Multimedia Messaging - Digital greetings

Reacting to the enormous popularity of mobile phone messaging, Sony Ericsson has incorporated the latest messaging standard into the T300/T302, along with a colour display for an enhanced imaging experience.

Say it in words, say it with pictures, animate it, add sound. Multimedia birthday and holiday greetings are great fun to put together using the T300/T302.

With MMS, the subscription applications get more interesting, for example stock information, movie trailers and weather reports.

Polyphonic ring signals

Pleasing to the ear, polyphonic ring signals play several tones simultaneously making a more musical sound. The word “polyphony” means playing with several tones at the same time. Almost all music that we listen to consists of polyphonic melodies. Up to now, the majority of the GSM mobile phones doesn’t support polyphonic sounds and ringsignals.

White Paper, August 2002

T300/T302 users can share ring signals, and download them from the Web.

Early Ericsson mobile phones supported a proprietory non-polyphonic format called eMelody. Due to the musical limitations of eMelody, and as it became popular to create, send and download ring melodies, Ericsson and Sony Ericsson, together with other manufacturers created the more advanced non- polyphonic sound format - iMelody.

The development from the iMelody format to the MIDI format means a revolution to the sound quality. The MIDI files are small, and perfect for mobile devices, which has limited storage capacity.

MIDI - Musical Instrument Digital Interface - is a specification for a communications protocol principally used to control electronic musical instruments. MIDI is today a well known standard used by musicians, composers, arrangers and so forth.

A MIDI signal or file does not contain any music. It contains binary data (information) of how a melody is played and when this data reaches a synthesiser, the synthesiser will translate the binary data to music, when connected to an amplifier with speakers so that the sound becomes audible.
