MPEG-2 -

encode audio and video for broadcast signals, including digital satellite and Cable TV. MPEG-2, with
some modifications, is also the coding format used by standard commercial DVD movies.
MPEG-4 -
MPEG-4 is a group of audio and video coding standards and related technology. The primary uses for
the MPEG-4 standard are web (streaming media) and CD distribution, conversational (videophone), and
broadcast television.
Most of the features included in MPEG-4 are left to individual developers to decide whether to implement
them or not. 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.
