White Paper Z600
10 September 2003
Audio
With the sound recorder function in the Z600, it is
easy to make a voice recording, for example a per-
sonal rendition of “Happy Birthday”. The audio
function in the Z600 also allows downloading of
sounds and melodies.
Themes
With themes, the user can change the appearance
of the display, for example the background colours
and the background picture. The phone comes
with a number of pre-defined pictures, and it is
possible to download additional themes. The maxi-
mum number of themes is limited only by the
amount of memory.
MMS (Multimedia Messaging Service)
One of the key features in the Z600 is the Multime-
dia Messaging Service (MMS), this is expected to
become the preferred messaging method of mobile
terminal users, since there are virtually no limits to
the content of an MMS transmission. An MMS
message (also known as a Picture Message) from
the Z600 can contain text, pictures, graphics, ani-
mations, images, audio clips and ring melodies. For
more detailed information, see “Multimedia mes-
saging service” on page 53. For third-party devel-
opers’ information, please visit
www.SonyEricsson.com/developer and look for the
MMS Developers’ guidelines.
Defined and specified by 3GPP as a standard for
third generation implementation, MMS completes
the potential of messaging. Sending digital post-
cards and PowerPoint-style presentations is
expected to be among the most popular user appli-
cations of MMS. Eagerly awaited by young users in
particular, MMS is projected to fuel the growth of
related market segments by as much as forty per-
cent.
Using the Wireless Application Protocol (WAP) as
bearer technology and powered by the high-speed
transmission technologies EDGE, GPRS and UMTS
(W-CDMA), Multimedia Messaging allows users to
send and receive messages that look like Power-
Point-style presentations. The messages may
include any combination of text, graphics, photo-
graphic images, speech and music clips. MMS
messaging will serve as the default mode of mes-
saging on all terminals, making total content
exchange second nature. From utility to sheer fun,
it offers benefits at every level and to every kind of
user.
