Method and device for DRM file conversion
View Patent ↗A method for DRM file conversion is provided in an embodiment of the present disclosure, including: parsing a multipurpose Internet mail extensions (MIME) parameter in a rights type system of a DRM file to obtain file types and rights formats to which the DRM file can be converted; and converting, according to the file types and rights formats to which the DRM file can be converted, the DRM file into a file type and a rights format in the file types and rights formats to which the DRM file can be converted, where the file type and rights format is supported by a DRM system that receives the DRM file. A device for DRM file conversion is provided in another embodiment of the present disclosure.
1. A method for Digital Rights Management (DRM) file conversion, the method comprising:
parsing a multipurpose Internet mail extensions (MIME) parameter according to the rights type system of the DRM file to obtain file types and rights formats to which the DRM file is to convert, wherein at least one multipurpose Internet mail extensions (MIME) parameter is added to a rights type system of the DRM file, and the MIME parameter comprises file types and rights formats to which the DRM file is to convert; and
converting, according to the file types and rights formats, the DRM file into a file type and a rights format which is supported by the DRM system that receives the DRM file,
wherein the MIME parameter is included in a system element, and the procedure for obtaining the file types and rights formats to which the DRM file is to convert comprises:
parsing an export element to obtain the system element;
parsing the obtained system element to obtain system IDs of a DRM system that receives the DRM file; and
parsing the MIME parameter according to a system ID selected, by a user, from the obtained system IDs, to obtain the file types and rights formats to which the DRM file is to convert.
2. The method according to claim 1 , wherein each MIME parameter comprises a file type element and a rights format element, and
the file type element comprises the file types to which the DRM file is to convert; and
the rights format element comprises the rights formats to which the DRM file is to convert.
3. The method according to claim 2 , wherein when multiple MIME parameters exist, the MIME parameters in the rights type system of the DRM file are parsed respectively to obtain all file types and rights formats to which the DRM file is to convert, and the DRM file is converted, according to an instruction entered by a user, into a file type and rights format supported by a DRM system that receives the DRM file in the file types and rights formats to which the DRM file is to convert.
4. A non-transitory computer-readable storage medium having stored codes and instructions, when executed by a processor, causes a computer to perform a method for Digital Rights Management (DRM) file conversion, the method comprising:
parsing a MIME parameter according to the rights type system of the DRM file to obtain file types and rights formats to which the DRM file is to convert, wherein at least one multipurpose Internet mail extensions (MIME) parameter is added to the rights type system of the DRM file, and the MIME parameter comprises file types and rights formats to which the DRM file is to convert; and
converting, according to the file types and rights formats, the DRM file into a file type and a rights format which is supported by the DRM system that receives the DRM file,
wherein the MIME parameter is included in the system element, and parsing an MIME parameter in a rights type system of a DRM file to obtain file types and rights formats to which the DRM file is to convert further comprises:
parsing the export element to obtain the system element;
by parsing the system element obtained, obtaining system IDs of the DRM system that receive the DRM file; and
parsing the MIME parameter according to a system ID selected by the user from the obtained system IDs, to obtain the file types and rights formats to which the DRM file is to convert.
5. The non-transitory computer-readable storage medium according to claim 4 , wherein each MIME parameter comprises a file type element and a rights format element, and
the file type element comprises the file types to which the DRM file is to convert; and
the rights format element comprises the rights formats to which the DRM file is to convert.
6. The non-transitory computer-readable storage medium according to claim 5 , wherein when multiple MIME parameters exist, the MIME parameters in the rights type system of the DRM file are parsed respectively to obtain all file types and rights formats to which the DRM file is to convert, and the DRM file is converted, according to an instruction entered by a user, into a file type and rights format supported by a DRM system that receives the DRM file in the file types and rights formats to which the DRM file is to convert.
