JPEG 2000 Digital Cinema Successes and Proposed Standardization of JPEG XR
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 (www.dcimovies.com) 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.
JPEG Systems and JPEG XR
A new work item was proposed at the meeting to assemble an architecture for imaging called JPEG Systems. This is intended to provide harmonization and integration between a wide range of existing and new image coding schemes, in order to enable the design and delivery of the widest range of imaging applications, across many platforms and technologies. In order to achieve these goals, the first two parts of the proposed Standard, under the generic banner of "JPEG Systems" are intended to be:
- A Technical Report discussing use cases and technical issues and solutions which should be met by the range of Standards and profiles defined in JPEG Systems
- A proposed new Standard designed explicitly for the next generation of digital cameras, based extensively on the technology introduced by Microsoft in its Windows Media Format proposals, at present known as HD Photo.
One important aspect regarding the standardization of HD Photo is Microsoft's commitment to make its patents that are required to implement the specification available without charge. Microsoft's royalty free commitment will help the JPEG committee foster widespread adoption of the specification and help ensure that it can be implemented by the widest possible audience. The JPEG committee hopes and encourages all participants in its meetings to consider this royalty free approach when offering patented technology as a candidate for standardization.
The JPEG committee developed the baseline JPEG Standard (ISO/IEC 10918-1 | ITU-T T.81) nearly 20 years ago, and this has been one of the most successful international standards ever produced and the dominant standard for imagery on the Internet, and in digital cameras. The JPEG committee has also been pleased to see the recent market success of JPEG 2000 (ISO/IEC 15444) in many areas, especially digital cinema, Geographic Information Systems (GIS) including mapping, medical imaging, surveillance and identification, and the archiving of cultural heritage and other photographic materials. The JPEG committee plans to continue to support the digital imaging market through the development of the new JPEG Systems series, intended to enable the rapid integration of existing imaging devices and services with new encoding technology and delivery methods. As an example, the work on the JPEG 2000 series of standard parts has many applications at a more generic level, extending well beyond the scope of the JPEG 2000 core coding standard (ISO/IEC 15444-1 | ITU-T T.800). JPEG 2000 Part 2 (Extensions) provides extension features beyond the core coding system. JPEG 2000 Part 3 (Motion JPEG 2000) extends the Standard into coding of sequence of high quality images. JPEG 2000 Part 6 (JPM) already recognizes the benefits of mixing a set of different compression techniques to achieve maximum effective compression quality. JPEG 2000 Part 8 (JPSEC) is applicable to the protection and encryption of a wide variety of photographic materials. JPEG 2000 Part 9 (JPIP) enables the delivery of large images over wide area networks efficiently using an interactive client/server model. JPEG 2000 Part 10 (JP3D) extends the uses of the Standard into 3D volumetric imaging. JPEG 2000 Part 11 (JPWL) provides methods to achieve reliable image transfer over high error rate environments, such as wireless networks. All these technologies can be used with relatively minor changes or new profiles to provide these functionalities linked to a wider range of coding and metadata standards, all within the scope of the proposed new JPEG Systems.
"JPEG is proving its vitality by integrating new technologies like the proposed new work item JPEG XR into the range of existing JPEG family of standards (JPEG 2000 included) and continuing to provide further options and solutions for modern networked imaging through the proposed new work item, JPEG Systems", said Dr. Daniel Lee the convener of JPEG, and General Manager of the eBay China Development Center.
The JPEG committee intends to invite participation by companies from all sectors of the consumer photography industry, including camera manufacturers; producers of silicon, sensors and optics for cameras; photography ISVs, cell phone manufacturers; kiosk and service bureau equipment makers and printer manufacturers. We encourage JPEG members among those companies to actively participate at the 43rd WG1 Kobe, Japan meeting, 12-16 November, 2007, which will be hosted by the Japanese National Body.
The following presentation was given at the meeting.
- "Stereoscopic coding for digital cinema", Dr. Chaker Larabi, University of Poitiers, France.
