phones from the oldest to the newest. Some companies in the mobile phone industry have
developed their own messaging technologies, which only work with their own phone models.
Network operators are in favour of EMS because it is universal – many of the major mobile phone
manufacturers are constructively improving and developing the EMS standards even further for
implementation in their products.
Examples of EMS contents and applications
A wide range of contents, applications and services may be developed. Below is a list of
examples and areas where messaging can be enhanced with EMS:
• User-to-user message
•
Message notifications for voicemail, e-mail, unified messaging.
• Illustrated news & commercials
EMS Media Objects in the P800
Sounds and melodies
EMS sound is in the form of simple melodies according to the iMelody standard. Multiple sounds
may be included in a message.
A library of sounds is included with the P800. Additional sounds may be copied from incoming
EMS messages and pasted in to a new message. Sounds from received messages can also be
stored in the ‘Melody’ folder within the EMS ‘Insert object’ menu.
EMS also has pre-defined sounds such as “Chime high” and “Notify.” Rather than sending the
complete sound to the receiving phone, EMS sends a ‘token’ instructing the receiving phone to
play that sound according to its own library. When the P800 receives a message that includes an
EMS pre-defined sound, it will be played in polyphonic form.
The P800 does not include a melody composer for EMS, neither is it possible to set ringtones
from melodies received in EMS messages as the P800 is better suited to polyphonic ringtones.
Pictures and Animations
EMS pictures and animations are in the form of small bitmaps. These are transmitted in binary
black and white (meaning that there are no scales of grey in between). Multiple pictures can be
added to a message.
8 x 8 pixels 16 x 16 pixels 32 x 32 pixels
A library of pictures is included with the P800. Images from received messages may also be
saved to the ‘User Defined’ folder within the EMS ‘Insert object’ menu. These images can then be
edited and re-used.
Pictures may be added to a message by copying and pasting them from received messages.
New images can be created using a simple grid and pen editor. Animations may not be created or
edited.
EMS also has pre-defined images such as smileys. Rather than sending the bitmap, a simple
token is sent to instruct the receiving phone to display the pre-defined image. The P800 will
