Using OMA DRM 1.0

OMA DRM 1.0 offers three different formats for applying protection, as described in TABLE 2-3.

TABLE 2-3OMA DRM 1.0 Formats

DRM Type

Description

 

 

Forward Lock

Content is delivered with basic copy protection. Content cannot be

 

forwarded to another device.

Combined Delivery

Content is delivered together with basic copy protection and

 

additional usage rights are included. Content cannot be forwarded

 

to another device.

Separate Delivery

Encrypted content is delivered separately from the digital rights.

 

Content can be forwarded to another device.

 

 

For a thorough discussion of OMA DRM 1.0, go to http://www.openmobilealliance.org/. The default setting for OMA DRM 1.0 in the Content Delivery Server is Disabled. You can enable this DRM after deployment (see “Enabling and Disabling a DRM” on page 26 for more information).

If OMA DRM 1.0 is selected as an available DRM type, the system administrator can set a preference for the type of rights delivery format, as follows:

Only combined delivery is used

Only separate deliver is used

Separate delivery is used whenever possible, otherwise, combined delivery is used

The last preference option provides flexibility in providing digital rights protection with content. Work with your system administrator to determine what rights delivery preference to use, if desired. The preference is set in the configuration properties file for the Content Delivery Server.

Content with Forward Lock or Combined Delivery is available to compliant devices that support Combined Delivery. Compliant devices that do not support Separate Delivery cannot receive content that has Separate Delivery unless the delivery preferences are set to allow compliant devices to receive content using Separate Delivery by using Combined Delivery.

The possible associations of DRM types to content types are listed in Appendix B. See “Adding a Content Type” on page 32 for information on how to assign DRM types to content types.
