The Moving Picture Experts Group, develops standards for 
digital video and digital audio compression. It operates under 
the auspices of the International Organization for 
Standardization (ISO). MPEG-4 goes far beyond compression 
methods: Instead of treating the data as continuous streams, 
MPEG-4 deals with audio/video objects that can be manipulated 
independently, allowing for interaction with the coded data and 
providing flexibility in editing. MPEG-4 supports a wide range 
of audio and video modes and transmission speeds.
