摘要：This paper presents an RMP (Rights Management and Protection) system for Digital Broadcasting Based on Home Servers to be used with receivers and home storage devices. We clarified the requirements required for rights protection of contents in Digital Broadcasting Based on Home Servers, and developed an RMP system that meets those requirements. This RMP system enables rights protection and advanced access control (term of validity, usage and charge condition, etc.) of content stored on home storage devices. We have also proposed a method for multiplexing scramble keys synchronous with MPEG-2 TS video packets, to achieve a non-linear playback function of contents encrypted by the developed RMP system. We confirmed that non-linear playback and trick-play function of contents encrypted by the developed RMP system can be processed in real time.
