The Joint Photographic Experts Group (JPEG) is a working group of ISO/IEC, the International Organization for Standardization / International Electrotechnical Commission, (ISO/IEC JTC1/SC29/WG1) and of the International Telecommunication Union (ITU-T SG16), responsible for the popular JPEG, JBIG, JPEG-LS, and JPEG 2000 family of imaging standards. The WG1 group meets three times a year, in North America, Europe and Asia. The latest meeting was held July 2-6, 2007, at EPFL, in Lausanne, Switzerland, hosted by Swiss National Body with delegates from 14 countries.

The success of JPEG 2000 in Digital Cinema continues to grow as the Digital Cinema Initiatives has recently approved the JPEG 2000 based DCI specification 1.1 for distribution of digital movies to theatres/cinemas worldwide. The strength of Digital Cinema is apparent with nearly 4,000 JPEG 2000 compliant servers deployed and nearly 5,000 systems expected by the end of 2007. The most recent JPEG 2000 digital cinema releases include Transformers from Paramount Pictures and Harry Potter and the Order of the Phoenix from Warner Bros.

The Digital Cinema ad hoc group within the JPEG committee remains very active and successful in seeing their work adopted by the industry. The ad hoc group is currently working on profiles for archiving motion imagery for both cinematic and broadcast content, and has also begun exploring stereoscopic image compression.
