3G2 (3GPP2 file format) is a multimedia container format defined by the 3GPP2 for 3G CDMA2000 multimedia services. It is very similar to the 3GP file format but consumes less space & bandwidth, and has some extensions and limitations in comparison to 3GP.
Some containers only support a restricted set of video formats: DMF only supports MPEG-4 Visual ASP with DivX profiles. EVO only supports MPEG-4 AVC, MPEG-1 Video, MPEG-2 Video and VC-1. F4V only supports MPEG-4 AVC, MPEG-4 Visual and H.263. FLV only supports MPEG-4 Visual, VP6, Sorenson Spark and Screen Video.
The 3rd Generation Partnership Project 2 ( 3GPP2) was a collaboration between telecommunications associations to make a globally applicable third generation ( 3G) mobile phone system specification within the scope of the ITU 's IMT-2000 project. In practice, 3GPP2 was the standardization group for CDMA2000, the set of 3G standards based on the ...
The 3rd Generation Partnership Project ( 3GPP) is an umbrella term for a number of standards organizations which develop protocols for mobile telecommunications. Its best known work is the development and maintenance of: [ 1] GSM and related 2G and 2.5G standards, including GPRS and EDGE. UMTS and related 3G standards, including HSPA and HSPA+.
It uses .3gp and .3g2 extensions. These files also store non-MPEG-4 data (H.263, AMR, TX3G). In practice, most (if not all) low end phones and feature phones recorded in this format, as most (if not all) other mobile phones and smartphones record MP4 files using the .mp4 file extension, and some high end phones [which?] can record in .raw.
The ISO base media file format ( ISOBMFF) is a container file format that defines a general structure for files that contain time-based multimedia data such as video and audio. [ 3][ 4] It is standardized in ISO / IEC 14496-12, a.k.a. MPEG-4 Part 12, and was formerly also published as ISO/IEC 15444-12, a.k.a. JPEG 2000 Part 12.
MPEG-2 is used in Digital Video Broadcast and DVDs. The MPEG transport stream, TS, and MPEG program stream, PS, are container formats. MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". [ 1] It describes a combination of lossy video compression and ...
