Pandora is a joint project between Olivetti Research Cambridge and the University of Cambridge Computer Laboratory. The project is investigating the use of multimedia workstations in a working environment with particular emphasis on digital video. It endeavours to place a camera on the desktop to make generation of multimedia documents as easy as producing text. We are aiming to produce a number of new applications as well as to provide insights into the way computer systems should be designed…

An experimental workstation is described which supports digital video and audio in a distributed environment, and which presents this functionality to the user through the medium of a video‐extended
A Multimedia Enhancement Network Device
Research has focussed on the development and implementation of hardware designed to handle continuous multimedia between host-machines and a multi-service network, but so far the systems developed have not been reproducible on a large scale due to the cost of the hardware.
The Design and Implementation of a RAID-3 Multimedia File Server
The architecture of the Disc Brick is described, and some of the hardware and software issues raised by its design are discussed, as well as measurements taken from a Disc Brick in operation and how the observations relate to the original design objectives.
Handling audio and video streams in a distributed environment
The principles involved in this design are now being used in the development of two complementary systems, one of which explodes Pandora by having the camera, microphone, speaker and display as independent units linked only by the LAN.
A software-oriented approach to the design of media processing environments
This paper describes a set of computer-participative applications that demonstrate the present day viability of applications that participate in, i.e., actively process, live media-based information.
ViewStation Applications: Implications for Network Traffic
Applications built on the ViewStation, a distributed multimedia system based on Unix workstations and a gigabit per second local area network, perform intelligent processing on video, as well as straightforward presentation and demonstrate the utility of network-based multimedia systems that deliver audio and video data all the way to the application.
6. Evaluation and Extensions 6.1 Performance Evaluation
  • Computer Science
This chapter presents an evaluation of IMAC and its prototype implementation, designs for un-implemented portions of IMac and suggestions for future research, and a set of requirements for future systems to enable them to better support IMAC implementations.
The ViewStation: a software-intensive approach to media processing and distribution
A set of computer-participative applications are described that demonstrate the present day viability of applications that actively process live media-based information and the affordability and benefits of the software-intensive approach.
Towards Integrated Multimedia Systems: Why and How
This paper elaborates on the key issues for providing multimedia support, including system software needed that meets the real-time demands of audio and video, and a multimedia application interface that is compulsory.


Experiments in Digital Video for Workstations
Experimental work in the use of digital video by computer workstations to gain experience with the handling of video, and to investigate some of the systems aspects of its integration into the workstation environment.
Protocol design for high speed networks
This dissertation describes the design, and an implementation, of the Multi-Service Network architecture and protocol family, which is aimed at supporting the full facilities of asynchronous transfer mode networks by multi-media applications.
The Cambridge Fast Ring Networking System
A discussion is presented of the choices facing a designer as faster speeds for local area networks are contemplated. The 100-Mb/s Cambridge fast ring (CFR) is described. The ring protocol allows one
Layered ATM systems and architectural concepts for subscribers' premises networks
A layered functional model of an ATM open system is presented and the relation with existing packet techniques is studied, and a two-tier SPN architecture is proposed covering both residential and business environments, in line with the modeling principles outlined.
