摘要
数字水印技术作为一种信息隐藏技术已被广泛应用于广播电视和互联网流媒体中。基于该技术的音频广播监测系统可以很好地解决版权保护、错播、非法插播和干扰等问题,提高音频广播的监测效率,解决了依赖于人工监听的传统方法,保证了广播的安全播出。因此,针对广播节目内容的有效监管需求,本文阐述了一种基于单片机、CPLD和DSP的音频水印嵌入系统实现方案。
As an information hiding technology, digital watermarking technology has been widely used in radio, television and Internet streaming media. Based on this technology, the audio broadcast monitoring system can solve copyright protection, wrong broadcasting, illegal intervention and disturbance problems well, improve monitoring efficiency of audio broadcast, replace traditional manual listening methods and ensure automatic monitoring and safety broadcasting. Therefore, the audio watermarking embedding system, based on MUC, CPLD and DSP, is designed for effective regulatory requirements of broadcast program content.
