OpenMGSDMI-compliant digital rights management system by Sony. It is designed for audio files in ATRAC3 format. The compliant software eg. Sony SonicStage is usually capable of transcoding MP3 and wav files to OpenMG/ATRAC3. The file extensions OpenMG-encrypted files use are .omg and .oma.

There has already been at least one reported case when a security update of Windows broke OpenMG-compliant software. This issue was later resolved.1

Sonicstage 3.4 includes an option to remove DRM from one's entire media library allowing unrestricted use. However this feature is disabled for copies without a license.

The compliant music organization systems eg. OpenMG Jukebox work by "checking out" and "checking in" the files to/from portable players keeping only one copy unlocked in order to hinder proliferation of copies.

(November 2010) Lock-out

The 'checking in' and 'checking out' of files is often cumbersome and risky in comparison with unprotected data. Side effects include user complaints of being locked out of their own original recordings unable to transfer them to the computer. With the combination of OpenMG with MagicGate Sony intends to restrict the files to be only moved instead of copied artificially emulating the restrictions of physical objects.citation needed However as of the most recent releases of Sonicstage files can be "checked out" of the library an unlimited number of times to a portable device without the need to "check in" any of them. Inability to read 'corrupted' ID3 tags

OpenMG modules also tend to choke on corrupted MP3 ID3 tags.2 Proprietary software

With some Sony portable audio players it is not possible to directly drag and drop the desired tracks to the device's directory structure but a considerably more cumbersome process of using Sony's own or compatible software must be performed. Non-standard Table Of Contents

OpenMG protection applied to music compact discs relies on nonstandard disc TOC. This is somewhat similar to the Cactus Data Shield scheme without the artificially introduced C2 errors.3 Notes Microsoft Help and Support: OpenMG-compliant music software does not work correctly after you apply the MS04-032 Security Update for Windows XP and for Windows 2000 RealPlayer customer support forum cdfreaks.com forum: complaints about scrambled Tables Of Contents See also MagicGate External links Sony OpenMG (incl. licenses and LGPLed id3lib) Sony OpenMG (historic) Why OpenMG
