摘要
为了解决正版高清视频节目的网络授权问题,对高清视频文件的网络传输实现常规加密设计,并提出一种以网络为信息加密密文载体,以密钥和部分视频内容为服务器管理对象的新型视频加密保护技术。针对目前广泛使用的H.264高清视频编码格式,通过分析编码层数据,设计了一种视频关键帧的抽取算法,经实验验证,算法可有效提高高清视频的加密保护。
In order to solve the genuine HD video network licensing issues and achieve conventional encryption design for network transmission of HD video files,this paper proposes a network-encrypted carrier,which is a new video encryption protection technology using keys and part of video content as part as server management objects. Aiming at H. 264 HD video encoding formats widely used at present,an extraction algorithm of video key frame is designed by alayzing coding layer data. The experimental results show that this algorithm can improve effectively the encryption protection for HD video.
