Brief History Proc. IEEE, April 2012 1st meeting: May 1988 – Hiroshi Yasuda & Leonardo Chiariglione (Ottawa, Canada)
…25 years …
100th meeting: April 2012 --Leonardo Chiariglione (Geneva, Switzerland) Scope (1/2) 12
Area of Work – Development of international standards for compression, decompression, processing, and coded representation of moving pictures, audio, and their combination, in order to satisfy a wide variety of applications Program of Work – Serve as responsible body within ISO/IEC for recommending standards consistent with the Area of Work – Co-operate with other standardization bodies dealing with similar applications (Liaison) – Consider requirements for interworking with other applications defined by other SC29 and other standardization bodies (Global yet orthogonal solutions) Scope (2/2) 13
– Define methods for assessing quality of audio, moving pictures and their combinations – Assess characteristics of implementation technologies realizing audio and moving picture coding – Assess characteristics of digital storage and other delivery media target of the standards developed by WG11 – Develop standards of coding of moving pictures, audio and their combinations taking into account quality of coded media, effective implementation and constraints from delivery media – Propose standards for the coded representation of audio and moving picture information – Propose standards for protocols associated to coded representation of moving pictures and audio The MPEG Process (1/2) 14
