Java™ 2 Micro Edition
With Java, you can download extra
content, for example, new
information- and entertainment-based
applications. This gives users a chance
to personalize the functions and
features in their phones, and developers the opportunity
to create new applicatons.
Gaming
Gaming is already a very popular
feature in mobile phones, and with
Java, users can add new games and
skill levels to further enhance the
entertainment value of Sony Ericsson phones.
3D Games
The Java 3D gaming software
introduces and supports cutting edge
3D graphics. Audio developments
such as 40 tones polyphonic sound
and force feedback provide a much richer experience.
With operator support, there is the possibility for
multiplayer games to play against friends. The large 1.8”
STN display can only add to a lasting gaming
experience. Downloading graphic intensive games
requiring up to 6 MB user memory is also possible with
that amount of built-in memory.
Copyright protection – DRM
DRM (Digital Rights Management) assures the rights
and copy protection of downloaded content (audio,
pictures, ringtones, video, entertainment features such as
games etc.).
Content-based services have great market potential, and
to encourage this, Sony Ericsson plans to support DRM
in all future multimedia products. Sony Ericsson regards
DRM as a key enabler for content-based services, and is
active in supporting the ongoing standardization work of
the OMA (Open Mobile Alliance). Furthermore, any
additional market requirements for DRM will be
monitored.
