White Paper M600
53 February 2006
DRM
Digital Rights Management, DRM, is a technology
that enables secure distribution, promotion, and
sale of digital media. Examples of such content
include music, personal images, wallpapers and
screen savers with themes from films, ringtones
from musical artists, and branded games. In other
words, content providers can control how users
may use different types of content in devices, such
as mobile phones, phones or PDAs. Content
providers can also control the use of content in
related services, such as MMS and download.
Sony Ericsson is actively focusing on technology
standardization for the DRM concept, and supports
the ongoing standardization work and activities of
the OMA (Open Mobile Alliance). Sony Ericsson is
fully committed to open standard solutions in the
mobile environment and is a principal driver of
many open standard initiatives. This will ensure the
interoperability of mobile terminals in the DRM area
and also result in a strong, competitive DRM
standard.
FWL – forward lock
M600 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 M600 as part of an MMS message or
via HTTP download. M600 supports OMA
Download. More information is available at
www.SonyEricsson.com/developer.
CD – combined delivery
M600 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
M600 supports OMA DRM Separate Delivery.
Content and associated access keys are received
as separate DRM packages, either simultaneously
or at different points in time. This enables the
distribution of content to other users and has the
same possibilities to control usage of the content
as exist with Combined Delivery/Forward Lock.
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 protected content packages can
be transferred to the Memory Stick™, thereby
enabling storage of large amounts of content.
Language Change Utility Enables the user to load a different language from the CD-ROM and switch
the phone UI to that language, assuming the specific phone supports this.
The language files are also available at www.SonyEricsson.com/support
Internet Wizard Wizard for creating 3G, GPRS and HSCSD settings for Internet and email
connections.
Drivers Drivers for using the phone as a modem over infrared, Bluetooth or Cable.
