　＜コメントボーナス当選者の選出＞
　上述したように、本実施形態に係るライブ配信システムでは、ライブ配信中に視聴者がリアルタイムにコメントを投稿するためのライブコメント機能を備えている。タイムラインに多数のコメントが書き込まれるほど出場者は多くの視聴者の存在を認識でき一体感を得ることができる。また視聴者もコメントを書き込むという形でその場に主体的に参加できるので、ライブコメントが多いほど、ライブ配信の場はいっそう盛り上がる。 <Selection of comment bonus winners>
As described above, the live distribution system according to the present embodiment has a live comment function for a viewer to post a comment in real time during live distribution. The more comments are written on the timeline, the more the contestants can recognize the existence of many viewers and get a sense of unity. In addition, viewers can also participate voluntarily in the form of writing comments, so the more live comments there are, the more exciting the live distribution will be.
　そこで、本実施形態に係るライブ配信システムにおいては、視聴者のコメントを促すインセンティブとして、コメントの書き込みを行った一部の視聴者に対してコメントボーナスなる報酬を付与する。具体的には、コメントの書き込みが可能となったタイミングから視聴者によるコメントの書き込み・投稿が始まるが、配信サーバ１０は、後述するタイミングで、タイムライン１２８のコメントに対して当選フラグを付与する。当選フラグが付与された視聴者が当選者でありコメントボーナスを獲得することができる。 Therefore, in the live distribution system according to the present embodiment, as an incentive to encourage viewers to comment, a reward as a comment bonus is given to some viewers who have written comments. Specifically, the viewer starts writing and posting comments from the timing when the comments can be written, but the distribution server 10 gives a winning flag to the comments on the timeline 128 at the timing described later. .. The viewer with the winning flag is the winner and can get the comment bonus.
　図３は、本実施形態に係るコメントボーナス当選時のタイムライン例１を示す図である。視聴者「Ｔａｒｏ」のコメントが書き込まれた同時のタイミングで当選フラグが発生した場合、当選フラグが発生したタイミングで書き込みした視聴者「Ｔａｒｏ」に当選フラグが付与される。このときタイムライン１２８には、例えば「Ｔａｒｏ　ＧＥＴ　ＢＯＮＵＳ＄１０，０００　Ｃｏｎｇｒａｔｕｌａｔｉｏｎ！」といったように、当該ユーザＩＤに報酬が当選した旨が全視聴者に対して認識可能に表示される。 FIG. 3 is a diagram showing an example 1 of a timeline at the time of winning a comment bonus according to this embodiment. When the winning flag is generated at the same time when the comment of the viewer "Taro" is written, the winning flag is given to the viewer "Taro" written at the timing when the winning flag is generated. At this time, the timeline 128 is recognizable to all viewers that the reward has been won for the user ID, for example, "Taro GET BONUS $ 10,000 Congratulation!".
　図４は、本実施形態に係るコメントボーナス当選時のタイムライン例２を示す図である。図４のケースにおいては、視聴者「Ｔａｒｏ」のコメントが書き込まれた直後のタイミングで当選フラグが発生した場合、当選フラグが発生したタイミングの一つ前のコメントを書き込みした視聴者「Ｔａｒｏ」に当選フラグが付与される。 FIG. 4 is a diagram showing a timeline example 2 at the time of winning the comment bonus according to the present embodiment. In the case of FIG. 4, when the winning flag is generated immediately after the comment of the viewer "Taro" is written, the viewer "Taro" who wrote the comment immediately before the timing when the winning flag is generated is set. Winning flag is given.
　図５は、本実施形態に係るコメントボーナス当選時のタイムライン例３を示す図である。図５のケースにおいては、視聴者「Ｎｉｃｋ」のコメントが書き込まれた直後のタイミングで当選フラグが発生した場合、当選フラグが発生したタイミングの次のコメントを書き込みした視聴者「Ｔａｒｏ」に当選フラグが付与される。なお、当選フラグが発生したタイミングの次のコメントを書き込みした視聴者を当選者とする場合、当選フラグの発生は視聴者からは分からないようになっている。 FIG. 5 is a diagram showing an example 3 of the timeline at the time of winning the comment bonus according to the present embodiment. In the case of FIG. 5, when the winning flag is generated immediately after the comment of the viewer "Nick" is written, the winning flag is written to the viewer "Taro" who wrote the comment next to the timing when the winning flag is generated. Is given. In addition, when the viewer who wrote the comment next to the timing when the winning flag is generated is the winner, the occurrence of the winning flag is not known to the viewer.
　（当選フラグ発生のタイミング）
　次いで、本実施形態に係る当選フラグ発生タイミングについて説明する。当選フラグ発生のタイミングは、ライブコメントの受付中であるため、タイムライン１２８にコメントの書き込みが可能となった時点からコメントの書き込みが終了となった時点迄の間となる。 (Timing of winning flag generation)
Next, the winning flag generation timing according to the present embodiment will be described. Since the live comment is being accepted, the timing of the winning flag generation is from the time when the comment can be written to the timeline 128 to the time when the comment writing is completed.
　（１）主催者（管理者）が任意のタイミングで所定操作を行うことにより、タイムライン１２８上において当選フラグを発生させる。主催者（管理者）は、例えば、競技が盛り上がっている最中、コメント書き込み数が増加してきたタイミング、もしくはコメント書き込み数が低調なタイミング等、様々な任意のタイミングで当選フラグを発生させることができる。 (1) The organizer (administrator) performs a predetermined operation at an arbitrary timing to generate a winning flag on the timeline 128. The organizer (administrator) may generate a winning flag at various arbitrary timings, such as when the number of comments written increases or when the number of comments written is low during the competition. can.
　（２）配信サーバ１０の制御の下、タイムライン１２８のコメント書き込み数に応じたタイミングで、当選フラグを発生させる。例えばタイムライン１２８にコメントの書き込みが可能となった時点から、総コメント数が例えば所定数１００００に到達したタイミングで当選フラグを発生させる。例えば「Ｔａｒｏ　ＧＥＴ　ＢＯＮＵＳ＄１０，０００　１０，０００Ｔｈ　Ｃｏｎｇｒａｔｕｌａｔｉｏｎ！」といったように、一万人目のコメント書き込み者が当選した旨が全視聴者に対して認識可能に表示される。所定数は高め且つ現実的に達成可能な値に設定することが望ましい。これにより、コメント書き込み数の増加をより促すことができる。なお、所定時間内（６０秒間）のコメント数が例えば１０００に到達したタイミングで当選フラグを発生させるようにしてもよい。 (2) Under the control of the distribution server 10, the winning flag is generated at the timing according to the number of comments written on the timeline 128. For example, from the time when comments can be written to the timeline 128, the winning flag is generated when the total number of comments reaches, for example, a predetermined number of 10,000. For example, "Taro GET BONUS $ 10,000 10,000 Th Congratulation!" Is displayed to all viewers so that the 10,000th comment writer has won. It is desirable to set the predetermined number to a high and realistically achievable value. As a result, it is possible to further promote an increase in the number of comments written. The winning flag may be generated when the number of comments within a predetermined time (60 seconds) reaches, for example, 1000.
　（３）配信サーバ１０の制御の下、競技が所定の競技状態に至ったタイミング、即ち出場者映像ウインドウ１２３における出場者の競技状態と連動したタイミングで、タイムライン１２８上において当選フラグを発生させる。 (3) Under the control of the distribution server 10, a winning flag is generated on the timeline 128 at the timing when the competition reaches a predetermined competition state, that is, at the timing linked to the competition state of the contestants in the contestant video window 123. ..
　例えば「ドリンク早飲みの競技」の場合、出場者（競技者）がドリンクを口から噴き出してしまうとリタイアとなり、競技開催画面１２０上、リタイアした出場者の出場者映像ウインドウ１２３においてシャッターが閉まり当該出場者が非表示となる。「ドリンク早飲みの競技」のようなユーモラスな競技では、出場者の競技目標の失敗シーンは、競技が盛り上がるタイミングである。そしてそのような競技が盛り上がるタイミングではコメントの書き込み量が増加する。よって配信サーバ１０は、出場者が競技に失敗したタイミング、出場者が競技にリタイアしたタイミングで、タイムライン１２８上において当選フラグを発生させる。 For example, in the case of a "drink fast-drinking competition", if a contestant (competitor) spouts a drink from his mouth, he / she will be retired, and the shutter will be closed in the contestant video window 123 of the retired contestant on the competition holding screen 120. Contestants will be hidden. In a humorous competition such as a "drink fast-drinking competition", the failure scene of the contestant's competition goal is the timing when the competition is lively. And at the timing when such competitions are exciting, the amount of comments written increases. Therefore, the distribution server 10 generates a winning flag on the timeline 128 at the timing when the contestant fails in the competition and the timing when the contestant retires from the competition.
　また競技と連動したタイミングとして、例えば「ドリンクを１本飲み干した時点（飲み干す毎）」のように、配信サーバ１０は、出場者が競技目標をクリアしたタイミングで、タイムライン１２８上において当選フラグを発生させることも可能である。出場者がドリンクを１本飲み切る度、即ち出場者が競技目標をクリアする毎にコメントボーナス当選が発生するため、視聴者の競技応援をより促すことができる。なお。配信サーバ１０は、出場者が競技に失敗したか否か、出場者が競技目標をクリアしたか否かは、出場者映像ウインドウ１２３の映像解析により判定可能である。 In addition, as a timing linked to the competition, for example, "when one drink is drunk (every time the drink is drunk)", the distribution server 10 sets a winning flag on the timeline 128 at the timing when the contestant clears the competition goal. It is also possible to generate it. Every time the contestant drinks up one drink, that is, every time the contestant clears the competition goal, a comment bonus is won, so that the viewer can be more encouraged to support the competition. note that. The distribution server 10 can determine whether or not the contestant has failed in the competition and whether or not the contestant has cleared the competition goal by video analysis of the contestant video window 123.
　また、タイムライン１２８上においてコメントの言語別に当選フラグを発生させることも可能である。視聴者が世界国々からの視聴者である場合、書込欄１２６へのコメントは、世界各国の様々な言語文字が用いられる。例えばタイムライン１２８を言語別に複数設置し、同一のタイムライン内では同一言語のコメントが表示されるようにする。その上で各々のタイムライン毎において、上記（１）～（３）に示すタイミングで当選フラグを発生させることにより、言語別（国別）に視聴者に広くコメントボーナス当選が発生させることができる。 It is also possible to generate a winning flag for each comment language on the timeline 128. When the viewer is a viewer from all over the world, the comment in the writing field 126 uses various language characters from all over the world. For example, a plurality of timelines 128 are set for each language so that comments in the same language are displayed in the same timeline. In addition, by generating the winning flag at the timings shown in (1) to (3) above in each timeline, it is possible to widely generate comment bonus winning for viewers by language (country). ..
　なお、当選フラグ発生は単数回に限られず複数回発生し得る。またその場合、複数の視聴者がコメントボーナス当選者となり得る。 The winning flag is not limited to a single number but can occur multiple times. In that case, a plurality of viewers may be winners of the comment bonus.

　Ｓ１：配信サーバ１０は、各々の視聴者端末３０からのコメント受付を開始したか否かを判定する。コメント受付を開始した場合、Ｓ２へ進む。 S1: The distribution server 10 determines whether or not the comment reception from each viewer terminal 30 has started. If you start accepting comments, proceed to S2.
　Ｓ２：配信サーバ１０は、当選フラグを付与すべきタイミングは否かを判定する。選フラグを付与すべきタイミングである場合、Ｓ３へ進む。当選フラグ発生のタイミングは、例えば上述の（１）～（３）である。 S2: The distribution server 10 determines whether or not it is time to add the winning flag. If it is time to add the selection flag, the process proceeds to S3. The timing of the winning flag generation is, for example, (1) to (3) described above.
　Ｓ３：配信サーバ１０は、タイムライン上のコメントに対して当選フラグを付与する当選フラグ付与処理を実行する。図３～５に示されたように、例えば当選フラグが発生した同時のタイミングで書き込まれたコメントに当選フラグを付与する。同時のタイミングで書き込まれたコメントがない場合は、当選フラグが発生したタイミングの一つ前又は次のコメントを書き込みしたコメントに当選フラグ（即ち、コメントボーナス獲得権）を付与する。 S3: The distribution server 10 executes a winning flag giving process for giving a winning flag to a comment on the timeline. As shown in FIGS. 3 to 5, for example, a winning flag is given to a comment written at the same time when the winning flag is generated. If there are no comments written at the same timing, the winning flag (that is, the right to acquire the comment bonus) is given to the comment that wrote the comment immediately before or after the timing when the winning flag was generated.
　Ｓ４：配信サーバ１０は、各々の視聴者端末３０からのコメント受付を終了したか否かを判定する。コメント受付を終了した場合、ＥＮＤへ進み、コメント受付を終了しない場合、再びＳ２へ進む。 S4: The distribution server 10 determines whether or not the comment reception from each viewer terminal 30 has been completed. If the comment reception is finished, the process proceeds to END, and if the comment reception is not finished, the process proceeds to S2 again.
