MPEG-Four absorbs numerous of the features of MPEG-1 and MPEG-2 and other related standards, adding newly features like (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video & VRML (Virtual Reality Modeling Language) objects), trend lines for externally-specified Digital Rights Management and various types of interactivity.

Virtually all of the features involved inside MPEG-Four come left to human developers to decide whether to implement them. This means that there are probably there is no complete implementations of the entire MPEG-Four placed of standards. To treat by having this, a standard includes a conception of "profiles" & "levels", permitting the specific placed of capabilities to exist as defined within the manner appropriate for the subset of applications.

MPEG-4 Parts
MPEG-Four consists of many standards—termed "parts"—including a ensuing:

Section One (ISO/IEC 14496-One): Systems: Describes synchronization & multiplexing of videos & audio. Part 2 (ISO/IEC 14496-2): Visual: The compression codec for visual information (cd, however textures, synthetic images, etc.). One of a numerous "profiles" inside A share Two is the Advanced Elementary Profile (ASP). Part 3 (ISO/IEC 14496-3): Audio: The placed of compression codecs for perceptual neglect of audio signals, including a few variations of Advanced Audio (AAC) Disregard likewise when more audio/speech coding information. A portion Four (ISO/IEC 14496-Four): Conformity: Describes procedures for touching conformity to more area of the standard. A portion Five (ISO/IEC 14496-Five): Information Package: Will bring software for demonstrating and clarifying a more area of the standard. A portion Sextet (ISO/IEC 14496-6): Delivery Multimedia Integration Framework (DMIF). Section 7 (ISO/IEC 14496-7): Optimized Information Programs: Will bring examples of training produce improved implementations (e.g., within relation to A share Five). A portion 8 (ISO/IEC 14496-8): Carriage in IP networks: Specifies the method to carry MPEG-Four content in IP networks. A share 9 (ISO/IEC 14496-9): Information Devices: Will bring devices designs for demonstrating training implement a more area of the standard. Part 10 (ISO/IEC 14496-10): Advanced cd Coding: The codec for video signals which is as well known as AVC & is technically monovular to the ITU-T H.264 standard. Part 11 (ISO/IEC 14496-11): Scene description and Application engine, likewise known as BIFS, may be utilized for even 3D content or subtitles. Section 12 (ISO/IEC 14496-12): ISO Base MediThe File Format: A file format for storing media content. A share Thirteen (ISO/IEC 14496-13): Intellectual Property Management & Protection (IPMP) Extensions. Part 14 (ISO/IEC 14496-1Four): MPEG-4 File Format: A intended container file format for MPEG-4 content, which is according to A share 12. A share 15 (ISO/IEC 14496-15): AVC File Format: For storage of A share 10 videos according to A portion 12. A share 16 (ISO/IEC 14496-16): Animation Framework eXtension (AFX). Part 17 (ISO/IEC 14496-17): Timed Text subtitle format. Section 18 (ISO/IEC 14496-18): Font Compression & Flowing (for OpenType fonts). Section Xix (ISO/IEC 14496-19): Synthesized Texture Stream. A share 20 (ISO/IEC 14496-20): Lightweight Scene Representation (Optical maser) (non however finished - reached "FCD" stage around January 2005). Section 21 (ISO/IEC 14496-21): MPEG-J Graphical Framework eXtension (GFX) (non eventually finished - at "FCD" stage around July 2005, FDIS January 2006). A portion 22 (ISO/IEC 14496-22): Open Font Format Specification (OFFS) according to OpenType (non however finished - reached "CD" stage within July 2005)

Profiles come besides defined inside a single "parts", and then an implementation of the a portion is usually non an implementation of an entire a share.

MPEG-1, MPEG-2, MPEG-7 and MPEG-21 are other suites of MPEG standards.
