Method and system for providing digital rights management files using caching
View Patent ↗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.
1. A method for managing digital rights management (DRM) files, comprising:
identifying DRM files to be decoded;
decoding a first portion of the DRM files;
caching the decoded DRM files in a memory;
reading the decoded DRM files according to a first command; and
displaying the decoded DRM files in a file list.
2. The method of claim 1 , further comprising:
caching file data related to a second portion of the DRM files in the memory.
3. The method of claim 2 , further comprising:
reading the file data related to the second portion of the DRM files in the memory according to a second command; and
displaying the file data related to the second portion of the DRM files in the file list.
4. The method of claim 1 , wherein caching the decoded DRM files in the memory comprises storing the decoded DRM files in the memory.
5. The method of claim 1 , wherein a number of DRM files in the first portion of DRM files is based on a number of file list slots that are capable of being displayed on a display area.
6. A computer comprising a memory and a central processing unit to perform program instructions stored on a computer-readable medium, the program instructions to implement the method of claim 1 .
7. A system to manage digital rights management (DRM) files, comprising:
a file identification unit to identify DRM files to be decoded;
a memory caching unit to decode a first portion of the DRM files, and to cache the decoded DRM files in a memory;
a file reading unit to read the decoded DRM files stored in the memory; and
a display unit to display the decoded DRM files in a file list.
8. The system of claim 7 , wherein the memory caching unit caches file data related to a second portion of DRM files in the memory.
9. The system of claim 8 , where the file reading unit reads the file data related to the second portion of DRM files in the memory, and the display unit displays the file data related to the second portion of DRM files in the file list.
10. The system of claim 7 , wherein a number of DRM files included in the portion of DRM files is based on a number of file list slots that are capable of being displayed on the display unit.
11. A mobile terminal, comprising the system of claim 7 .
