. In this case, the video delivery unit 105 switches to the video of the player who satisfies the display conditions when the specific situation ends, as in the embodiment. After the video is switched, when the specific player is in the specific situation again, the video is switched to the video of the specific player. In this modified example, it is possible to watch all videos in which a specific player is in a specific situation, and to watch videos of other players during a period when the specific situation is not occurring. there is

[2-11] Switching after the play ends For example, if the switching condition is satisfied when a player other than the player being displayed is in a predetermined state, the video may switch even if the player being displayed is still playing. be. Therefore, if the switching condition is satisfied, the video distribution unit 105 may switch the video after the player being displayed finishes playing.

The play here may include, for example, not only the play currently being performed by the displayed player, but also the play that the player is about to perform. In this case, the video distribution unit 105 does not perform switching even if the switching condition is satisfied while the player being displayed is in the preparation state or batting state, and performs switching when the player is in the moving state. As a result, even if the player being displayed is ready for the tee shot, the image is switched after the tee shot is finished.

For viewers who do not need to watch the video of the preparation state, the play that the player is about to make may not be included in the video being displayed. In this case, the video distribution unit 105 does not switch during the ball hitting state, but performs switching during the preparatory state. Regardless of how the range of "play" is defined, according to this modified example, the viewer can view the current play of the displayed player to the end.

[2-12] Combination The player identification unit 103 may determine whether or not the display condition is satisfied by combining the ranking condition, the viewer's viewing tendency, and the presence or absence of a specific situation. For example, the player identification unit 103 gives each player a point according to the ranking, a point according to the high viewing possibility, and a point according to the presence or absence of a specific situation, and totals them. Satisfaction of display conditions is determined based on points.

Specifically, the player identification unit 103 determines that the display condition is met when the total points are equal to or greater than a threshold, or determines that the player with the highest total point satisfies the display condition. Note that each point may be weighted. In short, the player identification unit 103 displays the player whose order in the game is in a specific order, the player who is highly likely to be viewed, or the player who is in a specific situation, so that they are displayed more easily than other players. It suffices to determine whether the conditions are satisfied.

[2-13] Number of Cameras In the embodiment, one camera 20 is attached to each player during play to shoot images. or random players may be selected and photographed. Also, if the number of cameras 20 is greater than the number of players, two or more cameras 20 may be attached to one player to capture images. In that case, any one of two or more videos of one player may be distributed.

In addition, in the video distribution system 1, since the images of the athletes are switched, it is necessary to shoot the images of at least two athletes. Even with images of two players, it is possible to switch automatically according to the situation of the players. However, if there are two players, the players that appear in the switched video will be determined, so it is more desirable to shoot videos of three or more players.

[2-14] Correspondence between cameras and athletes In the embodiment, one camera 20 and one athlete are associated as shown in the shooting target table shown in FIG. of cameras 20 may be associated. Specifically, one may show the player and the other may show the ball hit by the player. Also, if the number of cameras 20 is less than the number of players in play, two or more players may be associated with one camera 20, and the players of the same group may be photographed in order, for example.

Also, the cameras 20 associated with the players may be changed during the round, and the number of cameras 20 associated with the players may be changed during the round. Specifically, for example, the first nine holes may be photographed by one camera 20 for two players, and the latter nine holes may be photographed by one camera 20 for one player. In either case, it suffices that each player, the hole to be played, and the camera 20 are associated with each other by means of a photographing target table or the like.

[2-15] Conditions at Start In the embodiment, the player with the highest ranking among the players currently playing satisfies the condition at start, but the condition at start is not limited to this. For example, tournament organizers or viewers may predefine player priorities, and the player with the highest priority among players in play may meet the starting conditions. Also, the player who completed the most holes or the player who took the least number of strokes (who just started) among the players who are playing may satisfy the condition at the start. Also, a condition for switching displayed players, which will be described later, may be used as a condition for starting.

[2-16] Device for realizing each function The device for realizing each function shown in FIG. 5 is not limited to the devices described above. For example, an external device may implement some of the functions implemented by the server device 10 (such as the player identification unit 103 and the tallying unit 104). Both the server device 10 and the external device may be computer resources provided by a cloud service.

Also, for example, in the embodiment, the player specifying unit 103 determines both the switching condition and the display condition, but each condition may be determined by another function. Further, the identification of the player by the player identification unit 103 and the distribution of the video by the video distribution unit 105 may be performed by one function. In short, as long as the functions shown in FIG. 5 are realized in the video distribution system 1 as a whole, and the player's video is distributed, the functional assignment of each device and the range of actions performed by each function can be freely determined. can be
