Format Description
MPEG-4 ISO File Format (.mp4), ISO/IEC
14496-14, including MPEG-4 AAC-LC
and AMR-NB audio. File formats that are specified as a part of the ISO/IEC MPEG-4
international standard. It is used to store media types defined
by the ISO/IEC Moving Picture Experts Group, and can be
used to store other media types as well. It is, typically used to
store data in files, though it will be used in data streams and
possibly in other ways. *.mp4 allows multiplexing of multiple
video and audio streams in one file, variable frame- and bit-
rates, subtitles and still images. It also allows streaming over
the Internet.
3GPP File Format (.3gp), 3GPP TS
26.234 V5.6.0, including MPEG-4 AAC-
LC and AMR-NB audio File formats which are used in mobile phones to store media
(audio/video). This file format is a simpler version of “ISO
14496-1 Media Format”. This format can only carry video
encoded as MPEG-4 or H.263. Audio is stored in AMR-NB or
AAC-LC formats
RealMedia A digital sound and video file format that is the registered
trademark of RealNetworks. This format is typically used to
stream media through the net.
Format Description
BMP
Microsoft
®
Windows Bitmap. A graphics format defined by Microsoft
®
supporting 1, 4, 8 or
18-bit colour depth. No compression, so files can be very large. Used for icons and very
small images.
GIF Graphics Interchange Format. Highly compressed by limiting the colour palette to 16 or 256
colours. GIF is therefore good for icons and diagrams. When a Note is sent as an email
attachment, the GIF format is used.
GIF
(animated)
A GIF animation containing a number of images in a timed and repeating sequence. Some
P990i applications display only the first image in the sequence.
JPEG (.JPG) An image compression format managed by the Joint Photographic Experts Group. The for-
mat supports various degrees of compression, enabling different quality/file-size balances
to be provided in one standard. JPG files support millions of colours and are therefore good
for 'real life' photographs.
MBM Multi Bitmap. This is a Symbian OS format for colour and greyscale bitmap images.
PNG Portable Network Graphics. PNG compresses images with millions of colours so there is no
loss of detail, but has comparatively large file size. It is not commonly used.
WBMP Wireless Bitmap. An image format optimized for small mobile devices. P990i supports Black
and White, 2-bit greyscale and 6-bit colour modes, according to ETSI 3GPP TS 23.040
