摘要： A system for processing DRM-enabled files includes a playback device and a software module. The software module includes a license-downloading module, a license-transforming module, a decryption module and an encryption module. The license-downloading module is configured to download a first license from a license server to a computer. The license-transforming module is configured to convert the first license to a second license. The decryption module is configured to decrypt a first DRM-enabled file of the computer into a raw file with a first decryption key. The encryption module is configured to encrypt the raw file into a second DRM-enabled file with a second encryption key. The playback device is configured to decrypt the second DRM-enabled file with the second license. The method of the system is also provided.

摘要： A Redundant Array of Independent Disks (RAID) system is disclosed in this invention. The RAID system includes a plurality of data storage units and a parity storage medium. The parity storage medium can be singular storage hardware or a logical storage module including multiple storage units. The parity storage medium cooperates with the data storage units to form a RAID. The parity storage medium is used for storing parity information of the RAID. A first write speed of the parity storage medium is faster than a second write speed of each data storage unit.

摘要： A block-based seeking method for Windows Media Audio (WMA) stream can be implemented in a portable electronic device with a first processor and a second processor. The first processor initially reads a WMA stream from a block-based storage device. Next, the WMA stream is transmitted to a memory of a second processor block by block. The first processor generates and transmits a block number before it transmits a block of data. Next, the second processor decodes the WMA stream packet by packet. If a discontinuous block number occurs, a desired position of the WMA stream is sought according to the discontinuous block number. Next, the second processor outputs decoded samples of the WMA stream.
