| Abstract: | The characteristics and differences of different DRM standards such as OMA,Microsoft,Intertrust,and ChinaDRM were compared.The requirements of DRM applications were presented.The key technologies of DRM were analyzed.Based on the high-tech set-top box commonly used in the industry,the architecture of DRM protection in IPTV high-definition video was designed.The hardware trust root of high security set-top box,remote download terminal key,double-encrypted content key and other mechanisms was put forward innovatively.Finally,the business process of decrypting DRM content was formulated and an implementation case was given. |
