＜１．遠隔映像配信システム＞
　図１および図２を用いて、実施形態の一例である遠隔映像配信システム１０について説明する。 <1. Remote video distribution system＞
A remote video distribution system 10, which is an example of an embodiment, will be described using FIGS. 1 and 2.
　図１に示すように、遠隔映像配信システム１０は、エレベーター２０のかご室２１または乗場２２に設けられ、利用客に向けてコンテンツを表示する複数の表示装置１１と、それぞれの表示装置１１に通信回線１２を介してコンテンツを配信する遠隔映像配信サーバ５０とを有する。遠隔映像配信システム１０によれば、詳細は後述するが、通信コストを低減しつつエレベーター２０の利用客へのコンテンツの配信サービスの品質を維持することができる。 As shown in FIG. 1, the remote video distribution system 10 is provided in a car room 21 or a landing 22 of an elevator 20, and communicates with a plurality of display devices 11 for displaying content for passengers, and for each display device 11. It has a remote video distribution server 50 that distributes content via the line 12. According to the remote video distribution system 10, the details will be described later, but the quality of the content distribution service to the customers of the elevator 20 can be maintained while reducing the communication cost.
　本実施形態のエレベーター２０は、乗用エレベーターであって、主に利用客の輸送を目的とする。本実施形態のエレベーター２０が設置される建物１３には、共同住宅、事務所、商業施設、宿泊施設、医療施設等が含まれる。 The elevator 20 of this embodiment is a passenger elevator, and is primarily intended for transporting passengers. The building 13 in which the elevator 20 of this embodiment is installed includes an apartment complex, an office, a commercial facility, an accommodation facility, a medical facility, and the like.
　表示装置１１は、遠隔映像配信サーバ５０から配信されたコンテンツを表示する。コンテンツとは、映像データに基づく情報の内容であって、広告、ニュース、天気予報等が含まれる。広告は、エレベーター２０が商業施設に設置されている場合には、商業施設内のテナントの広告であってもよい。また、広告は、一般のＴＶで放映されるＣＭであってもよい。 The display device 11 displays content distributed from the remote video distribution server 50.

If the elevator 20 is installed in a commercial facility, the advertisement may be an advertisement for a tenant in the commercial facility. Further, the advertisement may be a commercial aired on general TV.
　本実施形態の遠隔映像配信システム１０では、複数の表示装置１１を有する構成としたが、１つの表示装置１１のみを有する構成であってもよい。本実施形態の表示装置１１には、かご室表示装置３０および乗場表示装置４０が含まれている。以下、かご室表示装置３０および乗場表示装置４０の両方を指す場合には、単に表示装置１１と記載する。 Although the remote video distribution system 10 of this embodiment has a configuration having a plurality of display devices 11, it may have a configuration having only one display device 11. The display device 11 of this embodiment includes a car room display device 30 and a hall display device 40. Hereinafter, when both the car room display device 30 and the hall display device 40 are referred to, they will simply be referred to as the display device 11.
　かご室表示装置３０は、エレベーター２０のかご室２１に設けられている。かご室表示装置３０は、かご室２１内の利用客に向けてコンテンツを表示する。かご室表示装置３０について詳細は後述する。乗場表示装置４０は、エレベーター２０の乗場２２に設けられている。乗場表示装置４０は、乗場２２で配車待ちの利用客に向けてコンテンツを表示する。乗場表示装置４０について詳細は後述する。 The cab display device 30 is provided in the cab 21 of the elevator 20. The car room display device 30 displays content to the passengers in the car room 21. Details of the cage display device 30 will be described later. The hall display device 40 is provided in the hall 22 of the elevator 20. The hall display device 40 displays content for passengers waiting to be dispatched at the hall 22. Details of the hall display device 40 will be described later.
　遠隔映像配信サーバ５０は、複数のエレベーター２０のそれぞれに設けられた表示装置１１に通信回線１２を介してコンテンツを配信する。本実施形態の遠隔映像配信サーバ５０は、エレベーター２０の管理会社が所有している。本実施形態の遠隔映像配信サーバ５０は、複数の建物１３にそれぞれ設置されたエレベーター２０の表示装置１１にコンテンツを配信する。遠隔映像配信サーバ５０について詳細は後述する。 The remote video distribution server 50 distributes content to the display devices 11 provided in each of the plurality of elevators 20 via the communication line 12. The remote video distribution server 50 of this embodiment is owned by the management company of the elevator 20. The remote video distribution server 50 of this embodiment distributes content to the display devices 11 of the elevators 20 installed in each of the plurality of buildings 13. Details of the remote video distribution server 50 will be described later.

The communication line 12 of this embodiment is a general communication line, and includes a telephone line, a data communication line, and an Internet line.
　ところで、通信回線１２の使用料金パターンとして、所定期間において、データ通信量が基本データ通信量以下の場合には、料金が一律であって、データ通信量が基本データ通信量を超えた場合には、データ通信速度が低下する、または使用料金が増額される場合がある。そのため、基本データ通信量よりも低いデータ通信量として所定データ通信量を設定し、データ通信量が所定データ通信量を超えた際に、優先度の低いコンテンツの配信を停止する、コンテンツの配信頻度を少なくする等の対策によって通信コストを低減している。しかし、通信コストを低減しようとすると、エレベーター２０の利用客に提供するサービスの品質が低下することになる。 By the way, the usage fee pattern for the communication line 12 is that if the amount of data communication is less than the basic amount of data communication during a predetermined period, the fee is flat, and if the amount of data communication exceeds the basic amount of data communication, the fee is fixed. , data communication speed may be reduced, or usage charges may increase. Therefore, the content distribution frequency is such that a predetermined data communication amount is set as a lower data communication amount than the basic data communication amount, and when the data communication amount exceeds the predetermined data communication amount, distribution of low-priority content is stopped. Communication costs are being reduced by measures such as reducing the amount of data. However, if an attempt is made to reduce communication costs, the quality of the service provided to customers using the elevator 20 will deteriorate.
　そこで、本実施形態の遠隔映像配信システム１０では、詳細は後述するが、それぞれの表示装置１１のコンテンツの配信効果を算出して配信効果が低い表示装置１１へのデータ通信量を減少させることによって、通信コストを低減しつつエレベーター２０の利用客へのコンテンツの配信サービスの品質を維持することができる。 Therefore, in the remote video distribution system 10 of this embodiment, the details will be described later, but by calculating the distribution effect of the content of each display device 11 and reducing the amount of data communication to the display device 11 with a low distribution effect. , it is possible to maintain the quality of the content distribution service to the customers using the elevator 20 while reducing communication costs.

＜４－２．配信効果算出部＞
　配信効果算出部６２は、それぞれの表示装置１１によるコンテンツの配信効果を算出する。本実施形態の配信効果算出部６２は、かご室２１または乗場２２の利用客の有無に基づいて配信効果を算出する。 <4-2. Distribution effect calculation department＞
The distribution effect calculation unit 62 calculates the distribution effect of content by each display device 11. The distribution effect calculation unit 62 of this embodiment calculates the distribution effect based on the presence or absence of passengers in the car room 21 or the landing hall 22.
　配信効果算出部６２は、かご室表示装置３０によってコンテンツを表示している時間における、かご室２１内に利用客が存在する時間の割合を配信効果とする。当該割合が高い場合は、配信効果が高く、当該割合が低い場合は、配信効果が低い。かご室２１内に利用客が存在する時間は、上述した人感センサ２５によってかご室２１に利用客が存在することを検知した時間に基づいて算出する。 The distribution effect calculation unit 62 determines the distribution effect as the ratio of the time when the passenger is present in the car room 21 during the time when the content is displayed on the car room display device 30. When the ratio is high, the distribution effect is high, and when the ratio is low, the distribution effect is low. The time during which the passenger is present in the car room 21 is calculated based on the time when the presence of the passenger in the car room 21 is detected by the human sensor 25 described above.
　また、配信効果算出部６２は、乗場表示装置４０によってコンテンツを表示している時間における、乗場２２に利用客が存在する時間の割合を配信効果とする。当該割合が高い場合は、配信効果が高く、当該割合が低い場合は、配信効果が低い、乗場２２に利用客が存在する時間は、上述した人感センサ２６によって乗場２２に利用客が存在することを検知した時間に基づいて算出する。 Furthermore, the distribution effect calculation unit 62 determines as the distribution effect the ratio of the time when passengers are present in the hall 22 during the time when the content is displayed on the hall display device 40. When the ratio is high, the distribution effect is high, and when the ratio is low, the distribution effect is low.During the time when there are passengers in the hall 22, the presence of passengers in the hall 22 is detected by the human sensor 26 described above. Calculated based on the time when this was detected.
　実施形態の他の一例として、配信効果算出部６２は、かご室２１または乗場２２の利用客の人数に基づいてコンテンツの配信効果を算出してもよい。 As another example of the embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of the content based on the number of passengers in the car room 21 or the landing area 22.
　例えば、配信効果算出部６２は、かご室表示装置３０によってコンテンツを配信している時間における、かご室２１内の利用客の人数を配信効果としてもよい。具体的には、コンテンツを配信している時間と利用客との積を配信効果として算出してもよい。当該積が大きいほど配信効果が高く、当該積が小さいほど配信効果が低い。かご室２１内の利用客の人数は、かご室２１に設けられたカメラによってかご室２１の利用客を撮影し、撮影した画像を解析することによって算出してもよい。 For example, the distribution effect calculation unit 62 may take the number of passengers in the car room 21 during the time that the content is being distributed by the car room display device 30 as the distribution effect. Specifically, the product of the time that the content is being distributed and the number of passengers may be calculated as the distribution effect. The larger the product, the higher the distribution effect, and the smaller the product, the lower the distribution effect. The number of passengers in the car room 21 may be calculated by photographing the passengers in the car room 21 with a camera installed in the car room 21 and analyzing the photographed image.
　また、配信効果算出部６２は、乗場表示装置４０によってコンテンツを配信している時間における乗場２２の配車待ちの利用客の人数を配信効果としてもよい。具体的には、コンテンツを配信している時間と利用客との積を配信効果として算出してもよい。当該積が大きいほど配信効果が高く、当該積が小さいほど配信効果が低い。乗場２２の利用客の人数は、乗場２２に設けられたカメラによって乗場２２の利用客を撮影し、撮影した画像を解析することによって算出してもよい。 Furthermore, the distribution effect calculation unit 62 may use the number of passengers waiting to be dispatched at the hall 22 at the time when the content is being distributed by the hall display device 40 as the distribution effect. Specifically, the product of the content distribution time and the number of users may be calculated as the distribution effect. The larger the product, the higher the distribution effect, and the smaller the product, the lower the distribution effect. The number of passengers in the hall 22 may be calculated by photographing the passengers in the hall 22 with a camera provided in the hall 22 and analyzing the photographed images.
　なお、エレベーター２０の利用客の人数は、かご室２１または乗場２２に設けられたカメラによって撮影された画像を解析することによって算出する手段に限定されることなく、行先予報システムの登録履歴、かご秤装置によって算出してもよい。行先予報システムとは、乗車前に行先階を登録することによって同じ行先階の利用者を同じエレベーター２０へ案内して運行を効率的にするシステムである。 Note that the number of passengers in the elevator 20 is not limited to the method of calculating by analyzing images taken by a camera installed in the car room 21 or the landing 22; It may also be calculated using a weighing device. The destination forecast system is a system that guides users on the same destination floor to the same elevator 20 by registering the destination floor before boarding, thereby making the operation more efficient.
　実施形態の他の一例として、配信効果算出部６２は、利用客がコンテンツを視認したかどうかを間接的に確認してコンテンツの配信効果を算出してもよい。 As another example of the embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of the content by indirectly checking whether the customer has viewed the content.
　例えば、エレベーター２０と利用客のスマートフォンとが連動しているシステムにおいて、表示装置１１によって表示されるコンテンツとスマートフォンのコンテンツとが連動している場合には、利用客がスマートフォンのコンテンツをクリックした回数が少ない表示装置１１について配信効果が低いと算出してもよく、スマートフォンのコンテンツをクリックした回数が多い表示装置１１について配信効果が高いと算出してもよい。 For example, in a system where the elevator 20 and the customer's smartphone are linked, if the content displayed by the display device 11 and the content on the smartphone are linked, the number of times the customer clicks on the content on the smartphone It may be calculated that the distribution effect is low for the display device 11 with a small number of clicks, or it may be calculated that the distribution effect is high for the display device 11 that has a large number of clicks on the smartphone content.
　また、配信効果算出部６２は、かご室２１または乗場２２の利用客が表示装置１１に表示されたＱＲコード（登録商標）が読み込まれた回数に基づいてコンテンツの配信効果を算出してもよい。例えば、ＱＲコードが読み込まれた回数が少ない表示装置１１について配信効果が低いと算出してもよく、ＱＲコードが読み込まれた回数が多い表示装置１１について配信効果が高いと算出してもよい。 Further, the distribution effect calculation unit 62 may calculate the distribution effect of the content based on the number of times a QR code (registered trademark) displayed on the display device 11 is read by a passenger in the car room 21 or the landing 22. . For example, it may be calculated that the distribution effect is low for the display device 11 whose QR code is read a small number of times, and it may be calculated that the distribution effect is high for the display device 11 whose QR code is read a large number of times.
　実施形態の他の一例として、配信効果算出部６２は、エレベーター２０の稼働率に基づいてコンテンツの配信効果を算出してもよい。例えば、配信効果算出部６２は、稼働率の低いエレベーター２０の表示装置１１について配信効果が低いと算出してもよく、稼働率の高いエレベーター２０の表示装置１１について配信効果が高いと算出してもよい。また、配信効果算出部６２は、エレベーター２０の時間帯毎の稼働率を集計し、稼働率が低い時間帯について配信効果が低いと算出し、稼働率が高い時間帯について配信効果が高いと算出してもよい。 As another example of the embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of the content based on the operating rate of the elevator 20. For example, the distribution effect calculation unit 62 may calculate that the display device 11 of the elevator 20 with a low utilization rate has a low distribution effect, and may calculate that the display device 11 of an elevator 20 with a high utilization rate has a high distribution effect. Good too. Furthermore, the distribution effect calculation unit 62 aggregates the operation rate of the elevator 20 for each time period, calculates that the distribution effect is low in the time period with a low operation rate, and calculates that the distribution effect is high in a time period with a high operation rate. You may.
　実施形態の他の一例として、配信効果算出部６２は、コンテンツの表示回数または表示時間に基づいてコンテンツの配信効果を算出してもよい。ここで、表示装置１１では、通常のコンテンツの表示以外に、エレベーター２０の運行に関する割り込みコンテンツが表示される場合がある。割り込みコンテンツとは、例えば、エレベーター２０の利用状況に対する警告コンテンツ、利用者の属性による利用方法の啓蒙コンテンツ等が挙げられる。 As another example of the embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of the content based on the number of times the content is displayed or the display time of the content. Here, in addition to displaying normal content, the display device 11 may display interrupt content regarding the operation of the elevator 20. Interruption content includes, for example, warning content regarding the usage status of the elevator 20, educational content on how to use the elevator 20 based on user attributes, and the like.
　例えば、割り込みコンテンツが多く、通常のコンテンツの表示回数または表示時間が少ないエレベーター２０の表示装置１１について配信効果が低いと算出してもよい。また、割り込みコンテンツが少なく、通常のコンテンツの表示回数または表示時間が多いエレベーター２０の表示装置１１について配信効果が高いと算出してもよい。 For example, it may be calculated that the distribution effect is low for the display device 11 of the elevator 20 where there are many interruption contents and the number of times or display time of normal contents is small. Alternatively, it may be calculated that the display device 11 of the elevator 20 has a high distribution effect with a small number of interruption contents and a large number of times or display time of normal contents.
　実施形態の他の一例として、配信効果算出部６２は、かご室２１または乗場２２の利用客が表示装置１１を視認している時間に基づいてコンテンツの配信効果を算出してもよい。例えば、利用客が表示装置１１を視認している時間が少ないエレベーター２０の表示装置１１について配信効果が低いと算出してもよく、利用客が表示装置１１を視認している時間が多いエレベーター２０の表示装置１１について配信効果が高いと算出してもよい。表示装置１１を視認している時間は、かご室２１または乗場２２に設けられたカメラによって撮影された画像を解析して、利用客の目線を検知することによって算出してもよい。 As another example of the embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of the content based on the time during which the passengers in the car room 21 or the landing hall 22 view the display device 11. For example, it may be calculated that the distribution effect is low for the display device 11 of the elevator 20 where customers spend less time viewing the display device 11, and for the elevator 20 where the customer spends more time viewing the display device 11. It may be calculated that the distribution effect is high for the display device 11 of . The time during which the display device 11 is viewed may be calculated by analyzing an image taken by a camera installed in the car room 21 or the landing hall 22 and detecting the passenger's line of sight.
＜４－３．データ通信量制御部＞
　データ通信量制御部６３は、所定期間において、データ通信量が第１データ通信量以上になった場合に、配信効果算出部６２によって算出された配信効果が低い表示装置１１へのデータ通信量を減少させる。ここで、第１データ通信量は、上述した基本データ通信量より低く設定されたものである。データ通信量を減少させる手段としては、配信するコンテンツ数または種類を少なくする、配信するコンテンツのデータサイズを小さくする、優先度の低いコンテンツの配信を停止する、コンテンツの配信頻度を少なくする、配信するコンテンツのエンコードの仕様または条件を変更する等が好ましい。 <4-3. Data communication amount control section>
The data communication amount control section 63 controls the amount of data communication to the display device 11 having a low distribution effect calculated by the distribution effect calculation section 62 when the amount of data communication exceeds the first amount of data communication during a predetermined period. reduce Here, the first data communication amount is set lower than the basic data communication amount described above. Measures to reduce the amount of data communication include reducing the number or type of content to be distributed, reducing the data size of the content to be distributed, stopping the distribution of low-priority content, reducing the frequency of content distribution, It is preferable to change the encoding specifications or conditions of the content.
　これにより、データ通信量が第１データ通信量以上となって基本データ通信量まで余裕がない場合には、それぞれの表示装置１１のコンテンツの配信効果を算出して配信効果の低い表示装置１１へのデータ通信量を減少させることによって、通信コストを低減することができる。また、コンテンツの配信効果の低い表示装置１１へのデータ通信量を減少させるため、エレベーター２０の利用客へのコンテンツの配信サービスの品質を損なうことはない。 As a result, if the data communication amount exceeds the first data communication amount and there is not enough room to reach the basic data communication amount, the content distribution effect of each display device 11 is calculated and the content is transferred to the display device 11 with the lower distribution effect. By reducing the amount of data communication, communication costs can be reduced. Further, since the amount of data communication to the display device 11, which has a low content distribution effect, is reduced, the quality of the content distribution service to the customers of the elevator 20 is not impaired.
　一方、データ通信量制御部６３は、所定期間において、データ通信量が第２データ通信量未満の場合に、配信効果算出部６２によって算出された配信効果が高い表示装置１１へのデータ通信量を増加させる。データ通信量を増加させる手段としては、配信するコンテンツ数または種類を多くする、配信するコンテンツのデータサイズを大きくする、コンテンツの配信頻度を多くする、配信するコンテンツのエンコードの仕様または条件を変更する等が好ましい。なお、第２データ通信量は、第１データ通信量よりも少ない量である。 On the other hand, if the data communication amount is less than the second data communication amount during the predetermined period, the data communication amount control unit 63 controls the data communication amount to the display device 11 having a high distribution effect calculated by the distribution effect calculation unit 62. increase. Measures to increase data communication include increasing the number or types of distributed content, increasing the data size of distributed content, increasing the frequency of content distribution, and changing the encoding specifications or conditions of distributed content. etc. are preferred. Note that the second data communication amount is smaller than the first data communication amount.
　これにより、データ通信量が第２データ通信量未満であって基本データ通信量まで余裕がある場合には、それぞれの表示装置１１のコンテンツの配信効果を算出して配信効果の高い表示装置１１へのデータ通信量を増加させることによって、エレベーター２０の利用客へのコンテンツの配信サービスの品質を向上させることができる。 As a result, if the data communication amount is less than the second data communication amount and there is enough room to reach the basic data communication amount, the distribution effect of the content of each display device 11 is calculated and the content is distributed to the display device 11 with the highest distribution effect. By increasing the amount of data communication, it is possible to improve the quality of the content distribution service to the customers using the elevator 20.
　本実施形態のデータ通信量制御部６３は、所定期間において、データ通信量が第２データ通信量以上になった場合に、配信効果算出部６２によって算出された配信効果が低い表示装置１１へのデータ通信量を減少させ、データ通信量が所定データ通信量未満の場合に、配信効果算出部６２によって算出された配信効果が高い表示装置１１へのデータ通信量を増加させる構成としたが、配信効果が低い表示装置１１へのデータ通信量を減少させるのみの構成でもよく、配信効果が高い表示装置１１へのデータ通信量を増加させる構成であってもよい。 The data communication amount control unit 63 of the present embodiment controls the display device 11 that has a low distribution effect calculated by the distribution effect calculation unit 62 when the data communication amount exceeds the second data communication amount in a predetermined period. Although the configuration is such that the amount of data communication is decreased, and when the amount of data communication is less than a predetermined amount of data communication, the amount of data communication is increased to the display device 11 having a high distribution effect calculated by the distribution effect calculation unit 62, It may be a configuration that only reduces the amount of data communication to the display device 11 that has a low distribution effect, or a configuration that increases the amount of data communication to the display device 11 that has a high distribution effect.
　実施形態の他の一例として、データ通信量制御部６３は、データ通信量を減少させる手段として、表示装置１１にメモリを設け、事前に遠隔映像配信サーバ５０によって配信されたコンテンツをメモリに保存し、メモリに保存されたコンテンツを配信してもよい。この場合には、データ通信量に余裕がある間に遠隔映像配信サーバ５０によってコンテンツを配信して保存しておくことが好ましい。 As another example of the embodiment, the data communication amount control unit 63 provides a memory in the display device 11 and stores content distributed by the remote video distribution server 50 in advance in the memory as a means for reducing the amount of data communication. , content stored in memory may be distributed. In this case, it is preferable that the remote video distribution server 50 distributes and stores the content while there is enough data communication.
　実施形態の他の一例として、データ通信量制御部６３は、災害が発生した場合には、災害発生地域の建物１３の表示装置１１へのデータ通信量を増加させて、その他の地域の建物１３の表示装置１１へのデータ通信量を減少させてもよい。これにより、災害時の災害地域のデータ通信量を確保することができる。 As another example of the embodiment, when a disaster occurs, the data communication amount control unit 63 increases the amount of data communication to the display device 11 of the building 13 in the disaster area, and increases the amount of data communication to the display device 11 of the building 13 in the disaster area. The amount of data communication to the display device 11 may be reduced. This makes it possible to secure the amount of data communication in the disaster area during a disaster.
＜５．データ通信量制御＞
　図４を用いて、遠隔映像配信システム１０のデータ通信量制御の流れについて説明する。 <5. Data traffic control>
The flow of data communication amount control of the remote video distribution system 10 will be explained using FIG. 4.
　図４に示すように、ステップＳ１１において、遠隔映像配信サーバ５０のデータ通信量算出部６１は、遠隔映像配信システム１０全体のデータ通信量の加算を開始する。ステップＳ１２において、遠隔映像配信システム１０全体のデータ通信量が第１データ通信量以上かどうかを確認し、第１データ通信量以上の場合には、基本データ通信量まで余裕がないため、ステップＳ１３に移行し、第１データ通信量未満の場合には、ステップＳ１５に移行する。 As shown in FIG. 4, in step S11, the data communication amount calculation unit 61 of the remote video distribution server 50 starts adding up the data communication amount of the entire remote video distribution system 10. In step S12, it is checked whether the data communication amount of the entire remote video distribution system 10 is equal to or greater than the first data communication amount, and if it is the first data communication amount or more, there is not enough room for the basic data communication amount, so step S13 If the amount of data communication is less than the first data communication amount, the process moves to step S15.
　ステップＳ１３において、遠隔映像配信サーバ５０の配信効果算出部６２は、遠隔映像配信システム１０のそれぞれの表示装置１１のコンテンツの配信効果を算出する。ステップＳ１４において、遠隔映像配信サーバ５０のデータ通信量制御部６３は、配信効果が低い表示装置１１へのデータ通信量を減少させて、ステップＳ１８へ移行する。 In step S13, the distribution effect calculation unit 62 of the remote video distribution server 50 calculates the distribution effect of the content on each display device 11 of the remote video distribution system 10. In step S14, the data communication amount control unit 63 of the remote video distribution server 50 reduces the amount of data communication to the display device 11, which has a low distribution effect, and proceeds to step S18.
　ステップＳ１５において、遠隔映像配信システム１０全体のデータ通信量が第２データ通信量未満かどうかを確認し、第２データ通信量未満の場合には、基本データ通信量まで余裕があるため、ステップＳ１６に移行し、第２所定データ通信量以上の場合には、ステップＳ１８に移行する（特に、データ通信量の減少または増加させることなく通常モードとする）。ステップＳ１６において、遠隔映像配信サーバ５０の配信効果算出部６２は、遠隔映像配信システム１０のそれぞれの表示装置１１のコンテンツの配信効果を算出する。ステップＳ１７において、遠隔映像配信サーバ５０のデータ通信量制御部６３は、配信効果が高い表示装置１１へのデータ通信量を増加させて、ステップＳ１８へ移行する。 In step S15, it is checked whether the data communication amount of the entire remote video distribution system 10 is less than the second data communication amount, and if it is less than the second data communication amount, there is a margin up to the basic data communication amount, so step S16 If the amount of data communication is equal to or greater than the second predetermined amount, the process proceeds to step S18 (in particular, the normal mode is set without reducing or increasing the amount of data communication). In step S16, the distribution effect calculation unit 62 of the remote video distribution server 50 calculates the distribution effect of the content on each display device 11 of the remote video distribution system 10. In step S17, the data communication amount control unit 63 of the remote video distribution server 50 increases the amount of data communication to the display device 11 that has a high distribution effect, and proceeds to step S18.
　ステップＳ１８において、遠隔映像配信サーバ５０のデータ通信量算出部６１は、所定期間が経過したかを確認する。所定期間が経過した場合には、ステップＳ１９に移行する。ステップＳ１９において、遠隔映像配信サーバ５０のデータ通信量算出部６１は、データ通信量をリセットする。 In step S18, the data communication amount calculation unit 61 of the remote video distribution server 50 checks whether a predetermined period of time has elapsed. If the predetermined period has elapsed, the process moves to step S19. In step S19, the data communication amount calculation unit 61 of the remote video distribution server 50 resets the data communication amount.
＜６．効果＞
　遠隔映像配信システム１０によれば、通信コストを低減しつつエレベーター２０の利用客へのコンテンツの配信サービスの品質を維持することができる。より具体的には、データ通信量がいわゆる料金が一律である基本データ通信量よりも低く設定された第１データ通信量以上の場合には、コンテンツの配信効果が低い表示装置１１へのデータ通信量を減少させることによって、できるだけ基本データ通信量を超えないようにしている。これにより、通信コストを低減させることができる。また、コンテンツの配信効果の低い表示装置１１へのデータ通信量を減少させるため、エレベーター２０の利用客へのコンテンツの配信サービスの品質を損なうことはない。 <6. Effect>
According to the remote video distribution system 10, the quality of the content distribution service to the customers of the elevator 20 can be maintained while reducing communication costs. More specifically, if the data communication amount is equal to or greater than the first data communication amount, which is set lower than the basic data communication amount for which the fee is uniform, the data communication to the display device 11 with low content distribution effect is performed. By reducing the amount, we are trying to avoid exceeding the basic data communication amount as much as possible. Thereby, communication costs can be reduced. Further, since the amount of data communication to the display device 11, which has a low content distribution effect, is reduced, the quality of the content distribution service to the customers of the elevator 20 is not impaired.
　また、データ通信量が第２データ通信量未満の場合には、基本データ通信量を超えるまでに余裕があるため、コンテンツの配信効果が高い表示装置１１へのデータ通信量を増加させることによって、コンテンツの配信サービスの品質を向上させることができる。 Furthermore, if the amount of data communication is less than the second amount of data communication, there is some margin before it exceeds the basic amount of data communication, so by increasing the amount of data communication to the display device 11 that has a high content distribution effect, The quality of content distribution service can be improved.
