notes  MPEG-4 Part 2 (or Simple and Advanced Simple Profile) and
 MPEG-4 AVC (or MPEG-4 Part 10 or H.264). The MPEG-4 AVC may be used on HD
DVD and Blue-ray Discs, along with VC-1 and MPEG-2.
In addition, the following standards, while not sequential advances to the video encoding standard
as with MPEG-1 through MPEG-4, are referred to by similar notation:
• MpeG-7 (2002): Multimedia content description interface. (ISO/IEC 15938)
• MpeG-21 (2001): Multimedia framework (MPEG-21). (ISO/IEC 21000) MPEG describes this
standard as a multimedia framework and provides for intellectual property management
and protection.
Moreover, more recently than other standards above, MPEG has started following international
standards; each of the standards holds multiple MPEG technologies for a way of application. (For
example, MPEG-A includes a number of technologies on multimedia application format.)
• MpeG-a (2007): Multimedia application format (MPEG-A). (ISO/IEC 23000) (e.g., Purpose
for multimedia application formats, MPEG music player application format, MPEG photo
player application format and others).
• MpeG-B (2006): MPEG systems technologies. (ISO/IEC 23001) (e.g., Binary MPEG format
for XML, Fragment Request Units, Bit stream Syntax Description Language (BSDL) and
others).
• MpeG-C (2006): MPEG video technologies. (ISO/IEC 23002) (e.g., Accuracy requirements
for implementation of integer-output 8x8 inverse discrete cosine transform and others).
• MpeG-D (2007): MPEG audio technologies. (ISO/IEC 23003) (e.g., MPEG Surround, SAOC-
Spatial Audio Object Coding and USAC-Unified Speech and Audio Coding).
• MpeG-e (2007): Multimedia Middleware. (ISO/IEC 23004) (a.k.a. M3W) (e.g., Architecture,
Multimedia application programming interface (API), Component model and others).
• supplemental media technologies (2008). (iso/ieC 29116) part 1: Media streaming
application format protocols will be revised in MPEG-M Part 4 - MPEG extensible
middleware (MXM) protocols.
• MpeG-v (2011): Media context and control. (ISO/IEC 23005) (a.k.a. Information exchange
with Virtual Worlds) (e.g., Avatar characteristics, Sensor information, Architecture and
others).
• MpeG-M (2010): MPEG extensible Middleware (MXM). (ISO/IEC 23006) (e.g., MXM
architecture and technologies, API, MPEG extensible middleware (MXM) protocols).
• MpeG-U (2010): Rich media user interfaces. (ISO/IEC 23007) (e.g., Widgets).
