TL;DR: This research addresses four areas of content-based video management, including time codes, image frames, pixels, and frames, which are based on pixels rather than perceived content.
Abstract: Video management tools and techniques are based on pixels rather than perceived content. Thus, state-of-the-art video editing systems can easily manipulate such things as time codes and image frames, but they cannot "know," for example, what a basketball is. Our research addresses four areas of content-based video management. >

TL;DR: The author explores why the button so dominates today's hypermedia systems and why this must change.
Abstract: In his keynote address to the Hypertext 91 conference, Frank Halasz described "ending the tyranny of the link" as a major issue facing the hypermedia research community at that time. The greatest problem is not that users always focus on buttons because they know a button indicates a link or connection of some kind. Just the opposite, users expect buttons in hypermedia systems, so if no buttons are indicated, they assume there are no links. The new, open hypermedia systems readily permit the dynamic generation of links and the application of links to standard desktop computing packages not under the hypermedia system's control. In such scenarios, buttons rapidly become less and less necessary, or useful, as a means of indicating a link. Indeed, since a button's main purpose in a hypermedia system is to indicate the presence of links, buttons should become redundant as we move toward systems where links themselves are virtual entities. Unfortunately, this is unlikely to happen whilst hypermedia authors and users have such a fixation on buttons. The author explores why the button so dominates today's hypermedia systems and why this must change. >

TL;DR: The fax-MIME gateway takes advantage of developments to offer fax services to Internet users and Internet services to multimedia fax users.
Abstract: New standards may help bridge the rapidly growing communities of the Internet and facsimile machine users. One of these is the Internet standard proposed in July 1992 which provides enhanced capabilities for e-mail. This new standard, Multipurpose Internet Mail Extensions (MIME), lets users exchange multiple-media mail messages over the Internet. The fax-MIME gateway takes advantage of these developments to offer fax services to Internet users and Internet services to multimedia fax users. >

TL;DR: This work summarizes parts of the Bermed effort, concentrating on how it integrates patient data and supports physician cooperation through remote access to documents and multimedia desktop conferencing.
Abstract: Bermed logically integrates distributed, multimedia patient data and gives authorized physicians transparent access to it through a single workstation. In conjunction with this integration, the project provides asynchronous remote access to the data and synchronous desktop conferencing between physicians connected by ATM and ISDN wide area networks. Although other projects around the world have similar aims and implementations, Bermed seems unique in its wide area logical integration of distributed patient records covering multiple specialties and in its large-scale field trials using advanced broadband communications. We summarize parts of the Bermed effort, concentrating on how it integrates patient data and supports physician cooperation through remote access to documents and multimedia desktop conferencing. >

TL;DR: The article discusses the World Wide Web, focusing on using the WWW to support commerce-electronic marketing and digital publishing, and how more organizations will use the net for innovative ways of providing online magazines and electronic commerce.
Abstract: The article discusses the World Wide Web (Internet), focusing on using the WWW to support commerce-electronic marketing and digital publishing. Businesses are increasingly using the Web for advertising and electronic catalog based retail sales. Immediate benefits from the use of the technology include the ability to monitor and track the behavior of one's customers, provided by access statistics the WWW server maintains. In addition, many aspects of managing customer interaction can be automated, for example, submission and collection of customer surveys, billing, and so forth. In the future, more organizations will use the net for innovative ways of providing online magazines and electronic commerce. Although the approximately 20 million Internet users represent only a small fraction of the world population, the dramatic growth of the market in recent years will continue to lure commerce online. >

TL;DR: The Medusa project at Olivetti Research aims to provide a networked multimedia environment in which many streams of multimedia data, perhaps thousands, are active simultaneously, using a peer-to-peer architecture to controlnetworked multimedia devices.
Abstract: The Medusa project at Olivetti Research aims to provide a networked multimedia environment in which many streams of multimedia data, perhaps thousands, are active simultaneously. Medusa uses a peer-to-peer architecture to control networked multimedia devices. In the software model presented to the applications programmer, active objects called modules represent cameras, displays, format converters, and so on. Data flows from module to module through connections between them, with proxy modules to restrict access for security reasons. The Medusa project is based on hardware that is a collection of asynchronous transfer mode (ATM) direct peripherals, including cameras, audio systems, multimedia storage servers, LCD displays, and televisions, as well as ATM networked workstations. >

TL;DR: Through the cooperation of network service providers and campus network managers who volunteered workstations as nodes, the MBone was built as an experimental multicast Internet Protocol (IF) testbed for live audio and video transmission.
Abstract: Stephen Casner University of Southern California, In formation Sciences Institute T he Multicast Backbone, called MBone, is becoming a popular place in cyberspace In the same way people asked, “Are you on the Internet?“, they now ask, “Are you on the MBone?” Through the cooperation of network service providers and campus network managers who volunteered workstations as nodes, the MBone was built as an experimental multicast Internet Protocol (IF) testbed for live audio and video transmission Although it is still experimental, people have found MBone service useful and have come to expect it Perhaps some have even begun to depend on it How did MBone become so important? It meets a need-the growing need for natural, realtime, human communication through computer networks

TL;DR: The author believes multimedia ethnography is a platform for multiloguing that acts as an electronic forum for discussion and social intercourse among multiple users that encourages a shared vision that enables multimedia stories to become more valid accounts.
Abstract: The time has come to look beyond the usual systems approach of multimedia productions and ask an ethnographic question: where is the real story? Is the story in the mind of the reporting "authors" as they create these productions? Is it located in the production (often referred to as the text or document) itself? Or, is it in the minds of "readers" as they sew together fragments of the story using sound, video and text? The author believes multimedia ethnography is a platform for multiloguing that acts as an electronic forum for discussion and social intercourse among multiple users. This platform encourages a shared vision that enables multimedia stories to become more valid accounts. Thus, multiloguing plays two roles: dialogue is replaced by many people engaging in multiple levels of conversation; and the process of reaching conclusions includes logging (selecting, coding, and analyzing) parts of stories from multiple perspectives. >
TL;DR: An interdisciplinary team developed a prototype computer supported cooperative work application, implemented on Telstra's experimental multimedia communications platform, and demonstrated it to major Australian film and television companies.
Abstract: During preproduction, film and television companies consider visuals in deciding on cast, location, and special effects. Using telecommunications would allow these decision makers to confer at a distance, reducing travel and delays caused by shipping materials back and forth. To support preproduction, an interdisciplinary team developed a prototype computer supported cooperative work application, implemented on Telstra's experimental multimedia communications platform, and demonstrated it to major Australian film and television companies. >
