History of Video technology (Nowadays and Future)
2.2 Technical Standardization for Video Coding
The history of video coding technology has been deeply related to international
standardization since the 1980s. Because interoperability is very important for the
widespread utilization of video contents, it is important that coded video contents
should conform to an international standard. In the following, international stan-
dards for video coding focusing on MPEG are surveyed.
2.2.1 International Organizations of Video Coding Standards
Video coding technology has been playing an important role in the progress of
video technology and the spread of video contents and applications. Standardiza-
tion organizations responsible for digital video related technologies and their mu-
tual relationships are shown in Fig. 3.
ISO/IEC and ITU-T are the primary organizations in the world that engage in
the international standardization of video coding. MPEG is one of the working
groups, formally known as ISO/IEC JTC1/SC29/WG11, which belongs to a Joint
committee of ISO (International Standardization Organization), which promulgates
industrial and commercial standards, and IEC (International Electro-technical
Commission) which treats international standards for all electrical, electronic and
related technologies. On the other hand, ITU-T is an international standardization
organization for telecommunications which was formerly called CCITT, and it has
been coordinating many standards in the field of telecommunications.
