.MPG File Name Extension - MPEG Files

✍: Guest


mpg is the file name extension for files that stores audio and video data together using the MPEG (Moving Picture Experts Group) formats developed by ISO/IEC.

There are several MPEG formats available today:
* MPEG-1: Initial video and audio compression standard. Later used as the standard for Video CD, and includes the popular Layer 3 (MP3) audio compression format.
* MPEG-2: Transport, video and audio standards for broadcast-quality television.
* MPEG-3: Originally designed for HDTV, but abandoned when it was realized that MPEG-2 (with extensions) was sufficient for HDTV.
* MPEG-4: Expands MPEG-1 to support video/audio "objects", 3D content, low bitrate encoding and support for Digital Rights Management.
* MPEG-21: Defines an open framework for multimedia applications.
