Abstract: A compressed digital audio signal is transmitted from an audio source along a connection wire to an audio receiver. The digital audio signal can encode digital audio data having different sampling frequencies, frames sizes, and other information. The audio receiver that receives the digital audio signal can decode and convert the compressed digital audio signal into multiple synchronized analog signals, which are used to drive multiple speakers. The audio receiver may also synchronize the audio data with associated video data so that the audio playback and video playback are “in sync”, despite delay introduced by the audio signal decoding at the audio receiver.

Abstract translation: 压缩的数字音频信号从音频源沿着连接线传输到音频接收器。 数字音频信号可以编码具有不同采样频率，帧大小和其他信息的数字音频数据。 接收数字音频信号的音频接收器可以将压缩的数字音频信号解码并转换成多个同步的模拟信号，用于驱动多个扬声器。 音频接收器还可以使音频数据与相关联的视频数据同步，使音频播放和视频播放“尽管同步”，尽管由音频接收器处的音频信号解码引入了延迟。
