Uses of MPEG-4 include compression of AV data for web streaming media and CD distribution, voice telephonevideophone and broadcast television applications. MPEG-4 is still an evolving standard and is divided into a number of parts. Companies promoting MPEG-4 compatibility do not always iiso state which “part” level compatibility they are referring to. Most of the features included in MPEG-4 are left to individual developers to decide whether or not to implement.

This means that there are probably no complete implementations of the entire MPEG-4 set of standards. To deal with this, the standard includes the concept of “profiles” and “levels”, allowing a specific set of capabilities to be defined in a manner appropriate for a subset of applications.

Initially, MPEG-4 was aimed primarily at low bit-rate video communications; however, its scope as a multimedia coding standard was later expanded.

MPEG-4 is efficient across a variety of bit-rates ranging from a few kilobits per second to tens of megabits per second. MPEG-4 provides the following functions:. MPEG-4 provides a series of technologies for developers, for various service-providers and for end users:.

MPEG-4 provides a large and rich set of tools for encoding. Subsets of the MPEG-4 tool sets have been provided for use in specific applications. These subsets, called ‘Profiles’, limit the size of the tool set a decoder is required to implement. MPEG-4 consists of several standards—termed “parts”—including the following each part covers a certain aspect of the whole specification:. Profiles are also defined within the individual “parts”, so an implementation of a part is ordinarily not an implementation of an entire part.


The ASP profile in its highest level is suitable for most usual DVD medias and players or for many online video sites, but not for Blu-ray records or online HD video contents.

Information about transport of MPEG-4 content is defined e. A compression format for visual data video, still textures, synthetic images, etc. Provides reference software for demonstrating and clarifying the other parts of the standard. Scene description and application engine. Can be used for rich, interactive content with multiple profiles, including 2D ios 3D versions.

ISO base media file format. A file format for storing time-based media content. It is a general format forming the basis for a number of other more specific file formats e.

It was defined due to the lack of interoperability of different protection mechanisms different DRM systems for protecting and distributing copyrighted digital content such as music or video. It is also known as “MPEG-4 file format version 2”. Systems 41496-1, in which the MPEG-4 file format was previously specified. For storage of Part 10 video. File format is based on Part 12, but also allows storage in other file formats.

MPEG-4 is extended with higher-level synthetic objects for specifying geometry, texture, animation and dedicated compression algorithms. Defines a model for connecting 3D Graphics Compression tools defined in MPEG-4 standards to graphics primitives defined in any other standard or specification. Guidelines are given on constructing tests to verify decoder conformance.
