The MPEG-4 is a graphics and video compressing algorithm that was based in MPEG-1 and

MPEG-2 standards. The compression method that uses wavelet based files can create smaller

files than jpeg. This allows the transmission of video and images over a narrower bandwidth

and can mix video with text, graphics, 2D and 3D animation layers.

The MPEG-7, also called MCDI (Multimedia Content Description Interface), provides a tool set

for completely describing multimedia content. It is designed to be generic and not targeted to a

specific application.

The MPEG-21 includes the Rights Expression Language (REL) and the Rights Data Dictionary

(RDD). It is a standard that defines the description of content and processes for accessing,

searching, storing and protecting the copyrights of content.

The MPEG-1 and MPEG-2 formats are the ones that hold the most significant role in the video

history and are an integral part in digital video broadcasting. Let’s inspect them more carefully.
