Messages
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 P900
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 P900. Additional sounds may be copied from incoming EMS
messages and pasted in to a new message. Sounds from received messages can also be stored and
accessed via the Select sound dialog.
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 P900 receives a message that includes an EMS pre-defined sound, it
will be played in polyphonic form.
The P900 does not include a melody composer for EMS, but it is possible to set ringtones from melodies
received in EMS messages.
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.
A library of pictures is included with the P900. Images are stored in the 'Predefined' folder (32 x 32 pixel
images) and animations are stored in 'Predefined animations' (48 x 48 pixels). Images from received
messages may also be saved. They are stored in a subfolder (called EMS) to the internal 'Images' folder,
and available under 'Message images' within the EMS 'Select image' dialog. These images can then be
edited and re-used, new images can be created using the Enhanced image editor.
