MPEG-4 is a standard used primarily to compress audio and visual (AV) digital data. The most common uses for the MPEG-4 standard are web (streaming media) and CD distribution, conversation (videophone), and broadcast television.

Most of the features included in MPEG-4 are left to individual developers to decide whether to implement them. 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.
