What is 3GP?

Multimedia Format Description

3GP is in fact a multimedia file format. It was defined by 3GPP for use by high-speed wireless networks, or 3G cell phones.

3GPP, or 3rd Generation Partnership Project, is a collaboration of the telecommunication associations European Telecommunications Standards Institute, Association of Radio Industries and Businesses/Telecommunication Technology Committee (Japan), China Communications Standards Associations, Alliance for Telecommunications Industry Solutions (North America), and Telecommunications Technology Association (South Korea). Its purpose is to make globally applicable third generation (3G) mobile phone system specifications within the ITU (International Telecommunication Union) scope. These third generation specifications are based on GSM (Global System for Mobile Communications) specifications.

The 3GP file format, with the file extension ‘.3gp’, stores video as MPEG-4 Part 14 and H.263 files, and audio streams as AAC and AMR audio files. 3GP's are big endian and the content is also correctly sized for mobile display screens as image sizes and bandwidth are also described in the file. The video usually has a resolution of 176 x 144 or 176 x 120, and rarely exceeds 320 x 240 (or 368 x 208 for widescreen).

Most third generation mobile phones support recording and playback of video in 3GP format. Some newer mobile phones which do not have 3G capabilities, can also playback the 3GP format. Video clips recorded in 3GP on mobile phones, may also be transferred onto computers and viewed using Real Networks Real Player, Apple Quick Time Player, and Media Player Classic.
