What is 3GP?

3GP is the standard used today on the 3G adaptable phones. It is acclaimed in two altered standards; the 3GPP, which is acclimated on GSM-based phones and accept the book extension, .3gp. There is additionally the 3GPP2, which is for CDMA-based phones, and accept the book addendum .3g2. These two standards are MPEG-4 and H.263 based while accepting an AAC and an AMR audio. This multimedia alembic architecture was authentic by the Third Generation Partnership Project (3GPP), a accumulation of telecommunications partners, the ETSI from Europe, ARIB/TTC from Japan, TTA from South Korea, CCSA from China, and ATIS from North America.

The 3GP is a simplistic adaptation of the accepted MP4 (MPEG-4 Part 14) alembic format. Currently this architecture is broadly acclimated for abbreviating the accumulator and bandwidth requirements so that it can be acclimated with adaptable phones. This architecture allows a alive 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 additionally be streamed.

The 3GP technology additionally is developed in a way so that the best important portions of a book are transferred first. During these transfers, descriptions of the files (images) such as its admeasurement and bitrate are additionally transferred. This almost fresh technology is acutely 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 additionally be beheld anon on a adaptable buzz or be transferred to a home computer for watching. Note however, that the 3GP files charge be adapted afore they can be broadly accessed on a home computer. Basically, this allows audience to be able to actualize and almanac on the fly, and the appearance and adapt if all-important on their computer.
