Gaming
Gaming is now seen as a standard
feature in mobile phones, where
Sony Ericsson promises to be a
step ahead in this regard. This is
not only due to faster download capability on the
network. There are some other reasons why the
actual gaming experience is better – the way Java
has been implemented, the fact that more process-
ing power has been dedicated to the games, the
65k colour screen and more sophisticated graphics
with Java 3D. The result is games with improved
graphics that react faster to user commands when
using the navigational key as a joystick or game
controller. The phone takes mobile gaming to new
heights.
Supporting J2ME (Java 2 Micro Edition), the phone
lets users download and run new games and appli-
cations. This is a great way to upgrade the game
gallery, install work-supportive programs and per-
sonalize the phone.
SMIL
SMIL stands for Synchronized Multimedia Integra-
tion Language and is pronounced “smile”. SMIL is
an advanced XML-based protocol, and Sony Erics-
son’s MMS implementation supports a subset of
the SMIL 2.0 protocol according to OMA MMS IOP
document version 1.2.
The use of SMIL in a product allows the user to cre-
ate and transmit PowerPoint-style presentations on
the mobile device. Using a media editor, users can
incorporate text, audio, images, video clips and
animations to assemble full multimedia presenta-
tions. 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 on the
display.
Media types
There are certain media formats that support con-
tinuous media (speech, audio and video). The fol-
lowing media types are supported for SMIL:
•
AMR narrow band speech codec MIME media
type
•
H.263 video codec MIME media type
The media types for JPEG and GIF can be used
both in the 'content-type' field in http and in the
“type” attribute in SMIL 2.0. The following media
types are to be used:
•
JPEG MIME media type
•
GIF MIME media type
All these media are pointed out by MIME (Multipur-
pose Internet Mail Extensions) types.
