摘　　要：本文设计并实现了一个用于广播电视内容监测的视频水印算法。该算法具有脆弱性、盲检测、实现简单、运行快速的特点。脆弱性使得对视频内容的篡改会引起水印的破坏,导致水印无法提取,从而识别被篡改的视频内容;盲检测使得用户终端提取水印时无需原始视频的参与,避免了原始视频的传输或存储,降低了系统的开销;实现简单、运行快速的特点使得水印的嵌入和提取不会影响广播电视内容的播出,满足实时监测的要求。测试结果表明该算法能够对广播电视内容进行实时监测,及时发现恶意篡改的视频内容。In order to find the tampering immediately,a video watermark algorithm for broadcast content monitoring is proposed in this study.The algorithm has the characteristics of vulnerability,blind detection,simple implementation and fast operation.Vulnerability makes the tampering of video content will cause the destruction of the watermark,which cannot be extracted so as to identify the tampered video content.Blind detection allows users to extract the watermark without the participation of the original video,which avoids the transmission or storage of the original video and reduces the system cost.The features of simple implementation and fast operation make embedding and extracting the watermark will not affect the broadcasting,which can meet the requirements of real-time monitoring.The test results show that the algorithm can monitor the content of broadcast in real time and can find the malicious tampering immediately.
