White Paper V800-Vodafone V802SE
25 August 2004
Depending on their content and purpose, Win-
dows Media files use a variety of file name
extensions, such as: .wma, .wme, .wms, .wmv,
.wmx, .wmz, or .wvx.
•SMAF
Synthetic music Mobile Application Format
SMAF is a multimedia data format specified by
Yamaha that defines multimedia content that
can be played back on hand-held portable
devices, such as mobile phones and PDAs. The
most common application of SMAF is the cre-
ation of ringtones for mobile phones, although
the specification also supports display of text
and graphics. Therefore the format has potential
for creation of mobile multimedia content. Since
the SMAF files are rather small, about two-thirds
the size of an equivalent MIDI file, device mem-
ory sizes can be kept small, the required disk
capacity for relay servers is reduced, and the
load on networks is lightened.
The extension of a SMAF file is .mmf.
Songs may be stored in the internal phone memory
as well as on the Memory Stick. The folder system
enables the user to organize songs into groups and
create simple playlists of MP3 songs. It also allows
songs to be moved between internal memory and
the Memory Stick.
Songs may be collected in numerous ways, includ-
ing Internet download, file transfer from the PC
and, of course, via the Memory Stick.
The media player is intelligently aware of other
applications in the V800-Vodafone V802SE:
• Playback is paused when a telephone call is
made or received.
• Playback is paused if the user starts another
application which requires the audio channels to
be dedicated to it.
• Playback of MP3 files continues if the user
switches to another application or closes the
phone, providing music whilst using other appli-
cations such as the phonebook or calendar, or
playing games.
Polyphonic ringtones
Background
The word “polyphony” means producing several
tones at the same time. Almost all music that we
listen to consists of polyphonic melodies.
Early Ericsson mobile phones supported a proprie-
tary non-polyphonic format called eMelody. Due to
the musical limitations of eMelody, and the popu-
larity of creating, sending and downloading ring
melodies, Ericsson and Sony Ericsson, together
with other manufacturers, created the more
advanced but non-polyphonic sound format - iMel-
ody.
The introduction of the MIDI format revolutionized
sound quality. MIDI files are small, and perfect for
mobile devices, which have limited storage capac-
ity.
MIDI is a specification for a communications proto-
col principally used to control electronic musical
instruments. MIDI is today a well known standard
used by many musicians, composers and arrang-
ers.
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 synthesizer,
the synthesizer will translate the binary data to
music, when connected to an amplifier with speak-
ers so that the sound becomes audible.

SP-MIDI
SP-MIDI stands for Scalable Polyphony MIDI. SP-
MIDI is based on the MIDI format and adapted for
mobile phones and other portable products. The
objective is to secure interoperability between
products with different sound capabilities.
Initial recommendations for using SP-MIDI in 3GPP
applications are discussed in a separate docu-
ment, Scalable Polyphony MIDI Device 5-24 Note
Profile for 3GPP.
Video clips
The video recorder supports QCIF and sub-QCIF.
The media player supports download and playback
of MPEG-4 and H.263 formats for viewing video
clips in the V800-Vodafone V802SE.
