Description 3g2 was originally developed by the 3rd Generation Partnership Project 2. It is an audio and video format for use on 3G phones. It can also be played on some 2G and 4G phones. It is designed for transmitting multimedia files over the internet and is mainly used for viewing videos on mobile phones. 3G2 is also known as 3GPP2 which is based on the MPEG-4 standard which was derived from Apple's QuickTime. You are probably familiar with it if you have an Iphone. MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio, but can also be used to store other data such as subtitles and still images.

Technical details 3g2 is very much like MPEG-4 Part 14 (MP4) but a much more simplified version of it. It is designed to reduce bandwidth requirements in order to accommodate mobile phones. It is also designed to decrease storage - it stores video streams as MPEG-4 Part 2 or MPEG-4 part 10. It stores audio streams such as AMR-WB, AMR-NB, AMR-WB+, HE-AAC or AAC-LC. The idea is that 3g2 stores and transfers the most significant bytes first. Most kinds of data can be embedded in MPEG-4 Part 14 files through private streams. A separate hint track is used to include streaming information in the file. The registered codecs for MPEG-4 Part 12-based files are published on the website of MP4 Registration authority (mp4ra.org).
