摘　　要：本文主要介绍数字音频水印系统的基本特点,以及LSB水印和扩展频谱水印的生成技术及其在广播系统中的不同应用。As a means of copyright protection,digital audio watermarking technology is widely studied anddiscussed recently. But audio watermarking technology requests more to hide the watermark. Thistechnology is involved in communication and information theory,audio processing,signal detection,signal processing,cryptography,data compression and computer technologies,and has not yet formed a complete theoretical systemand uniform standards. And its application in broadcasting is only in the initial stage. This article discusses the digitalaudio watermarking system's basic characteristics and the generation technology of LSB and spread spectrumwatermarks,and summarizes several applications of the two watermarking technologies in broadcasting system.
