Digital Audio Control Protocol
（重定向自DACP）
Digital Audio Control Protocol (DACP) is a protocol used by the iTunes and other audio player and server applications on Mac, Windows and Linux computers, enabling remote control by mobile devices such as iPhone and Android phones and tablet computers. By connecting the personal computer to loudspeakers the mobile device is used as a two-way remote control, allowing selection and control of music playback within a traditional listening environment such as a home or apartment.
