What is 3GP2?
3GPP and 3GPP2 are the new worldwide standards for the creation, delivery and
playback of multimedia over 3rd generation, high-speed wireless networks. Defined
by the 3rd Generation Partnership Project and 3rd Generation Partnership Project
2 respectively, these standards seek to provide uniform delivery of rich multimedia
over newly evolved, broadband mobile networks (3rd generation networks) to the
latest multimedia-enabled wireless devices. 3GPP and 3GPP2 are based on the MPEG-4
standard which was derived from Apple's QuickTime. QuickTime 6.5 includes support
for key components of the 3GPP and 3GPP2 specifications.
The 3GP and 3G2 file formats are both structurally based on the ISO base media
file format defined in ISO/IEC 14496-12 - MPEG-4 Part 12, but older versions of
the 3GP file format did not use some of its features. 3GP and 3G2 are a container
formats similar to MPEG-4 Part 14 (MP4), which is also based on MPEG-4 Part 12.
The 3GP and 3G2 file format were designed to decrease storage and bandwidth requirements
in order to accommodate mobile phones.
What is MP3?
MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a digital audio encoding
format using a form of lossy data compression. It is a common audio format for
consumer audio storage, as well as a de facto standard encoding for the transfer
and playback of music on digital audio players. MP3's use of a lossy compression
algorithm is designed to greatly reduce the amount of data required to represent
the audio recording and still sound like a faithful reproduction of the original
uncompressed audio for most listeners, but is not considered high fidelity audio
by audiophiles. An MP3 file that is created using the mid-range bit rate setting
of 128 kbit/s will result in a file that is typically about 1/10th the size of
the CD file created from the original audio source. An MP3 file can also be constructed
at higher or lower bit rates, with higher or lower resulting quality. The compression
works by reducing accuracy of certain parts of sound that are deemed beyond the
auditory resolution ability of most people. This method is commonly referred to
as perceptual coding. It internally provides a representation of sound within
a short term time/frequency analysis window, by using psychoacoustic models to
discard or reduce precision of components less audible to human hearing, and recording
the remaining information in an efficient manner. This is relatively similar to
the principles used by JPEG, an image compression format.
