The ITU Standardization Bureau, ITU-T, hosted the 36th Joint Picture Experts Group (JPEG) Meeting, held in Geneva between July 18-22.
The JPEG, formed many years ago jointly by ITU-T Study Group 16 and ISO/IEC JTC1 Study Group 29, is renowned for its JPEG and JPEG-2000 image compression standards.
In ITU-T, Study Group 16 is home to all media coding work, such as the H-Series of Recommendations, and includes work done together with ISO/IEC's JPEG, and JPEG-2000 groups in image compression, as well as work done with MPEG in developing video compression standards such as H.264. ISO/IEC JTC1 SG 29 is the focal point in ISO/IEC JTC1 for image, video and audio compression standards. The meeting surveyed the progress of technologies broached in the previous JPEG meeting, held in Lisbon in March 2005, including image security in JPEG-2000 which is being addressed by JPEG’s JPSEC ad hoc group. The group is developing a standard that will enable protected images to retain JPEG-2000 system features, such as scalability. This new feature within JPEG images will allow international distribution of digital images containing encrypted content, while still retaining the ability to adaptively deliver content for a wide variety of devices with varying display capabilities. The meeting also followed up on JPEG’s Digital Cinema ad hoc group and its advances in developing profiles for JPEG-2000 digital cinema applications. The Digital Cinema Initiatives (DCI) organization has adopted JPEG-2000 for future distribution of digital movies to theatres. JPEG is working closely with the Society of Motion Picture and Television Engineers (SMPTE) to standardize aspects of this future architecture.
The Video and Image Coding and Applications (VICA) workshop, 22-23 July 2005, which followed the ITU-T-hosted JPEG meeting, aimed to build upon the presence of JPEG and ITU-T SG 16 experts (who met July 26 - August 5 this year). The workshop reviewed existing video and image compression standards, their current applications, and future directions in the field.
