Supported DRM Solutions
The following three DRM solutions are supported by Motorola handsets.
•Forward Locking – Forward locking construct defined by the OMA DRM specification. Similar to NDIS implementation in MMS/EMS.
•Combined Delivery – The OMA Combined Delivery mechanism is an extension of OMA forward locking. The Combined Delivery mechanism differs by including a rights object within the DRM message that governs the consumption of the content included along with the rights object. A handset that supports Combined Delivery supports OMA forward locking.
•Separate Delivery – The OMA Separate Delivery mechanism is an extension of OMA Forward locking. The Separate Delivery mechanism differs by delivering the content and the rights object separately. The W760r/VA76r handset supports retrieving rights via WAP Push.
Download
Forward Lock files are downloaded within a DRM message. The download manager recognizes the DRM message of MIME type ‘application/ vnd.oma.drm.message’ as a valid file type.
The download manager discards any DRM message that contains more than one media object within the DRM message.
OMA Combined Delivery is downloaded within a DRM message and consists of a media object and a rights object. The download manager recognizes the DRM message MIME type and the MIME type ‘application/vnd.oma.drm.rights+xml’ as a valid file type. A single media object in the body of the DRM message, that is encoded in the following identity transfer encoding ‘7bit’, ‘8 bit’, and ‘binary,’ is accepted by the download manager.
