Hi,

I am investigating a MP3 playback system. In this, I need to support 
playing DRM(Digital Right Management) enabled MP3 files. When I 
searched in the web I find DRM info related to microsoft, apple etc; 
but these are practically for .wma and .aac formats.

What is the specific (practical)DRM technique for MP3 files? Can 
somebody provide me info/links?

Also do you know any company providing library/services in this field, 
specifically on Blackfin processors?

Regards
Sham
