|Title: ||The telepresence integrated interactive intermedia facility|
|Issue Date: ||May-1992|
|Publisher: ||Ontario Telepresence Project|
|Series/Report no.: ||KMDI Historical Papers;KMDI-HP-93-04|
|Abstract: ||The iiif system is a base to support the use of interactive media. It is intended to
serve as the utility on which a number of interactive media services are based.
Examples of the types of services that the facility is intended to support include a
media space, a video document handling system and, of course, traditional video
The iiif system has the dual purpose of providing a base utility to support re-searchers,
and is the subject of research in and of itself. The general research objec-tive
is to investigate how multimedia technology can be applied to support HCI
research objectives, including the support of cooperative work.
The hub of the utility consists of computer controllable A/V equipment, computer
controlled A/V switches (much like telephone switches) and a server computer to
provide control. The server computer is accessible to people at workstations through
the same networks used for other electronic communications.
The iiif system originated at Rank Xerox's EuroPARC laboratory in 1988. It was
given to the Cavecat project at the University of Toronto in early 1990. The server
was adopted by the CAVECAT project as the basis for its media space. The iiif server
along with other CAVECAT resources were transfered to the Ontario Telepresence
Project at the University of Toronto. This note documents the current state of iiif
evolution at the University of Toronto. The design includes server software, device
support, network communications and client stub implementations for common
workstations. It does not inciude a user interface for the administrator or the users
of the facility.
The iiif server provides the infrastructure necessary for other servers to function.
The Smart Server uses the information within iiif in order to update a user's
interface with a correct representation of the state of the media space. The Video
and Voice servers will use iiif to retrieve and present different tvpes of media clips
such as snapshots of a person's office or speech through iiif's audio visual network.
The iiif server is written in C. There are approximately 38,000 lines of code divided
into operation specific modules. Berkley System Unix is the operating system for
which the iiif server has been developed.|
