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.
