(
DSD
Over
PCM) DoP is a method for transporting DSD audio over USB ports that do not have a DSD driver. Each consecutive set of 16 DSD bits is stored as PCM bits in the lower 16 bits of a 176.4/24 sampling rate. An 8-bit DoP header is added to each sample. In order to reassemble the PCM bits into a continuous DSD stream, the DAC at the playback end must be DoP compliant. See
