P800 Smartphone
White Paper, May 2002
34
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)
• Minimum supported message size of 30kbytes
The P800 has much greater capability than that stated above. The user may therefore choose
whether to create and send messages that are ‘Conformant’, or to build and send ‘Enhanced’
messages that contain richer objects.
In ‘conformant’ mode, the user may only select media objects that are within the specification.
Images will be re-scaled to 160 x 120. Total message size will be limited to 30kbyte.
In ‘Enhanced’ mode, the user may select a wider range of objects (for example, WAV sound
clips). Images will not be re-scaled before sending.
The P800 may also be set to build messages in ‘Enhanced’ mode, yet warn the user if the
message goes outside the conformance criteria.
When non-conformant messages are received, they will be displayed within the capability of the
SMIL player. If the message is edited, objects may be saved, replaced or deleted (but no new
objects added) and conformant slides may be added.

The MMS player will render all of the above formats. The display window for images is 200 x 120
pixels in FC mode and 200 x 200 pixels in FO mode. These are the optimal sizes for images
where MMS messages are composed specifically for the P800. Incoming images larger than this
will be re-scaled to fit within the window, preserving aspect ratio.
When composing an MMS, the user may select any of the media formats when in ‘non-
conformant’ mode. In ‘conformant’ mode, only the indicated formats will be accepted for inclusion
in a message.
