Description
配信部16は、コンテンツ受信部12が受信するPCM音源データを配信すると設定した場合(S2:コンテンツ受信部)、当該PCM音源データの先頭データをバッファ17に一時保持する(S21)。NAS170に記憶されているPCM音源データは、コンテンツ受信部12が必要に応じて受信するPULL型のデータである。換言すれば、NAS170に記憶されているPCM音源データは、バッファ可能でリアルタイム再生を要求しないものである。そこで、配信部16は、ステップS21では、所望の量のPCM音源データをバッファする。所望の量は、例えば、PCM音源データの2秒間の再生時間分に対応する。
プレーヤ150が出力するPCM音源データは、プレーヤ150が順次出力するPUSH型のデータである。換言すれば、プレーヤ150が出力するPCM音源データは、リアルタイム再生を必要とするものである。なお、本実施形態においてリアルタイム再生とは、外部入力部10に音声データが入力されたタイミングと、スピーカ200L、スピーカ200R、無線スピーカ301SL及び無線スピーカ301SRがその音声データを再生するタイミングと、が略同時であることを意味する。従って、本実施形態では、外部入力部10に音声データが入力されたタイミングと、各スピーカがその音声データを再生するタイミングとの間に数十ミリ秒の時間差がある再生もリアルタイム再生である。
