....and a graphical user interface to the video mail retrieval system. 2 Medusa: Multimedia via Networked ATM The Medusa Project at Olivetti Research Ltd (ORL) is an experiment in sending many streams of digital audio and video over a prototype 100 Megabit per second switched ATM network [3, 4]. The ATM fabric covers all rooms at the laboratory and some 200 network connections are in place. Figure 1 shows a typical Medusa installation. Optical fibre extends the network to the University Engineering Department and the University Computer Laboratory in Cambridge. An ATM network has useful ....

MEDUSA: MULTIMEDIA ON AN ATM NET WORK The Medusa Project at ORL is a novel and extensive experiment in sending many streams of digital audio and video over a prototype 100 Megabit per second switched ATM (Asynchronous Transfer Mode) network [6, 9]. Some 200 network connections cover all laboratory rooms; optical fibre extends the network to the University Engineering Department and the University Computer Laboratory. An ATM network s high bandwidth, low latency, and low transit time jitter make it an appropriate medium for multimedia ....

....from its relevance to research into artificial intelligence, the importance of face identification stems from its numerous potential applications. A successful system could be used for building and workstation security [3] criminal identification, credit card verification and video mail retrieval [5]. This paper presents a new architecture to describe facial features that uses continuous density Hidden Markov Models (HMMs) 11] Face images are auto matically segmented into horizontal regions, each of which is represented in the model by a facial band [13] Faces are treated as ....

MEDUSA: MULTIMEDIA ON AN ATM NETWORK The Medusa Project at ORL is a novel and extensive experiment in sending multiple simultaneous streams of digital audio and video over a prototype 100 Megabit per second switched ATM (Asynchronous Transfer Mode) network [7, 15]. A number of ATM Network Endpoints have been developed enabling the direct connection to the network of microphones, speakers, cameras, disk systems and LCD displays. This concept of exploding the workstation across the network has provided a very adaptable and easily Figure 2. MDMaiI: Medusa ....

....of ATM direct peripherals , including cameras, microphones, loudspeakers and multimedia file servers, as well as ATM networked workstations. Each of the direct peripherals is a small computer built around an ARM processor which is connected to an input or output device and to the ATM network [7,9]. Each of these computers runs an in house micro kernel called ATMOS which was designed specifically for such networked embedded real time systems. In more traditional multimedia systems the input output devices would be attached to a workstation bus and the workstation would be connected to a ....
