Advanced Audio Coding

AACAAC/AAC+/eAAC+.aac
AAC (Advanced Audio Coding) was standardized as an adjunct to MPEG-2 (as Part 7) before MPEG-4 was issued.
AAC has been standardized by ISO and IEC, as part of the MPEG-2 and MPEG-4 specifications.

Companies promoting MPEG-4 compatibility do not always clearly state which "part" level compatibility they are referring to. The key parts to be aware of are MPEG-4 Part 2 (including Advanced Simple Profile, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by QuickTime 6) and MPEG-4 part 10 (MPEG-4 AVC/H.264 or Advanced Video Coding, used by the x264 encoder, Nero Digital AVC, QuickTime 7, and high-definition video media like Blu-ray Disc).
Nero Digital is a brand name applied to a suite of MPEG-4-compatible video and audio compression codecs developed by Nero AG of Germany and Ateme of France.

Uses of MPEG-4 include compression of AV data for web (streaming media) and CD distribution, voice (telephone, videophone) and broadcast television applications.
The newer MPEG-4 video and audio compression format can deliver high-quality video at 2 Mbit/s, which is at the low end of cable modem and ADSL broadband performance.

MPEG-4 Part 3

AACAAC+ISO/IEC 14496-3
MPEG-4 Part 3 or MPEG-4 Audio (formally ISO/IEC 14496-3) is the third part of the ISO/IEC MPEG-4 international standard developed by Moving Picture Experts Group.

Data compression

compressionvideo compressioncompressed
MPEG-4 is a method of defining compression of audio and visual (AV) digital data.
Although lossless video compression codecs perform at a compression factor of 5 to 12, a typical MPEG-4 lossy compression video has a compression factor between 20 and 200.

MPEG-4 Part 2

MPEG-4 SPMPEG-4 ASPMPEG-4
Companies promoting MPEG-4 compatibility do not always clearly state which "part" level compatibility they are referring to. The key parts to be aware of are MPEG-4 Part 2 (including Advanced Simple Profile, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by QuickTime 6) and MPEG-4 part 10 (MPEG-4 AVC/H.264 or Advanced Video Coding, used by the x264 encoder, Nero Digital AVC, QuickTime 7, and high-definition video media like Blu-ray Disc).
It belongs to the MPEG-4 ISO/IEC standards.

MPEG-7

ISO/IEC 15938
MPEG-1, MPEG-2, MPEG-7 and MPEG-21 are other suites of MPEG standards.
Thus, it is not a standard which deals with the actual encoding of moving pictures and audio, like MPEG-1, MPEG-2 and MPEG-4.

Streaming media

streamingstreamedstreaming video
Uses of MPEG-4 include compression of AV data for web (streaming media) and CD distribution, voice (telephone, videophone) and broadcast television applications.
Encoded audio and video streams are assembled in a container "bitstream" such as MP4, FLV, WebM, ASF or ISMA.

MPEG-4 Part 14

MP4.mp4M4A
The only official filename extension for MPEG-4 Part 14 files is .mp4. MPEG-4 Part 14 (formally ISO/IEC 14496-14:2003) is a standard specified as a part of MPEG-4.

MPEG-2

MPEG2DVDH.262 / MPEG-2 Part 2 video
MPEG-1, MPEG-2, MPEG-7 and MPEG-21 are other suites of MPEG standards. MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally specified Digital Rights Management and various types of interactivity.
Advanced Audio is also defined in Part 3 of the MPEG-4 standard.

MPEG-4 SLS

MPEG-4 SLS
MPEG-4 SLS, or MPEG-4 Scalable to Lossless as per ISO/IEC 14496-3:2005/Amd 3:2006 (Scalable Lossless Coding), is an extension to the MPEG-4 Part 3 (MPEG-4 Audio) standard to allow lossless audio compression scalable to lossy MPEG-4 General Audio coding methods (e.g., variations of AAC).

VRML

Virtual Reality Modeling LanguageVirtual Reality Modelling LanguageWRL
MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally specified Digital Rights Management and various types of interactivity.
The MPEG-4 Interactive Profile (ISO/IEC 14496) was based on VRML (now on X3D), and X3D is largely backward-compatible with it. VRML is also widely used as a file format for interchange of 3D models, particularly from CAD systems.

DMIF, or Delivery Multimedia Integration Framework, is a uniform interface between the application and the transport, that allows the MPEG-4 application developer to stop worrying about that transport.
