P800/P802
White Paper, January 2003
52
The user may shorten slide duration to less than
the duration of the audio track. If there is audio
on the next slide, the audio will be stopped and
the track for the next slide will be played.
If there is no audio on the next slide, the audio
track will continue playing until it finishes or a
later slide is displayed which has its own audio
track.
If Page time is un-checked, then the display
time for the text can be set to shorter than the
page duration.
Special case where audio can continue playing
after the end of a slide.
Templates
A template is a predefined message containing one or more slides. It may be modified by the
user to quickly produce an attractive message. The Blank template is the default – in this case
nothing is pre-selected and the user may create slides as required.
Users may store a favourite message as a template. Templates can also be deleted.
The P800 comes with 8 pre-defined templates, all of which have sound and an animated image
(GIF format, 160 x 120 pixels). These and other useful content pre-loaded by Sony Ericsson are
described in ‘Personalisation and Customisation’ later in this document.
Notification and download
Incoming multimedia messages are normally notified to the user as soon as they arrive, in the
same way as text messages. Basic download options are:
• On – always download the message
•
Home only – messages are downloaded only when connected to the home network.
•
Off – download messages manually.
Additionally, filters may be set, based on:
•
Message size
• Message class (Advertisement, Information)
•
Anonymous sender (exclude messages from senders not listed in Contacts, or where
sender information has been hidden)
Interoperability and Conformance
MMS is a very flexible and extendable specification. To help mobile operators launch MMS
services that are consistent and reliable, Sony Ericsson, Nokia, Motorola, Siemens, CMG,
Comverse and Logica have worked together to produce a Conformance Specification (‘MMS
Conformance Document V2.0.0’). This provides additional guidelines that are intended to make
sure that messages sent between different products are played back correctly.
The main areas covered by the specification are:
•
Picture formats (JPEG/JFIF, GIF, WBMP) and size (160 x 120 pixels)
• Sound format (AMR)
•
Slide layout (2 objects plus sound, layout is the same for all slides)
• SMIL subset (all timing elements are within a slide)
• Maximum message size of 30kbytes
