What does MPEG stand for?
The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics and genomic data, and transmission and file formats for various applications.
What is the purpose of MPEG-7?
The goal of the MPEG-7 standard, formally called the "Multimedia Content Description Interface", is to provide a rich set of standardized tools to describe multimedia content.
What do you know about MPEG-7?

MPEG achieves its high compression rate by storing only the changes from one frame to another, instead of each entire frame.

What is the major motivation behind the development of MPEG-7?
Motivation for developing the MPEG-7 standard is driven by the clear trends in technology, market, and user needs. Proliferation of tools for audio-visual content creation, digitization, and distribution has brought about an environment in which a large amount of audiovisual content is available.
What are the major differences from MPEG-1 MPEG-4 MPEG 7?
MPEG7 was released in 2002 and is a Multimedia content description standard. It is different that the previous formats, as unlike MPEG-1, MPEG-2 and MPEG-4, it does not deal with coding of moving pictures and audio. In fact, MPEG7 allows the embedding of metadata information into audio and video files.
Is MPEG video?
An MPEG file is a video file that uses a digital video format standardized by the Moving Picture Experts Group (MPEG). It contains video and audio that are compressed using MPEG-1 or MPEG-2 compression. MPEG files are typically used to share videos over the Internet.
