Abstract
A host device and a method of implementing Digital Rights Management (DRM) systems in a low-efficiency storage device are provided. The host device includes a plurality of DRM systems and a DRM system-shared interface module. The DRM systems provide pieces of DRM-related data and data identifiers (IDs) which identify the pieces of data. The DRM system-shared interface module adds DRM system IDs, which are used to identify the DRM systems, to the pieces of data and the data IDs, and provides results, which are obtained by adding the DRM system IDs, to a low-efficiency storage device.
