Inverse Discrete Cosine Transform.
IEEE (Institute of Electrical and Electronics
The Institute of Electrical and Electronics Engineers (IEEE) is the world's
largest technical professional society.
Founded in 1884 by a handful of practitioners
of the new electrical engineering discipline, today's Institute includes
46,000 students within a total membership of nearly 320,000 members who
conduct and participate in its activities in 150 countries. The men and
women of the IEEE are the technical and scientific professionals making
the revolutionary engineering advances which are reshaping our world today.
And today's students are the future of the profession.
The technical objectives of the IEEE focus on
advancing the theory and practice of electrical, electronics and computer
engineering and computer science. To realize these objectives, the IEEE
sponsors nearly 800 Student Branches worldwide, as well as scholarships
and awareness programs, technical conferences, symposia and local meetings;
publishes nearly 25% of the world's technical papers in electrical, electronics
and computer engineering; and provides educational programs to keep its
members' knowledge and expertise state-of-the-art.
Inverse Modified Discrete Cosine Transform.
A method of exploiting stereo irrelevance or redundancy in stereophonic
audio programmes based on retaining at high frequencies only the energy
envelope of the right and left channels.
The International Organization for Standardization, ISO, in Geneva is
the head organization of all national standardization bodies. Together
with the International Electrotechnical Commission, IEC, ISO concentrates
its efforts on harmonizing national standards all over the world. The
results of these activities are published as ISO standards. Among them
are, for instance, the metric system of units, international stationery
sizes, all kinds of bolt nuts, rules for technical drawings, electrical
connectors, security regulations, computer protocols, file formats, bicycle
components, ID cards, programming languages, International Standard Book
Numbers (ISBN). Over 10,000 ISO standards have been published so far and
you surely get in contact with a lot of things each day that conform to
ISO standards you never heard of.
By the way, ISO is not an acronym for the organization
in any language. It's a wordplay based on the English/French initials
and the Greek-derived prefix iso- meaning same.
Within ISO, ISO/IEC Joint Technical Committee
1 (JTC1) deals with information technology.
ITU (International Telecommunication Union)
The ITU is a world-wide organization within which governments and private
sector coordinate the establishment and operation of telecommunication
networks and services; it is responsible for the regulation, standardization,
coordination and development of international telecommunications as well
as the harmonization of national policies.
The ITU goal is to foster and facilitate the global
development of telecommunications for the universal benefit of mankind,
through the rule of law, mutual consent and cooperative action.
