3GP video format in one of an overview of 3G streaming video encoding formats, enabling users to send large amounts of data to a mobile telephone network, and thus a clear transfer large files, such as audio, video and data network cell phone.
3GP is a simplified version of the MP4 format, reducing storage space and lower bandwidth requirements, so that mobile phones with limited storage space can be used.
3GP is the 3GPP (3rd Generation Partnership Project), a collaboration with a group of telecommunications partners. The Group\'s objective is to maintain and approved by the Global Telecommunication System, based on GSM network and wireless access technology. The organization aims to establish a global mobile networks, users can access the mobile computing anywhere in the world. Their goal is to build a core network, providing global services, mobile phone users via the Internet. It includes many well-known communications provider, such as Apple, Lucent Technologies, Microsoft, IBM, Toshiba, Nokia, and many others.
3GP is a 3G streaming video encoding formats, mainly to cope with the high-speed 3G networks, developed, and it is a kind of mobile phone video format. 3GP is the new standard format for mobile devices, applications in the mobile phone, PSP and other mobile devices, the advantage is that the file size small, mobile and strong, suitable for mobile devices, disadvantage is that the compatibility in the PC, the poor little support software, and the playback quality poor , frame rate is low, compared with a lot of difference between AVI and other formats.
3GP allows users to send large amounts of data moved to the mobile phone network, and thus a clear transfer large files, such as audio, video and data network cell phone. These documents involve a lot of bandwidth, 3GP format, these files can be from almost anywhere. Many modern mobile phones 3GP technology. Most of the 3GP mobile devices equipped with video recording and playback allows users to use mobile phones. These films can also be seen as a computer at home, the converted files to the appropriate format or install the appropriate file viewer. These features allow users to create and record video, while on the road, and then view and modify their privacy, their home. 3GP is a simplified version of the MP4 format, reducing storage space and lower bandwidth requirements, so that mobile phones with limited storage space can be used. 3GP stores multiple types of video files (MPEG-4 Part 2, H.263-based devices, MPEG-410 section), as well as a variety of audio file formats (AMR technology, laptop, support AAC-LC, AMR-WB, and AMR-WB +). 3GP file transfer always occurs in a particular order - the largest and most significant bytes of information is always transferred first.
Part of 3GP video files can be MPEG-4Part2, H.263 or MPEG-4Part10 (AVC/H.264) and other formats to store the sound part of the supports AMR-NB, AMR-WB, AMR-WB +, AAC -LC or HE-AAC to as the voice encoding. 3GP files at present, there are two different criteria:
3GPP (for GSM mobile phones, with the extension .3 gp)
3GPP2 (for CDMA mobile phones, with the extension .3 g2)
The two formats are adopting video MPEG-4 and H.263, and AAC or AMR audio standard is applied. About 3gp-3GPP and 3GPP2
1,3 gpp
3gpp is for GSM phones, with the extension .3 gp. 3rd Generation Partnership Project (3rdGenerationPartnershipProject, ie 3GPP) is an established in December 1998 of the standardization bodies. Its membership currently includes Europe, ETSI, Japan, ARIB and TTC, China, CCSA, South Korea\'s TTA and North America ATIS.
3GPP goal is to ITU\'s IMT-2000 within the scope of the development and the achievement of global (third generation) mobile phone system specification. Its commitment to GSM to UMTS (WCDMA) evolution, although the GSM to WCDMA air interface vary greatly, but its GPRS core network using a framework, it continues to maintain continuity.
2,3 GPP2
3GPP2 is for CDMA phones, with the extension .3 g2. 3rd Generation Partnership Project 2 (3rdGenerationPartnershipProject2, or 3GPP2) was established in December 1998, comprises: TIA (North America), CCSA (China), ARIB / TTC (Japan) and TTA (South Korea).
3GPP2 committed to the ITU\'s IMT-2000 plan (3G) mobile phone system specification in the global development, in fact it is the CDMAOne from 2G, or IS-95 developed from the CDMA2000 standard system of standardization bodies, which are owned a number of key technology patents in the CDMA Qualcomm more support.
3GPP and 3GPP2 there is a certain competition between the two bodies are, 3GPP2 are committed to IS-95 (widely used in North America and South Korea\'s CDMA standard, is compatible with China Unicom CDMA) to 3G transition, and QUALCOMM closer together. Corresponding 3GPP working from GSM to WCDMA (UMTS) transition, so there is a certain competition in the two bodies.
