3GP is the standard used today on the 3G mobile phones. It is distinguished in two different standards; the 3GPP, which is used on GSM-based phones and have the file extension, .3gp. There is also the 3GPP2, which is for CDMA-based phones, and have the file extension .3g2. These two standards are MPEG-4 and H.263 based while having an AAC and an AMR audio. This multimedia container format was defined by the Third Generation Partnership Project (3GPP), a group of telecommunications partners, the ETSI from Europe, ARIB/TTC from Japan, TTA from South Korea, CCSA from China, and ATIS from North America.
Inside the Technology
The 3GP is a simplistic version of the popular MP4 (MPEG-4 Part 14) container format. Currently this format is widely used for decreasing the storage and bandwidth requirements so that it can be used with mobile phones. This format allows a streaming of videos like MPEG-4 Part 2 and MPEG-4 Part 10 (AVC/H.264). Audio formats like AMR-NB, AMR-WB, AMR-WB+, AAC-LC, and the HE-AAC can also be streamed.
The 3GP technology also is developed in a way so that the most important portions of a file are transferred first. During these transfers, descriptions of the files (images) such as its size and bitrate are also transferred. This relatively new technology is clearly transmitted, although a downside of it is that the files eat up a lot of the bandwidth. As the 3GP is a video and an audio technology, these files can also be viewed directly on a mobile phone or be transferred to a home computer for watching. Note however, that the 3GP files must be converted before they can be widely accessed on a home computer. Basically, this allows clients to be able to create and record on the fly, and the view and edit if necessary on their computer.
