The MPEG is a working group of the International Organization for Standardization (ISO). In order to join the MPEG, a member must be approved by an appropriate ISO member organization from the member’s country – a “National Standards Body”. For example, in the United States, the American National Standards Institute (ANSI) is the National Standards Body that would have to recommend that a member joins the MPEG working group. Membership in the MPEG is not a simple process. Only the most well-qualified organizations and media technology professionals are able to join the MPEG and participate in MPEG meetings.
