Subject: MPEG-7 Information From: Adam Taro Lindsay <alindsay(at)media.mit.edu> Date: Mon, 9 Nov 1998 12:17:26 +0100Hi, all. I'd like to bring to your attention a technology development which may be relevant to the work of many of us on the list. MPEG, the Moving Pictures Expert Group, a working group of ISO, has started a new work item officially called the "Multimedia Content Description Interface." It will exist as a means of describing audio-visual material in a standard way for the purposes of search and retrieval, filtering, and other more specialized uses of meta-data. I personally see it (in part) as a codification of the current state of the art in audio analysis. *Representation* is central to the standard. All else, such as analysis methods and database retrieval, is secondary (but still important). As obvious features from the audio world, I expect to see such things as query-by-humming, speech descriptions, and temporal and spectral feature representations. There is obviously room for much more, and the standard is being written to be extensible. However, the standard requires participation to go forward, and the audio side has been slow to get started. Therefore, I'd like to open it up to this community. The MPEG-7 Call for Proposals was issued last month, and there is a pre-registration deadline on December 1, 1998. For information, the place to get started is: http://www.cselt.it/mpeg/public/mpeg-7_cfp.htm There is also a section on MPEG-7 in the MPEG Audio FAQ: http://www.tnt.uni-hannover.de/project/mpeg/audio/faq/#59 I also administer an "ad hoc group" mailing list for MPEG-7 Audio concerns. to subscribe: Send an email with "subscribe" in the subject to: mpeg-7-aud-request(at)meta-labs.com Also see: http://www.meta-labs.com/mpeg-7-aud/ There is a semi-official MPEG-7 web site at: http://www.darmstadt.gmd.de/mobile/MPEG7/ Please don't hesitate to contact me if you have any questions about MPEG-7. I do hope that this information is worth something to someone out there. Adam -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Adam T.
