What Does MPEG-4 Part 2 Mean?

MPEG-4 Part 2 is an MPEG standard that is a part of the MPEG-4 standard group with the inclusion of AVC. The compression algorithm used in MPEG-4 Part 2 is much more efficient than MPEG-4, but the only exception is the inability of MPEG-4 Part 2 to provide compression for the AVC format. It offers efficient encoding and video compression compared to any other MPEG-4 compression algorithms.

Techopedia Explains MPEG-4 Part 2

MPEG-4 Part 2 was introduced in 1999. Some of the most well-known compression algorithms that use MPEG-4 Part 2 are DivX and Xvid, which were initially for use on computers, but are now used in standalone DVD players.

The two profiles for this standard are used for compression of various types of pictures. The Simple Profile (SP) is used for muxing of videos sent and received over a #G connection, and hence the quality is compromised to accommodate a smaller video size. The Advanced Simple Profile (ASP) is more commonly used in home videos, gaming, and other such video applications where advanced features of this algorithm are used. The two profiles are generally known simply as MPEG-4 SP or MPEG-4 ASP, respectively.
