This paper introduces the widely used digital audio interface S / PDIF , and its coding format and data structure are described in detail .

介绍了S/PDIF这种被广泛应用的数字音频接口，详细讨论了它的编码格式和数据结构。

S / PDIF Sony / Phillips Digital Interface

索尼/飞利普数字接口

The design supports a lot of audio interface protocols , such as the I2S , left-justified format , right-justified format , S / PDIF protocol and so on . 3 .

本设计支持I2S、左对齐、右对齐格式的I2S协议以及S/PDIF协议等多种音频协议。

Currently , this encoder can response to the external UART serial port interrupt to implement the encoding standard switching , and sample PCM in real time , accomplish AC-3 encoding algorithm without delay , transmit the encoded stream through S / PDIF interface .

目前，该编码器能够响应外部UART串口的中断请求来实现编码标准的切换，并能够实时采集数据，实时完成AC-3编码算法，通过S/PDIF接口实时输出编码码流。
