OpenMG is a SDMI-compliant digital rights management system by Sony. It is designed for audio files in ATRAC3 format. The compliant software, e.g. 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.
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, e.g. 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.
Famous quotes containing the word open:
“The child ... stands upon a place apart, a little spectator of the world, before whom men and women come and go, events fall out, years open their slow story and are noted or let go as his mood chances to serve them. The play touches him not. He but looks on, thinks his own thought, and turns away, not even expecting his cue to enter the plot and speak. He waits,—he knows not for what.”
—Woodrow Wilson (1856–1924)
