White Paper T310/T312

MMS objects
Although MMS is a direct descendant of SMS, the
difference in content is dramatic. The size of an
average SMS message is about 140 bytes, while
the maximum size of an MMS message is limited
only by the memory. That is why the key word to
describe MMS content is rich. Complete with
words, sounds and images, MMS content is
endowed with the user’s ideas, feelings and
personality.
An MMS message can contain one or more of the
following:
Text
As with SMS and EMS, an MMS message can
consist of normal text. The length of the text is
unlimited, and it is possible to format the text. The
main difference between an EMS and MMS
message is that in an MMS message, text can be
accompanied not only by simple pixel images or
melodies but by photographic images, graphics,
audio clips and in the future, video sequences.
Templates
The T310/T312 comes with a number of MMS pre-
defined templates, for example templates for
birthday cards, meeting requests etc.
Audio
MMS provides the ability to send and receive full
sound (iMelody, MIDI and AMR) messages. Not
only can users share a favourite song or ring signal
with a friend, they can also use the mobile phone to
record sound and send it along with a message.
Because sound includes speech as well as music,
this extra dimension of an MMS message makes
for enhanced immediacy of expression and
communication. Rather than sending a
downloaded birthday jingle in EMS, for example, a
user can send a clip of his or her own personal
rendition of “Happy Birthday”.
Pictures and themes
By using either a digital camera attached to the
T310/T312 with a snap-on camera accessory,
users can take a snapshot and immediately send it
to a recipient. The ability to send pictures is one of
the most exciting attributes of MMS, as it allows
users to share meaningful moments with friends,
family and colleagues.
Mobile picture transmission also offers inestimable
utility in business applications, from sending on-
site pictures of a construction project to capturing
and storing an interesting design concept for later
review. Editing a picture by adding text allows
users to create their own electronic postcards, an
application that is expected to substantially cut into
the traditional postcard-sending market.
Themes (downloaded or pre-defined) can be
exchanged via MMS.
SMIL presentations
SMIL stands for Synchronized Multimedia
Integration Language and is pronounced “smile”.
SMIL in the T310/T312 allows the user to the create
and transmit PowerPoint-style presentations on the
mobile device. SMIL is an advanced XML-based
protocol, and Sony Ericsson MMS supports a
subset of this protocol. Using a simple media
editor, users can incorporate audio and animated
GIFs along with still images, animations and text to
assemble full multimedia presentations.
The idea of SMIL is to allow the user to customize
the page timing in Powerpoint-style presentations.
The user can decide in which order the image and
text will be displayed, as well as for how long the
images and text lines are to be shown in the
display
PIM communication with MMS
With MMS in the T310/T312, it is easy to send and
receive business cards (vCard) and events.
