Description

音響信号出力システムAcoustic signal output system
　本発明は、放送音源に情報を付加して出力する音響信号出力システムに関するものである。 The present invention relates to an acoustic signal output system for adding information to a broadcast sound source and outputting the information.
　テレビ放送において、番組の放送にデータ放送を重畳して、文字や音を出力する技術が実用化されている。そのため、テレビ番組を視聴しながら番組表や天気予報を表示出来るようになった。 In television broadcasting, a technology for superimposing data broadcasting on program broadcasting and outputting characters and sounds has been put into practical use. Therefore, it is now possible to display the program guide and weather forecast while watching TV programs.
　しかし、データ放送では、テレビ画面内での番組表の表示や、視聴中の番組情報を参照する等、付加されたデータの利用がテレビを介したものに留っていた。そして、より詳細な情報を入手するには、携帯端末やコンピュータを用いてインターネットを利用し、検索を行う他なかった。 However, in data broadcasting, the use of the added data, such as displaying the program guide on the TV screen and referring to the program information being watched, has been limited to those via the TV. And in order to obtain more detailed information, there was no other way than searching using the Internet using a portable terminal or a computer.
　また、撮影を行った場所や、出演者の着ている服など、番組中にごく僅かな時間だけ映し出される対象に関する情報は、データ放送では提供しきれておらず、ドラマ番組のあらすじ等、番組全体を説明する情報が提供されるに留まっていた。 In addition, information on subjects that are projected for a very short time during the program, such as the location where the photo was taken, the clothes worn by the performers, etc., cannot be provided by data broadcasting. Only the information explaining the whole was provided.
　そこで特許文献１のように、テレビ番組の放送音源に重畳された識別情報と、データベースに記録された識別情報／放送時間テーブルと、視聴者の携帯端末とを用いて、視聴中の番組に関する細かな情報を携帯端末上で閲覧可能とする発明が公開された。 Therefore, as disclosed in Patent Document 1, using the identification information superimposed on the broadcast sound source of the TV program, the identification information / broadcast time table recorded in the database, and the viewer's mobile terminal, details about the program being viewed are detailed. An invention that makes it possible to view various information on a mobile terminal has been released.
　この発明は、音響信号システムに関するものである。製作者側は、対象のＷＥＢページにアクセスするための識別情報を、音響信号に変換してテレビの放送音源に重畳させ、出力する。音響信号は、人間には聞こえない周波数を利用しているため、テレビの放送などに重ね合わせ、出力することが可能である。
　ユーザは、携帯端末の集音部とアプリケーションを利用して、放送された重畳音響内から識別情報を抽出・復元してサーバへ送信する。サーバは、送られてきた識別情報に対応したＵＲＬを携帯端末に返送することで、ユーザにそのＵＲＬを提供することが可能である。 The present invention relates to an acoustic signal system. The producer side converts the identification information for accessing the target WEB page into an acoustic signal, superimposes it on the broadcast sound source of the television, and outputs it. Since the acoustic signal uses a frequency that cannot be heard by humans, it can be superimposed and output on a television broadcast or the like.
The user extracts and restores the identification information from the broadcast superimposed sound using the sound collection unit and the application of the mobile terminal, and transmits it to the server. The server can provide the URL to the user by returning the URL corresponding to the sent identification information to the portable terminal.
　こうしたインターネット内外どちらか一方から、他方での行動・購買に影響を与えるような政策をＯ２Ｏ（Online to Offline）という。前述の音響を用いた音響信号システムはテレビ放送だけに限ったものではなく、実店舗においても、店内放送用などに備えられたスピーカーから音響信号を出力することでＯ２Ｏが実施されている。特許文献２には、メモリに保存された識別情報を音響信号に変換し、店舗内に放送する音源に重畳して出力する音響信号出力装置に関しての記載がある。 “O2O (Online Offline)” refers to a policy that affects the behavior and purchasing of either the inside or outside of the Internet. The above-described acoustic signal system using sound is not limited to television broadcasting, and O2O is performed by outputting an acoustic signal from a speaker provided for in-store broadcasting in an actual store. Patent Document 2 describes an acoustic signal output device that converts identification information stored in a memory into an acoustic signal and outputs the acoustic signal by superimposing it on a sound source broadcast in a store.

　音響信号システムを利用することで、テレビ番組内の詳細な情報を視聴者に発信することができ、テレビ画面を見るだけで完結していた視聴者をインターネットサイトに誘導することが可能となった。また、テレフォンショッピングなどで商品を購入したい際には、電話をかけたり、アドレスの入力やキーワード検索をしたりする必要がなくなり、視聴者を購入ウェブページにスムーズに誘導することが可能となった。
　また、音響信号出力装置を用いて、電子クーポンやポイントの配布を店頭で行うことが可能となり、実店舗への集客と購買行動分析を一挙に行うことが出来るようになった。 By using the sound signal system, it is possible to send detailed information in TV programs to viewers, and it is now possible to guide viewers who have been completed just by watching TV screens to the Internet site. . In addition, it is no longer necessary to make a phone call, enter an address, or perform a keyword search when purchasing a product through telephone shopping, etc., and it is now possible to guide viewers to the purchase web page smoothly. .
In addition, it is possible to distribute electronic coupons and points at stores using an acoustic signal output device, and it is now possible to collect customers and analyze purchasing behavior at a single store.
　しかしながら、音響を用いて情報提供を行う際にもいくつか問題点が挙げられる。 However, there are some problems when providing information using sound.
　まず、前もって識別情報の音響信号化や、重畳作業を行う必要がある点である。前もって識別情報ごとの音響信号や重畳音響を作成し、ＣＤ（Compact Disc）などの記録媒体に記録して使用する必要があるため、長時間の事前準備と作業機材が必要になってしまう。加えて、作成した音響信号・重畳音響の保存や配布といった煩雑な作業が発生する。
　また、音響信号出力装置を使用する際には、前もって音響信号出力装置の記憶部に識別情報を記憶させておく必要があり、識別情報を変更する際には、再度記憶部の書き換え設定を行わなくてはならない。 First, it is necessary to convert the identification information into an acoustic signal and perform superimposing work in advance. Since it is necessary to create an acoustic signal or superimposed sound for each piece of identification information in advance and record and use it on a recording medium such as a CD (Compact Disc), long preparations and work equipment are required. In addition, complicated work such as storage and distribution of the created acoustic signal / superimposed sound occurs.
Also, when using the acoustic signal output device, it is necessary to store the identification information in the storage unit of the acoustic signal output device in advance, and when changing the identification information, rewrite setting of the storage unit is performed again. Must-have.
　次に、番組の放送時間に変動が起こった際、対応する識別情報／放送時間テーブルを変更することが出来ない点である。既存の音響信号システムは、受け取った識別情報に対して返送するコンテンツと、返送するコンテンツの変更を行う時刻と、を対応させた識別情報／放送時間テーブルを持っており、携帯端末から識別情報が送信された時刻をもとに返送するコンテンツを変更することで、単一の識別情報であっても、異なったコンテンツをユーザに配信可能にするものである。テレビ番組のように放送音源の出力時刻に変動の起こらない対象に対しては有効であるが、ライブイベントのように大まかなタイムスケジュールしか決定しておらず、重畳対象の音源の放音時刻に変動が生じる可能性のある場合、既存のシステムでは対応しきれない。時刻を変更する際は、データベース内のコンテンツタイムテーブルを変更したり、識別情報／コンテンツ対応表を書き換える等、複雑な作業が必要となる。 Next, when the program broadcast time fluctuates, the corresponding identification information / broadcast time table cannot be changed. The existing acoustic signal system has an identification information / broadcasting time table that associates the content to be returned to the received identification information with the time at which the content to be returned is changed, and the identification information is received from the mobile terminal. By changing the content to be returned based on the transmitted time, different contents can be distributed to the user even with a single piece of identification information. Effective for targets that do not cause fluctuations in the output time of broadcast sound sources, such as TV programs, but only a rough time schedule has been determined, such as live events, and the sound output time of the sound source to be superimposed is determined. If there is a possibility of fluctuation, the existing system cannot handle it. When changing the time, complicated work such as changing the content time table in the database or rewriting the identification information / content correspondence table is required.
　本発明は上記のような実状に鑑みてなされたものであり、その目的は、前もって音響信号の作成や重畳作業、音響信号出力装置に出力させる識別情報の再設定、といった煩雑な作業を無くし、重畳対象の音源の放音時刻が変動した際にも対応可能である音響信号出力システムを提供することを課題とする。 The present invention has been made in view of the actual situation as described above, and its purpose is to eliminate the cumbersome work of creating and superimposing the acoustic signal in advance, resetting the identification information to be output to the acoustic signal output device, It is an object of the present invention to provide an acoustic signal output system that can cope with a change in sound output time of a sound source to be superimposed.
　上記課題を解決するために、本発明は、音響信号出力装置と、携帯端末と、識別情報サーバと、を備えた音響信号出力システムであって、前記音響信号出力装置は、出力する識別情報を変更可能な操作手段と、識別情報を音響信号に変換する変換部と、音響信号と放送音源を重畳する重畳部を備え、前記携帯端末は、集音部と、集音した重畳音源から音響信号を抽出する抽出部と、抽出された音響信号から識別情報を復元する復元部と、復元された識別情報を識別情報サーバに送信する識別情報送信部を備え、前記識別情報サーバは、識別情報とコンテンツを対応させたデータベース部と、前記携帯端末から送信された識別情報と対応したコンテンツを導出する照合部と、照合部から導出されたコンテンツを前記携帯端末へ送信するコンテンツ送信部と、を備えていることを特徴とする。 In order to solve the above problems, the present invention provides an acoustic signal output system including an acoustic signal output device, a mobile terminal, and an identification information server, wherein the acoustic signal output device outputs identification information to be output. An operation unit that can be changed; a conversion unit that converts identification information into an acoustic signal; and a superposition unit that superimposes the sound signal and a broadcast sound source. An extraction unit that extracts the identification information from the extracted acoustic signal, and an identification information transmission unit that transmits the restored identification information to the identification information server. A database unit corresponding to content, a collation unit for deriving content corresponding to the identification information transmitted from the portable terminal, and a container for transmitting the content derived from the collation unit to the portable terminal Characterized in that it comprises a tool transmitting unit.
　本発明によれば、音響信号出力装置を備えることで、前もって音響信号を作成・重畳しておく必要がなくなり、操作手段によって操作を行うことで、任意のタイミングで出力する識別情報の変更が可能となる。
　そのため、音響信号の事前作成や、音響信号出力装置の設定等の事前準備が必要なくなる。識別情報の変更指示を逐次出すことが出来るため、重畳対象の放音時刻が変動した場合であっても、適切なコンテンツをユーザに提供することが可能となる。 According to the present invention, the provision of the acoustic signal output device eliminates the need to create and superimpose the acoustic signal in advance, and the identification information output at an arbitrary timing can be changed by performing the operation using the operation means. It becomes.
For this reason, it is not necessary to prepare in advance such as creating an acoustic signal and setting an acoustic signal output device. Since the instruction for changing the identification information can be sequentially issued, it is possible to provide appropriate content to the user even when the sound emission time to be superimposed fluctuates.

An identification information / content correspondence table as shown in FIG. 4 is recorded in the database unit 53, and the content collation unit 52 collates the identification information sent thereto with the content collation unit 52 to output appropriate content. It becomes possible. Further, the database unit 53 is connected to the operation unit 3 and can edit the identification information / content correspondence table.
It is preferable that the identification information server includes an automatic change unit that can change the content to be output with respect to the identification information according to time in order to reduce the work of the operator of the operation unit.
　次に図１、図２及び図５を参照しながら、本実施形態における音響情報出力システム実施者側と利用者側との情報のやり取りについて説明する。 Next, the exchange of information between the sound information output system implementer side and the user side in this embodiment will be described with reference to FIGS.
　音響信号出力システム実施者には、識別情報サーバ５を操作するためのＩＤが付与される（Ｓ１）。サーバ操作アプリケーションを備えた操作手段３を用いて、識別情報サーバ５へログインし（Ｓ２）、データベース部５３上の識別情報／コンテンツ対応表を作成する（Ｓ３）。 The ID for operating the identification information server 5 is given to the sound signal output system implementer (S1). Using the operation means 3 having a server operation application, the user logs in to the identification information server 5 (S2), and creates an identification information / content correspondence table on the database unit 53 (S3).
　識別情報／コンテンツ対応表の作成が完了したら、音響信号出力装置１から出力する識別情報／コンテンツを選択し、出力を行う（Ｓ４）。操作手段３によって選択された識別情報は識別情報入力部１３から入力された後、記憶部１５に記憶され、変換部１１によって音響信号へと変換される。変換された音響信号及び音源入力部１２から入力された放送音源は、重畳部１０で１つの音響に重ね合わせられた重畳音源となり、出力部１４によって出力される。出力された重畳音源は、店舗のスピーカー等で流される。 When the creation of the identification information / content correspondence table is completed, the identification information / content output from the acoustic signal output device 1 is selected and output (S4). The identification information selected by the operation means 3 is input from the identification information input unit 13, stored in the storage unit 15, and converted into an acoustic signal by the conversion unit 11. The converted sound signal and the broadcast sound source input from the sound source input unit 12 become a superimposed sound source superimposed on one sound by the superimposing unit 10 and output by the output unit 14. The output superimposed sound source is played through a store speaker or the like.
　一方、音響信号出力システム利用者は、インターネット上からアプリケーションを取得し（Ｓ５）、携帯端末上にインストールしておく。このアプリケーションには、携帯端末４の集音部４１を用いて、重畳された音源から音響信号のみを取り出す抽出部４２と、取り出した音響信号をもとの識別情報に戻す復元部４３と、元に戻した識別情報を識別情報サーバ５へ送信する識別情報送信部４４が備わっている。更に、識別情報送信部４４から送信した識別情報に応じて、識別情報サーバ５から送られてくるＵＲＬ等のコンテンツを受信するコンテンツ受信部４５と、そのコンテンツを利用するための実行部４６を備えている。 On the other hand, the user of the acoustic signal output system acquires the application from the Internet (S5) and installs it on the mobile terminal. In this application, using the sound collection unit 41 of the mobile terminal 4, an extraction unit 42 that extracts only the acoustic signal from the superimposed sound source, a restoration unit 43 that returns the extracted acoustic signal to the original identification information, An identification information transmission unit 44 is provided for transmitting the identification information returned to (2) to the identification information server 5. Furthermore, a content receiving unit 45 that receives content such as a URL sent from the identification information server 5 in accordance with the identification information transmitted from the identification information transmitting unit 44, and an execution unit 46 for using the content. ing.
　利用者は、音響信号出力システム実施店等に行くことで、音響信号出力システムを利用することが可能となる。まず、アプリケーションを起動し（Ｓ６）、放送される重畳音源を集音する（Ｓ７）。そして、識別情報のみを抽出し（Ｓ８）、識別情報サーバ５へ送信する。 The user can use the acoustic signal output system by going to an acoustic signal output system implementation store or the like. First, an application is activated (S6), and a superimposed sound source to be broadcast is collected (S7). Then, only the identification information is extracted (S8) and transmitted to the identification information server 5.
　識別情報サーバ５では、携帯端末３から送信された識別情報を識別情報受信部５１で受信する。そして、送られた識別情報を照合部５２に送り、データベース部５３内の識別情報／コンテンツ対応表と照合し（Ｓ９）、対応したコンテンツをコンテンツ送信部５４から携帯端末４へ返す。 In the identification information server 5, the identification information transmitted from the mobile terminal 3 is received by the identification information receiving unit 51. The sent identification information is sent to the collation unit 52, collated with the identification information / content correspondence table in the database unit 53 (S9), and the corresponding content is returned from the content transmission unit 54 to the portable terminal 4.
　携帯端末４は、コンテンツ受信部４５を用いて識別情報サーバ５から送られてきたコンテンツを受信する。受信したコンテンツを実行部４６へ送ることでコンテンツを利用することが出来る（Ｓ１０）。 The portable terminal 4 receives the content sent from the identification information server 5 using the content receiving unit 45. The content can be used by sending the received content to the execution unit 46 (S10).
　実施者は識別情報サーバへ自由にログインしてデータベースの編集を行い、出力させたい識別情報を自由に選ぶことができるため、システムの迅速な導入と運用が可能になる。
　また、本システムを提供する側も識別情報の情報音源化といった事前準備や、それらを保存しておく必要などがなくなり、負担が軽減される。提供時には、音響信号出力装置とサーバへのアクセスＩＤの配布を行うのみで、少ない労力でシステムの提供・運営を行うことが可能である。
　識別情報を利用するのではなく、ＵＲＬの文字列を直接音響信号に変換して出力してもよい。そうすることでデータベースからコンテンツを返送する必要がなくなり、携帯端末上でＵＲＬを復元し、目的の情報へアクセスすることが可能となる。
　美術館など、放送音響を出力させたくない際は、放送音源を重畳せず音響情報のみを出力してもよい。 Since the practitioner can freely log in to the identification information server, edit the database, and freely select the identification information to be output, the system can be quickly introduced and operated.
In addition, the provision of this system also eliminates the need for advance preparations such as converting the identification information into an information sound source and storing them, thereby reducing the burden. At the time of provision, it is possible to provide and operate the system with little effort by only distributing the access ID to the acoustic signal output device and the server.
Instead of using identification information, a URL character string may be directly converted into an acoustic signal and output. By doing so, it becomes unnecessary to return the content from the database, and it is possible to restore the URL on the mobile terminal and access the target information.
When it is not desired to output broadcast sound, such as an art museum, only the sound information may be output without superimposing the broadcast sound source.
＜実施形態２＞
　図１、図２、図４及び図６を参照しながら本発明の実施形態２について説明する。なお、本説明で上述した実施形態１と基本的に同一の構成要素については、同一の符号を付してその説明を簡略化する。 <Embodiment 2>
A second embodiment of the present invention will be described with reference to FIGS. 1, 2, 4 and 6. FIG. In addition, about the component fundamentally the same as Embodiment 1 mentioned in this description, the same code | symbol is attached | subjected and the description is simplified.
　本実施形態は、出力するコンテンツの変更を、識別情報の変更と、返送コンテンツの変更との二通りで行う例を示す。システムの全体構成は、実施形態１と同様である。 This embodiment shows an example in which the content to be output is changed by changing the identification information and changing the return content. The overall system configuration is the same as that of the first embodiment.
　店舗に設置された音響信号出力装置１を操作可能な操作手段３を用いて、識別情報サーバ５へログインする（Ｓ１１）。店舗に雨が降っているか否かを確認する（Ｓ１２）。 The user logs in to the identification information server 5 using the operation means 3 capable of operating the acoustic signal output device 1 installed in the store (S11). It is confirmed whether or not the store is raining (S12).
　店舗に雨が降っている場合（Ｓ１２でＹ）、音響信号出力装置１の出力する識別情報を変更し、データベース部５３を操作して、図４（ｂ）の識別情報０００２のような雨の日用のクーポンを出力するよう設定する（Ｓ１３）。店舗に雨が降っていない場合は（Ｓ１２でＮ）、図４（ｂ）の識別情報０００１のような通常時のクーポンの配布を行う（Ｓ１４）。そして、決定した識別情報を音響信号出力装置１から出力させる（Ｓ１５）。Ｓ１５は実施形態１のＳ４と対応している。 When it is raining in the store (Y in S12), the identification information output from the acoustic signal output device 1 is changed, and the database unit 53 is operated to display the rain information such as the identification information 0002 in FIG. It sets so that a daily coupon may be output (S13). If it is not raining in the store (N in S12), a normal coupon such as the identification information 0001 in FIG. 4B is distributed (S14). Then, the determined identification information is output from the acoustic signal output device 1 (S15). S15 corresponds to S4 of the first embodiment.
　さらに、タイムセールの時間か否かはコンピュータによって判断される（Ｓ１６）。図４（ｂ）のように、タイムセールの時間である１７時になると（Ｓ１６でＹ）、識別情報サーバ５の自動変更手段によって、携帯端末から送られた識別情報０００１・０００２に対してのタイムセール用クーポンを返送する（Ｓ１７）。 Further, it is determined by the computer whether it is time sale time (S16). As shown in FIG. 4B, when it is 17:00, which is the time sale time (Y in S16), the time for the identification information 0001 and 0002 sent from the portable terminal by the automatic change means of the identification information server 5 The sale coupon is returned (S17).
　実施形態２では、出力する識別情報の変更を自動と手動の２通りで行った。タイムセールなど前もって発生時間が決定可能な事象に対しては、従来の時刻による返送コンテンツの変更を行えばよい。しかし、天気など、発生時間が前もって決定できない事象に対しては、従来の時間による識別情報の変更では対応しきれていなかった。
　そのため、出力する識別信号の変更が可能な操作手段３を有することで、本実施形態のように突発的事象に対応した識別情報の手動変更が可能となる。実施店舗がチェーン店の場合、図３のように複数の音響信号出力装置を本部の操作手段１つで操作出来るようにしてもよい。 In the second embodiment, the identification information to be output is changed automatically and manually. For an event whose occurrence time can be determined in advance, such as a time sale, the return content may be changed according to the conventional time. However, events such as weather that cannot be determined in advance cannot be dealt with by changing the identification information according to the conventional time.
Therefore, by having the operation means 3 that can change the output identification signal, it is possible to manually change the identification information corresponding to the sudden event as in this embodiment. When the implementation store is a chain store, a plurality of acoustic signal output devices may be operated by one operation means at the headquarters as shown in FIG.
＜実施形態３＞
　図１、図２、及び図７を参照しながら本発明の実施形態３について説明する。なお、本実施形態において、上述した実施形態１及び実施形態２と基本的に同一の構成要素については、同一の符号を付してその説明を簡略化する。 <Embodiment 3>
A third embodiment of the present invention will be described with reference to FIGS. 1, 2, and 7. In the present embodiment, the same reference numerals are given to constituent elements that are basically the same as those in the first and second embodiments, and the description thereof will be simplified.
　本実施形態は、手動で識別情報の変更を行う例を示す。システムの全体構成は、実施形態１と同様である。 This embodiment shows an example in which identification information is manually changed. The overall system configuration is the same as that of the first embodiment.
　ライブ会場でのライブ音源と音響信号を、音響信号出力装置１を用いて重畳する。ライブ出演者の出演時間や、イベントの開場時間などは変動し易く、時刻による自動変更手段では返送コンテンツの提供タイミングにずれが生じる場合がある。そのため、出力する識別情報を手動で変更する必要がある。 The live sound source and sound signal at the live venue are superimposed using the sound signal output device 1. The appearance time of live performers, the opening time of events, etc. are likely to fluctuate, and there may be a difference in the provision timing of the return content in the automatic change means according to the time. Therefore, it is necessary to manually change the identification information to be output.
　まず、識別情報サーバ５にログインし（Ｓ２１）、データベースを設定して（Ｓ２２）出力する識別情報を決定する。識別情報の出力指示を行うことで、音響信号出力装置１の記憶部１５に選択した識別情報が記憶される（Ｓ２３）。そして、記憶部１５に保存された識別情報を、音響信号に変え、ライブ音源と重畳して出力する（Ｓ２４）。 First, login to the identification information server 5 (S21), set a database (S22), and determine the identification information to be output. By performing the output instruction of the identification information, the selected identification information is stored in the storage unit 15 of the acoustic signal output device 1 (S23). And the identification information preserve | saved at the memory | storage part 15 is changed into an acoustic signal, and it superimposes with a live sound source, and outputs it (S24).
　ライブの出演者変わったタイミングで、音響信号出力装置１の操作者は、出力する識別情報の変更指示を、操作手段３を用いて行う（Ｓ２５）。変更指示があった場合（Ｓ２５でＹ）、変更後の識別情報を音響信号出力装置１の記憶部１５に送信し、出力させる。出演者が入れ替わるごとに識別情報を変更することで、出演者と対応したコンテンツを利用者に対して配信することが可能となる。 At the timing when the live performer changes, the operator of the audio signal output device 1 gives an instruction to change the identification information to be output using the operation means 3 (S25). When there is a change instruction (Y in S25), the changed identification information is transmitted to the storage unit 15 of the acoustic signal output device 1 for output. By changing the identification information every time the performer is replaced, the content corresponding to the performer can be distributed to the user.
　実施形態３では、ライブなど時間の変動がある場合、識別情報の変更を手動で行う場合を説明した。これまでの時刻による変更方法では、データベース部の返送コンテンツを直接書き換えたり、コンテンツタイムテーブルの時間を逐次変更する他なかった。しかし本発明を利用することで、データベース部の書き換えといった複雑な作業をすることなく、識別情報の切り替え指示を出すだけで識別情報のライブ変更が可能となる。
　本実施形態では、出力する識別情報を音響信号出力装置の記憶部に保存し、出力させる手法をとったが、複数の識別情報を記憶し、テレビのリモコンのようなスイッチ等を用いて、識別情報サーバを通さずに変更できるようにしてもよい。 In the third embodiment, the case where the identification information is changed manually when there is a time variation such as live performance has been described. In the change method based on the time so far, there is no other way than directly rewriting the returned content in the database part or sequentially changing the time in the content time table. However, by using the present invention, it is possible to change the identification information live by simply issuing an instruction to switch the identification information without performing complicated operations such as rewriting the database section.
In this embodiment, the identification information to be output is stored in the storage unit of the acoustic signal output device and is output. However, a plurality of identification information is stored, and the identification information is identified by using a switch such as a television remote controller. You may enable it to change without going through an information server.
　本発明を利用することで、実店舗での集客コンテンツの配布、ライブ会場でのミュージシャン・曲の情報提供、といったように景観や雰囲気を壊すことなく、目に見えない形でコンテンツの配布を行うことが可能となる。 By using the present invention, contents can be distributed in an invisible form without destroying the scenery and atmosphere, such as distribution of contents for attracting customers at actual stores and provision of information on musicians and songs at live venues. It becomes possible.
