About the 3GP format for V cast phones from
Verizon:
3G stands for third generation, a generic wireless
industry term for high-speed mobile data delivery over cellular
networks. 3G networks allow users to send and receive bandwidth-intensive
information such as video, video conferencing, high quality audio
and web data on-demand, virtually anytime and anyplace.
3GP is a multimedia container format defined
by 3GPP for use on 3G mobile phones. It is a simplified version
of MPEG-4 Part 14 (MP4). 3GP files have the filename extension .3gp
or .3g2.
3GP stores video streams as MPEG-4 or H.263, and
audio streams as AMR-NB or AAC-LC formats. 3GP files are always
big-endian. 3GP also describes image sizes and bandwidth, so content
is correctly sized for mobile display screens.
QuickTime and 3G
The QuickTime family of standards-based products provides the industry’s
most versatile, cost-effective solution for the creation, delivery
and playback of mobile multimedia over 3G networks. When deployed
on a high-speed mobile network, QuickTime brings to life exciting
new mobile services that will entertain and inform subscribers and
generate new revenue streams for mobile operators and content providers.
Combined with Apple’s wide range of professional and consumer
hardware and software products, QuickTime provides a complete,
end to end solution for key 3G service offerings such as video
messaging and multimedia publishing.
3GP files are viewable on a PC using QuickTime or
RealPlayer, but not windows media player.
MPEG-4 Part 14, formally, ISO/IEC 14496-14:2003,
is a multimedia container format standard specified as a part of
MPEG-4. It is most-commonly used to store digital audio and digital
video streams, especially those defined by MPEG, but also can be
used to store other data such as subtitles and still images. Like
most modern container formats, MPEG-4 Part 14 allows streaming over
the Internet. The official filename extension for MPEG-4 Part 14
files is .mp4, thus the container format is often refered to simply
as MP4.
