•(Sony/Philips Digital Interface) is a standard audio transfer file format. It is usually found on digital audio equipment such as a DAT (Digital Audio Tape) machine or audio processing device. It allows the transfer of audio from one file to another without the conversion to and from an analog format, which could degrade the signal quality.

•The most common connector used with an S/PDIF interface is the RCA connector, the same one used for consumer audio products. An optical connector is also sometimes used.

数字音频接口 I2S

•I2S (Inter-IC Sound) is a serial bus (path) design for digital audio devices and technologies such as compact disc (CD) players, digital sound processors, and digital TV (DTV) sound. The I2S design handles audio data separately from clock signals. By separating the data and clock signals, time-related errors that cause jitter do not occur, thereby eliminating the need for anti-jitter devices. An I2S bus design consists of three serial bus lines: a line with two time-division multiplexing (TDM) data channels, a word select line, and a clock line.
