![]() Therefore, what’s true for audio is certainly true for the MPEG video standards: Today’s media world would look completely different without MPEG codecs. For example, the most important video codec these days, MPEG-4 AVC/H.264, was developed and standardized in MPEG. However, there are many more versions, such as the latest audio standards in MPEG-D or http adaptive streaming in MPEG-DASH.4 A very prominent part of MPEG is, of course, video coding. The most prominent examples of MPEG standards are MPEG-1, MPEG-2, and MPEG-4. At the end of the development and standardization process, a new ISO standard is published and made available for download on the ISO homepage. The group, which meets four times a year, reviews technical submissions and assigns work to members. Unlike other standardization organizations, the development work of new standards does take place during MPEG meetings. 1 The formal name of the group is ISO/IEC JTC 17SC 29/WG 11. Today, more than 350 experts from more than 200 companies and organizations from about 20 countries gather at MPEG meetings. The goal of the “ Moving Picture Experts Group” was to develop standards for coded representation of moving pictures and audio. MPEG audio and video coding started in January 1998 upon the foundation of MPEG as a working group of the International Organization for Standardization, or ISO. Each MPEG audio codec has changed or will change the ways media is consumed. Since then, Fraunhofer IIS and other contributors in ISO-MPEG have developed and standardized several more audio codecs. The first and still most prominent MPEG audio codec is mp3, which first appeared on the market in 1998. Audio codecs are one of the fundamental building blocks of modern media systems.
