P800/P802

White Paper, January 2003

Multimedia

The P800 has extensive multimedia capability in many applications. This section explains the different standards supported and provides a summary of capability by application.

Audio Formats

The table below explains the various audio formats supported by the P800, together with indicative file sizes for 60 seconds of playback.

Format	Example	Description
	File Size
AAC		Advanced Audio Coding. This is one of the audio compression formats
		defined within the MPEG-2 standard. Compared to MP3 it has more
		advanced features and is more efficient. AAC is commonly used as the
		audio component of an MPEG-4 video file or stream. The P800 Video
		Player can play AAC format audio which is encoded into an MPEG-4 file or
		stream. Such audio-only content is not common.
AMR	94kB	Adaptive Multi Rate. AMR is a speech compression format that is highly
	(12.2	optimised for the mobile environment, requiring as little as 4.75kbps
	kbps)	bandwidth. AMR is used to convey voice recordings in MMS, when the
		P800 records at a rate of 12.2kbps. Sample rate is 8kHz and processing is
		done on 20ms frames.
AU	1.35MB	Similar to WAV, this is an audio format commonly used in the Macintosh,
	(22.05	unix and java worlds. It is not commonly used for content on mobile
	kHz)	devices.
iMel-	6kB	A format commonly used for monophonic ringtones.
ody
MIDI	20kB	MIDI means Musical Instrument Digital Interface. MIDI specifies a format
		which describes music in a binary format which may then be stored as a
		file. Unlike the other formats, MIDI is not a recording of music but a
		description which enables a local synthesizer to play the music from the
		instructions included in the MIDI file. MIDI is ideal for polyphonic ringtones.
		The P800 includes the Beatnik mini-BAETM(Beatnik Audio Engine)
		providing support for General MIDI Level 1.
MP3	960kB	MPEG1 Layer 3 audio compression. MP3 is a very popular format for
	(128kbps)	downloading songs from the internet. It is also increasingly available in
		personal and in-car audio equipment. MP3 files can be created with
		different size/quality compromises.
RMF	72kB	Rich Music FormatTM A file format developed by Beatnik combining the
		compact size of MIDI files with the high quality of sampled sound.
WAV	1.35MB	This is an typically used for short ‘alert’ sounds. The size of files is
	(22.05	determined by sample rate, bits-per-sample and mono/stereo.
