The Network Performing Arts Scene

Ann Doyle (Internet2)
Ann Doyle has directed Internet2's cultural initiatives since 2000, working with a community of innovators, many of whom will be presenting during the workshop. She will give an overview of performing arts collaborations utilizing advanced networks across the globe.

Fundamentals of Sound and Acoustics

Volker Werner (PDV)
Presentation Short introduction in the basics of sound, miking of acoustical instruments and voice, stereo techniques, reduction of acoustical feedback and basic mixing techniques (Equalizer, Dynamics)
Demonstration Practical demonstration of miking techniques (mono and stereo), mixing techniques and feedback suppression

Introduction to EchoDamp

Volker Werner (PDV) & Brian Shephard (USC) - remote speaker
The ECHODamp software application is a multi-channel audio mixer and echo controller designed primarily for the high-bandwidth musical videoteleconference environment which manages echo without impacting the quality of the audio. This session will include a live demonstration with Volker Werner, PDV, from the conference venue with ECHODamp author, Dr. Brian Shepard, at the University of Southern California's Thornton School of Music in Los Angeles.

Special Evening Event "Near in the Distance"

An invitation-only evening event, "Near in the Distance", is being organised by ACOnet, the Austrian research and education networking organisation (NREN), in association with the University of Music and Performing Arts Vienna (mdw) which is hosting the workshop. Participants are automatically registered for this special evening. The LOLA and UltraGrid systems will be showcased during a concert and dance performance that will bring together exceptional Austrian artists and international dancers and musicians based in remote locations. Short discussion panels will take place between and after the performances, where the involved artists and engineers will give an overview of their experience working with one another across a distance but in real time, and what this means for rehearsals.

LOLA Update and Demonstration

Claudio Allocchio (GARR) & Nicola Buso (Conservatorio G. Tartini)
The 'Low LAtency videostreaming system' video conferencing program has been developed with the aim of minimising latency between remote points. Since its first public use at the Network Performing Arts Production Workshop in 2010 at IRCAM, significant experience has been acquired by the community using it, and quite a number of improvements to the system, like support for color video, an even shorter audio/video latency, and now support for audio multi-channel, which will be demonstrated live for the first time by a group of musicians located in different places playing simultaneously.

Psychoacoustics and Applied Psychology

Juerg Jecklin (mdw)
What are the factors for a good musical performance and how can we adapt them in a multi-site situation? What are the benefits and limitations? What information is dropped in the transmission chain and how can it be recovered? Answers and maybe more questions from a new perspective.

DVTS Overview

Claudio Allocchio (GARR)
DVTS has been one of the oldest and most faithful work horses used in remote musical education across the network. Since its adoption it provided the ability to perform remote masterclasses with a very easy and affordable audio/video setup. Explanation of the properties of the DVTS video conferencing system, including its history, components and specifications, such as quality ratios, bandwidths and system requirements. DVTS has come to an updated life recently, with a new version which also supports Mac OSX systems, and other improvements. A demonstration will be given in a dedicated session later during the workshop.

UltraGrid Update

Petr Holub (CESNET)
UltraGrid from Laboratory of Advanced Networking Technologies (SITOLA) is a software implementation of high-quality low-latency video and audio transmissions using commodity PC and Mac hardware. UltraGrid uses uncompressed or very low compression-ratio streams to achieve up to 8K resolution with as low as 100ms end-to-end latency. UltraGrid is used, among others in areas like collaborative environments, medical cinematography, broadcasting application and various educational activities.

The talk will focus on recent updates in several important areas: support for CPU-based low-latency H.264 compression, support for more platforms (Windows port, BlueFish444 cards with sub-field latency), reading/storing video from/to disk, support for up to 8K video, commercial applications including GPU-accelerated JPEG2000 video, etc.

Short terms plans will be briefly discussed, including more sophisticated multi-channel video processing, advanced multi-point modes, and automated orchestration of the environments using CoUniverse framework.

An Artist's Perspective of Network Performing Arts

Ivani Santana UFBA-Br (CAPES) Sonic Arts Reseach Center
The telematic dance is an art configuration in itself, this is the approach of all creative process that Ivani has developed since 2005. The Networked Dance performance understood not as a dance-on-stage replacement, but a new configuration emerged into the heart of the Digital Culture: the Internet. This is her challenge, working with Distributed Dance in several projects with different partners across the world. The goal is to research a specific dance performance created on/for/in/through the Net, that plays with the Net protocol and specificity. Questions arise: How could the delay/latency be used as an aesthetic approach and not as an error? How is the dancer's perceptual system affected when s/he has to interact with a remote partner and with a virtual world? How can we understand the simulacrum of a virtual shared space, and the different times zones convergence? This is an expanded dance, an expanded body.

Audio/Video Systems Live Comparison - Demonstration

Jack Vees (Yale University)
In this session, Yale University will host a live demonstration of video codecs and software solutions of the greatest interest to this community. Workshop attendees will have the opportunity to see and hear a live musician playing over multiple platforms to help determine which is the best set up for their institution. The demonstration will include a discussion of cost, bandwidth requirements, video and audio quality of each platform demonstrated.

ConferenceXP Update

Jose Feghali (Texa Christian University, Forth Worth) - remote speaker
Presentation of this open source, collaborative tool based on virtual classrooms for different uses, such as e-learning and high quality video conferencing. A remote music performance example will be given along with suggestions on microphone and camera selection and placement. Compressed video using different codecs will be demonstrated and tips will be given on how to get good results when combining compressed video with uncompressed audio on the same stream.

CXP's latest developments (including full HD (High Definition) video support and experimentation) will be discussed during the presentation. Fred Videon, from the University of Washington's Center for Collaborative Technologies, will give an overview on the software's development and migration to "open source" status.

Performing Arts Production over Advanced Networks
"Near in the Distance - The Panel discussion"

Chair: Juerg Jecklin (mdw)
New technologies create new opportunities but also new challenges for the world of performing arts. Interactive performances between remote venues bring artists and audience, students and teachers, and even performers together and overcome physical distances and borders. The panel discussion faces several of those challenges including time delay between venues, sharing different spaces and the absence of physical contact between performers and discuss the pros and cons of multi-site interaction.

Report on the introduction of distance learning in traditional higher music education

Marianne Løkke Jakobsen and Thomas Solak, RDAM, Justin Trieger, NWS (The Royal Danish Academy of Music)
Using the right technology may be the starting point, but what about everything else? This presentation shares some experiences with other aspects and success factors in the implementation of instrumental distance learning in a traditional higher music education. How to involve faculty? How to transform the presence of technology to an everyday event? How to deal with the meeting of cultures?

Artists experiences &
Based on almost 20 years of various experience with streaming media, artists from and continue their research in the field of live online (multi)media usage. Both organisations act as laboratories with the goal of enhancing communication by means of networking. One of the central issues is how to reconnect the net to humans.

At the workshop we aim to present the status quo of our ongoing research by means of a networked performance and distributed workspace that includes participants from Linz (Austria), Graz (Austria) and Vienna (Austria). It's a highly experimental work in progress-project, which will go further into the question "how to reconnect the net to humans?" by using a shared infrastructure of audio-visual means - a loose network of artistic attendence based on shareable projections and displays at various remote places and public space.

Hands-on Session in parallel rooms

Experiments with delay

  • LOLA
  • DVTS

Participants will have locally available (in 2 separate rooms) LOLA and DVTS systems, and by adding network delay to the connections, they will be able to experiment live what happens to artistic interaction in different latency conditions. They will be able to have their hands on both the technical part of the experiment, and the possibility to perform artistically while the lab is ongoing. As this session is a hands-on, we would like to get a clear idea of numbers prior to the event, please indicate your interest by registering to the session.
