摘要

我们描述了一种新的压缩域(MPEG-2)方法来实现广播或多播环境下的视频安全和版权保护。该方法有效地解决了广播机构对单拷贝传输和多唯一拷贝版权保护的矛盾需求。该方法支持动态连接和离开，并依赖于鲁棒的不可见水印、屏蔽和条件访问技术来达到预期的效果。

We describe a novel compressed domain (MPEG-2) method to achieve video security and copyright protection in a broadcasting or a multicasting environment. The proposed method is an efficient solution for resolving the conflicting requirements of single copy transmission for broadcasting and multiple unique copies for copyright protection by the broadcaster. The new method supports dynamic join and leave and it relies upon robust invisible watermarking, masking and conditional access techniques to achieve the desired result.
