ESM-03: Windows(TM) DRM Embedded Security Module

The ESM-03 is targeted at Personal Media Players (PMPs) supporting Microsoft Windows DRM. Microsoft DRM also knows as PlaysForSure(tm) has become the most popular digital rights management system due to its reasonable licensing terms and comprehensive reference implementation. As designers have upgraded from audio to video capability in PMPs, the security processing has become a significant burden on the embedded processor. Designers are implementing security offload engines such as the ESM-03 to free the embedded processor for other activities.
