Definition: DoP

(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 24/176.4 sampling rate. An 8-bit DoP header is added to each sample. At the playback end; however, the DAC must be DoP compliant in order to reassemble the PCM bits into a continuous DSD stream. See DSD.
