Abstract: 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.

Abstract: A device and a method for changing a DRM algorithm of streaming data are provided to enable various DRM client terminals to use a streaming service encoded through various DRMs freely by changing the DRM algorithm stored in the streaming data into a different DRM algorithm if necessary. A plurality of parsers with an N-level receive and parse the streaming data. The plurality of packetizers with the N-level generate the streaming data by packetizing the parsed streaming data. A decoder decodes the data encoded by the n-th level parser among the N parsers according to a first DRM algorithm by connecting to the n-th parser. An encoder encodes the decoded data according to a second DRM algorithm by connecting to the m-th level packetizer among the N packetizers. A path manager manages a path based on m and n to enable the streaming data to be parsed/packetized by the minimum number of parsers and packetizers.
