Technologies
Access Grid
The Access Grid is an ensemble of resources including multimedia large-format displays, presentation and interactive environments, and interfaces to Grid middleware and to visualization environments.
DVgrab
dvgrab receives audio and video data from a digital camcorder via an
IEEE 1394 (widely known as FireWire) link and stores them into an AVI
file. It supports saving the data as raw frames, AVI type 1, AVI type 2,
and image files.

DVswitch
DVswitch is a digital video mixer intended for interactive live mixing of several incoming DV video streams. Currently DVswitch can combine audio from one source with video from another and can combine two video streams with a picture-in-picture effect. Further mixing effects are planned. It works solely with the DV format since it is widely supported by camcorders and it allows for low latency display and cutting.

DVTS
DVTS(Digital Video Transport System) is software which enables DV
(Digital Video) or HDV distribution on the Internet.

EchoDamp
The ECHODamp™ software application is a multi-channel audio mixer and echo controller designed primarily for the High-Bandwith Musical Videoteleconference environment. Its intuitive and easy-to-use controls work with nearly any 4X4 hardware audio interface that supports CoreAudio on the Macintosh, or MME, DirectSound, or ASIO on the Windows PC.
EyesWeb XMI and EyesWeb Mobile
EyesWeb XMI is a distributed, open software platform for the development of real-time, interactive, multimodal applications. It supports capture from many devices (e.g., industry and high-speed videocameras, Qualysis motion capture system, webcams, Microsoft Kinect, multichannel audio inputs, physiological sensors, accelerometers), and includes libraries for networked communication, multimodal analysis of qualities of human behaviour, non-verbal expressive gesture, social signals (e.g. entrainment, cohesion, leadership, dominance, salience in a group of people). EyesWeb was used in CO-ME-DI-A to develop the “An Invisible Line” networked interactive installation by Corrado Canepa and Andrea Cera.
FFmpeg
FFMPEG is a free software / open source project that produces libraries
and programs for handling multimedia data.
The most notable parts of FFmpeg are libavcodec, an audio/video codec
library used by several other projects, libavformat, an audio/video
container mux and demux library and the ffmpeg command line program for
transcoding multimedia files.
FFmpeg2Theora
ffmpeg2theora is a very useful application that enables you to
manipulate all kinds of video with the Ogg Theora video file format
(‘codec’).

GStreamer
GStreamer is a library for constructing graphs of media-handling components. The applications it supports range from simple Ogg/Vorbis playback, audio/video streaming to complex audio (mixing) and video (non-linear editing) processing.
Applications can take advantage of advances in codec and filter technology transparently
H323 (client Xmeeting, Ekiga, Polycom)
H323 is an umbrella Recommendation from the ITU Telecommunication
Standardization Sector (ITU-T) that defines the protocols to provide
audio-visual communication sessions on any packet network. The H.323
standard addresses call signaling and control, multimedia transport and
control, and bandwidth control for point-to-point and multi-point
conferences.

HTML5
HTML5 is the next major revision of HTML (Hypertext Markup Language),
the core markup language of the World Wide Web. The Web Hypertext
Application Technology
HTML5 aims to reduce the need for proprietary plug-in-based rich
Internet application (RIA) technologies such as Adobe Flash, Microsoft
Silverlight, and Sun JavaFX.

Icecast
is a streaming media project released as free sotware maintained by the Xiph.org Foundation. The Icecast server is capable of streaming content as Vorbis over standard HTTP, Theora over HTTP, MP3 over the protocol used by Shoutcast, AAC, and NSV over the SHOUTcast protocol. It uses external programs, called “source clients”, to originate the streams. The source runs typically in the place where the audio is generated (e. g. a studio) and the Icecast server in a place where a lot of bandwidth is available.
Iperf
Iperf is a commonly used network testing tool that can create TCP and
UDP data streams and measure the throughput of a network that is
carrying them.

Jacktrip
JackTrip is A System for High-Quality Audio Network Performance over the
Internet.
It supports any number of channels (as many as the computer/network can
handle) of bidirectional, high quality, uncompressed audio signal
steaming.

Pure Data
Pd (aka Pure Data) is a real-time graphical programming environment for audio, video, and graphical processing. It is the third major branch of the family of patcher programming languages known as Max (Max/FTS, ISPW Max, Max/MSP, jMax, etc.) originally developed by Miller Puckette and company at IRCAM. The core of Pd is written and maintained by Miller Puckette and includes the work of many developers, making the whole package very much a community effort.
Quintet.net
Quintet.net is an interactive networked multimedia performance environment invented and developed by composer and computer musician Georg Hajdu. It enables up to five performers to play music over the Internet under the control of a “conductor.” The environment, which was programmed with the graphical programming language Max/MSP consists of four components: the Server, the Client, the Conductor as well as the Viewer add-on.
Scenic
Scenic is an on stage telepresence system that allows for real time transmission of audiovisual data over any IP network. Telepresence systems can be used in various artistic contexts, so that two different creative spaces can communicate with each other or present a combined performance. Scenic provides different performance schemes that allow a maximum number of users to participate in a network of learning, research and artistic creation anywhere in the world (bandwidth permitting).

Skype
Skype is a software application that allows users to make voice calls
over the Internet. Additional features include instant messaging, file
transfer and video conferencing.
VLC
VLC media player is an open source media player and multimedia framework
written by the VideoLAN project
VLC is a portable multimedia player, encoder, and streamer supporting
many audio and video codecs and file formats as well as DVDs, VCDs, and
various streaming protocols. It is able to stream over networks and to
transcode multimedia files and save them into various formats.
