Madcap (project)
Madcap is a prototype system for using computers to automatically segment and highlight a video stream that was designed by Dan Russell's group at PARC. The digital video of weekly forums was stored on a media server, any events such as clapping were marked and time-stamped. Member notes from attendees with laptops were stored. The audio stream was transcribed. All these were used as annotations and were cross indexed. The development of this system is mentioned in John Seely Brown John Seely Brown (born 1940), also known as "JSB", is an American researcher who specializes in organizational studies with a particular bend towards the organizational implications of computer-supported activities. Brown served as Director of Xer ...'s work ''Growing up Digital'' and his book ''The Social Life of Information''.

Computers
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links bill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Stream
Video on demand (VOD) is a media distribution system that allows users to access videos without a traditional video playback device and the constraints of a typical static broadcasting schedule. In the 20th century, broadcasting in the form of over-the-air programming was the most common form of media distribution. As Internet and IPTV technologies continued to develop in the 1990s, consumers began to gravitate towards non-traditional modes of content consumption, which culminated in the arrival of VOD on televisions and personal computers. Unlike broadcast television, VOD systems initially required each user to have an Internet connection with considerable bandwidth to access each system's content. In 2000, the Fraunhofer Institute IIS developed the JPEG2000 codec, which enabled the distribution of movies via Digital Cinema Packages. This technology has since expanded its services from feature-film productions to include broadcast television programmes and has led to lower bandw ...

PARC (company)
PARC (Palo Alto Research Center; formerly Xerox PARC) is a research and development company in Palo Alto, California. Founded in 1969 by Jacob E. "Jack" Goldman, chief scientist of Xerox Corporation, the company was originally a division of Xerox, tasked with creating computer technology-related products and hardware systems. Xerox PARC has been at the heart of numerous revolutionary computer developments, including laser printing, Ethernet, the modern personal computer, GUI (graphical user interface) and desktop paradigm, object-oriented programming, ubiquitous computing, electronic paper, a-Si (amorphous silicon) applications, the computer mouse, and VLSI ( very-large-scale integration) for semiconductors. Unlike Xerox's existing research laboratory in Rochester, New York, which focused on refining and expanding the company's copier business, Goldman's “Advanced Scientific & Systems Laboratory” aimed to pioneer new technologies in advanced physics, materials science, and ...

Media Server
A media server is a computer appliance or an application software that stores digital media (video, audio or images) and makes it available over a network. Media servers range from servers that provide video on demand to smaller personal computers or NAS (Network Attached Storage) for the home. Purpose By definition, a media server is a device that simply stores and shares media. This definition is vague, and can allow several different devices to be called media servers. It may be a NAS drive, a home theater PC running Windows XP Media Center Edition, MediaPortal or MythTV, or a commercial web server that hosts media for a large web site. In a home setting, a media server acts as an aggregator of information: video, audio, photos, books, etc. These different types of media (whether they originated on DVD, CD, digital camera, or in physical form) are stored on the media server's hard drive. Access to these is then available from a central location. It may also be used to run s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Seely Brown
John Seely Brown (born 1940), also known as "JSB", is an American researcher who specializes in organizational studies with a particular bend towards the organizational implications of computer-supported activities. Brown served as Director of Xerox PARC from 1990 to 2000 and as Chief Scientist at Xerox from 1992 to 2002; during this time the company played a leading role in the development of numerous influential computer technologies. Brown is the co-author of ''The Social Life of Information,'' a 2000 book which analyzes the adoption of information technologies. Early life John Seely Brown was born in 1940 in Utica, New York. Brown graduated from Brown University in 1962 with degrees in physics and mathematics. He received a Ph.D. from the University of Michigan in computer and communication sciences in 1970. Career His research interests include the management of radical innovation, digital culture, ubiquitous computing, autonomous computing and organizational learning. JSB i ...
