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.  

 

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.
