Drm Media Conversion Technology

DRM protection is widely used by hardware manufacturers, publishers, copyright holders and individuals to limit an unauthorized playback of their media. The use of DRM is still controversial. Proponents argue that DRM was pointed to suppress media piracy, while the opponents insist that it's just a perfect marketing course indeed. Their position is essentially that copyright holders are restricting the rights of paid customers in ways not covered by existing laws.

In practice, the protected music and video files are encrypted and locked by playback license authorization. The DRM license may prevent playback, copying and conversion to other audio or video formats by end users. Every playback device, for example portable MP3 player, mobile phone or PC, must be individually authorized by an online license server. So the users of music service are not able to play their DRM-protected music or movie on any new digital player or computer. Digital rights management technology is being used by such digital media stores as Apple iTunes, Napster To Go, Rhapsody, CinemaNow, Amazon Unbox and many others.

Fortunately, there are several conversion techniques implemented by different DRM converter products. Technically all you can hear or see can be recorded, so protected media converters provide the way to re-record your music or video files automatically and almost losslessly. The predecessor of modern DRM media conversion methods was the technology for creating digital recordings from analog sources, the oldest and most lossy method. The accuracy here strongly depends on the reproduction methods used. The software based on this technology ("Analog Audio Loop") usually requires special cord to connect line-in and line-out of audiocard.

Virtual CD-RW device conversion technology, used by NoteBurner, might be reliable on slow computers. Virtual CD-RW device captures the data and sends it to a DRM converter which saves it to regular audio files. In other words this conversion technology simulates the burning and ripping process.

The most universal, lossless and popular technology is "Virtual Audio Device". This kind of software installs virtual soundcard and re-records your music through virtual speakers. The market leaders here are SoundTaxi and Tunebite. Using this software you can convert several DRM-protected audio files simultaneously, each through its own virtual sound device. Sure, the multiple audio file conversion mode requires solid system resources. On the other hand, running quad core processor and with plenty of RAM you'll be able to convert up to 15 files in parallel.
