Om 3G2 Format
3G2 is a multimedia format developed and designed by the 3rd Generation Partnership Project 2 for transmission of multimedia files over the internet, and for use by mobile phone systems. The 3rd Generation Partnership Project 2, or 3GPP2, is a cooperation between various telecommunications associations to make globally applicable third generation (3G) mobile phone system specifications. The 3G2 file format can store the same video streams and most of the audio streams used in the 3GP file format. In addition, 3G2 stores audio streams as EVRC, EVRC-B, EVRC-WB, 13K (QCELP), SMV or VMR-WB, which was specified by 3GPP2 for use in ISO base media file format. The 3G2 specification also defined some enhancements to 3GPP Timed Text.
3GP film kan ses på Linux, Mac og Windows-platforme med MPlayer og VLC media player. Programs such as Media Player Classic, K-Multimedia Player, Totem, RealPlayer, QuickTime, and GOM Player can also be used. 3GP files can be encoded and decoded with open source software Ffmpeg. Most 3G capable mobile phones support the playback and recording of video in 3GP format (memory, maximum filesize for playback and recording, and resolution limits exist and vary). Some newer/higher-end phones without 3G capabilities may also playback and record in this format (again, with said limitations). Audio imported from CD onto a PlayStation 3 when it is set to encode to the MPEG-4 AAC codec will copy onto USB devices in the 3GP format. The Nintendo DSi supports .3gp on an SD card.
