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.
