.mpg is one of file extension for MPEG-1 files.
MPEG-1 is a group of Audio and Video coding and compression standards agreed upon by Moving Picture Experts Group (MPEG).
MPEG1 includes compression codecs for non-interlaced video signals and
for perceptual coding of audio signals.
The standard defines 3 layers, or levels of complexity, of MPEG audio coding:
- MPEG-1 Part 3 Layer 1, or MP1;
- MPEG-1 Part 3 Layer 2, or MP2;
- MPEG-1 Part 3 Layer 3, or MP3.
While MPEG1 applications are often low resolution and low bitrate, this standard allows resolution less than 4095×4095.
Now MPEG1 is the most compatible format in the MPEG family. It is used in almost all computers and VCD/DVD players.
MP3, or MPEG-1 Audio Layer 3 is a digital audio encoding, lossy compression format, and algorithm, designed to reduce the amount of data required for representing audio, but to most listeners sound like original uncompressed audio.
MP3 is an audio-specific compression format which provides representation of pulse-code modulation-encoded audio in less space than straightforward methods. It uses psychoacoustic models to discard components less audible to human hearing, and records the remaining information in an efficient manner. Similar principles are used by JPEG, a lossy image compression format.
MP3 has considerably superseded MP2 for PC and Internet applications.
Each MP3 file is made up of multiple MP3 frames which consist of the MP3 header and the MP3 data. These frames are independent items: it is possible to cut them from a file and an MP3 player would be able to play it.
