We describe an architecture for distributed collaborative visualization that integrates video conferencing, distributed data management and grid technologies as well as tangible interaction devices for visualization. High-speed, low-latency optical networks support highquality collaborative interaction and remote visualization of large data.
Latency-sensitive data distribution and media streaming is a part of many network-centric applications. Based on our previous practical experiences with interactive high-quality media distribution and orchestration of network-centric collaborative environments, we have developed an automated planner for media stream distribution in environments where(More)
Using internet for media-based real-time collaboration has become widespread activity. In this paper, we present a framework called CoUniverse, designed for building realtime user-empowered collaborative environments to work primarily on high-speed networks with true high-bandwidth applications such as uncompressed high-definition video. The system is(More)
We describe a high-quality collaborative environment that uses High-Definition (HD) video to achieve near realistic perception of a remote site. The capture part, consisting of a HD camera, Centaurus HD-SDI capture card, and UltraGrid software, produces a 1.5 Gbps UDP data stream of uncompressed HD video that is transferred over a 10GE network interface to(More)
Providing secure, extensible, pervasive and easy to implement collaborative environment for medical applications poses significant challenge for state-of-the-art computer systems and networks. In this paper, we describe such a collaborative environment developed for Ithanet project, based on Grid authentication mechanisms. Significant effort has been put(More)
This article describes a distributed classroom experiment carried out by five universities in the US and Europe at the beginning of 2007. This experiment was motivated by the emergence of new digital media technology supporting uncompressed high-definition video capture, transport and display as well as the networking services required for its deployment(More)
In this thesis, we focus our work on two classes of multimedia data distribution and processing problems: synchronous or interactive, which require as low latency as possible, and asynchronous or non-interactive, where latency is not so restrictive. In Part I, we study scalable and user-empowered infrastructure for synchronous data distribution and(More)
The talk will showcase the technology developed by CESNET for very high quality, low-latency media transmissions over high-speed networks and its applications in various fields including medicine, arts, broadcasting and cinematography, sports or education. The talk covers different aspects and demands of such applications and how they can be implemented(More)
