3GP Video Format


3GP is a new multimedia container format which is defined as Third Generation Partnership Project (3GPP). This format is used for 3G UMTS multimedia services. It is used in 3G mobile phones but some 2G phones also support 3GP file format. The Technical Specifications for 3Gp are found in ETSI 3GPP technical specification. 3GP is required for IP multimedia subsystem (IMS), Multimedia Messaging Service (MMS), Multimedia broadcast/multicast services (MBMS) and transparent end to end packet streaming services (PSS).It is a third generation video standard that incorporates mp3,mp4,3gpp and 3gp.
3GP stores video streams in MPEG-4 or H 263 format while audio streams are stored AMR-NB or AAC-LC format. 3GP defines the image sizes and bandwidth requirements as a result the content fits the small mobile screen efficiently. Unlike the MP3 format, 3GP format includes both video and audio streams. Thus both video and audio currents are stored in a single file for this format.
The 3GP format is actually a multimedia format. The extension .3gp clearly shows that this technology is mainly incorporated in 3rd generation mobile phones. It is based on ISO base media file format. This format was defined to minimize the storage and bandwidth requirements so that mobile phones can store and download these files. A 3GP always follows the big-endian format so that the most significant byte is stored and transferred first. The 3GP format is mainly intended to use for mobile phones and devices capable of handling multimedia. Most of the mobile phone records and then play back the video using this 3GP format. A specific player is required in order to watch you mobile made 3GP videos on the PC.
The basis for 3GP file format is MPEG-4 part 12 of ISO.Some older versions didn’t support all the capabilities defined in MPEG-4 part 12 but new versions fully support MPEG-4 part 12. This format is closely related to MPEG-4 part 14 (MP4) format because MPEG-4 part 14 is also based on MPEG-4 part 12. The file extension for 3GP files is .3gp.3GP files can be viewed on PC using software like QuickTime or real player etc. In 3GP file format various things like audio, video and bit rate information is stored in a single file. Due to the compressed nature of 3GP format the size of 3GP file is very small as it is to be stored on a mobile or similar device. As stated earlier, the file with extension ‘.3gp’ stores the video content in the Mp4 format and the audio data in AMR format.
