The "Moving Picture Experts Group" (MPEG) is a working group of experts that was formed by ISO and IEC to set standards for audio and video compression and transmission.
-The MPEG compression methodology is considered "asymmetric" as the encoder is more complex than the decoder. The encoder needs to be algorithmic or adaptive whereas the decoder is 'dumb' and carries out fixed actions
