Signal Processing
and the
Multimedia Information Infrastructure




This page provides URL's of Web sites relating to signal processing and the international information infrastructure, where "information" means multimedia signals: speech, audio, images, video, graphics, text, and others, and where "infrastructure" refers primarily to the internet and intranets and the transmission and storage channels that connect to them.

The list is unfortunately out of date and in desperate need of revision. I hope to do this during fall 2002.

The list began with a 1994 NSF Panel on Signal Processing and the National Information Infrastructure. A wealth of information on the NII can be found at The Digital Information Infrastructure Guide The list was further developed as a supplement to conference presentations at the International Conference on Telecommunications (ICT) in Istanbul, Turkey, 15 April 1996, and subsequently for the First International Conference on Information, Communications & Signal Processing (ICICS), 9-12 September 1997 in Singapore. The emphasis and title have evolved to reflect the lack of boundaries to the information infrastructure and importance of diverse signals or "multimedia" as well as on individual signal types.

The slides for the Singapore talk provide a guided tour through some of the links of this page. (Also available are the slides used for my day long tutorial Fundamentals of Data Compression.)

Suggestions and URLs are welcome.


Note: The intent of the page is to provide useful resources such as software or databases and interesting demonstrations (real time or downloadable). Commercial sites are O.K. if they are technically relevant (or just fun). Purely textual web sites providing only descriptions or papers are not the idea here. Flashy stuff and image files are kept to a minimum on this page to speed loading of this file. You will find plenty of flash in the listed Web pages.

    Multimedia

    The word "multimedia" has been much hyped of late. In addition, it does not make much sense since "media" is already plural and hence "multimedia" seems redundant. Nonetheless, it is generally considered to mean simultaneous consideration of a mix of signal types, typically speech/audio, image/video, graphics/animation, and text. Signal processing is only one component of the field, which also includes networking, databases, and operating systems at its heart. The focus here is on signal processing aspects. See also the individual components, e.g., image processing.

    This page is dedicated to Tom Stockham, the pioneer of digital audio and one of the few of us signal processors to win an Emmy.
