initiatives. This will ensure the interoperability of mobile terminals in the DRM area and also result in a strong, competitive DRM standard.

The W950 supports OMA DRM 2.0 giving the same user experience as OMA DRM 1.0. OMA DRM 1.0 is supported as described below.

FWL – forward lock

W950 supports OMA DRM Forward Lock which is the simplest OMA DRM case, with no special access keys defined. The content is provided in a single DRM packaged file, thus protecting the content from being distributed from the device by the user. It enables a secure means for the content provider to deliver/provide content which incurs a charge. Forward Lock content will normally be received by W950 as part of an MMS message or via HTTP download. W950 supports OMA Download. More information is available at www.SonyEricsson.com/developer.

CD – combined delivery

W950 supports OMA DRM Combined Delivery/ Forward Lock. Content and associated access keys are downloaded or delivered to the user as a single DRM packaged file. This means the content, or access keys issuer, controls the extent the content can be used. As with pure Forward Lock, the user will be unable to distribute this content for use on another device.

SD – separate delivery

W950 supports OMA DRM Separate Delivery.

Distribution of the content to other users will require the recipient to obtain access keys from the rights issuer in order to use the content.

Protection properties

Content that is protected according to the OMA DRM standard is given special properties.

Content with Forward Lock protection cannot be further distributed: The user cannot send the content to other devices since the “Send to” option is disabled for media protected with Forward Lock.

All three types of protectedycontent packages can be transferred to the Medialmemory, thereby enabling the storage of large amounts of content.

OMA DRM ForwardOnLock/Combined Delivery protected content on removable media cannot be used in another device other than the device it was saved on.eOnly Separate Delivery packages can be used on another device, after obtaining access keyssto use the content on the new device. Access keys to use the content can never be distributed

Ufrom user to user (device to device). Access keys always have to be obtained directly from the rights issuer.

DRM package

DRM packaging software is typically included in the software used by the content provider. It is used to create the DRM package according to the OMA DRM standards before it is delivered to the device, including content and associated access keys.

In Japan, only files with SD protection for playback will be accepted in the Media player and in some European markets only DRM content can be used for automated use/themes such as ringtones.

Personalization

The W950 can be personalised by the user in one of the following ways:

•Update the User Interface using services, such as, M-Service.

•Use PC-based utility application.
