Description
本明細書に記載された実施形態は、再生デバイスに近接する障害物を検知することに基づいて、再生デバイス自体によって再生デバイスを動的に設定することを含む。実際には、再生デバイスは、家庭やビジネスなどの様々な場所の様々な位置に配置されている。多くの場合、他の物体が意図的に又は意図せずに再生デバイスの上又は周囲に配置される。例えば、額縁や植木鉢などの様々な家庭用品が再生デバイスの近くに配置される。状況によっては、特定の物体を再生デバイスの近くに配置することが単に便利である場合や、他の状況では、再生デバイスを隠すために特定の物体が使用される場合がある。その他の場合には、再生デバイスは壁の近くに置かれるか、あるいはキャビネットのような物体の内側に置かれる。いずれの場合でも、再生デバイスの周囲が再生デバイスの音声出力に対する障害物として作用する場合がある。
図1は、本明細書で開示されている1つ又は複数の実施形態で実施可能又は実装可能なメディア再生システム100の例示的な構成を示す。図示されるように、メディア再生システム100は、複数の部屋および空間、例えば、主寝室、オフィス、ダイニングルーム、およびリビングルームを有する例示的なホーム環境と関連付けられている。図1の例に示されるように、メディア再生システム100は、再生デバイス102−124、制御デバイス126および128、有線又は無線のネットワークルータ130を含む。
図2は、図1のメディア再生システム100の再生デバイス102−124の1つ又は複数を構成する例示的な再生デバイス200の機能ブロック図を示す。再生デバイス200は、プロセッサ202、ソフトウェアコンポーネント204、メモリ206、オーディオ処理コンポーネント208、オーディオアンプ210、スピーカー212、ネットワークインタフェース214および近傍センサ220を含んでもよい。ネットワークインタフェース214は、無線インタフェース216および有線インタフェース218を含む。ある場合では、再生デバイス200は、スピーカー212を含まないが、再生デバイス200を外部スピーカーに接続するためのスピーカーインタフェースを含んでいてもよい。別の場合では、再生デバイス200は、スピーカー212もオーディオアンプ210も含まないが、再生デバイス200を外部オーディオアンプ又はオーディオビジュアルレシーバーに接続するためのオーディオインタフェースを含んでもよい。
図1のメディア再生システムに戻って、環境は、1つ又は複数の再生ゾーンを有しており、それぞれの再生ゾーンは1つ又は複数の再生デバイスを含んでいる。メディア再生システム100は、1つ又は複数の再生ゾーンで形成されており、後で1つ又は複数のゾーンが追加又は削除して、図1に示す例示的な構成としてもよい。それぞれのゾーンは、異なる部屋又は空間、例えば、オフィス、浴室、主寝室、寝室、キッチン、ダイニングルーム、リビングルーム、および/又はバルコニーに基づく名前が与えられてもよい。ある場合では、単一の再生ゾーンは複数の部屋又は空間を含んでいてもよい。別の場合では、単一の部屋又は空間は、複数の再生ゾーンを含んでいてもよい。
図3は、メディア再生システム100の制御デバイス126と128とうちの一方又は両方を構成する例示的な制御デバイス300の機能ブロック図を示す。図示されるように、制御デバイス300は、プロセッサ302、メモリ304、ネットワークインタフェース306、およびユーザインタフェース308を含んでもよい。ある例では、制御デバイス300は、メディア再生システム100専用の制御デバイスであってもよい。別の例では、制御デバイス300は、メディア再生システムコントローラアプリケーションソフトウェアをインストールされたネットワークデバイス、例えば、iPhone(登録商標)、iPad(登録商標)、又は任意の他のスマートフォン、タブレットあるいはネットワークデバイス(例えば、PC又はMac(登録商標)などのネットワークコンピュータ)であってもよい。
前回図示したように、ゾーン又はゾーングループ内の1つ又は複数の再生デバイスは、再生するオーディオコンテンツを、(例えば、オーディオコンテンツの対応するURI又はURLに基づいて、)複数の入手可能なオーディオコンテンツソースから取り出すように構成されていてもよい。ある例では、オーディオコンテンツは、再生デバイスによって、対応するオーディオコンテンツソース(例えば、ライン−イン接続)から直接取り出されてもよい。別の例では、オーディオコンテンツは、1つ又は複数の他の再生デバイス若しくはネットワークデバイスを介してネットワーク上の再生デバイスに提供されてもよい。
上述したように、本明細書に述べられている実施形態は、再生デバイスに近接する障害物(barrier)を検知することに基づいて再生デバイスを動的に設定することを含む。
ブロック502において、再生デバイスは、再生デバイスに近接している障害物の表示を含む近傍データ(proximity data)を受信する。いくつかの実施形態では、近傍データは、再生デバイスの内部のセンサから受信される。他の実施形態では、近傍データは、再生デバイスに接続された1つ又は複数の外部センサから受信される。他の構成も可能である。
ブロック504において、再生デバイスは、再生デバイスに近接する障害物の表示に基づいて、障害物が再生デバイスの第1スピーカの閾値近傍範囲内(threshold proximity)にあることを検知する。
ブロック506において、再生デバイスの第1スピーカの閾値近傍範囲内にあるという検知に基づいて、再生デバイスは、当該再生デバイスの再生設定をセッティングする。再生設定のセッティングには、再生デバイスのスピーカを非アクティブ化することや、再生デバイスによって再生されるオーディオコンテンツのコンポーネントを調整することなどの様々なアクションが含まれる。
ブロック508において、再生デバイスは、再生設定に従ってオーディオコンテンツを再生する。例えば、再生デバイスの再生設定のセッティングにおいて再生デバイスの第1スピーカを非アクティブにすることが行われた場合、再生デバイスは、第1スピーカが停止している間にオーディオコンテンツを再生する。あるいは、別の例として、再生デバイスの再生設定のセッティングにおいてオーディオコンテンツのコンポーネントの調整が行われた場合、再生デバイスは、オーディオコンテンツのコンポーネントが調整された状態でオーディオコンテンツを再生する。
本明細書は、様々な例示のシステム、方法、装置、および製品などを開示しており、それらは、他のコンポーネントの中で、ハードウェア上で実行されるファームウェアおよび/又はソフトウェアを含む。そのような例は、単なる例示であり、限定されるものとみなすべきではないと理解される。例えば、これらのファームウェア、ハードウェア、および/又はソフトウェアの態様又はコンポーネントのいくつか又はすべてが、専らハードウェアに、専らソフトウェアに、専らファームウェアに、又はハードウェア、ソフトウェア、および/又はファームウェアの任意の組み合わせを実施することができることが意図されている。したがって、提供されているそれらの例は、それらのシステム、方法、装置、および/又は生産物を実施する唯一の方法ではない。
