    摘要: Provided is a system for exchanging contents between a first DRM apparatus and a second DRM apparatus, wherein each of which belongs to different DRM domain. The first DRM apparatus includes unpackaging means for unpackaging first DRM formatted contents into clear resources, metadata, and rights expression; converting means for converting each of the clear resources, metadata, and rights expression into its own predefined neutral format, respectively; generating means for generating neutral formatted contents by combining the converted resources, metadata, and rights expression; adding predetermined header information thereto; and transmitting means for transmitting the neutral-formatted contents to said second DRM apparatus. The second DRM apparatus includes extracting means for extracting clear resources, metadata, and rights expression from the neutral-formatted contents transmitted from said first DRM apparatus; and packaging means for packaging the extracted clear resources, metadata, and rights expression into second DRM formatted contents.
