摘要
设计实现了一个移动流媒体条件接收系统,用以满足移动条件下高质量的视频点播和直播的需求。系统引入4层密钥管理体系,安全保密的性能强;纯软件的解决方案弥补了传统数字电视、手机电视需要硬件协助的缺陷,可移植性好。测试结果表明,该方案能够实现流媒体的实时安全通信。
A conditional access system for mobile streaming media which can meet the demands of both high-quality live and video on demand is designed. The system introduces four-level administrative mechanism for keys and contains strong security features. Pure software solutions make up the defects that traditional digital TV, and mobile TV need assistances of hardware to work. The testing results show that the system can contain secure communications for real-time streaming media.
