OMA DRM Forward Lock/Combined Delivery protected content on a Memory Stick™ cannot be used in another device other than the device it was saved on. Only Separate Delivery packages can be used on another device, after obtaining access keys to use the content on the new device. Thus, the Memory Stick™ is one way of distributing Separate Delivery content to several users. Access keys to use the content can never be distributed from user to user (device to device). Access keys always have to be obtained directly from the rights issuer.
White Paper M600
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 V1 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 M600 can be personalised by the user in one of the following ways:
•Update the User Interface using services, such as,
•Use
•Via Over the Air (OTA) configuration, initiate by the operator, user or IT helpdesk.
Alterations to the appearance of many of the screens may be simply carried out through changing the phone's Theme. New Themes may be loaded on to the M600 from the Internet and other sources.
Background and application shortcuts
User can set a static image, or animated GIF, to be the background 'wallpaper' for the standby screen. Image size is 208 x 189 pixels and formats JPEG, GIF, BMP, WBMP, MBM and PNG are supported.
Larger images, will be resized to fit.
The application shortcut buttons may be personalized by the user. The user may also select to have them displayed all the time.
Screen Saver
A 'screen saver' image is displayed after a period of inactivity. The user can switch this facility on and off and select the delay period before the screen saver is displayed. Image size is 208 by 320 and the format is the same as the background image above. Note that use of animated GIF increases power consumption.
Device lock may be used in combination with the screen saver. Upon pressing a button or touching the screen, the user will be prompted to activate keys and/or enter the device lock code.
When the screen saver is deactivated, the M600 will revert to the state it was in before the screen saver was activated.
