Market and revenue possibilities
As streaming means “seeing the product without
having it”, it can be extensively used in the music
and film industry. There are also great revenue
possibilities for subscription-based content; for
example, the user can subscribe to several on
demand services such as news and traffic
information.
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 processing power
has been dedicated to the games, the large 65k
colour screen and more sophisticated graphics
with Java 3D and the Mascot API. 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
applications. This is a great way to upgrade the
game gallery, install work-supportive programs and
personalize the phone.
SMIL
SMIL stands for Synchronized Multimedia
Integration Language and is pronounced “smile”.
SMIL is an advanced XML-based protocol, and
Sony Ericsson’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
create 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
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
on the display.
Media types
There are certain media formats that support
continuous media (speech, audio and video). The
following media types are supported for SMIL:
• AMR narrow band speech codec MIME media
type
• MPEG-4 AAC audio codec MIME media type
• MPEG-4 video 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
