ABSTRACT:
A method for providing DRM files using caching includes identifying DRM files to be displayed in a file list in response to a request, decoding a number of first DRM files from among the identified DRM files and caching the first DRM files in a first memory space, and reading the first DRM files in the first memory space in response to the request. Then, a system displays the first DRM files as a file list in a display area. The second DRM files from among the identified DRM files other than the first DRM files are not initially decoded, and file data related to the second DRM files are cached in a second memory space. DRM files from among the second DRM files are subsequently decoded in response to a subsequent command.
