As of June 19, 2009, Microsoft has made changes to the way Windows Media DRM (WMDRM) for Devices is licensed. These changes provide device manufacturers with cost-effective technology for today's devices while facilitating future access to a richer set of DRM features and other improvements via use of the PlayReady code base. This WMDRM Device Transition Program provides benefits both to existing licensees of WMDRM for Devices as well as to new licensees—whether you wish to use just WMDRM functionality, or you wish to take advantage of the many new features that PlayReady provides. Under the WMDRM Device Transition Program, a new licensing agreement enables existing licensees of WMDRM for Devices technology to continue to develop and/or distribute devices that support WMDRM, on the existing WMDRM code base, after expiration of your current agreement. This enables you to extend the use of your WMDRM for Devices code base for an additional three years, which gives you time to study the PlayReady code base and migrate to it when your engineering teams are ready. Alternatively, existing WMDRM for Devices licensees (or any new licensee) can license WMDRM functionality—or the full PlayReady functionality—on the PlayReady code base today and take advantage of the numerous improvements Microsoft has made to the PlayReady code base. PlayReady is the successor technology to WMDRM and provides many new advanced and frequently-requested features, such as domain control, embedded licenses, and the ability to protect a wide range of content types and formats, all on a new and improved code base. PlayReady is also backwards-compatible with WMDRM for Devices, meaning that devices you build will be compatible with content that works with WMDRM-based devices. Even if you only use the PlayReady code base to provide WMDRM functionality for devices, you will enjoy performance and application development benefits compared with using the WMDRM for Devices code base.
