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The list is unfortunately out of date and in desperate need of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.

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.
