A higher sound quality and more efficient digital transmission system which is a combination of near-instantaneous companding PCM (NIPCM) and differential PCM (DPCM) was realized by means of accumulation of the removed bits during compression in NIPCM. This paper describes in detail that the dc shift due to erroneous data proper to DPCM has been solved by effective error-concealment techniques which practical application requires.
