摘要
随着视频编码技术的发展,高清/超高清视频内容逐步占据主流市场,加之开放的互联网视频环境,对视频内容版权保护提出了比CA更高的需求。DRM技术对视频内容保护的边界可以贯穿视频内容的整个生命周期,满足运营商对视频内容保护的各种需求。针对运营商为防范运营过程中出现DRM系统故障导致业务意外中断,部署多个DRM系统在运营商平台上以最小的网络资源同时运行,运营商可以根据需要选择选用合适的DRM系统终端,并可以把不合适的DRM替换掉,降低运营风险,提出了一种多DRM系统协同的内容版权保护实现方法。
With the development of video coding technology, high-definition/ultra-high-definition video content has gradually occupied the mainstream market. In addition, the open Internet video environment has put forward a higher demand for video content copyright protection than CA. The boundary of DRM technology for video content protection can run through the entire life cycle of video content, meeting the various needs of operators for video content protection. In order to prevent the business from being interrupted unexpectedly due to the failure of the DRM system in the operation process, multiple DRM systems are deployed on the carrier platform with the minimum network resources. The operator can select the appropriate DRM system terminal according to the needs and be able to replace the inappropriate DRM to reduce the operational risk. This paper proposes a multi-DRM system collaborative content protection implementation method.
