DRM-protected multimedia

DRM

DRM (Digital Rights Management) refers to any of several encryption technologies used to protect digital media (such as audio, video and images) against unauthorized copying, and to control the distribution of the content.

There are currently five major DRM standards. All S60 3rd Edition, Feature Pack 1 devices support OMA DRM (Open Mobile Alliance DRM). A limited number of devices also support WMDRM (Windows Media DRM).

Note: Media formats, such as .3gp and .mp3, and DRM encryption are separate technologies.

Note: When developing your application, remember that OMA DRM and WMDRM are not interoperable.

OMA DRM

OMA DRM (Open Mobile Alliance Digital Rights Management) is a mechanism used for protecting distributed content. Using DRM, the content can be accessed on authenticated devices depending on the usage rights set by the content owner. OMA DRM addresses the various technical aspects of this system by providing appropriate specifications for content formats, protocols, and a rights expression language.

There are currently two standards of OMA DRM, v1.0 and v2.0, both of which are supported by S60 3rd Edition, Feature Pack 1 devices. OMA DRM v2.0 offers improved protection and support features, but due to higher licensing fee it is not as widely used as v1.0.

Nokia Mobile Internet Toolkit is an example of a tool that can be used to create mobile content with OMA DRM protection.

WMDRM

WMDRM (Windows Media DRM) 10 is a Microsoft technology for protecting and delivering media content. It is available on a computer, portable device, or network device.

A limited number of S60 3rd Edition, Feature Pack 1 devices also support WMDRM. However, DRM Audio Player API does not support WMDRM and these devices can only play the content offline.
