     DESCRIPTION OF EMBODIMENTS 
       [0032]    One aspect of the present disclosure has an object to display appropriate information according to the attribute of the player. 
         [0033]    Hereinafter, an embodiment according to the present disclosure is described in detail with reference to the accompanying drawings. The embodiment is described by taking as an example a case where a retrieval target video image is a baseball game video image. 
         [0034]    As illustrated in  FIG. 1 , a display controller  10  according to the embodiment is coupled with a distribution server  20  configured to distribute a baseball game video image via a network or the like, and performs display control when a video image acquired from the distribution server  20  is reproduced by a display device  84 . 
         [0035]    The distribution server  20  stores a video image file  21  indicating video images of captured baseball games. In the embodiment, one video image file  21  is provided for each game. Each video image file  21  is managed in a uniquely identifiable manner such that the video image file  21  is assigned with a file name using the game date and the playing teams in the game recorded in the video image file  21 . For example, a video image file  21  of a game between Team A and Team B held on Apr. 10, 2016 may be assigned with a file name such as “20160410AB”. 
         [0036]    Each video image file  21  is a video image captured at a frame rate of, for example, such as 30 fps or 60 fps, and includes multiple frames. Each frame is associated with a frame time represented by a time elapsed since the start of capturing, and the frame time is used as identification information of each frame. 
         [0037]    In the video image file  21 , a section indicating a segment in the play is assigned with information indicating the segment in the play. In the embodiment, with every pitch of the pitcher is set as a segment of the play, and a “pitch tag” is assigned at a section indicating the start of the pitch by the pitcher. More specifically, the pitch tag is assigned, for example, to a frame at a predetermined time before (for example, 3 seconds before) the start of the pitching motion of the pitcher among frames included in the video image file  21 . 
         [0038]    The distribution server  20  stores a related information database (DB)  22  in which various information related to the video image file  21  is stored. In the embodiment, the related information DB  22  includes a player information table, an inter-user correspondence information table, a pitching meta data table, a result information table, and a game information table. The related information DB  22  also may include other information related to the video image file  21 . Hereinafter, tables of the related information DB  22  are described. 
         [0039]    The player information table is a table in which player information being information of each player is stored.  FIG. 2  illustrates an example of a player information table  23 . In the example of  FIG. 2 , each row (each record) indicates player information for one player. Each record of player information includes information such as “player ID” for uniquely identifying the player, “player&#39;s name”, “team” which is the team name of a team to which the player belongs, “position”, “uniform number”, “pitching/batting method”, and “picture”. “Position” is information from which at least the player is identifiable as a pitcher or a fielder. For the fielder, the infielder or the outfielder may be used as identifiable information, or more specific position such as the catcher, first baseman, and left fielder may be used as identifiable information. “Pitching/batting method” is information indicating, when the player is a pitcher, whether the player is right-handed or left-handed for pitching, and, when the player is a fielder, information indicating whether the player is right-handed (right batter&#39;s box) or left-handed (left batter&#39;s box) for batting. “Picture” is image data such as a face photograph of the player. 
         [0040]    The inter-user correspondence information table is a table which stores information indicating a correspondence relationship among users utilizing the application provided by the embodiment. The correspondence relationship among users in the embodiment is, for example, an association among users such as a relationship between a follow and a follower in Twitter (registered trademark). Although described in detail below, when information for the log-in user is provided on the top page displayed first when the user logs in this application, information related to the user whom the log-in user follows is also provided. 
         [0041]      FIG. 3  illustrates an example of an inter-user correspondence information table  24 . In the example of  FIG. 3 , the user ID of a user whom a user represented by the user ID follows is stored for each of user IDs by associating as “follow target user ID”. When the user utilizing the application is a player registered in the player information table  23 , the user ID is the player ID. 
         [0042]    The pitching meta data table is a table which stores pitching meta data being meta data of each pitch scene. Each pitch scene is represented, for each “pitch tag” assigned to the video image file  21 , by a group of frames starting from a frame to which the pitch tag is assigned and ending at a frame preceding a frame to which a next pitch tag is assigned. 
         [0043]      FIG. 4  illustrates an example of a pitching meta data table  25 . In the example of  FIG. 4 , each row (each record) indicates pitching meta data on the pitch scene of every pitch. In each record of pitching meta data, “file name” for identifying the video image file  21 , a frame time to which “pitch tag” is assigned, and information on the pitch scene starting from a frame to which the pitch tag is assigned are associated with each other. Information on the pitch scene includes information such as “game date”, “inning”, “fielding team”, “pitcher”, “batting team”, “batter”, “batting order”, “pitch result”, “at-bat result”, “pitching course”, “pitch type”, “hitting direction”, “count”, and “runner”. 
         [0044]    “Game date” is a date when a game including the pitch scene thereof is held. “Inning” is an inning (a top of the first inning, a bottom of the first inning, a top of the second inning, etc.) at the time of a pitch presented in the pitch scene. “Fielding team” is a team to which a pitcher performing the pitch indicated by the pitch scene belongs, and “pitcher” is information such as the player ID and player&#39;s name for identifying the pitcher. “batting team” is a team to which a batter at the time of the pitch presented in the pitch scene belongs, and “batter” is information such as the player ID and player&#39;s name for identifying the batter. “Batting order” is a batting order ( 1 ,  2 , . . . ,  9 ) of batters at the time of the pitch presented in the pitch scene. 
         [0045]    “Pitch result” is information indicating that result of the pitch in the pitch scene is strike or ball. The strike may be more specific information from which swing and miss, called strike or foul is identifiable. When a batter hits the pitched ball (except for the foul) or when the pitch is not judged as strike or ball, “pitch result” is left blank (in the example of  FIG. 4 , represented by “-”). 
         [0046]    “At-bat result” is a result of the at-bat assigned when a pitch indicated by the pitch scene is a last pitch in the at-bat including the pitch, such as, for example, hit, out or others. More specifically, the hit may be a single, a double, a triple, or a home run as identifiable information, and the out may be a single out, double play or strikeout as identifiable information. More specifically, the hit may be a result of combination of the hitting direction and the rise of hit ball such as a hit to a center and a fly to a right field. Others include, for example, four balls, hit by pitch, sacrifice bunt, sacrifice fly, error, fielder&#39;s choice, catcher&#39;s interference, fielder&#39;s interference, obstruction, and so on. When a pitch included in the pitch scene is not a last pitch in the at-bat including the pitch, “at-bat result” is left blank (in the example of  FIG. 4 , represented by “-”. 
         [0047]    “Pitching course” is a course (zone) where the pitched ball indicated by the pitch scene has passed. “Pitching course” may be represented by the number of the block where the pitched ball has passed through, for example, by dividing the strike zone and peripheral zones thereof into multiple blocks and assigning a number to each of the blocks as illustrated in  FIG. 5 . “Pitch type” is information indicating the pitch type of the pitch indicated by the pitch scene, such as, for example, straight, 2-seam, splitter, change-up, cutter, curve, slider, sinker, and other special types. “Hitting direction” is a direction of the ball hit by a batter against the pitched ball indicated by the pitch scene. “Hitting direction” may be represented by the symbol of the block where the hit ball has reached, for example, by dividing the ground into multiple blocks and assigning a symbol to each of the blocks as illustrated in  FIG. 6 . 
         [0048]    “Count” is the count of balls, strikes, and outs at the starting time of the pitch scene, represented in the format of “(ball count, strike count, out count)”. For example, 3 balls, 1 strike and 2 outs are represented by “(3, 1, 2)”. “Runner” indicates states of runners at the starting time of the pitch scene represented in the format of “(presence or absence of first runner, presence or absence of second runner, presence or absence of third runner). For example, presence of the runner is represented by “1” and absence of the runner is represented by “0”. Presence of the runner only on the first base is represented by “(1, 0, 0)”. 
         [0049]    The result information table is a table in which results depending on the states of each of players are stored. The result information table stores, for example, total results from the start of the season to the last game.  FIG. 7  illustrates an example of the result information table  26 . In the example of  FIG. 7 , various results for both the case where the player is a fielder and the case where the player is a pitcher are stored. 
         [0050]    In the case where the player is a fielder, “at-bat result breakdown”, “hitting direction breakdown”, “course-based batting average”, and “pitch type-based batting average” are stored. “At-bat result breakdown” is the ratios of hit and out per at-bat result, “hitting direction breakdown” is, for example, the number of hits in each of the hitting directions as illustrated in  FIG. 6 , “course-based batting average” is, for example, the batting average in each of the pitching courses as illustrated in  FIG. 5 , and “pitch type-based batting average” is the batting average in each of the pitch types. In the same manner, in the case where the player is a pitcher, “at-bat-based pitch result breakdown”, “course-based batted average”, and “pitch type-based batted average” are stored. In the case of the pitcher, the result is an at-bat-based pitch result or batted average. In the case where the player is a pitcher, runner state and “situation based batted average” indicating the ball count-based batted average are also stored as the result. Various results are not limited to those examples, and may include a batting average and a batted average for each of opponent teams, a batting average based on the throwing method of the pitcher (right-handed or left-handed), and a batted average based on the hitting method of the batter (right-handed hitting or left-handed hitting), and so on. Also, the result of the fielder may include the record of the situation-based batting average, and the result of the pitcher may include the hit direction breakdown. 
         [0051]    The game information table is a table in which game information indicating the overview of each game is stored.  FIG. 8  illustrates an example of the game information table  27 . In the example of  FIG. 8 , each row (each record) indicates game information for one game. Each row of game information includes information of “game date” when the game was held, “home team” and “visitor team” as playing teams in the game, and “home score” and “visitor score” indicating final scores of respective teams. The game information also includes information such as “inning-based score” indicating the score in each inning, and “winning pitcher” and “losing pitcher” in the game. Further, information such as the relief pitcher and the home run also may be included. 
         [0052]    The display controller  10  includes an acquisition unit  11  and a display control unit  12  in terms of the function. 
         [0053]    The acquisition unit  11  receives the user ID of the user who logs in the application provided by the embodiment and transmits the user ID to a distribution server  20 . The acquisition unit  11  acquires top page information transmitted from the distribution server  20  as information to be displayed on the top page displayed first after user&#39;s log-in. In the case where the user ID of the log-in user is a player ID, the top page information includes player information for the player ID, the player information being extracted from the player information table  23 . 
         [0054]    The top page information also includes a thumbnail image generated in any frame of a predetermined pitch scene included in the video image file  21 , and pitching meta data of the pitch scene. The predetermined pitch scene includes, for example, pitch scenes for last several games of the log-in user (player), pitch scenes for last several games of a user (player) whom the log-in user follows, and a pitch scene assigned with a message from the other user. Also, the top page information may include information not associated with the video image file  21 , for example, such as a meeting document. The acquisition unit  11  delivers the acquired top page information to the display control unit  12 . 
         [0055]    The acquisition unit  11  receives the retrieval condition of the video image from the log-in user, transmits the received retrieval condition to the distribution server  20 , and thereby requests distribution of the video image. Thus, the distribution server  20  identifies, with the received retrieval condition as a key, a pitch scene matching the retrieval condition out of the pitching meta data table  25 . Then, the distribution server  20  distributes a video image file  21  including the identified pitch scene and pitching meta data of the identified pitch scene to the display controller  10 . The acquisition unit  11  acquires the video image file  21  and pitching meta data distributed from the distribution server  20  and delivers the acquired video image file  21  and pitching meta data to the display control unit  12 . 
         [0056]    When the personal result screen (described below in detail) is selected by the log-in user, the acquisition unit  11  transmits the player ID of the player entered on the personal result screen to the distribution server  20  and thereby requests result information of the entered player. Then, the acquisition unit  11  acquires result information of the entered player which is extracted from the result information table  26  and transmitted from the distribution server  20 , and delivers the acquired result information to the display control unit  12 . 
         [0057]    When the game log screen (described below in detail) is selected by the log-in user, the acquisition unit  11  transmits the entered game date to the distribution server  20  and thereby requests game information of the entered game date for the team to which the log-in user belongs. Then, the acquisition unit  11  acquires game information of the entered game date which is extracted from the game information table  27  and transmitted from the distribution server  20 , and delivers the acquired game information to the display control unit  12 . 
         [0058]    The display control unit  12  controls screen display to a display device  84  based on information delivered from the acquisition unit  11  and operation of the log-in user. 
         [0059]    More specifically, upon receiving the top page information from the acquisition unit  11 , the display control unit  12  displays, for example, a top page screen  40  as illustrated in  FIG. 9  on the display device  84 . The top page screen  40  includes a top page tab  31  for switching the screen displayed on the display device  84 , a retrieval and reproduction tab  32 , a personal result tab  33 , and a game log tab  34 . The top page screen  40  is a screen in a state where the top page tab  31  is selected. The top page screen  40  includes a log-in user display area  41 , a recent at-bat display area  42 , and a time line display area  43 . 
         [0060]    The display control unit  12  displays, based on the player information of the log-in user delivered from the acquisition unit  11 , player&#39;s name, team, position, uniform number, throwing method or hitting method, and picture of the log-in user, in the log-in user display area  41 . In the case where the log-in user is not a player, name, title (director, coach, staff, etc.), and picture of the log-in user may be managed in a table (not shown) similar with the player information table  23 , and those information may be displayed in the log-in user display area  41 . 
         [0061]    The display control unit  12  displays, based on pitching meta data of the pitch scene for last several games of the log-in user delivered from the acquisition unit  11 , the at-bat result for a predetermined number of at-bats in the descending order from a latest at-bat, in the recent at-bat display area  42 . For example, in the example of  FIG. 9 , the display control unit  12  displays, for each at-bat, the date, inning, opponent team, opponent pitcher or opponent batter, and at-bat result in each of frames. When a frame indicating any at-bat is selected from the recent at-bat display area  42 , the display control unit  12  delivers the pitching meta data used for displaying information of the selected at-bat to the acquisition unit  11  as the retrieval condition. 
         [0062]    The display control unit  12  generates the performance card based on the thumbnail image and pitching meta data delivered from the acquisition unit  11 . The performance card provides information recommended to the log-in user such as performance of the game in which the log-in user played and performance of the game in which a user followed by the log-in user played, in a card format. The performance card indicates a thumbnail image of the pitch scene and predetermined information extracted from the pitching meta data. The predetermined information is different depending on whether the target player (log-in user or user followed by log-in user) of the performance card is a pitcher or a fielder. More specifically, in the case where the target player of the performance card is a fielder, the predetermined information may be, for example, the at-bat result of each at-bat. In the case where the target player of the performance card is a pitcher, the predetermined information may be, for example, the opponent team. Since most of fielders play in almost every game, the performance card of the game may be easily recognized by indicating the at-bat result for each of games. Since the pitcher, especially a starting pitcher, does not play in every game, the performance card of the game may be more easily recognized by indicating the opponent team rather than by indicating such as the pitch result of each pitch in the game, for example. 
         [0063]    In the case where the message is assigned with the pitch scene, the display control unit  12  generates a performance card including a thumbnail image of the pitch scene and the message. The display control unit  12  also generates a performance card for other information included in the top page information. For example, in the case where a meeting document is included in the top page information, the display control unit  12  may generate a performance card which describes the date when the meeting is held, with the meeting document attached thereto. 
         [0064]    The display control unit  12  displays the generated performance card in the time line display area  43  by arranging, in the descending order, dates relevant to the performance card such as, for example, date of the game indicated by the performance card, date included in the message, and date when the meeting is held. For example, in the example of  FIG. 9 , performance cards  44 A and  44 E are performance cards indicating performance of games in which the log-in user played. The performance card  44 A is a performance card of a last game, and the performance card  44 E is a performance card of a game preceding the last game. In the example of  FIG. 9 , the log-in user is a fielder. Thus, performance cards  44 A and  44 E indicate the at-bat result of each at-bat. 
         [0065]    A performance card  44 B is a performance card indicating performance of a game in which a player (pitcher) followed by the log-in user plays, and a performance card  44 C is a performance card indicating performance of a game in which a player (fielder) followed by the log-in user plays. The performance card  44 B indicates the opponent team as the target player is a pitcher, and the performance card  44 C indicates the at-bat result of each at-bat as the target player is a fielder. 
         [0066]    A performance card  44 D is an example of a performance card to which a meeting document or the like is attached, and a performance card  44 F is an example of a performance card to which a message is assigned. Hereinafter, when collectively referred to without distinction, the performance cards  44 A,  44 B,  44 C,  44 D,  44 E, and  44 F are merely represented by “performance card  44 ”. 
         [0067]    When any performance card  44  including a thumbnail image is selected from the time line display area  43 , the display control unit  12  delivers the pitching meta data used for generating the selected performance card  44  to the acquisition unit  11  as the retrieval condition. When a performance card  44  not including a thumbnail image is selected, the display control unit  12  performs a processing corresponding to the performance card  44  such as opening of a document attached to the performance card  44 . 
         [0068]    When the retrieval and reproduction tab  32  is selected, the display control unit  12  displays, for example, a retrieval and reproduction screen  50  such as illustrated in  FIG. 10  on the display device  84 . The retrieval and reproduction screen  50  includes a top page tab  31 , a retrieval and reproduction tab  32 , a personal result tab  33 , and a game log tab  34 . The retrieval and reproduction screen  50  is a screen in a state where the retrieval and reproduction tab  32  is selected. The retrieval and reproduction screen  50  includes a target player entry area  51 , an opponent player entry area  52 , a pitch/at-bat result entry area  53 , a game date entry area  54 , narrowing condition areas  55 A,  55 B,  55 C,  55 D, and a retrieval result list area  56 . The retrieval and reproduction screen  50  further includes a video image reproduction area  57  and a display control button group  58 . Each of the target player entry area  51 , opponent player entry area  52 , pitch/at-bat result entry area  53 , game date entry area  54 , and narrowing condition areas  55 A,  55 B,  55 C,  55 D is an area for entering a retrieval condition of the video image. 
         [0069]    When a select button  51 A included in the target player entry area  51  is selected, the display control unit  12  provides a display for entering the target player. For example, the display control unit  12  acquires player information in the player information table  23  of the distribution server  20 , generates a list of players for each of teams, and displays players in a selectable state. The display control unit  12  displays information of the selected player in the target player entry area  51 . 
         [0070]    When a select button  52 A included in the opponent player entry area  52  is selected, the display control unit  12  provides a display for entering the opponent player as in the case of entering the target player. The display control unit  12  displays information of the selected player in the opponent player entry area  52 . The entering method for the opponent player also includes entering all players and entering all players belonging to a specific team. When the opponent player is a pitcher, the entering method also includes entering the left-handed or right-handed player, and when the target player is a fielder, the entering method also includes entering the right-handed or left-handed player as the opponent player. 
         [0071]    When a select button  53 A included in the pitch/at-bat result entry area  53  is selected, the display control unit  12  provides a display for entering the pitch result and at-bat result. For example, the pitch result is displayed in such a manner that all pitch results, strikes, or balls are selectable. The strike may be more specific information from which called strike, swing and miss, or foul is selectable. The at-bat result may be displayed in such a manner that all at-bat results, hits, outs, or others are selectable. The hit may be displayed in such a manner that the single, double, triple, or home run is selectable. The out may be displayed in such a manner that the single out, double play, or strikeout is selectable. Others may be displayed in such a manner that the four balls, hit by pitch, sacrifice fly, or the like is selectable. Further, the hit and out may be displayed in such a manner that the more specific at-bat result such as hit to a center and fly to a right field is selectable. The display control unit  12  displays the selected pitch result or at-bat result in the pitch/at-bat result entry area  53 . 
         [0072]    Display for selecting the above target player, opponent player, and pitch/at-bat result is provided, for example, by displaying a pull-down menu or another window. An entry by direct input into the text box or the like also may be accepted. 
         [0073]    When the target player, opponent player, and pitch/at-bat result are entered, the display control unit  12  delivers the target player, opponent player, and pitch/at-bat result entered in their respective entry areas to the acquisition unit  11  as retrieval conditions. Thus, the display control unit  12  acquires the video image file  21  and pitching meta data distributed from the distribution server  20  via the acquisition unit  11 . When any performance card  44  or a recent at-bat is selected on the above top page screen  40 , the display control unit  12  displays a retrieval condition in each entry area based on the pitching meta data corresponding to the selected performance card  44  or recent at-bat. 
         [0074]    Based on the acquired pitching meta data, the display control unit  12  displays a list of retrieval results in the retrieval result list area  56  in a state where each of the retrieval results is selectable. In the example of  FIG. 10 , the display control unit  12  displays each retrieval result  56 A within one frame, wherein at-bats including the pitch scene matching the retrieval condition are displayed as one retrieval result  56 A. In the example of  FIG. 10 , a frame indicating one retrieval result contains information indicating the game date, inning, opponent team, opponent player, pitch result or at-bat result, pitch type, pitching course, hitting direction, and the ordinary number of pitch in the at-bat. Unless the retrieval condition selecting the pitched ball is not entered, the retrieval result  56 A is displayed based on pitching meta data for a pitch scene indicating a last pitched ball in the at-bat. In the case where the retrieval condition selecting the pitched ball is entered, the retrieval result  56 A is displayed based on pitching meta data for a pitch scene matching the retrieval condition. The retrieval condition selecting the pitched ball is entered with the pitch result entered in the pitch/at-bat result entry area  53  and with any of narrowing conditions described below. The pitching course and hitting direction are represented by a symbol image indicating the pitching course and a symbol image indicating the hitting direction respectively. 
         [0075]    The display control unit  12  displays a selected retrieval result  56 A out of retrieval results  56 A included in the retrieval result list area  56 , in a display mode different from other retrieval results  56 A. In the example of  FIG. 10 , the frame line of the selected retrieval result  56 A is depicted with a heavy line, and unselected frame lines of retrieval results  56 A are depicted with a broken line. 
         [0076]    When a situation display button  56 B included in the retrieval result list area  56  is selected, the display control unit  12 , for example, develops display of the retrieval result list area  56  and additionally displays the situation of the count and runner within the frame of each retrieval result  56 A as illustrated in  FIG. 11 . In the example of  FIG. 11 , the situation of the count and runner is represented by a symbol image indicating the count, and a symbol image indicating the situation of the runner respectively. 
         [0077]    When an all-pitches display button  56 C included in each retrieval result  56 A is selected, the display control unit  12 , for example, develops display of a retrieval result  56 A matching the selected all-pitches display button  56 C as illustrated in  FIG. 12 . Then, the display control unit  12  displays information of each pitch scene included in the at-bat indicated by the retrieval result  56 A. The display control unit  12  displays information of the pitch scene displayed before developing the retrieval result  56 A, in a display mode different from other pitch scenes. In the example of  FIG. 12 , the display control unit  12  makes reverse display in a portion indicating for which pitch in the at-bat the pitch scene is displayed before developing the retrieval result  56 A. 
         [0078]    Based on the pitching meta data corresponding to the retrieval result  56 A selected in the retrieval result list area  56 , the display control unit  12  identifies the selected pitch scene out of the acquired video image file  21  and reproduces in the video image reproduction area  57 . More specifically, the display control unit  12  identifies the video image file  21  by “file name” of the pitching meta data corresponding to the selected retrieval result  56 A, and reproduces the identified video image file  21  from a frame indicated by the frame time in “pitch tag” of the pitching meta data. When any retrieval result  56 A is not selected from the retrieval result list area  56  by the log-in user, reproduction may be started automatically from a video image corresponding to a predetermined retrieval result  56 A, for example, such as a leading retrieval result  56 A. 
         [0079]    When any button included in the display control button group  58  is selected, the display control unit  12  performs display control matching the selected button for the video image reproduced in the video image reproduction area  57 . The display control button group  58 , for example, includes a reproduction/pause button, a fast reversing button, a fast-forward button, a frame feed button, a frame reversing button, and so on. When the reproduction/pause button is selected, the display control unit  12  performs pause control of the video image being reproduced or performs reproduction control of the video image being paused. When the fast reversing button is selected, the display control unit  12  performs fast reversing control of the video image being reproduced, and when the fast-forward button is selected, the display control unit  12  performs fast-forward control of the video image being reproduced. When the frame reversing button is selected, the display control unit  12  performs frame reversing control of the video image being reproduced, and when the frame feed button is selected, the display control unit  12  performs frame feed control of the video image being reproduced. 
         [0080]    When the game date is entered and any narrowing condition is entered, the display control unit  12  narrows retrieval results  56 A displayed in the retrieval result list area  56  and updates display of the retrieval result list area  56 . 
         [0081]    More specifically, when the game date is entered in the game date entry area  54 , the display control unit  12  narrows retrieval results  56 A displayed in the retrieval result list area  56  into a retrieval result  56 A matching the entered game date. 
         [0082]    The narrowing condition is entered in each of narrowing condition areas  55 A,  55 B,  55 C, and  55 D. The narrowing condition area  55 A is selected when the pitching course is entered as the narrowing condition. The narrowing condition area  55 B is selected when the pitch type is selected as the narrowing condition. The narrowing condition area  55 C is selected when the hitting direction is selected as the narrowing condition. The narrowing condition area  55 D is selected when the situation of the count and runner is entered as the narrowing condition. 
         [0083]    When the narrowing condition area  55 A is selected, the display control unit  12  develops and displays, for example, a narrowing condition entry area  551 A for entering the pitching course on the video image reproduction area  57  as illustrated in  FIG. 13 . The narrowing condition entry area  551 A includes a specifying component  552 A of a symbol image indicating the pitching course for receiving the pitching course to be entered as the narrowing condition. The display control unit  12  displays the block of the selected pitching course in a display mode different from blocks of pitching courses not selected. In the example of  FIG. 13 , the selected block is indicated by halftone dots. 
         [0084]    The narrowing condition entry area  551 A includes a total pitch count display  553 A included in the retrieval result  56 A displayed in the current retrieval result list area  56 . Each block of the specifying component  552 A indicates the number of pitches whose pitching course matches the pitching course indicated by the block out of all pitches included in all retrieval results  56 A indicated in the current retrieval result list area  56 . The narrowing condition entry area  551 A includes a clear button  554 A for clearing the select state of the specifying component  552 A and an OK button  555 A for determining the select state of the specifying component  552 A. 
         [0085]    When the OK button  555 A is selected, the display control unit  12  narrows retrieval results  56 A indicated in the retrieval result list area  56  into a retrieval result  56 A whose pitching course matches the pitching course entered in the specifying component  552 A, and updates display of the retrieval result list area  56 . Then, when any retrieval result  56 A is selected from the retrieval result list area  56 , the display control unit  12  clears display of the narrowing condition entry area  551 A, displays the video image reproduction area  57 , and reproduces a video image indicated by the selected retrieval result  56 A. The display control unit  12  updates the display of the symbol image representing the pitching course in the narrowing condition area  55 A to a display reflecting the condition entered in the specifying component  552 A. 
         [0086]    When the narrowing condition area  55 B is selected, the display control unit  12  develops and displays, for example, a narrowing condition entry area  551 B for entering the pitch type on the video image reproduction area  57  as illustrated in  FIG. 14 . The narrowing condition entry area  551 B includes a specifying component  552 B for receiving the pitch type to be entered as the narrowing condition. Similarly with the narrowing condition entry area  551 A, the narrowing condition entry area  551 B includes the total pitch count display  553 B and indicates the number of pitches of each pitch type of the specifying component  552 B. Further, the narrowing condition entry area  551 B also includes a display  556 B in which the number of pitches of each pitch type is graphed. The narrowing condition entry area  551 B further includes a clear button  554 B and an OK button  555 B. 
         [0087]    Display control upon selection of the specifying component  552 B, the clear button  554 B, and the OK button  555 B is the same as in the narrowing condition entry area  551 A. Also, updating of the retrieval result list area  56  and display control after selection of the retrieval result  56 A from the updated retrieval result list area  56  are the same as in the narrowing condition area  55 A. 
         [0088]    When the narrowing condition area  55 C is selected, the display control unit  12  develops and displays, for example, a narrowing condition entry area  551 C for entering the hitting direction on the video image reproduction area  57  as illustrated in  FIG. 15 . The narrowing condition entry area  551 C includes a specifying component  552 C of a symbol image representing the hitting direction for receiving the hitting direction to be entered as the narrowing condition.  FIG. 15  illustrates an example of the specifying component  552 C in which how the hit ball rises (groundball or fly) may be entered as a specifying condition along with the hitting direction. Similarly with the narrowing condition entry area  551 A, the narrowing condition entry area  551 C includes a total pitch count display  553 C and also indicates the number of pitches in each hitting direction of the specifying component  552 C. The narrowing condition entry area  551 C includes a clear button  554 C and an OK button  555 C. 
         [0089]    Display control upon selection of the specifying component  552 C, clear button  554 C, and OK button  555 C is the same as in the narrowing condition entry area  551 A. Also, updating of the retrieval result list area  56  and display control after selection of the retrieval result  56 A from the updated retrieval result list area  56  are the same as in the narrowing condition area  55 A. A narrowing condition area  55 C of  FIG. 16  described below indicates an example where the hitting direction is not entered as the narrowing condition in  FIG. 15 . 
         [0090]    When the narrowing condition area  55 D is selected, the display control unit  12  develops and displays, for example, a narrowing condition entry area  551 D for entering the situation of the count and runner on the video image reproduction area  57  as illustrated in  FIG. 16 . The narrowing condition entry area  551 D includes a specifying component  552 D of a symbol image representing the situation of the count and runner for receiving the situation of the count and runner to be entered as the narrowing condition. 
         [0091]      FIG. 16  illustrates an example of the specifying component  552 D including a button for entering a situation which is difficult to enter with the symbol image only. For example, a button of “no runner” is used to enter a situation where there is no runner, for distinguishing from the case where the runner&#39;s situation is not entered. The same also applies to a “first pitch” button. “Scoring position” makes it possible to enter multiple situations which are difficult to enter with the symbol image, such as a situation where a runner(s) is on the second base, on second and third bases, or on the third base. The same also applies to “two strikes” and “full count” buttons. 
         [0092]    Similarly with the narrowing condition entry area  551 A, the narrowing condition entry area  551 D includes the total pitch count display  553 D. The narrowing condition entry area  551 D includes a clear button  554 D and an OK button  555 D. 
         [0093]    Display control upon selection of the specifying component  552 D, clear button  554 D, and OK button  555 D is the same as in the narrowing condition entry area  551 A. Also, updating of the retrieval result list area  56  and display control after selection of the retrieval result  56 A from the updated retrieval result list area  56  are the same as in the narrowing condition area  55 A. 
         [0094]    Hereinafter, when collectively referred to without distinction, narrowing condition areas  55 A,  55 B,  55 C, and  55 D are merely represented by “narrowing condition area  55 ”. In the same manner, when collectively referred to without distinction, the narrowing condition entry area, specifying component, clear button, and OK button are represented respectively by a reference numeral excluding the sign A, B, C, or D. 
         [0095]    When the personal result tab  33  is selected, the display control unit  12  displays, for example, a personal result screen  60  such as illustrated in  FIGS. 17 and 18  on the display device  84 . The personal result screen  60  includes a top page tab  31 , a retrieval and reproduction tab  32 , a personal result tab  33 , and a game log tab  34 . The personal result screen  60  is a screen in a state where the personal result tab  33  is selected. The personal result screen  60  includes a target player entry area  61  and result display areas  62 A to  62 H. The target player entry area  61  is the same as the target player entry area  51  of the retrieval and reproduction screen  50 . Hereinafter, when collectively referred to without distinction, result display areas  62 A to  62 H are merely represented by “result display area  62 ”. 
         [0096]    When the target player is entered in the target player entry area  61 , the display control unit  12  transmits the player ID of the entered player to the distribution server  20  and acquires result information of the player from the result information table  26  of the distribution server  20 . Based on the acquired result information, the display control unit  12  displays the result in the format of a graph or a symbol image in the result display area  62 . 
         [0097]      FIG. 17  illustrates an example of the personal result screen  60  when the target player is a fielder. The result display area  62 A displays a result on “at-bat result breakdown” in a graph format and displays a specifying component  63 A in which each at-bat result as a result item may be selected. The result display area  62 B displays a result on “hitting direction breakdown” in association with each block of the symbol image indicating the hitting direction. The symbol image indicating the hitting direction also functions as the specifying component  63 B in which a block indicating each hitting direction as the result item may be selected. The result display area  62 C displays a result on “course-based batting average” in association with each block of the symbol image indicating the pitching course. The symbol image indicating the hitting direction also functions as a specifying component  63 C in which a block indicating each pitch as the result item may be selected. The result display area  62 D displays a result on “pitch type-based batting average” in a graph format and displays a specifying component  63 D in which each pitch type as the result item may be selected. 
         [0098]      FIG. 18  illustrates an example of the personal result screen  60  when the target player is a pitcher. A result display area  62 E displays a result on “at-bat-based pitch result breakdown” in a graph format and displays a specifying component  63 E in which each at-bat result as the result item may be selected. A result display area  62 F displays a result on “situation based batted average” as a selectable button in association with a symbol image representing each situation. Each button also functions as the specifying component  63 B in which each situation as the result item may be selected. A result display area  62 G displays a result on “course-based batted average” in association with each block of the symbol image indicating the pitching course. The symbol image indicating the pitching course also functions as a specifying component  63 G in which a block indicating each pitching course as the result item may be selected. A result display area  62 H displays a result on “pitch type-based batted average” in a graph format and displays a specifying component  63 H in which each pitch type as the result item may be selected. 
         [0099]    The display control unit  12  may display the graph and symbol image of each result item indicated on each result display area  62  in a different color depending on, for example, whether the result in the result item is not lower than or not higher than a predetermined value. Hereinafter, when collectively referred to without distinction, specifying components  63 A to  63 H are merely represented by “specifying component  63 ”. 
         [0100]    When any result item is selected by operating any specifying component  63 , the display control unit  12  delivers the at-bat result, hitting direction, pitching course, pitch type, or situation of the count and runner corresponding to the selected result item to the acquisition unit  11  as the retrieval condition. Thus, the display control unit  12  acquires the video image file  21  and pitching meta data distributed from the distribution server  20  via the acquisition unit  11 . The display control unit  12  switches the screen to the retrieval and reproduction screen  50 , displays the retrieval condition specified by the specifying component  63  in an entry area of the retrieval condition, and displays the retrieval result list in the retrieval result list area  56  based on the acquired pitching meta data. For example, assume that a 17th block (a second block from the left on the fourth row) is selected from the specifying component  63 C included in the result display area  62 C of the course-based batting average in the personal result screen  60  illustrated in  FIG. 17 . In this case, the display control unit  12  displays, in the target player entry area  51  of the retrieval and reproduction screen  50 , information of the player entered in the target player entry area  61  of the personal result screen  60 , and changes display of the narrowing condition area  55 A into a state where the 17th block is entered. Also, all players are entered in the opponent player entry area  52 , all are entered in the pitch/at-bat result entry area  53 , nothing is entered in the game date entry area  54 , and nothing is entered in the narrowing condition areas  55 B,  55 C, and  55 D. 
         [0101]    When the game log tab  34  is selected, the display control unit  12  displays, for example, a game log screen  70  such as illustrated in  FIG. 19  on the display device  84 . The game log screen  70  includes a top page tab  31 , a retrieval and reproduction tab  32 , a personal result tab  33 , and a game log tab  34 . The game log screen  70  is a screen in a state where the game log tab  34  is selected. The game log screen  70  includes a game date entry area  71 , a select button  72 , a game overview display area  73 , and a box score display area  74 . The game date entry area  71  may be a text box in which the date may be entered directly into a text box, or may be a pull-down menu in which the date may be selected or in a format in which a calendar is displayed in a separate window. In the case where the calendar is displayed, the opponent team may be indicated in each date field. 
         [0102]    When the game date is entered in the game date entry area  71 , the display control unit  12  transmits the entered game date to the distribution server  20  via the acquisition unit  11 . The distribution server  20  identifies the game based on the entered game date and the team to which the log-in user belongs, extracts game information of the game from the game information table  27 , and extracts pitching meta data of the game from the pitching meta data table  25 . Then, the distribution server  20  transmits the extracted game information and pitching meta data as well as the video image file  21  of the game to the display controller  10 . The display control unit  12  acquires the game information, pitching meta data, and video image file  21  via the acquisition unit. 
         [0103]    The display control unit  12  displays the content of the acquired game information in the game overview display area  73  in a predetermine format. In the example of  FIG. 19 , the inning-based score is indicated in a score board format. Based on the acquired pitching meta data, the display control unit  12  generates a box score in which the inning based result of each player arranged in the batting order is represented in a matrix format, and displays in the box score display area  74  in a state where each frame (each at-bat) is selectable. 
         [0104]    When any frame (at-bat) is selected from the box score, the display control unit  12  switches the screen to the retrieval and reproduction screen  50 . Based on the pitching meta data of the selected at-bat, the display control unit  12  displays the retrieval condition in each entry area, and displays information of the selected at-bat in the retrieval result list area  56  as the retrieval result  56 A and reproduces the video image of the at-bat in the video image reproduction area  57 . 
         [0105]    The display controller  10  may be implemented, for example, by a computer  80  illustrated in  FIG. 20 . The computer  80  comprises a CPU  81 , a memory  82  as a temporary storage area, and a nonvolatile storage unit  83 . Also, the computer  80  comprises a display devise  84 , a read/write (R/W) unit  85  configured to control reading and writing of data into a recording medium  89 , and a network interface (I/F)  86  connected to the network such as the internet. The CPU  81 , memory  82 , storage unit  83 , display device  84 , R/W unit  85 , and the network I/F  86  are coupled to each other via a bus  87 . 
         [0106]    The storage unit  83  may be implemented by a hard disk drive (HDD), a solid state drive (SSD), a flash memory, or the like. The storage unit  83  as a recording medium stores a display control program  90  configured to cause the computer  80  to function as the display controller  10 . The display control program  90  includes an acquisition process  91  and a display control process  92 . 
         [0107]    The CPU  81  is configured to read out the display control program  90  from the storage unit  83 , develop in the memory  82 , and run processes of the display control program  90  sequentially. The CPU  81  operates as the acquisition unit  11  illustrated in  FIG. 1  by running the acquisition process  91 . The CPU  81  operates as the display control unit  12  illustrated in  FIG. 1  by running the display control process  92 . Thus, the computer  80 , which has run the display control program  90 , functions as the display controller  10 . 
         [0108]    Functions implemented by the display control program  90  also may be implemented, for example, by a semiconductor integrated circuit, more particularly, by an application specific integrated circuit (ASIC) or the like. 
         [0109]    Next, operation of the display controller  10  according to the embodiment is described. When the application provided by the display controller  10  is activated by the user&#39;s log-in with entry of the user ID, a display control processing illustrated in  FIG. 21  is performed in the display controller  10 . 
         [0110]    In the step S 11 , the acquisition unit  11  receives the user ID of the entered log-in user, transmits the user ID to the distribution server  20 , and requests top page information including player information, thumbnail image, and pitching meta data relative to the log-in user. 
         [0111]    Next, in the step S 12 , the acquisition unit  11  acquires the top page information transmitted from the distribution server  20  in response to the request. The acquisition unit  11  delivers the acquired top page information to the display control unit  12 . 
         [0112]    Next, in the step S 13 , the display control unit  12  generates the performance card  44  based on the thumbnail image and pitching meta data delivered from the acquisition unit  11 . In this step, in the case where the log-in user is a fielder, the display control unit  12  generates a performance card  44  including the at-bat result of each at-bat in the concerned game. In the case where the log-in user is a pitcher, the display control unit  12  generates a performance card  44  including the opponent team in the concerned game. The display control unit  12  also generates other performance cards  44  based on the top page information such as a performance card  44  accompanied by a message and a performance card accompanied by an attached file. 
         [0113]    Next, in the step S 14 , the display control unit  12  displays, for example, a top page screen  40  such as illustrated in  FIG. 9 . More specifically, the display control unit  12  displays, based on the player information of the log-in user delivered from the acquisition unit  11 , player&#39;s name, team, position, uniform number, throwing method or hitting method, and picture of the log-in user, in the log-in user display area  41 . The display control unit  12  also displays, based on pitching meta data of the pitch scene for last several games of the log-in user delivered from the acquisition unit  11 , the at-bat result for a predetermined number of at-bats in the descending order from a latest at-bat, in the recent at-bat display area  42 . Further, the display control unit  12  displays performance cards  44  generated in the above step S 13  in the time line display area  43  in the descending order of the date of respective performance cards  44 . 
         [0114]    Next, in the step S 15 , the display control unit  12  determines whether any performance card  44  including the thumbnail image is selected or any at-bat is selected from the recent at-bat display area  42  on the top page screen  40 . When any performance card  44  or a recent at-bat is selected, processing proceeds to the step S 16 , and when neither the performance card  44  nor the recent at-bat is selected, processing proceeds to the step S 19 . In this step, when a performance card  44  not including the thumbnail image is selected, the display control unit  12  performs display control matching the selected performance card  44 . 
         [0115]    In the step S 16 , the display control unit  12  delivers the pitching meta data used for generating the selected performance card  44  or pitching meta data used for displaying the selected recent at-bat information to the acquisition unit  11  as the retrieval condition. Thus, the display control unit  12  acquires the video image file  21  and pitching meta data matching the retrieval condition from the distribution server  20  via the acquisition unit  11 . 
         [0116]    Next, in the step S 17 , the display control unit  12  displays a retrieval condition in each entry area based on pitching meta data corresponding to the selected performance card  44  or recent at-bat. Based on the acquired pitching meta data, the display control unit  12  displays a list of retrieval results  56 A indicating an at-bat corresponding to the selected performance card  44  or a list of retrieval results  56 A indicating an at-bat selected from the recent at-bat display area  42  in the retrieval result list area  56 . Then, processing proceeds to the step S 24  of the retrieval and reproduction screen processing described below, and the display control unit  12  starts reproduction of a video image indicating the pitch scene included in an at-bat corresponding to the selected performance card  44  or the selected recent at-bat in the video image reproduction area  57 . 
         [0117]    Meanwhile, in the step S 19 , the display control unit  12  determines whether the retrieval and reproduction tab  32  is selected on the top page screen  40 . When the retrieval and reproduction tab  32  is selected, processing proceeds to the step S 20 , retrieval and reproduction screen processing described below is performed, and the display control processing ends. When the retrieval and reproduction tab  32  is not selected, processing proceeds to the step S 35 . 
         [0118]    In the step S 35 , the display control unit  12  determines whether the personal result tab  33  is selected on the top page screen  40 . When the personal result tab  33  is selected, processing proceeds to the step S 40 , personal result screen processing described below is performed, and the display control processing ends. When the personal result tab  33  is not selected, processing proceeds to the step S 55 . 
         [0119]    In the step S 55 , the display control unit  12  determines whether the game log tab  34  is selected on the top page screen  40 . When the game log tab  34  is selected, processing proceeds to the step S 60 , game log screen processing described below is performed, and the display control processing ends. When the game log tab  34  is not selected, processing proceeds to the step S 65 . 
         [0120]    In the step S 65 , the display control unit  12  determines whether a command instructing to end the application has been entered, and then determines whether to end the application. When not ending the application, processing returns to the step S 15 , and when ending the application, the display control processing ends. 
         [0121]    Here, the retrieval and reproduction screen processing is described with reference to  FIG. 22 . 
         [0122]    In the step S 21 , the display control unit  12  determines whether the retrieval condition is entered in the target player entry area  51 , opponent player entry area  52 , and pitch/at-bat result entry area  53 . When the retrieval conditions are entered in these entry areas, processing proceeds to the step S 22 , and when the retrieval conditions are not entered, processing proceeds to the step S 25 . 
         [0123]    In the step S 22 , the display control unit  12  delivers the target player, opponent player, and pitch/at-bat result entered in the respective entry areas to the acquisition unit  11  as the retrieval conditions. Thus, the display control unit  12  acquires the video image file  21  and pitching meta data matching the retrieval conditions, which are distributed from the distribution server  20  via the acquisition unit  11 . 
         [0124]    Next, in the step S 23 , the display control unit  12  displays, based on the acquired pitching meta data, a list of retrieval results in the retrieval result list area  56  in a state where each of the retrieval results  56 A is selectable. 
         [0125]    Next, in the step S 24 , the display control unit  12  identifies, based on the pitching meta data corresponding to the retrieval result  56 A selected in the retrieval result list area  56 , the selected pitch scene out of the acquired video image file  21  and starts reproduction in the video image reproduction area  57 . In this step, in the case where a retrieval result  56 A is selected in a state where the all-pitches display button  56 C is not selected, the display control unit  12  sequentially reproduces video images representing pitch scenes included in the at-bat indicated by the retrieval result  56 A. In the case where the all-pitches display button  56 C is selected and a specific pitch scene is selected from the developed and displayed retrieval results  56 A, the display control unit  12  reproduces the video image displaying the selected pitch scene. 
         [0126]    In the step S 25 , the display control unit  12  determines whether any narrowing condition area  55  is selected in the retrieval and reproduction screen  50 . When any narrowing condition area  55  is selected, processing proceeds to the step S 26 , and when no narrowing condition area  55  is selected, processing proceeds to the step S 31 . In this step, when the game date is entered in the game date entry area  54 , the display control unit  12  narrows retrieval results  56 A indicated in the retrieval result list area  56  into a retrieval result  56 A matching the entered game date. 
         [0127]    In the step S 26 , the display control unit  12 , for example, develops and displays a narrowing condition entry area  551  corresponding to the selected narrowing condition area  55  on the video image reproduction area  57  as illustrated in  FIGS. 13 to 16 . 
         [0128]    Next, in the step S 27 , the display control unit  12  determines whether the OK button  555  is selected with the narrowing condition selected by operating the specifying component  552  in the narrowing condition entry area  551  and thereby determines whether the narrowing condition is entered. When the narrowing condition is entered, processing proceeds to the step S 28 , and when the narrowing condition is not entered, processing returns to the step S 25 . 
         [0129]    In the step S 28 , the display control unit  12  narrows retrieval results  56 A displayed in the retrieval result list area  56  with the narrowing condition entered in the specifying component  552 , and updates display of the retrieval result list area  56 . 
         [0130]    Next, in the step S 29 , the display control unit  12  determines whether any retrieval result  56 A is selected from the updated retrieval result list area  56 . When any retrieval result  56 A is entered, processing proceeds to the step S 30 , and when no retrieval result  56 A is entered, processing returns to the step S 25 . Back to the step S 25 , when another tab or another narrowing condition area  55  is not selected, the select state of the currently selected narrowing condition area  55  is maintained. Specifically, in the step S 26 , display state of the narrowing condition entry area  551  developed on the video image reproduction area  57  is maintained. 
         [0131]    In the step S 30 , the display control unit  12  hides display of the narrowing condition entry area  551  developed and displayed on the video image reproduction area  57 , and displays the video image reproduction area  57 . The display control unit  12  updates display of the narrowing condition area  55  to a display reflecting the condition entered in the specifying component  552 . Then, processing returns to the step S 24 , and reproduction of the video image indicated by the selected retrieval result  56 A is started. 
         [0132]    Meanwhile, in the step S 31 , the display control unit  12  determines whether the top page tab  31  is selected on the retrieval and reproduction screen  50 . When the top page tab  31  is selected, processing returns to the step S 12  of the display control processing ( FIG. 21 ), and the display control unit  12  displays the top page screen  40 . When the top page tab  31  is not selected, processing proceeds to the step S 32 . 
         [0133]    In the step S 32 , the display control unit  12  determines whether the personal result tab  33  or the game log tab  34  is selected on the retrieval and reproduction screen  50 . When the personal result tab  33  or game log tab  34  is selected, processing returns to the step S 19  of the display control processing ( FIG. 21 ). When neither the personal result tab  33  nor the game log tab  34  is selected, processing proceeds to the step S 33 , and the display control unit  12  determines whether to end the application. When not ending the application, processing returns to the step S 21 , and when ending the application, the display control processing ends. 
         [0134]    Next, the personal result screen processing is described with reference to  FIG. 23 . 
         [0135]    In the step S 41 , the display control unit  12  transmits the player ID of the player entered in the target player entry area  61  to the distribution server  20  and acquires result information of the player from the result information table  26  of the distribution server  20 . Player information of the log-in user may be established in the target player entry area  61  as a default setting when the screen shifts to the personal result screen  60 . 
         [0136]    Next, in the step S 42 , the display control unit  12  displays, based on the acquired result information, the result represented by a graph or a symbol image in the result display area  62  in a different format depending on whether the entered player is a fielder or a pitcher. 
         [0137]    Next, in the step S 43 , the display control unit  12  determines whether any result item is selected by operating the specifying component  63  of any result display area  62 . When any result item is selected, processing proceeds to the step S 44 , and when no result item is selected, processing proceeds to the step S 46 . 
         [0138]    In the step S 44 , the display control unit  12  delivers the at-bat result, hitting direction, pitching course, pitch type, or count and runner situation corresponding to the selected result item to the acquisition unit  11  as the retrieval condition. Thus, the display control unit  12  acquires the video image file  21  and pitching meta data distributed from the distribution server  20  via the acquisition unit  11 . 
         [0139]    Next, in the step S 45 , the display control unit  12  displays a retrieval condition corresponding to the selected result item in each entry area of the retrieval and reproduction screen  50 . The display control unit  12  displays, based on the acquired pitching meta data, a list of retrieval results  56 A indicating the at-bat corresponding to the selected result item in the retrieval result list area  56 . Then, processing proceeds to the step S 24  of the retrieval and reproduction screen processing ( FIG. 22 ), and the display control unit  12  starts reproduction of a video image representing the pitch scene included in an at-bat corresponding to the selected result item in the video image reproduction area  57 . 
         [0140]    Meanwhile, in the step S 46 , the display control unit  12  determines whether the top page tab  31  is selected on the personal result screen  60 . When the top page tab  31  is selected, processing returns to the step S 12  of the display control processing ( FIG. 21 ), and the display control unit  12  displays the top page screen  40 . When the top page tab  31  is not selected, processing proceeds to the step S 47 . 
         [0141]    In the step S 47 , the display control unit  12  determines whether the retrieval and reproduction tab  32  or the game log tab  34  is selected on the personal result screen  60 . When the retrieval and reproduction tab  32  or the game log tab  34  is selected, processing returns to the step S 19  of the display control processing ( FIG. 21 ). When neither the retrieval and reproduction tab  32  nor the game log tab  34  is selected, processing proceeds to the step S 48 , and the display control unit  12  determines whether to end the application. When not ending the application, processing returns to the step S 41 , and when ending the application, the display control processing ends. 
         [0142]    Next, the game log screen processing is described with reference to  FIG. 24 . 
         [0143]    In the step S 61 , the display control unit  12  switches the screen to the game log screen  70  and transmits the game date entered in the game date entry area  71  to the distribution server  20 . Then, the display control unit  12  acquires the game information and pitching meta data of the game identified based on the entered game date and the team to which the log-in user belongs. Also, the game of a team other than the team to which the log-in user belongs may be entered. 
         [0144]    Next, in the step S 62 , the display control unit  12  displays the content of the acquired game information in the game overview display area  73  in a predetermine format. The display control unit  12  displays, based on the acquired pitching meta data, a box score from which each frame (each at-bat) is selectable, in the box score display area  74 . 
         [0145]    Next, in the step S 63 , the display control unit  12  determines whether any frame (at-bat) is selected from the box score. When any at-bat is selected, processing proceeds to the step S 64 , and when no at-bat is selected, processing proceeds to the step S 66 . 
         [0146]    In the step S 64 , the display control unit  12  delivers the pitching meta data of the selected at-bat to the acquisition unit  11  as the retrieval condition. Thus, the display control unit  12  acquires the video image file  21  distributed from the distribution server  20  via the acquisition unit  11 . 
         [0147]    Next, in the step S 65 , the display control unit  12  extracts pitching meta data of the at-bat selected in the above step S 63  from the pitching meta data acquired in the above step S 61 , and displays the retrieval condition based on the extracted pitching meta data in each entry area of the retrieval and reproduction screen  50 . The display control unit  12  displays, based on the extracted pitching meta data, a retrieval result  56 A indicating an at-bat matching the selected at-bat in the retrieval result list area  56 . Then, processing proceeds to the step S 24  of the retrieval and reproduction screen processing ( FIG. 22 ), and the display control unit  12  starts, in the video image reproduction area  57 , reproduction of a video image displaying the pitch scene included in an at-bat selected from the box score. 
         [0148]    Meanwhile, in the step S 66 , the display control unit  12  determines whether the top page tab  31  is selected on the game log screen  70 . When the top page tab  31  is selected, processing returns to the step S 12  of the display control processing ( FIG. 21 ), and the display control unit  12  displays the top page screen  40 . When the top page tab  31  is not selected, processing proceeds to the step S 67 . 
         [0149]    In the step S 67 , the display control unit  12  determines whether the retrieval and reproduction tab  32  or the personal result tab  33  is selected on the game log screen  70 . When the retrieval and reproduction tab  32  or the personal result tab  33  is selected, processing returns to the step S 19  of the display control processing ( FIG. 21 ). When neither the retrieval and reproduction tab  32  nor the personal result tab  33  is selected, processing proceeds to the step S 68 , and the display control unit  12  determines whether to end the application. When not ending the application, processing returns to the step S 61 , and when ending the application, the display control processing ends. 
         [0150]    When any button of the reproduction control button group  58  is selected while the video image is being reproduced in the above step S 24 , the display control unit  12  performs reproduction control matching the selected button. When a message assigning button (not shown) is selected during reproduction of the video image, upon receiving a message from the user, the display control unit  12  assigns the received message to a pitch scene indicated by the video image being reproduced. The message assigned to the pitch scene is not limited to a character message using a text data, but may be a tag indicating approval or sympathy such as a “great !” button widely used in applications of the social networking service (SNS). 
         [0151]    As illustrated above, when a player logs in, for example, the display controller according to the embodiment displays the thumbnail image of a video image to be presented to the player, and together displays information associated with the thumbnail image. The information associated with the thumbnail image is switched over depending on whether the player is a fielder or a pitcher. More specifically, when the player is a pitcher, information indicating the opponent team is displayed, and when the player is a fielder, each at-bat result in one game is displayed. Thus, appropriate information may be displayed according to the attribute of the player. 
         [0152]    The video image to be presented to the player may be a video image of a player indicated by the user ID stored in association with the user ID indicating the player who logs in, such as, for example, a video image of a player followed by the player who logs in. Thus, a thumbnail image of the video image of the player whom a log-in player focuses on and information thereof may be appropriately presented to a player who logs in. 
         [0153]    The video image to be presented to the player may be a video image of the log-in player. Thus, the thumbnail image and information thereof for checking plays of the player himself after the game in a simple and quick manner may be appropriately presented to the player who logs in. 
         [0154]    Thumbnail images associated with the information are displayed in time series in the descending order of time information such as the date of the game indicated by a video image on the thumbnail image. Thus, up-to-date information may be checked easily. 
         [0155]    In the above embodiment, the video image file is acquired at a timing when a performance card or a recent at-bat on the top page screen, a player or result in the retrieval and reproduction screen, a result item on the personal result screen or an at-bat of the box score on the game log screen is entered. However, the timing of acquiring the video image file is not limited thereto, but may be a timing when the retrieval condition is entered from the retrieval condition list, or a timing when a specific retrieval condition is entered. The video image file may be acquired not based on the video image file, but by capturing a partial image just covering the pitch scene matching the retrieval condition or a partial image including the pitch scene and cut in the unit of at-bat or inning. 
         [0156]    In the above embodiment, the narrowing condition entry area is developed and displayed so as to superpose across the video image reproduction area. However, the narrowing condition entry area may superpose a part of the video image reproduction area. A default retrieval and reproduction screen may display any narrowing condition entry area, and when a retrieval result is selected, a video image reproduction area may be formed in a whole or a part of the narrowing condition entry area, and then, a video image indicated by the selected retrieval result may be reproduced therein. 
         [0157]    In the above embodiment, the display controller generates a performance card therein based on the acquired top page information, but the method of generating the performance card is not limited thereto. The performance card may be generated by the distribution server and transmitted to the display controller. 
         [0158]    In the above embodiment, the retrieval target is each pitch scene of the baseball game video image. However, the retrieval target may be a scene segmented in another unit such as an at-bat unit or inning unit. In this case, similarly with the pitch tag of the above embodiment, a tag may be assigned for a segment of the at-bat and inning, and information on a scene starting from a frame to which the tag is assigned may be prepared as meta data. Retrieval target is not limited to the video image, but may be a still picture. 
         [0159]    In the above embodiment, the display control program  90  is pre-stored (installed) in the storage unit  83 . However, the display control program  90  may be provided in a form recorded into a removable medium such as CD-ROM and DVD-ROM.
