What is MP4?
MPEG-4 Part 14, formally ISO/IEC 14496-14:2003, is a multimedia container format
standard specified as a part of MPEG-4. It is most commonly used to store digital
audio and digital video streams, especially those defined by MPEG, but can also
be used to store other data such as subtitles and still images. Like most modern
container formats, MPEG-4 Part 14 allows streaming over the Internet. The official
filename extension for MPEG-4 Part 14 files is .mp4, thus the container format
is often referred to simply as MP4.
MPEG-4 is a patented collection of methods defining compression of audio and
visual (AV) digital data. It was introduced in late 1998 and designated a standard
for a group of audio and video coding formats and related technology agreed upon
by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC1/SC29/WG11) under
the formal standard ISO/IEC 14496 - Coding of audio-visual objects. Uses
of MPEG-4 include compression of AV data for web (streaming media) and CD distribution,
voice (telephone, videophone) and broadcast television applications.
MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related
standards, adding new features such as (extended) VRML support for 3D rendering,
object-oriented composite files (including audio, video and VRML objects), support
for externally-specified Digital Rights Management and various types of interactivity.
AAC (Advanced Audio Coding) was standardized as an adjunct to MPEG-2 (as Part
7) before MPEG-4 was issued.
MPEG-4 is still a developing standard and is divided into a number of parts.
Companies promoting MPEG-4 compatibility do not always clearly state which "part"
level compatibility they are referring to. The key parts to be aware of are MPEG-4
part 2 (including Advanced Simple Profile, used by codecs such as DivX, Xvid,
Nero Digital and 3ivx and by Quicktime 6) and MPEG-4 part 10 (MPEG-4 AVC/H.264
or Advanced Video Coding, used by the x264 encoder, by Nero Digital AVC, by Quicktime
7, and by high-definition video media like Blu-ray Disc).
What is MPA?
MPA is compressed audio file using MPEG Layer I, II or III compression. There
are three "layers" in the MPEG-1 Audio specification. In MPEG Audio
Layer-1, a simple 32-subband audio compressor using a floating point representation
for subband samples. Resolution and scale factor are stored for groups of 12 subsamples.
MP1 is only used for Philips DCC Digital Compact cassette with data rates of 384
kbps. Both MPEG-1 and MPEG-2 files use MPEG-1 Audio Layer-2. MPEG-1 Audio Layer-3
becomes the widely popular MP3.
