That is why the key word to describe MMS content is rich. Complete with words, sounds and images, MMS content is endowed with the user’s ideas, feelings and personality. An MMS message can contain one or more of the following:
Text
As with SMS and EMS (Enhanced Messaging Service), an MMS message can consist of normal text. The length of the text is unlimited. The main difference between an EMS and MMS message is that in an MMS message, text can be accompanied not only by simple pixel images or melodies but by photographic images, graphics, audio clips and video clips.
Templates
The phone comes with a number of MMS pre- defined templates, for example templates for birthday cards, meeting requests etc.
Audio
MMS provides the ability to send and receive full sound (MIDI, MP3, iMelody, AMR) messages. Not only can users share a favourite song or ringtone with a friend, they can also use the mobile phone to record a sound and send it along with a message. As sound includes speech as well as music, this extra dimension to an MMS message allows for a spontaneous and immediate personal expression in communication messaging. Rather than sending a downloaded birthday jingle in EMS, a user can, for example, send a clip of his or her own personal rendition of “Happy Birthday”. The phone supports the MIDI format.
Pictures and themes
By using the integrated camera, users can take a picture or video clip and immediately send it to a recipient. The ability to send pictures is one of the most exciting attributes of MMS, as it allows users to share meaningful moments with friends, family and colleagues.
Mobile picture transmission also offers inestimable utility in business applications, from sending on- site pictures of a construction project to capturing and storing an interesting design concept for later review. Editing a picture by adding text allows users to create their own electronic postcards, an application that is expected to substantially cut into the traditional postcard market.
