The control unit 102 performs various operations based on the received control information.
　また、第１再生装置１Ａは、通信Ｉ／Ｆ１０７を介して、第１子機１１Ａおよび第２子機１１Ｂにコンテンツデータを配信する。第１子機１１Ａおよび第２子機１１Ｂは、それぞれ第１再生装置１Ａから受信したコンテンツデータを再生する。第１再生装置１Ａは、第１子機１１Ａおよび第２子機１１Ｂにおけるコンテンツの出力タイミングに合わせて、自装置におけるコンテンツの出力タイミングを調整する。これにより、第１再生装置１Ａ、第１子機１１Ａ、および第２子機１１Ｂにおいて、１つのグループとして、同期再生を行なうことができる。第２再生装置１Ｂ、第３子機１２Ａ、第４子機１２Ｂ、および第５子機１２Ｃにおいても、同様の構成および機能により、１つのグループとして同期再生が行なわれる。 Further, the first playback device 1A distributes content data to the first slave unit 11A and the second slave unit 11B via the communication I / F 107. Each of the first slave unit 11A and the second slave unit 11B plays back the content data received from the first playback device 1A. The first playback device 1A adjusts the content output timing in the own device in accordance with the content output timing in the first slave device 11A and the second slave device 11B. Thereby, in 1st reproducing | regenerating apparatus 1A, 1st subunit | mobile_unit 11A, and 2nd subunit | mobile_unit 11B, synchronous reproduction | regeneration can be performed as one group. In the second playback device 1B, the third slave unit 12A, the fourth slave unit 12B, and the fifth slave unit 12C, synchronized playback is performed as one group with the same configuration and function.
　例えば、図１の例では、第１再生装置１Ａ、第１子機１１Ａ、および第２子機１１Ｂは、Ｒｏｏｍ１に設置されている。したがって、ユーザは、Ｒｏｏｍ１に設置された第１再生装置１Ａ、第１子機１１Ａ、および第２子機１１Ｂにおいて、同じコンテンツを聞くことができる。同様に、図１の例では、第２再生装置１Ｂ、第３子機１２Ａ、第４子機１２Ｂ、および第５子機１２Ｃは、Ｒｏｏｍ２に設置されている。したがって、ユーザは、Ｒｏｏｍ２に設置された第２再生装置１Ｂ、第３子機１２Ａ、第４子機１２Ｂ、および第５子機１２Ｃにおいて、同じコンテンツを聞くことができる。 For example, in the example of FIG. 1, the first playback device 1A, the first slave unit 11A, and the second slave unit 11B are installed in the Room 1. Therefore, the user can listen to the same content in the first playback device 1A, the first slave device 11A, and the second slave device 11B installed in the Room 1. Similarly, in the example of FIG. 1, the second playback device 1B, the third child device 12A, the fourth child device 12B, and the fifth child device 12C are installed in Room2. Therefore, the user can listen to the same content in the second playback device 1B, the third slave unit 12A, the fourth slave unit 12B, and the fifth slave unit 12C installed in the Room 2.
　次に、図３は、スマートフォン２の主要構成を示すブロック図である。スマートフォン２は、タッチパネル３０１、制御部３０２、ＲＯＭ３０３、ＲＡＭ３０４、表示部３０５、および通信Ｉ／Ｆ３０６を備えている。スマートフォン２は、情報処理装置の一例である。 Next, FIG. 3 is a block diagram showing the main configuration of the smartphone 2. The smartphone 2 includes a touch panel 301, a control unit 302, a ROM 303, a RAM 304, a display unit 305, and a communication I / F 306. The smartphone 2 is an example of an information processing device.

The display unit 305 presents various information to the user. The smartphone 2 implements GUI (Graphical User Interface) by the touch panel 301 and the display unit 305.
　制御部３０２は、記憶媒体であるＲＯＭ３０３に記憶されているＯＳおよびアプリケーションプログラムをＲＡＭ３０４に読み出すことで、各種の動作を行なう。図３に示す例では、制御部３０２は、移動情報受付部３９１、再生管理情報移動部３９２、および表示処理部３９３として機能する。表示処理部３９３は、ユーザからタッチパネル３０１を介してアプリケーションプログラムの起動が指示されると、指示されたアプリケーションプログラムを起動し、表示部３０５に該アプリケーションプログラムの画面を表示する。 The control unit 302 performs various operations by reading out the OS and application programs stored in the ROM 303, which is a storage medium, to the RAM 304. In the example illustrated in FIG. 3, the control unit 302 functions as a movement information reception unit 391, a reproduction management information movement unit 392, and a display processing unit 393. When the activation of the application program is instructed by the user via the touch panel 301, the display processing unit 393 activates the instructed application program and displays the screen of the application program on the display unit 305.
　図４（Ａ）は、アプリケーションプログラムの画面の一例を示す図である。図５は、スマートフォン２の動作を示すフローチャートである。図６は、装置間の情報の流れを示す図である。 FIG. 4A shows an example of the application program screen. FIG. 5 is a flowchart showing the operation of the smartphone 2. FIG. 6 is a diagram illustrating a flow of information between apparatuses.
　図４（Ａ）に示す画面では、第１再生装置１Ａ、第１子機１１Ａ、および第２子機１１Ｂにより形成される同期再生のグループとして、設置場所を示すＲｏｏｍ１というグループ名が表示されている。 On the screen shown in FIG. 4A, a group name “Room1” indicating the installation location is displayed as a group of synchronized playback formed by the first playback device 1A, the first slave device 11A, and the second slave device 11B. Yes.
　第１再生装置１Ａは、再生管理情報に基づいて、コンテンツの再生および配信を行なう。再生管理情報とは、図７（Ａ）に示すように、リスト情報、インデックス、再生位置、および設定情報を含む。リスト情報は、図７（Ｂ）に示すように、ユーザの選んだ任意のコンテンツリストの内容を示す情報である。インデックスは、リスト情報のうち、現在何番目のコンテンツを再生しているかを示す情報である。再生位置は、現在再生中のコンテンツの再生位置（再生開始からの経過時間）を示す情報である。設定情報は、リピート再生をするか否か、ランダム再生をするか否かを示す情報である。リピートは、現在再生中のコンテンツを繰り返し再生するか否か、またはリスト最後尾の再生後に最前列のコンテンツを再生するか否かを示す。ランダム再生は、リスト情報に列挙されたコンテンツをランダムに並べ替えた後の、再生順序を示す情報が含まれる。 The first playback device 1A plays back and distributes content based on playback management information. The reproduction management information includes list information, an index, a reproduction position, and setting information as shown in FIG. The list information is information indicating the contents of an arbitrary content list selected by the user, as shown in FIG. The index is information indicating what number content is currently being reproduced in the list information. The reproduction position is information indicating the reproduction position (elapsed time from the start of reproduction) of the content currently being reproduced. The setting information is information indicating whether or not repeat playback is performed and whether or not random playback is performed. Repeat indicates whether or not the content currently being reproduced is repeatedly reproduced, or whether or not the content in the front row is reproduced after reproduction at the end of the list. Random playback includes information indicating the playback order after the contents listed in the list information are randomly sorted.
　図４（Ａ）に示すように、現在、Ｒｏｏｍ１においては、曲名「Ｃｏｎｔｅｎｔｓ　Ａ」のオーディオデータが再生されている。すなわち、図７に示したリスト情報のうち、最前列のコンテンツである曲名「Ｃｏｎｔｅｎｔｓ　Ａ」が再生されている。 As shown in FIG. 4 (A), the audio data of the song title “Contents A” is currently being played in Room 1. That is, in the list information shown in FIG. 7, the song name “Contents A”, which is the content in the front row, is reproduced.
　ここで、ユーザは、Ｒｏｏｍ１からＲｏｏｍ２に移動して、Ｒｏｏｍ２においても現在再生しているコンテンツの続きを聞きたい場合がある。この場合、ユーザは、移動ボタン５０２を押す。これにより、図５に示すように、第１再生装置１Ａは、移動元の再生装置として受け付けられる（Ｓ１１）。表示処理部３９３は、移動ボタン５０２が押されると、図４（Ｂ）に示すようなＲｏｏｍ選択画面を表示する（Ｓ１２）。ユーザが、移動先のＲｏｏｍ（この例ではＲｏｏｍ２）を選択すると（Ｓ１３のＹｅｓ）、選択されたＲｏｏｍに対応する親機（ここでは第２再生装置１Ｂ）が移動先の再生装置として指定される。 Here, there is a case where the user moves from Room 1 to Room 2 and wants to hear the continuation of the content that is currently being played in Room 2. In this case, the user presses the movement button 502. As a result, as shown in FIG. 5, the first playback device 1A is accepted as the playback device of the movement source (S11). When the movement button 502 is pressed, the display processing unit 393 displays a room selection screen as shown in FIG. 4B (S12). When the user selects the destination Room (Room 2 in this example) (Yes in S13), the master unit (second playback device 1B in this case) corresponding to the selected Room is designated as the destination playback device. .
　移動情報受付部３９１は、以上のようにして、移動元の再生装置および移動先の再生装置を示す移動情報を受け付ける。図４（Ａ）および図４（Ｂ）の例では、第１再生装置１Ａが移動元の再生装置となり、第２再生装置１Ｂが移動先の再生装置となる。 The movement information reception unit 391 receives movement information indicating the movement source reproduction apparatus and the movement destination reproduction apparatus as described above. In the example of FIG. 4A and FIG. 4B, the first playback device 1A is the playback device that is the movement source, and the second playback device 1B is the playback device that is the movement destination.
　次に、再生管理情報移動部３９２は、移動情報に基づいて、移動元の第１再生装置１Ａにおけるコンテンツの再生管理情報を、移動先の第２再生装置１Ｂに移動させる処理を行なう。 Next, based on the movement information, the reproduction management information moving unit 392 performs a process of moving the content reproduction management information in the movement-source first reproduction device 1A to the movement-destination second reproduction device 1B.
　図５のフローチャートおよび図６のデータの流れでは、再生管理情報移動部３９２は、まず移動元の第１再生装置１Ａから再生管理情報を取得する（Ｓ１４）。そして、再生管理情報移動部３９２は、取得した再生管理情報を、移動先の第２再生装置１Ｂに送信する（Ｓ１５）。 In the flowchart of FIG. 5 and the data flow of FIG. 6, the reproduction management information moving unit 392 first obtains reproduction management information from the first reproduction apparatus 1A as the movement source (S14). Then, the reproduction management information moving unit 392 transmits the acquired reproduction management information to the second reproduction apparatus 1B that is the movement destination (S15).
　第２再生装置１Ｂは、スマートフォン２から送信された再生管理情報を取得し（Ｓ２１）、取得した再生管理情報に基づいて、コンテンツを再生する（Ｓ２２）。再生管理情報には、コンテンツが記憶されている装置を特定する情報（Ｓｏｕｒｃｅ）と、対象コンテンツを特定する情報（ＳｏｎｇＩＤ）と、が含まれる。 The second playback device 1B acquires the playback management information transmitted from the smartphone 2 (S21), and plays back the content based on the acquired playback management information (S22). The reproduction management information includes information (Source) for specifying a device in which the content is stored and information (SongID) for specifying the target content.
　Ｓｏｕｒｃｅは、例えば、機器の名称、ＩＰアドレス、または識別情報（メーカーＩＤまたはＭＡＣアドレス等）、等の装置を一意に特定するための識別情報と、コンテンツデータを入力するインタフェースを示す情報と、が含まれている。 The source includes, for example, identification information for uniquely identifying a device such as a device name, IP address, or identification information (such as a manufacturer ID or MAC address), and information indicating an interface for inputting content data. include.
　ＳｏｎｇＩＤは、対象コンテンツが一意に特定される識別情報であってもよいし、ディレクトリの選択位置を示す情報であってもよい。例えば、上述の曲名ＡＡＡのコンテンツがＵＳＢデバイスの最上層のディレクトリにおいて、２番目のデータとして保存されている場合には、選択位置を示す情報として、「１／２」という情報をＳｏｎｇＩＤとする。 The Song ID may be identification information for uniquely identifying the target content, or may be information indicating a directory selection position. For example, when the content of the above-mentioned song name AAA is stored as the second data in the uppermost directory of the USB device, information “1/2” is set as SongID as information indicating the selected position.
　なお、コンテンツの取得先は、配信システム内の装置であるとは限らない。例えば、外部サーバに保持されているコンテンツデータをダウンロード（またはストリーミング）する場合もある。この場合、図７のＳｏｎｇＩＤ００１０で示すコンテンツのように、再生管理情報としては、外部サーバのアドレス（ＵＲＬ）が示される。また、コンテンツのソースは、メディア等のアルバムである場合もある。この場合、再生管理情報は、Ｓｏｕｒｃｅと、アルバムのＩＤ、およびアルバム内のインデックスが含まれる。 Note that the content acquisition destination is not necessarily a device in the distribution system. For example, content data held in an external server may be downloaded (or streamed). In this case, like the content indicated by SongID0010 in FIG. 7, the reproduction management information indicates the address (URL) of the external server. The source of content may be an album such as media. In this case, the reproduction management information includes a source, an album ID, and an index within the album.
　以上のようにして、第２再生装置１Ｂにおいても、第１再生装置１Ａにおいて再生されていたコンテンツが再生される。その後、スマートフォン２は、移動元である第１再生装置１Ａに対して、再生の停止を指示する情報を送信する（Ｓ１６）。第１再生装置１Ａは、再生の停止を指示する情報を受信すると（Ｓ３１）、コンテンツの再生を停止する（Ｓ３２）。ただし、移動元の再生装置において再生を停止させることは必須ではない。 As described above, also in the second playback device 1B, the content played back in the first playback device 1A is played back. Thereafter, the smartphone 2 transmits information for instructing to stop the reproduction to the first reproduction apparatus 1A that is the movement source (S16). When the first playback device 1A receives information instructing to stop playback (S31), the first playback device 1A stops playback of the content (S32). However, it is not indispensable to stop the playback in the playback device of the movement source.
　これにより、図４（Ｃ）に示すように、移動先のＲｏｏｍ２においても、Ｒｏｏｍ１で聞いていたコンテンツが再生される。再生管理情報には、再生位置情報が含まれているため、Ｒｏｏｍ２においても、Ｒｏｏｍ１の再生位置から、続けてコンテンツが再生されることになる。ただし、再生位置情報は、必須ではない。移動先のＲｏｏｍ２においては、Ｒｏｏｍ１で再生していた曲名「Ｃｏｎｔｅｎｔｓ　Ａ」の先頭から再生を開始してもよい。 As a result, as shown in FIG. 4C, the content listened to in Room 1 is also reproduced in the destination Room 2. Since the reproduction management information includes reproduction position information, the content is continuously reproduced from the reproduction position of Room 1 even in Room 2. However, the reproduction position information is not essential. In the destination Room 2, playback may be started from the beginning of the song name “Contents A” that was played back in Room 1.
　このように、本実施形態の配信システムでは、ユーザが移動した先でもコンテンツの続きを再生させることができる。 Thus, in the distribution system of the present embodiment, the continuation of the content can be reproduced even when the user has moved.
　次に、図８は、変形例１に係る各装置の動作を示すフローチャートである。図５に示したフローチャートと同じ処理については同一の符号を付し、説明を省略する。変形例１では、スマートフォン２は、第１再生装置１Ａに対して、再生管理情報を第２再生装置１Ｂに送信するように指示を行なう（Ｓ１０４）。 Next, FIG. 8 is a flowchart showing the operation of each device according to the first modification. The same processes as those in the flowchart shown in FIG. In the first modification, the smartphone 2 instructs the first playback device 1A to transmit the playback management information to the second playback device 1B (S104).
　第１再生装置１Ａは、当該指示を受信すると（Ｓ２０１）、移動先である第２再生装置１Ｂに対して、再生管理情報を送信する（Ｓ２０２）。 When the first playback device 1A receives the instruction (S201), the first playback device 1A transmits playback management information to the second playback device 1B that is the movement destination (S202).
　第２再生装置１Ｂは、第１再生装置１Ａから再生管理情報を受信し（Ｓ２１）、受信した再生管理情報に基づいてコンテンツを再生する（Ｓ２２）。なお、第１再生装置１Ａは、Ｓ２０２の処理の後に、コンテンツの再生を停止してもよい。 The second playback device 1B receives the playback management information from the first playback device 1A (S21), and plays back the content based on the received playback management information (S22). Note that the first playback device 1A may stop playback of the content after the process of S202.
　図９は、変形例２に係る各装置の動作を示すフローチャートである。図５に示したフローチャートと同じ処理については同一の符号を付し、説明を省略する。変形例１では、スマートフォン２は、第２再生装置１Ｂに対して、再生管理情報を第１再生装置１Ａから取得するように指示を行なう（Ｓ１５４）。 FIG. 9 is a flowchart showing the operation of each device according to the second modification. The same processes as those in the flowchart shown in FIG. In the first modification, the smartphone 2 instructs the second playback device 1B to acquire the playback management information from the first playback device 1A (S154).
　第２再生装置１Ｂは、当該指示を受信すると（Ｓ３０１）、移動元である第１再生装置１Ａに対して再生管理情報を送信するよう要求する（Ｓ３０２）。第１再生装置１Ａは、当該要求を受信すると（Ｓ４０１）、第２再生装置１Ｂに対して、再生管理情報を送信する（Ｓ４０２）。なお、第１再生装置１Ａは、Ｓ４０１の処理の後に、コンテンツの再生を停止してもよい。 When the second playback device 1B receives the instruction (S301), the second playback device 1B requests the first playback device 1A that is the movement source to transmit playback management information (S302). When receiving the request (S401), the first playback device 1A transmits playback management information to the second playback device 1B (S402). Note that the first playback device 1A may stop playback of the content after the process of S401.
　第２再生装置１Ｂは、第１再生装置１Ａから再生管理情報を受信し（Ｓ２１）、受信した再生管理情報に基づいてコンテンツを再生する（Ｓ２２）。 The second playback device 1B receives the playback management information from the first playback device 1A (S21), and plays back the content based on the received playback management information (S22).
　次に、図１０は、変形例３に係るアプリケーション画面を示す図である。変形例３では、図１０（Ａ）に示すように、ユーザは、移動先であるＲｏｏｍ２の再生画面において、移動ボタン５０２を押す。これにより、第２再生装置１Ｂは、移動先の再生装置として受け付けられる。表示処理部３９３は、移動ボタン５０２が押されると、図１０（Ｂ）に示すようなＲｏｏｍ選択画面を表示する。ユーザが、移動元のＲｏｏｍ（この例ではＲｏｏｍ１）を選択すると、選択されたＲｏｏｍに対応する親機（ここでは第１再生装置１Ａ）が移動元の再生装置として指定される。 Next, FIG. 10 is a diagram showing an application screen according to the third modification. In the third modification, as shown in FIG. 10A, the user presses the movement button 502 on the reproduction screen of Room 2 as the movement destination. As a result, the second playback device 1B is accepted as a destination playback device. When the move button 502 is pressed, the display processing unit 393 displays a room selection screen as shown in FIG. When the user selects the source Room (Room 1 in this example), the master unit (here, the first playback device 1A) corresponding to the selected Room is designated as the source playback device.
　したがって、この場合も、図１０（Ｃ）に示すように、移動先のＲｏｏｍ２においても、Ｒｏｏｍ１で聞いていたコンテンツが再生される。 Therefore, also in this case, as shown in FIG. 10C, the content listened to in Room 1 is also reproduced in the destination Room 2.
　次に、図１１は、変形例４に係るアプリケーション画面を示す図である。変形例４では、移動先（または移動元）の選択画面において、再生管理情報の移行ができない場合に、エラー通知を行なう態様である。 Next, FIG. 11 is a diagram showing an application screen according to the fourth modification. In the fourth modification, an error notification is performed when reproduction management information cannot be transferred on the selection screen of the movement destination (or movement source).
　図１１（Ａ）に示すように、Ｒｏｏｍ１の再生画面において、移動ボタン５０２が押されると、表示処理部３９３は、図１１（Ｂ）に示すように、移動先の選択画面を表示する。ここで、例えばＲｏｏｍ３に設置された第３再生装置１Ｃにおいて、曲名「Ｃｏｎｔｅｎｔｓ　Ａ」のオーディオデータをデコードできず、当該コンテンツを再生できない場合、表示処理部３９３は、Ｒｏｏｍ３をグレー表示とする。また、例えば第３再生装置１Ｃが一時的に通信できない状態で、再生管理情報を受信できない状態である場合に、Ｒｏｏｍ３をグレー表示としてもよい。また、図１１（Ｃ）に示すように、再生管理情報を受信したものの、指定されたコンテンツを取得できず、コンテンツを再生できない場合に、「Ｓｏｕｒｃｅ　Ｅｒｒｏｒ」等と表示することで、エラー表示を行なってもよい。この例では、表示処理部３９３がエラー通知部として機能しているが、例えば音声によりエラー通知を行ってもよい。 As shown in FIG. 11A, when the move button 502 is pressed on the playback screen of Room 1, the display processing unit 393 displays a move destination selection screen as shown in FIG. 11B. Here, for example, in the third playback device 1C installed in Room 3, if the audio data of the song name “Contents A” cannot be decoded and the content cannot be played back, the display processing unit 393 displays Room 3 in gray. Further, for example, when the third playback device 1C is temporarily unable to communicate and cannot receive playback management information, Room 3 may be displayed in gray. Further, as shown in FIG. 11C, when the reproduction management information is received but the designated content cannot be acquired and the content cannot be reproduced, an error display is displayed by displaying “Source Error” or the like. You may do it. In this example, the display processing unit 393 functions as an error notification unit, but an error notification may be performed by voice, for example.
　次に、図１２は、変形例５として、再生装置間で主体的に再生管理情報を送受信する場合の構成を示す図である。変形例５では、配信システム９００は、スマートフォン２を備えていない。代わりに、各部屋には、物理ボタン１００が設置されている。物理ボタン１００は、再生装置に設けられていてもよいし、部屋の設備として設けられていてもよい。また、物理ボタン１００に変えて、第１再生装置１Ａに設けられた表示部（不図示）および操作部（不図示）を用いて、ユーザの操作を受け付けるようにしてもよい。 Next, FIG. 12 is a diagram showing a configuration in a case where reproduction management information is transmitted / received mainly between reproduction apparatuses as a fifth modification. In the modified example 5, the distribution system 900 does not include the smartphone 2. Instead, a physical button 100 is installed in each room. The physical button 100 may be provided in the playback device or may be provided as room equipment. Further, instead of the physical button 100, a user operation may be received using a display unit (not shown) and an operation unit (not shown) provided in the first playback device 1A.
　変形例５では、ユーザは、物理ボタン１００を用いて、移動元の再生装置および移動先の再生装置を指定する。例えばコンテンツを再生中に、物理ボタン１００が押された場合には、当該コンテンツを再生中の再生装置が移動元として指定される。コンテンツを再生していない状態で、物理ボタン１００が押された場合には、当該再生装置が移動先として指定される。あるいは、物理ボタン１００が長押しされた場合に移動元として指定され、物理ボタン１００が単押しされた場合に、移動先として指定される。また、「移動元ボタン」および「移動先ボタン」のように、複数のボタンを設ける態様も可能である。 In Modification 5, the user uses the physical button 100 to specify a playback device that is a movement source and a playback device that is a movement destination. For example, when the physical button 100 is pressed during reproduction of content, the reproduction device that is reproducing the content is designated as the movement source. When the physical button 100 is pressed while content is not being played back, the playback device is designated as the destination. Alternatively, it is designated as the movement source when the physical button 100 is pressed long, and is designated as the movement destination when the physical button 100 is single-pressed. Further, a mode in which a plurality of buttons are provided, such as “movement source button” and “movement destination button”, is also possible.
　移動先として指定された再生装置は、移動元として指定された再生装置を検索し、該移動元として指定された再生装置から再生管理情報を取得する。あるいは、移動元として指定された再生装置は、移動先として指定された再生装置を検索し、該移動先として指定された再生装置に対して再生管理情報を送信する。 The playback device specified as the movement destination searches for the playback device specified as the movement source, and acquires the playback management information from the playback device specified as the movement source. Alternatively, the reproduction device designated as the movement source searches for the reproduction device designated as the movement destination, and transmits reproduction management information to the reproduction device designated as the movement destination.
　例えばユーザが、Ｒｏｏｍ１を離れる前に、物理ボタンを押して第１再生装置１Ａを移動元として指定し、Ｒｏｏｍ３において物理ボタンを押すことで、第３再生装置１Ｃを移動先として指定する。すると、Ｒｏｏｍ１で再生されていたコンテンツがＲｏｏｍ３において再生される。したがって、ユーザはＲｏｏｍ１で聞いていたコンテンツの続きをＲｏｏｍ３において聞くことができる。 For example, before leaving the Room 1, the user presses the physical button to specify the first playback device 1A as the movement source, and presses the physical button in Room 3 to specify the third playback device 1C as the movement destination. Then, the content that was being played on Room 1 is played on Room 3. Therefore, the user can listen to the continuation of the content that has been listened to in Room 1 in Room 3.
　なお、ユーザの移動は、ユーザが所持する端末の位置を検出することでも検出可能である。端末の位置を検出する手法は、例えばＧＰＳを用いることも可能であるし、無線ＬＡＮまたはＢｌｕｅｔｏｏｔｈ（登録商標）等における電波強度を用いることでも可能である。例えば、各部屋にＢｌｕｅｔｏｏｔｈ　Ｌｏｗ　Ｅｎｅｒｇｙ規格（以下、ＢＬＥと称する。）に準じたビーコン信号を送受信する端末を設ける。そして、ユーザは、ビーコン信号を送受信するスマートフォン２を持ち歩く。スマートフォン２は、ビーコン信号を送信する。各部屋の端末は、スマートフォン２から受信したビーコン信号の受信電波強度に基づいて、ユーザ端末との距離を測定する。測定した距離は、各部屋の再生装置に送信される。再生装置は、受信した距離が、所定の値未満となった場合に、自装置を移動先の装置であるとして受け付ける。逆に、再生装置は、受信した距離が、所定の値以上となった場合に、自装置を移動元の装置であるとして受け付ける。 Note that the movement of the user can also be detected by detecting the position of the terminal owned by the user. As a method for detecting the position of the terminal, for example, GPS may be used, or radio wave intensity in a wireless LAN or Bluetooth (registered trademark) may be used. For example, a terminal that transmits and receives a beacon signal in accordance with the Bluetooth Low Energy standard (hereinafter referred to as BLE) is provided in each room. And a user carries the smart phone 2 which transmits / receives a beacon signal. The smartphone 2 transmits a beacon signal. The terminal in each room measures the distance from the user terminal based on the received radio wave intensity of the beacon signal received from the smartphone 2. The measured distance is transmitted to the playback device in each room. When the received distance is less than a predetermined value, the playback device accepts the device as a destination device. Conversely, when the received distance is equal to or greater than a predetermined value, the playback device accepts the own device as the source device.
　このようにして、ユーザの移動を検出し、検出したユーザの移動に応じて、移動元の再生装置および移動先の再生装置を示す移動情報を受け付ける態様も可能である。 In this way, it is also possible to detect the movement of the user and accept movement information indicating the movement source reproduction apparatus and the movement destination reproduction apparatus in accordance with the detected movement of the user.
　なお、上述の実施形態では、第１再生装置１Ａおよび第２再生装置１Ｂは、それぞれコンテンツの配信を行なう親機として機能する例を示したが、本発明において配信は必須ではない。 In the above-described embodiment, the first playback device 1A and the second playback device 1B each function as a master unit that distributes content. However, distribution is not essential in the present invention.
　上述の実施形態の説明は、すべての点で例示であって、制限的なものではないと考えられるべきである。本発明の範囲は、上述の実施形態ではなく、請求の範囲によって示される。更に、本発明の範囲には、請求の範囲と均等の意味及び範囲内での全ての変更が含まれることが意図される。 The description of the above-described embodiment is an example in all respects, and should be considered as not restrictive.
