Abstract:
(EN) The present technique relates to a signal processing device, a signal processing method, and a program that allow one DSD signal to also support a PCM signal output. A distribution device comprises: an extraction unit for extracting, when generating a PCM signal with a prescribed sampling frequency from a DSD signal, a prescribed number of samples from the DSD signal, the prescribed number of samples mainly including samples with a prescribed interval determined by the prescribed sampling frequency; and a filtering unit for generating the PCM signal with the prescribed sampling frequency by filtering the prescribed number of samples extracted. The present technique can be applied to, for example, a distribution device that provides a client device with a PCM signal.
(FR) La présente invention concerne un dispositif de traitement de signal, un procédé de traitement de signal et un programme qui permettent à un signal DSD de prendre également en charge une sortie de signal PCM. Un dispositif de distribution comprend : une unité d'extraction pour extraire, lors de la génération d'un signal PCM à une fréquence d'échantillonnage prescrite à partir d'un signal DSD, un nombre prescrit d'échantillons du signal DSD, le nombre prescrit d'échantillons comprenant principalement des échantillons ayant un intervalle prescrit déterminé par la fréquence d'échantillonnage prescrite; et une unité de filtrage pour générer le signal PCM à la fréquence d'échantillonnage prescrite par filtrage du nombre prescrit d'échantillons extraits. La présente technique peut être appliquée, par exemple, à un dispositif de distribution qui fournit un signal PCM à un dispositif client.
(JA) 本技術は、1つのDSD信号で、PCM信号の出力も対応することができるようにする信号処理装置、信号処理方法、および、プログラムに関する。 配信装置は、DSD信号から所定のサンプリング周波数のPCM信号を生成する場合に、所定のサンプリング周波数によって決定される所定の間隔のサンプルを中心に、所定数のサンプルを、DSD信号から抽出する抽出部と、抽出された所定数のサンプルをフィルタリングすることにより、所定のサンプリング周波数のPCM信号を生成するフィルタリング部とを備える。本技術は、例えば、PCM信号をクライアント装置に配信する配信装置等に適用できる。
