　データベース４１０は、映像コンテンツの元となる映像データ、または、音コンテンツの元となる音データを記憶している。データベース４１０は、例えば、ストレージ４０３により実現される。 The database 410 stores video data that is a source of video content or sound data that is a source of sound content. The database 410 is realized by the storage 403, for example.
　取得部４２０は、入力受付部４３０に受け付けられた第２のユーザによる入力に応じて、データベース４１０から所定の音を示す音データを取得する。取得部４２０は、入力受付部４３０に受け付けられた第２のユーザによる入力に応じて、データベース４１０から映像データを取得してもよい。なお、取得部４２０は、音データまたは映像データを、データベース４１０から取得することに限らずに、通信部４５０を用いて、通信ネットワーク３００を介して他の情報処理装置から取得してもよいし、有線接続または無線接続された他の情報処理装置から直接取得してもよい。この場合の他の情報処理装置は、例えば、ＰＣ（Ｐｅｒｓｏｎａｌ　Ｃｏｍｐｕｔｅｒ）、サーバ、スマートフォン、タブレット端末、ビデオカメラ、デジタルカメラ、ＩＣレコーダなどである。取得部４２０は、例えば、ＣＰＵ４０１、メインメモリ４０２、およびストレージ４０３により実現される。 The acquisition unit 420 acquires sound data indicating a predetermined sound from the database 410 in response to the input by the second user received by the input reception unit 430. The acquisition unit 420 may acquire video data from the database 410 according to the input by the second user received by the input reception unit 430. Note that the acquisition unit 420 is not limited to acquiring sound data or video data from the database 410, but may be acquired from another information processing apparatus via the communication network 300 using the communication unit 450. Alternatively, it may be acquired directly from another information processing apparatus connected by wire or wireless. Other information processing apparatuses in this case are, for example, PCs (Personal Computers), servers, smartphones, tablet terminals, video cameras, digital cameras, IC recorders, and the like. The acquisition unit 420 is realized by the CPU 401, the main memory 402, and the storage 403, for example.
　入力受付部４３０は、第２のユーザによる入力を受け付ける。入力受付部４３０は、具体的には、第２のユーザがデータベース４１０に記憶されている映像データまたは音データからコンテンツを生成するための入力を受け付ける。入力受付部４３０は、コンテンツを生成するための入力として、コンテンツの制御情報の入力を受け付ける。 The input reception unit 430 receives an input by the second user. Specifically, the input receiving unit 430 receives an input for the second user to generate content from video data or sound data stored in the database 410. The input receiving unit 430 receives input of content control information as input for generating content.
　入力受付部４３０が受け付けるコンテンツの制御情報は、例えば、取得部４２０により取得された音データにより示される所定の音が、再生装置１００に設定されている設定音量を超えた音量で当該再生装置１００により出力されるのを禁止するために用いられ、所定の音の最大音量を示す最大音量情報を含む。 The content control information received by the input receiving unit 430 includes, for example, a predetermined sound indicated by the sound data acquired by the acquisition unit 420 at a volume that exceeds a set volume set in the playback apparatus 100. Is used for prohibiting the output of the sound, and includes maximum volume information indicating the maximum volume of a predetermined sound.
　入力受付部４３０が受け付けるコンテンツの制御情報は、例えば、音データの音量の調節を許可するか否かを示す属性情報をさらに含んでいてもよい。そして、この場合の制御情報は、当該制御情報が含む最大音量情報で示される最大音量が設定音量を超えている場合、以下の再生制御を再生装置１００に行わせる情報である。この場合の再生制御は、当該制御情報が含む属性情報が音量の調節を許可することを示す場合、当該制御情報と関連付けられた音データの所定の音の音量を設定音量以下に低下させた状態で、所定の音を出力させる第２の再生制御である。また、再生制御は、当該制御情報が含む属性情報が音量の調節を許可しないことを示す場合、当該制御情報と関連付けられた音データが再生装置１００により再生されることを禁止する第１の再生制御である。再生装置１００は、この制御情報に応じてコンテンツを再生した場合、属性情報が音量の調節を許可することを示す場合、第２の再生制御を行い、属性情報が音量の調節を許可しないことを示す場合、第１の再生制御を行う。このように、第２のユーザにより設定された属性情報に応じて、再生装置１００に第１の再生制御および第２の再生制御を選択的に切り替えて行わせることができる。 The content control information received by the input receiving unit 430 may further include, for example, attribute information indicating whether or not the adjustment of the volume of the sound data is permitted. The control information in this case is information that causes the playback device 100 to perform the following playback control when the maximum volume indicated by the maximum volume information included in the control information exceeds the set volume. In this case, in the reproduction control, when the attribute information included in the control information indicates that the volume adjustment is permitted, the volume of the predetermined sound of the sound data associated with the control information is reduced to a setting volume or less. This is the second reproduction control for outputting a predetermined sound. Further, in the reproduction control, when the attribute information included in the control information indicates that the adjustment of the volume is not permitted, the first reproduction that prohibits the reproduction apparatus 100 from reproducing the sound data associated with the control information. Control. When the reproduction apparatus 100 reproduces content according to this control information, if the attribute information indicates that the volume adjustment is permitted, the reproduction apparatus 100 performs the second reproduction control, and the attribute information does not permit the volume adjustment. When shown, the first reproduction control is performed. In this way, it is possible to cause the playback apparatus 100 to selectively switch between the first playback control and the second playback control according to the attribute information set by the second user.
　なお、第２の再生制御は、第３の再生制御および第４の再生制御を含んでいてもよい。つまり、第２の再生制御の代わりに第３の再生制御が行われてもよいし、第４の制御が行われてもよい。 Note that the second reproduction control may include third reproduction control and fourth reproduction control. That is, the third regeneration control may be performed instead of the second regeneration control, or the fourth control may be performed.
　また、入力受付部４３０が受け付けるコンテンツの制御情報は、（ｉ）音データの全体の音量の調節を許可する、（ｉｉ）音データの一部の音量の調節を許可する、および（ｉｉｉ）音データの音量の調節を許可しないのいずれかを示す属性情報をさらに含んでいてもよい。そして、この場合の制御情報は、当該制御情報が含む最大音量情報で示される最大音量が設定音量を超えている場合、以下の再生制御を再生装置１００に行わせる情報である。この場合の再生制御は、当該制御情報が含む属性情報が音データの全体の音量の調節を許可することを示す場合、当該制御情報と関連付けられた音データの所定の音の音量において、当該制御情報が含む平均音量情報で示される平均音量を、当該制御情報が含む最大音量情報で示される最大音量が設定音量以下となるまで低下させた状態で、所定の音を出力させる第３の再生制御である。また、再生制御は、当該制御情報が含む属性情報が音データの一部の音量の調節を許可する場合、当該制御情報と関連付けられた音データの所定の音における設定音量を超えている部分の音量を設定音量以下に低下させた状態で、所定の音を出力させる第４の再生制御である。また、再生制御は、当該制御情報が含む属性情報が音量の調節を許可しないことを示す場合、当該制御情報と関連付けられた音データが再生装置１００により再生されることを禁止する第１の再生制御である。 In addition, the content control information received by the input receiving unit 430 includes (i) allowing adjustment of the overall volume of the sound data, (ii) allowing adjustment of the volume of a part of the sound data, and (iii) sound. It may further include attribute information indicating that the adjustment of the volume of the data is not permitted. The control information in this case is information that causes the playback device 100 to perform the following playback control when the maximum volume indicated by the maximum volume information included in the control information exceeds the set volume. In this case, when the attribute information included in the control information indicates that the adjustment of the overall volume of the sound data is permitted, the reproduction control is performed at a predetermined sound volume of the sound data associated with the control information. Third reproduction control for outputting a predetermined sound in a state where the average volume indicated by the average volume information included in the information is reduced until the maximum volume indicated by the maximum volume information included in the control information is equal to or lower than the set volume. It is. In addition, in the reproduction control, when the attribute information included in the control information permits the adjustment of the volume of a part of the sound data, the reproduction control is performed on the part of the sound data associated with the control information that exceeds the set volume of the predetermined sound. This is the fourth reproduction control for outputting a predetermined sound in a state where the volume is lowered below the set volume. Further, in the reproduction control, when the attribute information included in the control information indicates that the adjustment of the volume is not permitted, the first reproduction that prohibits the reproduction apparatus 100 from reproducing the sound data associated with the control information. Control.
　入力受付部４３０が受け付けるコンテンツの制御情報は、例えば、当該制御情報が含む最大音量情報で示される最大音量が設定音量を超えている場合、当該制御情報と関連付けられた音データが再生装置１００により再生されることを禁止するための情報であってもよい。再生装置１００は、この制御情報に応じてコンテンツを再生した場合、最大音量が設定音量を超えているコンテンツの再生を行わない第１の再生制御を行う。このため、コンテンツに含まれる所定の音が、再生装置１００に設定されている設定音量を超えた音量で当該再生装置１００により出力されるのを抑制できる。 For example, when the maximum volume indicated by the maximum volume information included in the control information exceeds the set volume, the sound data associated with the control information is received by the playback device 100 when the content reception control information received by the input reception unit 430 exceeds the set volume. It may be information for prohibiting reproduction. When the content is reproduced according to the control information, the reproduction device 100 performs the first reproduction control not to reproduce the content whose maximum volume exceeds the set volume. For this reason, it can suppress that the predetermined | prescribed sound contained in a content is output by the said reproducing | regenerating apparatus 100 with the volume exceeding the setting volume set to the reproducing | regenerating apparatus 100. FIG.
　また、入力受付部４３０が受け付けるコンテンツの制御情報は、例えば、当該制御情報が含む最大音量情報で示される最大音量が設定音量を超えている場合、当該制御情報と関連付けられた音データの所定の音の音量を設定音量以下に低下させた状態で、所定の音を出力させる再生制御を再生装置１００に行わせるための情報であってもよい。再生装置１００は、この制御情報に応じてコンテンツを再生した場合、最大音量が設定音量を超えているコンテンツの音量を設定音量以下に低下させてコンテンツを再生する第２の再生制御を行う。このため、コンテンツに含まれる所定の音が、再生装置１００に設定されている設定音量を超えた音量で当該再生装置１００により出力されるのを抑制できる。 The content control information received by the input receiving unit 430 is, for example, a predetermined volume of sound data associated with the control information when the maximum volume indicated by the maximum volume information included in the control information exceeds the set volume. The information may be information for causing the playback device 100 to perform playback control for outputting a predetermined sound in a state where the volume of the sound is lowered below a set volume. When reproducing the content according to the control information, the reproducing device 100 performs second reproduction control for reproducing the content by reducing the volume of the content whose maximum volume exceeds the set volume to be equal to or lower than the set volume. For this reason, it can suppress that the predetermined | prescribed sound contained in a content is output by the said reproducing | regenerating apparatus 100 with the volume exceeding the setting volume set to the reproducing | regenerating apparatus 100. FIG.
　また、入力受付部４３０が受け付けるコンテンツの制御情報は、例えば、音データの所定の音の平均音量を示す平均音量情報をさらに含んでいてもよい。そして、この場合の制御情報は、当該制御情報が含む最大音量情報で示される最大音量が設定音量を超えている場合、当該制御情報と関連付けられた音データの所定の音の音量において、当該制御情報が含む平均音量情報で示される平均音量を最大音量が設定音量以下となるまで低下させた状態で、所定の音を出力させる再生制御を、再生装置１００に行わせるための情報であってもよい。再生装置１００は、この制御情報に応じてコンテンツを再生した場合、最大音量が設定音量以下となるまでコンテンツの平均音量を低下させてコンテンツを再生する第３の再生制御を行う。このため、コンテンツに含まれる所定の音が、再生装置１００に設定されている設定音量を超えた音量で当該再生装置１００により出力されるのを抑制できる。 Also, the content control information received by the input receiving unit 430 may further include, for example, average volume information indicating the average volume of a predetermined sound of the sound data. The control information in this case is the control information at a predetermined sound volume of the sound data associated with the control information when the maximum volume indicated by the maximum volume information included in the control information exceeds the set volume. Even if it is information for causing the playback apparatus 100 to perform playback control for outputting a predetermined sound in a state where the average volume indicated by the average volume information included in the information is reduced until the maximum volume is lower than or equal to the set volume. Good. When reproducing the content according to the control information, the reproducing device 100 performs third reproduction control for reproducing the content by reducing the average volume of the content until the maximum volume becomes equal to or lower than the set volume. For this reason, it can suppress that the predetermined | prescribed sound contained in a content is output by the said reproducing | regenerating apparatus 100 with the volume exceeding the setting volume set to the reproducing | regenerating apparatus 100. FIG.
　また、入力受付部４３０が受け付けるコンテンツの制御情報は、例えば、当該制御情報が最大音量情報で示される最大音量が設定音量を超えている場合、当該制御情報と関連付けられた音データの所定の音における設定音量を超えている部分の音量を設定音量以下に低下させた状態で、所定の音を出力させる再生制御を、再生装置１００に行わせるための情報である。なお、この制御情報は、当該制御情報と関連付けられた音データの所定の音における設定音量を超えていない部分については、音量の調節を行わずにコンテンツを再生させるための情報である。再生装置１００は、この制御情報に応じてコンテンツを再生した場合、所定の音において、設定音量を超えている部分の音量を設定音量以下に低下させてコンテンツを再生する第４の再生制御を行う。このため、コンテンツに含まれる所定の音が、再生装置１００に設定されている設定音量を超えた音量で当該再生装置１００により出力されるのを抑制できる。 The content control information received by the input receiving unit 430 is, for example, a predetermined sound of sound data associated with the control information when the maximum volume indicated by the maximum volume information in the control information exceeds the set volume. This is information for causing the playback apparatus 100 to perform playback control for outputting a predetermined sound in a state where the volume of the portion exceeding the set volume in is reduced below the set volume. This control information is information for reproducing the content without adjusting the volume of a portion of the sound data associated with the control information that does not exceed the set volume of the predetermined sound. When the content is reproduced according to the control information, the reproduction device 100 performs fourth reproduction control for reproducing the content by reducing the volume of the portion of the predetermined sound that exceeds the set volume below the set volume. . For this reason, it can suppress that the predetermined | prescribed sound contained in a content is output by the said reproducing | regenerating apparatus 100 with the volume exceeding the setting volume set to the reproducing | regenerating apparatus 100. FIG.
　なお、コンテンツの制御情報は、上記で説明した情報の他に、例えば、コンテンツのメタデータ（つまり属性情報）を含んでいてもよい。メタデータは、１つのコンテンツに対して１セット存在するものであり、再生時間、作者、アンビエント度、映像アンビエント度、又は、音アンビエント度、コンテンツのジャンルの各情報を含む。アンビエント度、映像アンビエント度、および、音アンビエント度の詳細は後述する。 The content control information may include, for example, content metadata (that is, attribute information) in addition to the information described above. One set of metadata exists for one content, and includes information on reproduction time, author, ambient level, video ambient level, or sound ambient level, and content genre. Details of the ambient degree, the video ambient degree, and the sound ambient degree will be described later.
　再生時間は、当該コンテンツが再生される際の時間長を示す情報である。 The playback time is information indicating the length of time when the content is played back.

　このように、コンテンツのアンビエント度等は、メタデータによって設定され得る。 Thus, the ambient degree of content and the like can be set by metadata.
　メタデータは、予め定められたフォーマットで作成されている。指標は、メタデータのフォーマットに従ってメタデータを解析することにより得られる。指標は、コンテンツに紐付けられる指標であって、連続値により表現される指標である。指標の一例は、再生されているコンテンツに対してユーザが向ける注意の度合いを示す推定指標である。より具体的には、上記指標は、再生されているコンテンツに対してユーザが向ける注意の度合いが大きいほど、より小さな値を有する指標である指標、又は、再生されているコンテンツに対してユーザが向ける注意の度合いが大きいほど、より大きな値を有する指標を採用し得る。ここで、前者をアンビエント度（Ａｍｂｉｅｎｔ　ｌｅｖｅｌ）ともいい、後者をコンシャス度（Ｃｏｎｓｉｏｕｓ　ｌｅｖｅｌ）ともいう。ユーザが向ける注意の度合いが大きいほど、例えば、そのコンテンツの再生時間の最初から最後まで映像が表示されている画面を注視し続け、かつ、出力されている音を集中して視聴することがより適していると言える。 Metadata is created in a predetermined format. The index is obtained by analyzing the metadata according to the metadata format. The index is an index associated with the content, and is an index expressed by a continuous value. An example of the index is an estimated index that indicates the degree of attention the user is directed to the content being played back. More specifically, the index is an index that is an index having a smaller value as the degree of attention directed to the content being played by the user is greater, or the user is directed to the content being played. As the degree of attention directed is greater, an index having a larger value may be employed. Here, the former is also referred to as an ambient level and the latter is also referred to as a conscious level. As the degree of attention directed by the user increases, for example, it is more likely to continue watching the screen on which the video is displayed from the beginning to the end of the playback time of the content, and concentrate on viewing the output sound. It can be said that it is suitable.
　なお、指標として、再生されているコンテンツに含まれる映像の色彩に関する指標である明度、彩度若しくは色相などを含んでもよいし、再生されているコンテンツに含まれる音の指標である音量若しくは周波数分布などを含んでもよい。さらに、指標として、これらの複数の指標から所定の算出方法によって算出される指標を含んでいてもよい。 The index may include brightness, saturation, hue, or the like that is an index related to the color of the video included in the content being played back, or volume or frequency distribution that is an index of the sound included in the content being played back Etc. may be included. Further, the index may include an index calculated by a predetermined calculation method from the plurality of indexes.
　以降では、指標としてアンビエント度を用いて説明するが、コンシャス度、及び、その他の指標を用いても同様の説明が成立する。また、アンビエント度は、例えば０から１００までの連続値に表現される指標であるとする。アンビエント度が０である場合、ユーザが向けると推定される注意の度合いが最も大きいことを意味し、アンビエント度が１００である場合、ユーザが向けると推定される注意の度合いが最も小さいことを意味するとする。 Hereinafter, the explanation will be made using the ambient degree as an index, but the same explanation can be established by using the consciousness degree and other indices. The ambient degree is an index expressed as a continuous value from 0 to 100, for example. When the degree of ambient is 0, it means that the degree of attention estimated to be directed by the user is the largest, and when the degree of ambient is 100, the degree of attention estimated to be directed by the user is the smallest. Then.
　コンテンツに紐付けられるアンビエント度は、コンテンツの映像部分に紐付けられるアンビエント度である映像アンビエント度と、コンテンツの音部分に紐付けられるアンビエント度である音アンビエント度と、から算出され得る。なお、映像アンビエント度は、映像指標の一例である。音アンビエント度は、音指標の一例である。 The ambient degree associated with the content can be calculated from the video ambient degree that is the ambient degree associated with the video part of the content and the sound ambient degree that is the ambient degree associated with the sound part of the content. The video ambient degree is an example of a video index. The sound ambient degree is an example of a sound index.
　映像アンビエント度は、例えば、コンテンツの映像の明度、彩度若しくは色相、又は、シーンチェンジの態様に基づいて算出されてもよい。より具体的には、以下のように算出される。 The video ambient degree may be calculated based on, for example, the brightness, saturation or hue of the video of the content, or the scene change mode. More specifically, it is calculated as follows.
　・コンテンツの映像の明度が高いほど、より低いアンビエント度が算出される。 ・ The higher the brightness of the content video, the lower the ambient degree is calculated.
　・コンテンツの映像の彩度が高いほど、より低いアンビエント度が算出される。 ・ The higher the saturation of the content video, the lower the ambient degree is calculated.
　・コンテンツの映像の色彩に基づいて、赤、橙又は黄のような暖色の色が多いほど、より高いアンビエントが算出され、青又は紫のような寒色の色が多いほど、より低いアンビエント度が算出される。 Based on the color of the content video, the higher the warm color such as red, orange or yellow, the higher the ambient, the higher the cold color such as blue or purple, the lower the ambient Calculated.
　・映像のシーンチェンジが多いほど、より低いアンビエント度が算出される。 ・ The lower the degree of ambientity, the more scene changes in the video.
　・シーンチェンジの際の映像の切り替えの態様として、一のシーンからその次のシーンへの切り替えの際に、フェードアウト、フェードイン又はクロスフェードのように画像が徐々に切り変わることが多いほど、より高いアンビエント度が算出される。一のシーンからその次のシーンへの切り替えの際に、画像が急に切り替えられることが多いほど、より低いアンビエント度が算出される。 -As a mode of video switching at the time of a scene change, when switching from one scene to the next scene, the more the image gradually changes like fade out, fade in or cross fade, the more A high degree of ambient is calculated. When switching from one scene to the next, the more frequently the images are switched, the lower the degree of ambient is calculated.
　また、音アンビエント度は、例えば、コンテンツの音の音量、音の周波数分布、又は、音量の変化の態様に基づいて音アンビエント度が算出されてもよい。より具体的には、以下のように算出される。 In addition, the sound ambient degree may be calculated based on, for example, the volume of the sound of the content, the frequency distribution of the sound, or the change in volume. More specifically, it is calculated as follows.
　・コンテンツの音の音量が大きいほど、より低いアンビエント度が算出される。 ・ The lower the degree of ambient, the higher the volume of the content sound.
　・コンテンツの音の周波数分布について、高音域（例えば１ｋＨｚ～２０ｋＨｚ程度）又は低音域（例えば２０Ｈｚ～２００Ｈｚ程度）の音が多いほど、より高いアンビエント度が算出され、中音域（例えば２００Ｈｚ～１ｋＨｚ程度）が多いほど、より低いアンビエント度が算出される。 -Regarding the frequency distribution of the sound of the content, the higher the sound in the high sound range (for example, about 1 kHz to 20 kHz) or the low sound range (for example, about 20 Hz to 200 Hz), the higher the ambient degree is calculated, and the medium sound range (for example, about 200 Hz to 1 kHz) ), The lower the degree of ambient is calculated.
　・音量の変化が急峻であるほど、より低いアンビエント度が算出される。 ・ The steeper change in volume results in a lower ambient level.
　なお、映像アンビエント度と音アンビエント度とからコンテンツのアンビエント度を算出する方法は、任意の方法を採用し得るが、例えば、平均又は加重平均を用いることができる。例えば、加重平均の重みを０から１までの範囲とし、映像アンビエント度の重みをαとすると、コンテンツのアンビエント度は、下記（式１）のように表わされる。 Note that, as a method of calculating the content ambient degree from the video ambient degree and the sound ambient degree, any method can be adopted, but for example, an average or a weighted average can be used. For example, when the weighted average weight is in the range from 0 to 1 and the video ambient degree weight is α, the ambient degree of the content is expressed as (Equation 1) below.
　コンテンツのアンビエント度
　　＝α×（映像アンビエント度）＋（１－α）×（音アンビエント度）　　　（式１） Ambient degree of content = α x (Video ambient degree) + (1-α) x (Sound ambient degree) (Formula 1)
　ここで、映像アンビエント度と音アンビエントとの重み付けは、例えば、以下のように定められる。 Here, the weighting of the video ambient degree and the sound ambient is determined as follows, for example.
　（１）音アンビエント度の重みを大きくする場合
　一般に人が、再生装置１００等が提示する映像に対して意図的に注意を向けないようにするには、目を瞑る、又は、目若しくは身体の向きを変えること等をすればよく、比較的容易である。一方、人が、再生装置１００等が提示する音に対して意図的に注意を向けないようにするには、耳を塞ぐなどの方法があり得るが、あまり容易ではなく、また仮に耳を塞いだとしても完全にユーザが感ずる音をなくすことは難しい。従って、ユーザは、コンテンツの映像部分に関しては、映像アンビエント度に無関係に、意図的に注意を背けることができるが、コンテンツの音部分に関しては、注意の度合いが音アンビエント度に近いものにならざるを得ない。 (1) Increasing the weight of the sound ambient level Generally, in order to prevent a person from intentionally paying attention to the video presented by the playback device 100 or the like, the eyes are meditated or the eyes or body It is only relatively easy to change the direction. On the other hand, in order to prevent a person from paying attention to the sound presented by the playback device 100 or the like, there is a method of closing the ear, but it is not so easy, and the ear is temporarily blocked. Even so, it is difficult to completely eliminate the sound felt by the user. Therefore, the user can intentionally turn away the attention regarding the video portion of the content regardless of the degree of video ambient, but the degree of attention does not have to be close to the degree of sound ambient regarding the sound portion of the content. I do not get.
　そこで、音アンビエント度の重みを映像アンビエント度の重みより重くする、つまり、αを０．５より小さい値にすることが有効である。このようにすると、コンテンツに紐付けられるアンビエント度において、音に対して人が向ける注意の度合いの寄与を相対的に大きくすることで、コンテンツに紐付けられるアンビエント度の振る舞いを、ユーザが向ける注意の度合いについての感覚に近づけることができる。 Therefore, it is effective to make the weight of the sound ambient degree heavier than the weight of the video ambient degree, that is, to make α smaller than 0.5. In this way, in the degree of ambient that is linked to the content, by making the contribution of the degree of attention directed by the person relative to the sound relatively large, the attention that the user directs the behavior of the ambient degree that is linked to the content. It is possible to get close to the sense of the degree.
　（２）映像アンビエント度の重みを大きくする場合
　人間が、再生装置１００が提示する映像に対して注意を向けないようにするのは比較的容易であると述べたが、ディスプレイ１０５の寸法が大きいと、再生装置１００が提示する映像から注意を背けることが難しくなる。 (2) When increasing the weight of the video ambient degree It has been stated that it is relatively easy for humans not to pay attention to the video presented by the playback device 100, but the size of the display 105 is large. This makes it difficult to distract from the video presented by the playback device 100.
　そこで、コンテンツが表示されると想定されるディスプレイ１０５の寸法が大きいほど、映像アンビエント度の重みを大きくすることが有効である。例えば、コンテンツが表示されると想定されるディスプレイ１０５の寸法に閾値を設け、その閾値を超える寸法のディスプレイ１０５によってコンテンツが表示されると想定される場合には、映像アンビエント度の重みを、音アンビエント度の重みより重くする、つまり、αが０．５より大きくすることが有効である。この閾値は、例えば、ディスプレイ１０５の対角線の長さで５０インチ、又は、７０インチ程度とすることができる。 Therefore, it is effective to increase the weight of the video ambient degree as the size of the display 105 on which the content is assumed to be displayed is larger. For example, when a threshold value is set for the dimension of the display 105 that is assumed to display the content, and the content is assumed to be displayed by the display 105 having a dimension that exceeds the threshold, the weight of the video ambient degree is set to sound. It is effective to make it heavier than the weight of the ambient degree, that is, to make α larger than 0.5. This threshold value can be about 50 inches or 70 inches in the length of the diagonal line of the display 105, for example.
　このようにすると、コンテンツに紐付けられる指標において、映像に対して人が向ける注意の度合いの寄与を相対的に大きくすることで、コンテンツに紐付けられるアンビエント度の振る舞いを、ユーザが向ける注意の度合いについての感覚に近づけることができる。 In this way, in the index associated with the content, the contribution of the degree of attention directed by the person to the video is relatively increased, so that the behavior of the ambient degree associated with the content is noticed by the user. You can get close to a sense of degree.
　なお、αは、再生システム１の運用者、コンテンツの提供者、又は、ユーザによる入力により変動できるようにしてもよい。このようにすることで、再生システム１の運用者等が柔軟に映像アンビエント度と音アンビエント度との重みを変化させることができる。その結果、ユーザの感覚に適合した、より柔軟なコンテンツの指定が可能となる利点がある。 Note that α may be changed by an input from the operator of the playback system 1, the provider of the content, or the user. In this way, the operator of the playback system 1 can flexibly change the weight of the video ambient level and the sound ambient level. As a result, there is an advantage that it is possible to specify more flexible content suitable for the user's sense.
　映像アンビエント度および音アンビエント度は、アンビエント度の大きさに応じて複数段階のランクに分類されていてもよい。この場合、映像アンビエント度の複数のランクを規定するアンビエント度の複数の範囲と、音アンビエント度の複数のランクを規定するアンビエント度の複数の範囲とは、互いに一致していなくてもよい。例えば、映像アンビエント度が０～２０の範囲でランクＡと分類され、音アンビエント度が０～３０の範囲でランクＡと分類されてもよい。つまり、映像アンビエント度と、音アンビエント度とは、同じランクであっても、異なるアンビエント度の範囲で複数のランクに分類されていてもよい。 The video ambient level and the sound ambient level may be classified into a plurality of ranks according to the magnitude of the ambient level. In this case, the plurality of ranges of ambient degrees that define the plurality of ranks of the video ambient degree and the plurality of ranges of ambient degrees that define the plurality of ranks of the sound ambient degree do not have to coincide with each other. For example, the video ambient degree may be classified as rank A in the range of 0 to 20, and the sound ambient degree may be classified as rank A in the range of 0 to 30. That is, the video ambient degree and the sound ambient degree may be classified into a plurality of ranks within the same rank or different ambient degree ranges.
　また、映像アンビエント度と音アンビエント度とは、最小値と最大値とが一致するように正規化されていてもよい。 Also, the video ambient degree and the sound ambient degree may be normalized so that the minimum value and the maximum value coincide.
　なお、コンテンツにはさまざまなコンテンツが有り得るが、ユーザによってあまり注視されることがない、壁に飾られた絵画、又は、壁紙、床若しくは天井の一部のように、環境の一部を形成するコンテンツであってもよい。なお、コンテンツは、ニュース又は教養等に関する情報を取得したり、娯楽を得たりするために注視することが想定されるコンテンツであってもよい。 There can be a variety of content, but it is part of the environment, such as paintings on the wall or parts of wallpaper, floor or ceiling that are not often watched by users It may be content. Note that the content may be content that is assumed to be watched in order to acquire information on news or culture or to obtain entertainment.
　次に、図６を用いて、入力受付部４３０により入力を受け付けるためのＵＩについて説明する。 Next, a UI for receiving input by the input receiving unit 430 will be described with reference to FIG.
　図６は、実施の形態における生成装置のディスプレイに表示されるＵＩの一例を示す図である。 FIG. 6 is a diagram illustrating an example of a UI displayed on the display of the generation apparatus according to the embodiment.
　入力受付部４３０は、ディスプレイ４０６にＵＩ４３１を表示して、入力ＩＦ４０５によるＵＩ４３１への入力を受け付ける。ＵＩ４３１は、音データのファイルの選択を受け付けるためのＵＩ４３２、最大音量の設定を受け付けるためのＵＩ４３３、平均音量の設定を受け付けるためのＵＩ４３４、音量の調節を許可するか否かを示す情報の入力を受け付けるためのＵＩ４３５、作者を示す文字列の入力を受け付けるためのＵＩ４３６を含む。なお、入力受付部４３０は、ＵＩ４３２～ＵＩ４３６の全てをディスプレイ４０６に表示させなくてもよく、少なくともＵＩ４３２およびＵＩ４３３を表示することで、音データのファイルを示す情報と、最大音量を示す最大音量情報との入力を受け付ければよい。また、入力受付部４３０は、ＵＩを表示させずに音データのファイルを示す情報と、最大音量を示す最大音量情報との入力を受け付けてもよい。 The input reception unit 430 displays the UI 431 on the display 406 and receives an input to the UI 431 by the input IF 405. The UI 431 receives a UI 432 for receiving a selection of a sound data file, a UI 433 for receiving a maximum volume setting, a UI 434 for receiving an average volume setting, and input of information indicating whether or not volume adjustment is permitted. It includes a UI 435 for accepting and a UI 436 for accepting input of a character string indicating the author. Note that the input reception unit 430 does not have to display all of the UIs 432 to 436 on the display 406. By displaying at least the UI 432 and the UI 433, information indicating the sound data file and maximum volume information indicating the maximum volume are displayed. Can be accepted. Further, the input receiving unit 430 may receive input of information indicating a sound data file and maximum volume information indicating the maximum volume without displaying a UI.
　ＵＩ４３２では、第２のユーザは、参照ボタンを押すことで、例えば生成装置４００のストレージ４０３に記憶されている音データのファイルを選択することができる。なお、図６で示すファイルは、一例であり、ｆｌａｃファイルに限らずに、ａａｃファイル、ｗａｖファイル、ｍｐ３ファイルなどの他の音声ファイルであってもよい。 In the UI 432, the second user can select a sound data file stored in the storage 403 of the generation apparatus 400, for example, by pressing a reference button. The file shown in FIG. 6 is an example, and is not limited to a flac file, but may be another audio file such as an aac file, a wav file, or an mp3 file.
　ＵＩ４３３では、スライダーのつまみを左右に移動させることで最大音量の設定を行うことができる。なお、ＵＩ４３３の代わりに、最大音量を示す数値の入力を受け付けてもよい。 In UI433, the maximum volume can be set by moving the slider knob to the left or right. Instead of the UI 433, an input of a numerical value indicating the maximum volume may be accepted.
　ＵＩ４３４では、スライダーのつまみを左右に移動させることで平均音量の設定を行うことができる。なお、ＵＩ４３４の代わりに、平均音量を示す数値の入力を受け付けてもよい。 In UI434, the average volume can be set by moving the slider knob to the left or right. Instead of the UI 434, an input of a numerical value indicating the average sound volume may be accepted.
　ＵＩ４３５では、ラジオボタン（オプションボタン）を選択することで、音量調節の許可または不許可を設定することができる。なお、ＵＩ４３５では、音量調節の許可または不許可を設定するＵＩであるが、（ｉ）音データの全体の音量を許可する、（ｉｉ）音データの一部の音量を許可する、および、（ｉｉｉ）音量の調節を許可しない、のうちの１つを設定するＵＩとしてもよい。 In UI435, by selecting a radio button (option button), permission or non-permission of volume adjustment can be set. Note that the UI 435 is a UI for setting permission or disapproval of volume adjustment, but (i) allows the entire volume of the sound data, (ii) allows a part of the sound data, and ( iii) It is good also as UI which sets one of not permitting volume adjustment.
　ＵＩ４３６では、テキストボックスに入力された文字列を作者として受け付けることができる。なお、生成装置４００に予め設定されているユーザ名が作者として自動的に入力されていてもよい。 The UI 436 can accept a character string input in a text box as an author. Note that a user name set in advance in the generation device 400 may be automatically input as the author.
　なお、入力受付部４３０は、例えば、入力ＩＦ４０５およびディスプレイ４０６により実現される。 Note that the input receiving unit 430 is realized by the input IF 405 and the display 406, for example.
　生成部４４０は、取得部４２０により取得された音データと、入力を受け付けた制御情報とを関連付けることによりコンテンツを生成する。生成部４４０は、例えば、図６に示したＵＩ４３１への入力を受け付けることで、図７に示すようなコンテンツＣ１０を生成する。つまり、生成部４４０は、ＵＩ４３２で選択された音データＣ１１と、ＵＩ４３３～ＵＩ４３６で受け付けられた制御情報Ｃ１２とを関連付けることでコンテンツＣ１０を生成する。なお、再生時間は、例えば、音データＣ１１を解析するまたは音データＣ１１に予め含まれる再生時間を示す情報から得られる。また、アンビエント度は、例えば、上述した方法により音データＣ１１を解析することにより算出される。生成部４４０は、例えば、ＣＰＵ４０１、メインメモリ４０２、およびストレージ４０３により実現される。 The generating unit 440 generates content by associating the sound data acquired by the acquiring unit 420 with the control information that has received the input. The generation unit 440 generates content C10 as illustrated in FIG. 7 by receiving an input to the UI 431 illustrated in FIG. 6, for example. That is, the generation unit 440 generates the content C10 by associating the sound data C11 selected by the UI 432 with the control information C12 received by the UI 433 to UI 436. Note that the reproduction time is obtained from, for example, information indicating the reproduction time included in the sound data C11 by analyzing the sound data C11. The ambient degree is calculated by analyzing the sound data C11 by the method described above, for example. The generation unit 440 is realized by, for example, the CPU 401, the main memory 402, and the storage 403.
　通信部４５０は、生成部４４０により生成されたコンテンツを、通信ネットワーク３００を介してサーバ２００に送信する。なお、通信部４５０は、当該コンテンツを、通信ネットワーク３００を介して再生装置１００に送信してもよい。通信部４５０は、例えば、ＣＰＵ４０１、メインメモリ４０２、ストレージ４０３、および通信ＩＦ４０４により実現される。 The communication unit 450 transmits the content generated by the generation unit 440 to the server 200 via the communication network 300. Note that the communication unit 450 may transmit the content to the playback device 100 via the communication network 300. The communication unit 450 is realized by, for example, the CPU 401, the main memory 402, the storage 403, and the communication IF 404.
　再生装置１００の機能構成について説明する。 The functional configuration of the playback device 100 will be described.
　再生装置１００は、通信部１１０と、再生部１３０とを備える。再生装置１００は、さらに、コンテンツＤＢ（Ｄａｔａｂａｓｅ）１２０を備えていてもよい。 The playback apparatus 100 includes a communication unit 110 and a playback unit 130. The playback device 100 may further include a content DB (Database) 120.
　通信部１１０は、通信ネットワーク３００を介してサーバ２００から、コンテンツを取得する。コンテンツは、例えば、所定の音を示す音データを含むコンテンツであり、映像コンテンツまたは音コンテンツである。つまり、コンテンツは、再生装置１００により再生されたときに、再生装置１００のスピーカ１０６から音が出力されるコンテンツである。通信部１１０は、サーバ２００から１つのコンテンツを取得してもよいし、複数のコンテンツを取得してもよい。通信部１１０は、例えば、ＣＰＵ１０１、メインメモリ１０２、ストレージ１０３、および通信ＩＦ１０４により実現される。 The communication unit 110 acquires content from the server 200 via the communication network 300. The content is, for example, content including sound data indicating a predetermined sound, and is video content or sound content. That is, the content is content in which sound is output from the speaker 106 of the playback device 100 when played back by the playback device 100. The communication unit 110 may acquire one content from the server 200 or may acquire a plurality of contents. The communication unit 110 is realized by the CPU 101, the main memory 102, the storage 103, and the communication IF 104, for example.
　コンテンツＤＢ１２０は、通信部１１０により取得されたコンテンツを記憶する。コンテンツＤＢ１２０は、例えば、ストレージ１０３により実現される。なお、コンテンツＤＢ１２０が記憶しているコンテンツは、通信部１１０により取得されたコンテンツに限らずに、予め記憶しているコンテンツであってもよいし、通信部１１０により取得されたコンテンツと、予め記憶しているコンテンツとが混在していてもよい。なお、コンテンツＤＢ１２０は、例えば、生成装置４００により生成されたコンテンツを工場出荷前に記憶することでコンテンツを予め記憶している。 The content DB 120 stores content acquired by the communication unit 110. The content DB 120 is realized by the storage 103, for example. Note that the content stored in the content DB 120 is not limited to the content acquired by the communication unit 110 but may be content stored in advance, or stored in advance with the content acquired by the communication unit 110. May be mixed with existing content. Note that the content DB 120 stores content in advance, for example, by storing content generated by the generation device 400 before factory shipment.
　再生部１３０は、通信部１１０により取得されたコンテンツを再生する。なお、再生部１３０は、通信部１１０により取得されたコンテンツを、ストリーミング再生してもよいし、コンテンツＤＢ１２０からコンテンツを読み出して再生してもよい。再生部１３０は、コンテンツに含まれる制御情報に応じて、当該コンテンツに含まれる音データを再生する。再生部１３０は、コンテンツに映像データが含まれる場合には、映像データと共に音データを再生してもよい。 The playback unit 130 plays back the content acquired by the communication unit 110. Note that the reproduction unit 130 may perform streaming reproduction of the content acquired by the communication unit 110, or may read and reproduce the content from the content DB 120. The reproduction unit 130 reproduces sound data included in the content according to control information included in the content. When the content includes video data, the playback unit 130 may play sound data together with the video data.
　再生部１３０は、例えば、通信部１１０により取得されたコンテンツに含まれる制御情報が含む最大音量情報を用いて、コンテンツに含まれる音データの所定の音を予め設定されている設定音量を超えた音量で出力しない再生制御を行う。なお、予め設定されている設定音量は、第１のユーザにより設定されていてもよいし、工場出荷時などに初期状態として設定されていてもよい。 The playback unit 130 uses, for example, the maximum volume information included in the control information included in the content acquired by the communication unit 110, and the predetermined sound of the sound data included in the content exceeds the preset volume. Playback control that does not output at volume is performed. Note that the preset volume may be set by the first user or may be set as an initial state at the time of factory shipment or the like.
　再生部１３０は、具体的には、当該制御情報が含む最大音量情報で示される最大音量が設定音量を超えている場合、当該制御情報と関連付けられた音データを再生しない第１の再生制御を行ってもよい。また、再生部１３０は、当該制御情報が含む最大音量情報で示される最大音量が設定音量を超えている場合、当該制御情報と関連付けられた音データの所定の音の音量を設定音量以下に低下させた状態で、所定の音を出力させる第２の再生制御を行ってもよい。また、再生部１３０は、当該制御情報が含む最大音量情報で示される最大音量が設定音量を超えている場合、当該制御情報と関連付けられた音データの所定の音の音量において、当該制御情報が含む平均音量情報で示される平均音量を最大音量が設定音量以下となるまで低下させた状態で、所定の音を出力させる第３の再生制御を行ってもよい。また、再生部１３０は、当該制御情報が最大音量情報で示される最大音量が設定音量を超えている場合、当該制御情報と関連付けられた音データの所定の音における設定音量を超えている部分の音量を設定音量以下に低下させた状態で、所定の音を出力させる第４の再生制御を行ってもよい。 Specifically, when the maximum volume indicated by the maximum volume information included in the control information exceeds the set volume, the reproduction unit 130 performs the first reproduction control that does not reproduce the sound data associated with the control information. You may go. Further, when the maximum volume indicated by the maximum volume information included in the control information exceeds the set volume, the playback unit 130 reduces the volume of the predetermined sound of the sound data associated with the control information to be equal to or lower than the set volume. In this state, the second reproduction control for outputting a predetermined sound may be performed. In addition, when the maximum volume indicated by the maximum volume information included in the control information exceeds the set volume, the playback unit 130 indicates that the control information is set at a predetermined sound volume of the sound data associated with the control information. The third reproduction control for outputting a predetermined sound may be performed in a state where the average volume indicated by the included average volume information is lowered until the maximum volume is equal to or lower than the set volume. In addition, when the maximum volume indicated by the maximum volume information in the control information exceeds the set volume, the playback unit 130 is a part of the sound data associated with the control information that exceeds the set volume in the predetermined sound. The fourth playback control for outputting a predetermined sound may be performed in a state where the volume is lowered to a set volume or less.
　また、再生部１３０は、当該制御情報が含む最大音量情報で示される最大音量が設定音量を超えている場合において、制御情報が音データの音量の調節を許可するか否かを示す属性情報を含む場合、属性情報に応じて第１の再生制御および第２の再生制御を選択的に行ってもよい。具体的には、再生部１３０は、当該制御情報が含む属性情報が音量の調節を許可することを示す場合、第２の再生制御を行い、当該制御情報が含む属性情報が音量の調節を許可しないことを示す場合、第１の再生制御を行ってもよい。 Further, the playback unit 130 includes attribute information indicating whether or not the control information permits adjustment of the volume of the sound data when the maximum volume indicated by the maximum volume information included in the control information exceeds the set volume. If included, the first reproduction control and the second reproduction control may be selectively performed according to the attribute information. Specifically, when the attribute information included in the control information indicates that the volume adjustment is permitted, the playback unit 130 performs the second playback control, and the attribute information included in the control information permits the volume adjustment. In the case of indicating not, the first reproduction control may be performed.
　また、再生部１３０は、当該制御情報が含む最大音量情報で示される最大音量が設定音量を超えている場合において、制御情報が（ｉ）音データの全体の音量の調節を許可する、（ｉｉ）音データの一部の音量の調節を許可する、および（ｉｉｉ）音データの音量の調節を許可しないのいずれかを示す属性情報を含む場合、属性情報に応じて、第１の再生制御、第３の再生制御および第４の再生制御を選択的に行ってもよい。具体的には、再生部１３０は、当該制御情報が含む属性情報が音データの全体の音量の調節を許可することを示す場合、第３の再生制御を行い、当該制御情報が含む属性情報が音データの一部の音量の調節を許可する場合、第４の再生制御を行い、当該制御情報が含む属性情報が音量の調節を許可しないことを示す場合、第１の再生制御を行う。 Further, when the maximum volume indicated by the maximum volume information included in the control information exceeds the set volume, the playback unit 130 allows the control information to (i) adjust the overall volume of the sound data. A first reproduction control according to the attribute information, when including attribute information indicating that the adjustment of the volume of a part of the sound data is permitted; and (iii) the adjustment of the volume of the sound data is not permitted. The third reproduction control and the fourth reproduction control may be selectively performed. Specifically, when the attribute information included in the control information indicates that the adjustment of the overall volume of the sound data is permitted, the playback unit 130 performs the third playback control, and the attribute information included in the control information When the adjustment of the volume of a part of the sound data is permitted, the fourth reproduction control is performed. When the attribute information included in the control information indicates that the adjustment of the volume is not permitted, the first reproduction control is performed.
　ここで、第３の再生制御および第４の再生制御について、図８～図１１を用いて説明する。 Here, the third reproduction control and the fourth reproduction control will be described with reference to FIGS.
　図８は、コンテンツの音量の再生時間における時間的変化を示す図である。図９は、コンテンツを再生装置で再生した場合に出力される再生音量の再生時間における時間的変化を示す図である。図１０は、第３の再生制御を行った場合に出力される再生音量の再生時間における時間的変化を示す図である。図１１は、第４の再生制御を行った場合に出力される再生音量の再生時間における時間的変化を示す図である。なお、図８～図１１で示されるコンテンツは一例であり、コンテンツの音量および再生音量は一例である。 FIG. 8 is a diagram showing a temporal change in the playback time of the volume of the content. FIG. 9 is a diagram showing a temporal change in the playback time of the playback volume output when the content is played back by the playback device. FIG. 10 is a diagram illustrating a temporal change in the reproduction time of the reproduction volume output when the third reproduction control is performed. FIG. 11 is a diagram illustrating a temporal change in the reproduction time of the reproduction volume output when the fourth reproduction control is performed. Note that the content shown in FIGS. 8 to 11 is an example, and the volume and playback volume of the content are examples.
　図８に示すように、コンテンツの音量は、時間ｔ１において最大音量ＶｏｌＭＡＸとなる。また、コンテンツの平均音量ＶｏｌＡＶＧは、図８の一点鎖線で示される。 As shown in FIG. 8, the volume of the content becomes the maximum volume Vol MAX at time t1. Further, the average volume Vol AVG of the content is indicated by a one-dot chain line in FIG.
　再生装置１００の再生部１３０は、図９に示すように、コンテンツの平均音量ＶｏｌＡＶＧが、第１のユーザによりリモコンなどを用いて調節されている音量である調整音量に一致させた音量でコンテンツに含まれる所定の音をスピーカ１０６から出力する再生制御を行う。この場合、再生部１３０は、コンテンツの音データにおいて音量の調節を行わないと、スピーカ１０６から出力される再生音量が設定音量よりも大きくなる場合がある。つまり、再生部１３０は、コンテンツの平均音量ＶｏｌＡＶＧが調節音量と一致するようにコンテンツを再生した場合、設定音量よりも大きい音量の音をスピーカ１０６から出力してしまう場合がある。 As shown in FIG. 9, the playback unit 130 of the playback apparatus 100 has a content with a volume in which the average volume Vol AVG of the content matches the adjusted volume, which is the volume adjusted by the first user using a remote controller or the like. Reproduction control for outputting a predetermined sound included in the sound from the speaker 106 is performed. In this case, if the playback unit 130 does not adjust the volume in the sound data of the content, the playback volume output from the speaker 106 may be larger than the set volume. In other words, when the content is played back so that the average volume Vol AVG of the content matches the adjusted volume, the playback unit 130 may output a sound having a volume higher than the set volume from the speaker 106.
　このため、再生部１３０は、例えば、図１０に示すように、第３の再生制御として、コンテンツの平均音量ＶｏｌＡＶＧを調節音量よりも低下させることで、出力される再生音量の最大音量が設定音量以下となるまで低下させる再生制御を行ってもよい。 Therefore, for example, as shown in FIG. 10, the playback unit 130 sets the maximum volume of the output playback volume by lowering the average volume Vol AVG of the content below the adjustment volume as the third playback control. You may perform the reproduction | regeneration control to which it decreases until it becomes below the volume.
　また、再生部１３０は、例えば、図１１に示すように、第４の再生制御として、コンテンツの再生音量が設定音量を超えている部分の音量を設定音量以下に低下させた状態で、所定の音を出力させる再生制御を行ってもよい。 Further, for example, as shown in FIG. 11, the playback unit 130 performs predetermined playback as the fourth playback control in a state in which the volume of the part where the playback volume of the content exceeds the set volume is reduced below the set volume. Playback control for outputting sound may be performed.
　再生部１３０は、例えば、ＣＰＵ１０１、メインメモリ１０２、ストレージ１０３、ディスプレイ１０５、およびスピーカ１０６により実現される。 The reproduction unit 130 is realized by, for example, the CPU 101, the main memory 102, the storage 103, the display 105, and the speaker 106.
　次に、サーバ２００の機能構成について説明する。 Next, the functional configuration of the server 200 will be described.
　サーバ２００は、データベース２１０と、比較部２２０と、生成部２３０と、通信部２４０とを備える。 The server 200 includes a database 210, a comparison unit 220, a generation unit 230, and a communication unit 240.
　データベース２１０は、映像コンテンツＤＢ（Ｄａｔａｂａｓｅ）２１１と、音コンテンツＤＢ（Ｄａｔａｂａｓｅ）２１２とを有する。映像コンテンツＤＢ２１１は、それぞれが独立した複数の映像コンテンツを記憶している。映像コンテンツＤＢ２１１は、複数の映像コンテンツと共に、複数の映像コンテンツのそれぞれに対応している制御情報を記憶している。音コンテンツＤＢ２１２は、それぞれが独立した複数の音コンテンツを記憶している。音コンテンツＤＢ２１２は、複数の音コンテンツと共に、複数の音コンテンツのそれぞれに対応している制御情報を記憶している。映像コンテンツＤＢ２１１は、通信部２４０により通信ネットワーク３００を介して生成装置４００から取得された映像コンテンツを記憶している。同様に、音コンテンツＤＢ２１２は、通信部２４０により通信ネットワーク３００を介して生成装置４００から取得された音コンテンツを記憶している。映像コンテンツＤＢ２１１および音コンテンツＤＢ２１２のそれぞれは、例えば、ストレージ２０３により実現される。 The database 210 includes a video content DB (Database) 211 and a sound content DB (Database) 212. The video content DB 211 stores a plurality of independent video contents. The video content DB 211 stores control information corresponding to each of the plurality of video contents together with the plurality of video contents. The sound content DB 212 stores a plurality of independent sound contents. The sound content DB 212 stores control information corresponding to each of the plurality of sound contents together with the plurality of sound contents. The video content DB 211 stores video content acquired from the generation apparatus 400 by the communication unit 240 via the communication network 300. Similarly, the sound content DB 212 stores sound content acquired from the generation device 400 by the communication unit 240 via the communication network 300. Each of the video content DB 211 and the sound content DB 212 is realized by the storage 203, for example.
　なお、サーバ２００は、データベース２１０記憶したコンテンツおよび制御情報の少なくとも一方を用いて、上記の方法を用いて、アンビエント度を算出してもよい。このようにアンビエント度が算出される場合、制御情報には、アンビエント度が含まれていなくてもよい。 Note that the server 200 may calculate the ambient degree using the above method using at least one of the content stored in the database 210 and the control information. When the degree of ambient is calculated in this way, the control information may not include the degree of ambient.
　比較部２２０は、複数の映像コンテンツのそれぞれに含まれる映像属性情報と、複数の音コンテンツのそれぞれに含まれる音属性情報とを比較する。比較部２２０は、例えば、映像コンテンツのジャンルと、音コンテンツのジャンルとが一致する場合、互いに類似すると判定する。なお、ジャンルには、コンテンツの作者、コンテンツが作成された日（または、月、年）が含まれていてもよい。比較部２２０は、例えば、映像アンビエント度と、音アンビエント度とが、所定の方法を用いて比較し、類似しているか否かを判定する。比較部２２０は、アンビエント度の大きさに応じて分類された複数のランクにおいて、映像コンテンツの映像アンビエント度が属するランクと、音コンテンツの音アンビエント度が属するランクとが同じである場合に、当該映像コンテンツおよび当該音コンテンツが互いに類似すると判定する。なお、比較部２２０は、映像属性情報に含まれるメタデータから映像アンビエント度を上記の方法を利用して算出し、音属性情報に含まれるメタデータから音アンビエント度を上記の方法を利用して算出してもよい。比較部２２０は、例えば、ＣＰＵ２０１、メインメモリ２０２、およびストレージ２０３により実現される。 The comparison unit 220 compares the video attribute information included in each of the plurality of video contents with the sound attribute information included in each of the plurality of sound contents. For example, when the genre of the video content matches the genre of the sound content, the comparison unit 220 determines that they are similar to each other. The genre may include the author of the content and the date (or month, year) when the content was created. For example, the comparison unit 220 compares the video ambient degree and the sound ambient degree using a predetermined method, and determines whether or not they are similar. When the rank to which the video ambient degree of the video content belongs and the rank to which the sound ambient degree of the sound content belong are the same among the plurality of ranks classified according to the magnitude of the ambient degree, the comparison unit 220 It is determined that the video content and the sound content are similar to each other. The comparison unit 220 calculates the video ambient degree from the metadata included in the video attribute information using the above method, and calculates the sound ambient degree from the metadata included in the sound attribute information using the above method. It may be calculated. The comparison unit 220 is realized by, for example, the CPU 201, the main memory 202, and the storage 203.
　生成部２３０は、比較部２２０による比較の結果に応じて、互いに類似する属性情報を有する映像コンテンツおよび音コンテンツで構成されるコンテンツを複数生成する。つまり、生成部２３０は、互いに類似する映像コンテンツおよび音コンテンツの組合せで構成されるコンテンツを複数生成する。生成部２３０は、例えば、ＣＰＵ２０１、メインメモリ２０２、およびストレージ２０３により実現される。 The generation unit 230 generates a plurality of contents composed of video content and sound content having attribute information similar to each other according to the comparison result by the comparison unit 220. That is, the generation unit 230 generates a plurality of contents composed of combinations of video content and sound content similar to each other. The generation unit 230 is realized by the CPU 201, the main memory 202, and the storage 203, for example.
　通信部２４０は、生成部２３０により生成された複数のコンテンツのうちの２以上のコンテンツを、通信ネットワーク３００を介して再生装置１００に送信する。通信部２４０は、再生装置１００からコンテンツの取得要求を受信した場合に、当該取得要求に応じたコンテンツを再生装置１００に送信してもよい。通信部２４０は、例えば、通信ＩＦ２０４により実現される。 The communication unit 240 transmits two or more contents among the plurality of contents generated by the generation unit 230 to the playback device 100 via the communication network 300. When the communication unit 240 receives a content acquisition request from the playback device 100, the communication unit 240 may transmit the content corresponding to the acquisition request to the playback device 100. The communication unit 240 is realized by the communication IF 204, for example.
　なお、サーバ２００は、比較部２２０および生成部２３０を必ずしも有していなくてもよい。つまり、サーバ２００は、生成装置４００から通信ネットワーク３００を介して映像コンテンツまたは音コンテンツを取得して、データベース２１０に記憶し、記憶した映像コンテンツまたは音コンテンツを、通信ネットワーク３００を介して再生装置１００に送信できる構成であればよい。 Note that the server 200 does not necessarily have the comparison unit 220 and the generation unit 230. That is, the server 200 acquires video content or sound content from the generation device 400 via the communication network 300, stores the video content or sound content in the database 210, and stores the stored video content or sound content via the communication network 300. Any configuration can be used as long as it can be transmitted to.
　［１－２．動作］
　次に、再生システム１の動作について説明する。 [1-2. Operation]
Next, the operation of the reproduction system 1 will be described.
　図１２は、実施の形態に係る生成装置による生成方法の一例を示すフローチャートである。 FIG. 12 is a flowchart illustrating an example of a generation method by the generation device according to the embodiment.
　取得部４２０が所定の音を示す音データを取得する（Ｓ１１）。 The acquisition unit 420 acquires sound data indicating a predetermined sound (S11).
　入力受付部４３０が制御情報の入力を受け付ける（Ｓ１２）。入力受付部４３０が受け付ける制御情報の詳細は、上述したとおりである。 The input receiving unit 430 receives input of control information (S12). The details of the control information received by the input receiving unit 430 are as described above.
　生成部４４０が取得部４２０により取得された音データと、入力受付部４３０により受け付けられた制御情報とを関連付けることによりコンテンツを生成する（Ｓ１３）。 The generating unit 440 generates content by associating the sound data acquired by the acquiring unit 420 with the control information received by the input receiving unit 430 (S13).
　通信部４５０が生成部４４０により生成されたコンテンツを、通信ネットワーク３００を介して、サーバ２００または再生装置１００に送信する（Ｓ１４）。 The communication unit 450 transmits the content generated by the generation unit 440 to the server 200 or the playback device 100 via the communication network 300 (S14).
　図１３は、実施の形態に係る再生装置による再生方法の一例を示すフローチャートである。 FIG. 13 is a flowchart showing an example of a reproduction method by the reproduction apparatus according to the embodiment.
　通信部１１０が通信ネットワーク３００を介してサーバ２００または生成装置４００からコンテンツを取得する（Ｓ２１）。 The communication unit 110 acquires content from the server 200 or the generation device 400 via the communication network 300 (S21).
　再生部１３０が通信部１１０により取得されたコンテンツを当該コンテンツに含まれる制御情報に応じて再生する（Ｓ２２）。再生部１３０により行われる再生処理の詳細は後述する。 The reproduction unit 130 reproduces the content acquired by the communication unit 110 according to the control information included in the content (S22). Details of the reproduction process performed by the reproduction unit 130 will be described later.
　図１４は、実施の形態に係る再生装置の再生部による再生処理の詳細の一例を示すフローチャートである。 FIG. 14 is a flowchart showing an example of the details of the reproduction processing by the reproduction unit of the reproduction apparatus according to the embodiment.
　再生部１３０は、通信部１１０により取得されたコンテンツに含まれる制御情報が含む最大音量情報で示される最大音量が設定音量を超えているか否かを判定する（Ｓ３１）。 The playback unit 130 determines whether or not the maximum volume indicated by the maximum volume information included in the control information included in the content acquired by the communication unit 110 exceeds the set volume (S31).
　再生部１３０は、最大音量が設定音量を超えていると判定した場合（Ｓ３１でＹｅｓ）、制御情報が含む属性情報が音データの音量の調節を許可することを示すか否かを判定する（Ｓ３２）。 When determining that the maximum volume exceeds the set volume (Yes in S31), the reproducing unit 130 determines whether or not the attribute information included in the control information indicates that the adjustment of the volume of the sound data is permitted ( S32).
　再生部１３０は、属性情報が音データの音量の調節を許可することを示す場合（Ｓ３２でＹｅｓ）、音データの最大音量を設定音量以下に低下させて再生する第２の再生制御を行う（Ｓ３３）。 When the attribute information indicates that the adjustment of the volume of the sound data is permitted (Yes in S32), the playback unit 130 performs the second playback control in which the maximum volume of the sound data is reduced below the set volume and played back ( S33).
　一方、再生部１３０は、属性情報が音データの音量の調節を許可しないことを示す場合（Ｓ３２でＮｏ）、当該コンテンツを再生しない第１の再生制御を行う（Ｓ３４）。 On the other hand, when the attribute information indicates that the adjustment of the volume of the sound data is not permitted (No in S32), the reproducing unit 130 performs the first reproduction control that does not reproduce the content (S34).
　再生部１３０は、最大音量が設定音量を超えていない場合（Ｓ３１でＮｏ）、コンテンツを音量の調節をせずにそのまま再生する（Ｓ３５）。 When the maximum volume does not exceed the set volume (No in S31), the playback unit 130 plays the content as it is without adjusting the volume (S35).
　なお、上記の再生処理において、ステップＳ３２およびＳ３４は行われなくてもよい。つまり、最大音量が設定音量を超えていると判定された場合、制御情報の属性情報の確認を行わずに、ステップＳ３３の第２の再生制御を行ってもよい。 In the above reproduction process, steps S32 and S34 may not be performed. That is, when it is determined that the maximum volume exceeds the set volume, the second reproduction control in step S33 may be performed without confirming the attribute information of the control information.
　上記の再生処理では、属性情報は、音データの音量の調節を許可するか否かを示す情報であるとしたが、上述したように、属性情報は、（ｉ）音データの全体の音量の調節を許可する、（ｉｉ）音データの一部の音量の調節を許可する、および（ｉｉｉ）音データの音量の調節を許可しないのいずれかを示す情報であってもよい。この場合の再生処理は、例えば、図１５に示す処理となる。 In the above reproduction processing, the attribute information is information indicating whether or not the adjustment of the volume of the sound data is permitted. However, as described above, the attribute information includes (i) the overall volume of the sound data. It may be information indicating any one of permitting adjustment, (ii) permitting adjustment of the volume of a part of the sound data, and (iii) not permitting adjustment of the volume of the sound data. The reproduction process in this case is, for example, the process shown in FIG.
　図１５は、実施の形態に係る再生装置の再生部による再生処理の詳細の他の一例を示すフローチャートである。 FIG. 15 is a flowchart illustrating another example of the details of the reproduction process performed by the reproduction unit of the reproduction apparatus according to the embodiment.
　なお、この再生処理では、図１４を用いて説明した再生処理においてステップＳ３３の代わりにステップＳ３６～Ｓ３８を行う点で異なる。このため、ステップＳ３６～Ｓ３８について説明する。 Note that this reproduction process is different in that steps S36 to S38 are performed instead of step S33 in the reproduction process described with reference to FIG. Therefore, steps S36 to S38 will be described.
　再生部１３０は、属性情報が音データの音量の調節を許可することを示す場合（Ｓ３２でＹｅｓ）、さらに、属性情報が音データの一部の音量調節のみを許可することを示すか、音データの全体の音量調節を許可することを示すかを判定する（Ｓ３６）。 When the attribute information indicates that the volume adjustment of the sound data is permitted (Yes in S32), the reproducing unit 130 further indicates that the attribute information only permits the volume adjustment of a part of the sound data, It is determined whether or not the volume adjustment of the entire data is permitted (S36).
　再生部１３０は、属性情報が音データの一部の音量調節のみを許可することを示す場合（Ｓ３６でＹｅｓ）、最大音量が設定音量を超えている部分の音量を調節して再生する第４の再生制御を行う（Ｓ３７）。 When the attribute information indicates that only the volume adjustment of part of the sound data is permitted (Yes in S36), the playback unit 130 adjusts the volume of the part where the maximum volume exceeds the set volume and plays back the fourth volume. The reproduction control is performed (S37).
　再生部１３０は、属性情報が音データの全体の音量調節を許可することを示す場合（Ｓ３６でＮｏ）、音データの平均音量を調節して音データの最大音量が設定音量以下となるまで低下して再生する第３の再生制御を行う（Ｓ３８）。 When the attribute information indicates that the volume control of the entire sound data is permitted (No in S36), the playback unit 130 adjusts the average volume of the sound data and decreases until the maximum volume of the sound data becomes equal to or lower than the set volume. Then, the third reproduction control for reproduction is performed (S38).
　［１－３．効果など］
　本実施の形態に係る生成方法によれば、コンテンツは、所定の音が、再生装置１００に設定されている設定音量を超えた音量で当該再生装置１００により出力されるのを禁止するために用いられる制御情報であって、所定の音の最大音量を示す最大音量情報を含む制御情報を含む。このため、再生装置１００が当該コンテンツを再生したときにコンテンツが設定音量を超えた音量で当該再生装置１００により出力されることを低減できる。よって、再生装置１００がコンテンツを再生したときに、再生装置１００がユーザに与える不快感を低減することができる。 [1-3. Effect etc.]
According to the generation method according to the present embodiment, the content is used to prohibit a predetermined sound from being output by the playback apparatus 100 at a volume that exceeds the set volume set in the playback apparatus 100. Control information including maximum volume information indicating the maximum volume of a predetermined sound. For this reason, when the reproducing apparatus 100 reproduces the content, it is possible to reduce the output of the content by the reproducing apparatus 100 at a volume exceeding the set volume. Therefore, when the playback device 100 plays back content, it is possible to reduce discomfort that the playback device 100 gives to the user.
　このように、例えば、生成方法では、アンビエント度が高いコンテンツを生成した場合であっても、上記のような制御情報を含んでいるため、再生装置１００により所定の音が出力される場合であっても、当該所定の音が設定音量を超えて出力されるのを低減できる。つまり、再生装置１００は、アンビエントなコンテンツとしてふさわしくない大きな音量でコンテンツの音が出力されるのを低減することができる。 Thus, for example, in the generation method, even when content with a high degree of ambient is generated, since the control information as described above is included, the playback device 100 outputs a predetermined sound. However, the output of the predetermined sound exceeding the set sound volume can be reduced. That is, the playback apparatus 100 can reduce the output of content sound at a large volume that is not suitable for ambient content.
　［１－４．変形例］
　［１－４－１．変形例１］
　上記実施の形態においてコンテンツは、制御情報に含まれる属性情報として、音データの音量の調節を許可するか否かを示す属性情報、または、（ｉ）音データの全体の音量の調節を許可する、（ｉｉ）音データの一部の音量の調節を許可する、および（ｉｉｉ）音データの音量の調節を許可しないのいずれかを示す属性情報を含むとしたが、これに限らない。上記の属性情報の代わりに、第１の再生制御を行わせることを示す属性情報、第２の再生制御を行わせることを示す属性情報、第３の再生制御を行わせることを示す属性情報、第４の再生制御を行わせることを示す属性情報のいずれか１つを含んでいてもよい。再生装置１００は、上記の属性情報を含むコンテンツを再生する場合、上記の属性情報が示す再生制御、つまり、第１の再生制御、第２の再生制御、第３の再生制御および第４の再生制御のいずれか１つを行う。 [1-4. Modified example]
[1-4-1. Modification 1]
In the above embodiment, the content is attribute information included in the control information, which is attribute information indicating whether or not to allow adjustment of the volume of the sound data, or (i) adjustment of the overall volume of the sound data is permitted. , (Ii) includes attribute information indicating that the adjustment of the volume of a part of the sound data is permitted and (iii) the adjustment of the volume of the sound data is not permitted. However, the present invention is not limited to this. In place of the attribute information, attribute information indicating that the first reproduction control is performed, attribute information indicating that the second reproduction control is performed, attribute information indicating that the third reproduction control is performed, Any one of the attribute information indicating that the fourth reproduction control is performed may be included. When reproducing the content including the attribute information, the reproduction device 100 reproduces the reproduction control indicated by the attribute information, that is, the first reproduction control, the second reproduction control, the third reproduction control, and the fourth reproduction. Perform any one of the controls.
　［１－４－２．変形例２］
　上記実施の形態における再生装置１００は、コンテンツを再生する場合、コンテンツとともに、アンビエント度に関する画像を表示してもよい。画像は、コンテンツのアンビエント度を示す画像、及び、図示しないリモコンなどの受付部により受け付けたアンビエント度の範囲を示す画像の少なくとも一方を含んでいてもよい。 [1-4-2. Modification 2]
When reproducing the content, the reproducing apparatus 100 in the above embodiment may display an image related to the ambient degree together with the content. The image may include at least one of an image indicating the ambient degree of the content and an image indicating the range of the ambient degree received by a receiving unit such as a remote controller (not shown).
　コンテンツとともにアンビエント度に関する画像をディスプレイ１０５に表示されることで、ユーザは、再生されているコンテンツとともに当該画像を視認する。ユーザは、アンビエント度を示す画像を視認すれば、現在再生されているコンテンツのアンビエント度を認識することができる。また、ユーザは、アンビエント度の範囲を示す画像を視認すれば、自身が指定しているアンビエント度の範囲を認識することができる。これらを認識することで、ユーザは、例えば、指定しているアンビエント度を現在より高く又は低く変更することを受付部を通じて再生装置１００に指示することができる。 By displaying an image related to the ambient degree together with the content on the display 105, the user visually recognizes the image together with the content being reproduced. The user can recognize the ambient level of the currently reproduced content by visually recognizing an image indicating the ambient level. Further, the user can recognize the range of the ambient degree designated by the user by visually recognizing the image indicating the range of the ambient degree. By recognizing these, for example, the user can instruct the playback device 100 to change the specified ambient degree higher or lower than the current degree through the reception unit.
　なお、アンビエント度に関する画像を提示することに代えて、又は、ともに、アンビエント度に関する音声をスピーカ１０６により出力してもよく、上記と同様の効果が得られる。 Note that, instead of presenting an image relating to the ambient degree, or together, a sound relating to the ambient degree may be output by the speaker 106, and the same effect as described above can be obtained.
　［１－５．その他の効果］
　また、本実施の形態及び本変形例に示される再生装置の制御方法によれば、再生装置は、コンテンツに紐付けられた指標を、その指標の範囲でもって指定することで、再生させるコンテンツを指定し得る。その際、ユーザは、検索キーを想起する必要はない。ユーザは、コンテンツに紐付けられた指標の大まかな値を、その範囲でもって指定するだけで、再生装置により再生させるコンテンツを指定し得る。このように、再生装置は、より柔軟なコンテンツの指定を可能とする。また、柔軟なコンテンツの指定を可能とするので、ユーザの意図を反映したコンテンツの決定に失敗した場合における再生装置の処理負荷及び消費電力の増大の問題を未然に回避し得る。 [1-5. Other effects]
Further, according to the control method of the playback device shown in the present embodiment and this modification, the playback device specifies the index associated with the content within the range of the index, and thereby the content to be played back Can be specified. At that time, the user need not recall the search key. The user can specify the content to be played back by the playback device simply by specifying the rough value of the index associated with the content within the range. In this way, the playback device enables more flexible content specification. Also, since flexible content specification is possible, the problem of increase in processing load and power consumption of the playback device when determination of content reflecting the user's intention fails can be avoided.
　また、再生装置は、再生されているコンテンツに対してユーザが向ける注意の度合いを示す推定指標を、具体的に指標として用いることによって、より柔軟なコンテンツの指定を可能とする。 Also, the playback device enables more flexible content specification by using, as a specific index, an estimated index that indicates the degree of attention that the user directs to the content being played back.
　また、再生装置、サーバまたは生成装置は、コンテンツに含まれる映像と音とのそれぞれに対してユーザが向ける注意の度合いに基づいて、コンテンツに紐付けられる指標を算出する。これにより、コンテンツに含まれる映像と音とを考慮してコンテンツの指標を算出することができる。 In addition, the playback device, the server, or the generation device calculates an index associated with the content based on the degree of attention directed by the user to each of the video and the sound included in the content. As a result, the content index can be calculated in consideration of the video and sound included in the content.
　また、再生装置、サーバまたは生成装置は、映像指標と音指標とのうちの音指標の重みを重くした加重平均により、コンテンツに紐付けられる指標を算出する。一般に人が、再生装置が提示する映像に対して意図的に注意を向けないようにすることは比較的容易であるが、音に対して意図的に注意を向けないようにするのは容易ではない。つまり、再生装置が提示する音から意図的に注意を背けることは難しいという特徴がある。そこで、コンテンツに紐付けられる指標において、音に対して人が向ける注意の度合いの寄与を相対的に大きくすることで、コンテンツの指定に用いる指標を、ユーザが向ける注意の度合いについての感覚に即した指標にすることができる。 Also, the playback device, server, or generation device calculates an index associated with the content by a weighted average obtained by increasing the weight of the sound index of the video index and the sound index. In general, it is relatively easy for a person not to pay attention to the video presented by the playback device, but it is not easy to intentionally not pay attention to the sound. Absent. In other words, it is difficult to intentionally turn away from the sound presented by the playback device. Therefore, in the index linked to the content, the contribution of the degree of attention directed by the person to the sound is relatively increased, so that the index used for specifying the content can be adapted to the sense of the degree of attention directed by the user. Index.
　また、再生装置、サーバまたは生成装置は、映像指標と音指標とのうちの映像指標の重みを重くした加重平均により、コンテンツに紐付けられる指標を算出する。一般に、コンテンツを表示する表示画面の寸法が大きいと、ユーザは、映像から注意を背けることが難しい。このような場合に、コンテンツに紐付けられる指標において、映像に対して人が向ける注意の度合いの寄与を相対的に大きくすることで、コンテンツの指定に用いる指標を、ユーザが向ける注意の度合いについての感覚に即した指標にすることができる。 Also, the playback device, server, or generation device calculates an index associated with the content by a weighted average obtained by increasing the weight of the video index among the video index and the sound index. In general, when the size of a display screen for displaying content is large, it is difficult for the user to distract from the video. In such a case, in the index associated with the content, the index of the index used for specifying the content is set with respect to the degree of the attention directed by the user by relatively increasing the contribution of the degree of attention directed by the person to the video. It can be an indicator that matches the sense of

　以上、本発明の一つまたは複数の態様に係る生成方法、生成装置、再生方法および再生システムについて、実施の形態に基づいて説明したが、本発明は、この実施の形態に限定されるものではない。本発明の趣旨を逸脱しない限り、当業者が思いつく各種変形を本実施の形態に施したものや、異なる実施の形態における構成要素を組み合わせて構築される形態も、本発明の一つまたは複数の態様の範囲内に含まれてもよい。 As described above, the generation method, the generation device, the reproduction method, and the reproduction system according to one or more aspects of the present invention have been described based on the embodiment. However, the present invention is not limited to this embodiment. Absent. Unless it deviates from the gist of the present invention, one or more of the present invention may be applied to various modifications that can be conceived by those skilled in the art, or forms constructed by combining components in different embodiments. It may be included within the scope of the embodiments.
　例えば、上記実施の形態では、音アンビエント度は、コンテンツの音の音量、音の周波数分布、又は、音量の変化の態様に基づいて算出する説明をした。しかし、これに限定されるものではなく、音の周波数特性の中でも、いわゆる『１／ｆゆらぎ』と呼ばれる特性との近似性や倍音成分の多寡、音色の波形の規則性（数Ｈｚ以下の周波数領域）などを考慮してもよい。 For example, in the above-described embodiment, the sound ambient degree is described based on the volume of the sound of the content, the frequency distribution of the sound, or the change of the volume. However, the present invention is not limited to this. Among the sound frequency characteristics, the approximation with the so-called “1 / f fluctuation” characteristic, the number of overtone components, the regularity of the timbre waveform (frequency of several Hz or less) Area) and the like.
　なお、音アンビエント度は、映像アンビエント度に比べ、研究段階の指標であるが、２００Ｈｚ付近の中音域の音は、ボーカルや人の話し声などに相当し、人間にとって耳につきやすい音域であることが分かっている。したがって、ユーザが向ける注意の度合いが大きくなり、コンシャス度が上がる（アンビエント度が下がる）と考えられる。 Note that the sound ambient level is an index at the research stage compared to the video ambient level, but the mid-range sound around 200 Hz is equivalent to vocals and human speech, and is likely to be heard by humans. I know it. Therefore, it is considered that the degree of attention directed by the user increases, and the degree of consciousness increases (the degree of ambient decreases).
　人間は自然界に存在する（人工的に加工されていない）広い帯域の音を聞きながら生活しているが、脳は、これらの広い帯域の音を常に無意識に処理している。人間の脳は、倍音構造の変化や微妙な遅れなどを手掛かりとして通常と異なる音を判別し、危険を察知するために注意の度合いが大きくなる。すなわち、コンシャス度が上がる（アンビエント度が下がる）と考えられる。 Human beings live while listening to sounds in a wide band that exist in nature (not artificially processed), but the brain always processes these wide band sounds unconsciously. The human brain discriminates unusual sounds using clues such as overtone structure changes and subtle delays, and the degree of attention increases in order to detect danger. That is, it is considered that the degree of consciousness increases (the degree of ambient decreases).
　また、人間の脳は、自然と異なるものを無意識に補完して理解しようとするため、自然界と異なる音を聞いたときには、脳のリソースを使ってしまうこととなり、コンシャス度が上がる（アンビエント度が下がる）と考えられる。したがって、ユーザの注意の度合いを大きくするために作曲された音楽が、コンシャス度が高い（アンビエント度が低い）だけではなく、川のせせらぎのような自然界に存在する音も、録音環境（マイクや記録装置の性能）によっては、アンビエント度が下がると考えられる。 In addition, the human brain tries to understand what is different from nature by unknowingly complementing it, so when listening to sounds that are different from the natural world, it will use brain resources, increasing the degree of consciousness (the degree of ambient is increased). It is thought that). Therefore, music that is composed to increase the degree of user's attention is not only highly conscious (low ambient), but also sounds that exist in the natural world, such as river buzz, can be recorded in a recording environment (such as a microphone or Depending on the performance of the recording device, the degree of ambient may be reduced.
　本開示は、再生装置がユーザに与える不快感を低減することができる生成方法等に適用可能である。 The present disclosure can be applied to a generation method that can reduce discomfort given to the user by the playback device.
