What is a 3G2 file
The 3G2 file extension is an updated version of the 3GP file that has been used in the past, but is now outdated. The 3rd Generation Partnership Project (and the 3rd GPP – 2 Project) created standards related to how various forms of multi-media are delivered, especially via mobile networks. One of the new standards set was the use of 3G2 in streaming various types of multimedia files over the world wide web. This type of file is most frequently used in cell phones and can be used by any phone that is 3G capable. 3G2 movie files can also be played on most computers, although additional programs may be required.
3G2 resembles the MPEG-4 Part 14 series (cf. MP4), but is less complicated than its MPEG relation. Using this file type reduces bandwidth requirements, which makes it ideal for mobile phones due to the decreased bandwidth needed and the lower requirements for storage space. Video streams use the MPEG-4 Part 2 and MPEG-4 Part 10 standards to reduce file sizes. Audio is stored as AMR-WB, AMR-NB, AMR-WB+, He-AAC, and/or AAC-LC. This is all accomplished by allowing the 3G2 files to store and transfer important bytes, giving priority to significant information. 3G2 files are designed for CDMA-based phones.
Here's a small, but not exhaustive list of programs that can open 3G2 documents:
- Microsoft Media Player Classic
- Apple QuickTime Player
- GOM Player
- Totem
- VideoLAN VLC Media Player
