"From Remote Media Immersion to Distributed Immersive Performance"
by A.A. Sawchuk, E. Chew, R. Zimmermann, C. Papadopoulos and C. Kyriakakis

ABSTRACT: We present the architecture, technology and experimental
applications of a real-time, multi-site, interactive and collaborative
environment called Distributed Immersive Performance (DIP).  The
objective of DIP is to develop the technology for live, interactive
musical performances in which the participants - subsets of musicians,
the conductor and the audience - are in different physical locations
and are interconnected by very high fidelity multichannel audio and
video links.  DIP is a specific realization of broader immersive
technology - the creation of the complete aural and visual ambience
that places a person or a group of people in a virtual space where
they can experience events occurring at a remote site or communicate
naturally regardless of their location.  The DIP experimental system
has interaction sites and servers in different locations on the USC
campus and at several partners, including the New World Symphony of
Miami Beach, FL.  The sites have different types of equipment to test
the effects of video and audio fidelity on the ease of use and
functionality for different applications.  Many sites have
high-definition (HD) video or digital video (DV) quality images
projected onto wide screen wall displays completely integrated with an
immersive audio reproduction system for a seamless, fully
three-dimensional aural environment with the correct spatial sound
localization for participants.  The system is capable of storage and
playback of the many streams of synchronized audio and video data
(immersidata), and utilizes novel protocols for the low-latency,
seamless, synchronized real-time delivery of immersidata over local
area networks and wide-area networks such as Internet2.  We discuss
several recent interactive experiments using the system and many
technical challenges common to the DIP scenario and a broader range of
applications.  These challenges include: (1). low latency continuous
media (CM) stream transmission, synchronization and data loss
management; (2). low latency, real-time video and multichannel
immersive audio acquisition and rendering; (3). real-time continuous
media stream recording, storage, playback; (4). human factors studies:
psychophysical, perceptual, artistic, performance evaluation;
(5). robust integration of all these technical areas into a seamless
presentation to the participants.
