The International Organization for Standardization (ISO) is a network of the national standards institutes of 156 countries, on the basis of one member per country, with a central office in Geneva, Switzerland, that coordinates the system. The national standards institutes are also "only" networks of other national institutes that research and develop in special areas, e.g. the Frauenhofer Institute (who originated MPEG1 Layer 3 (MP3)) is part of Deutsches Institut für Normung (German Instiute for Standardization - DIN), wich is part of ISO.

Only a small fraction of all ISO standards are multimedia-related. Other ISO standards define such things as papersize, keyboard layouts, timestamp formats, and many more. For electronics, the ISO works together with the International Engineering Consortium (IEC), which together form the Joint Technical Committee (JTC) wich is split into subcommittees which research special areas. For multimedia, the subcommittees (SC) SC23 "Digital Storage Media for information interchange", SC24 "Computer graphics, image processing and environmental data representation" and SC29 "Coding of audio, picture, multimedia and hypermedia information" are important.

The following standards are multimedia-related:
