One File, Different Rights
With DRM-X, a retail Website can offer consumers different options when they purchase their contents. For example, by paying a small fee, consumers can play the song for one month while by paying a larger fee, they can play the song forever and can also own the rights to transfer the song to a portable device. If they choose the latter, the DRM-X will issue a license for them which do not contain expiration date, they are also permitted to play the file on a portable audio device.
