Jeju Island, South Korea, March 15, 2002. At its 59th meeting, held from 11-15 March 2002, MPEG issued its 4th Call for Proposal (CfP) in the suite of standards known as MPEG-21. This latest call will accept proposals to be reviewed by experts at its 60th meeting in Fairfax, VA (US) between 6 and 10 May 2002. In this world with a myriad of devices and new ones appearing daily, Digital Item Adaptation is an important technology for content authors and owners, and service providers not just the consumers of MPEG streams. When coupled with the Audio-Visual standards of MPEG-2, or 4 and the metadata standard in MPEG-7, and the other standards being developed in MPEG-21, DIA as it has come to be known, will be another powerful tool in the multimedia industry. Combined with the specifications currently under development to provide a Rights Data Dictionary and a Rights Expression Language, this will provide tools to enable the association of permissions governing the context in which content may be adapted.
MPEG also issued a Call for Proposals on MPEG-7 Systems extensions notably to address additional coding efficiency for MPEG-7 descriptions as well as MPEG-21 Digital Item Declarations. The response to these calls will be reviewed at its 61st meeting in Klagenfurt, Austria from 22 to 26 July 2002.
Details of how to obtain MPEG’s CfP’s are shown below.
Other MPEG news
A preliminary Call for Proposals on Advanced Text and 2D graphics was issued. It will be made final the 60th meeting In May with the expectation of responses due at the 61st meeting in Austria in July.
The MPEG-21 development work on Rights Data Dictionary and Rights Expression Language (RDD/REL) began in earnest following technology selection in Pattaya, TH in December 2001. Use case scenarios leading to core experiments were developed by the RDD/REL experts. These included cases and corresponding rights expressions for video news syndication, music album release, and distribution combining digital items. The complexity and importance of this work was recognized as other elements of MPEG standards and development work began to be used in these use case scenarios, such as MPEG-7 descriptors and the MPEG-4 XMT technology.
Even MPEG-2 is getting into the act. An amendment to update the Conditional Access technology specified in MPEG-2 Systems (ISO/IEC 13818-1:2000) was initiated in Jeju Island. Known by the name used in MPEG-4 and MPEG-21, IPMP (INtellectual Property Management and Protection) for MPEG-2 is the first major upgrade of the standard in this area since MPEG-2 was finalized in 1994. "It is exciting to see MPEG-2 take on this new and important technology" said Dr. Chiariglione, Convenor of WG 11.
MPEG-4 Video reference software will become publicly available at a single Web site (http://megaera.ee.nctu.edu.tw/mpeg/). This will include the reference software from part 5 of MPEG-4, as well as an optimized package of encoder and decoder for MPEG-4 Visual Simple Profile.
MPEG-4 audio technology improvements continue as well. "Parametric Coding for High Quality Audio" was available following the Pattaya meeting and now "Backward Compatible Bandwidth Extension for General Audio Coding" is available. Both methods are expected to provide an additional bitrate saving of at least 25% over known coding methods.
