摘要
提出了一种基于压缩域数字视频水印概念的新型摄像机-多功能水印摄像机。它由视频采集设备(包括摄像头和视频采集卡)、视频压缩及水印嵌入设备和压缩码流存储及网络传输设备(包括USB串口、移动硬盘、触摸屏和以太网口)组成。摄像机在执行视频压缩的同时以内置方式嵌入用于版权保护、内容认证和保密通信的多功能数字水印信息。由于摄像机执行实时的视频采集、压缩和水印嵌入,极大提高了视频内容的完整性和版权的置信度。测试数据表明了该摄像机的有效性。
A new concept multipurpose watermarking camera is introduced based on the compressed domain video watermarking.It comprises of video capture device including camera tube and capture card,video compressing and watermark embedding device,and compressed bitstreamstorage device containing USB Series interface,mobile disk,touch screen,and LAN interface.When compressing video,digital watermark is inserted into the compressed video to be used for copyright protection,content authentication,and convert communication.The proposed camera can provide integrity and high credible video content because of its real-time video capturing, compressing,and watermark embedding.The test data demonstrate the effectiveness of our camera.
