Research and application of DRM technology in IPTV UHD video
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.
