Abstract:
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.
