This paper provides an overview of policies and strategies for broadband infrastructure and access, and broadband video communication development and use in First Nation communities in Canada. Although using broadband for video communication remains
Immersive multi-user 3D video communication
free download
The interest in immersive video conference systems exists now for many years from both sides, the commercialization point of view as well as from a research perspective. Nevertheless, so far the user acceptance of such systems was still very limited. This situation
The effect of spatial cues in augmented reality video conferencing

However video communication systems have not spread widely yet because they have some technical difficulties In the current situation, system developments with the consideration of human factors would be more important for the video communication
Eye contact as a determinant of social presence in video communication

In this paper we present the preliminary results on the validity of behavioural measures and their effectiveness to discriminate between differently designed video communication systems. In an experiment we investigated how video communication systems with and
Video communication system supporting spatial cues of mobile users
free download
We propose a novel video mediation method that immerses remote users in a virtual shared space. In the implemented system using this method, video cameras and screens surround users, and on the screens placed behind them remote users and physical or virtual objects
Interpreting, video communication and the sequential reshaping of institutional talk in the bilingual and distributed courtroom.
free download
This article presents the first naturalistic study of courtroom interpreting with a video link and a remote defendant appearing from his prison, based on extensive video recordings and ethnographic observations made during pre-trial hearings in France. Working within a video
Adaptive forward error correction for real-time internet video
free download
Abstract Real-time video communication over packet networks is attracting a lot of attention for applications such as distributed collaborative work, teleteaching and telemedicine. Due to its sensitivity to delay, real-time communication
Robust image and video communication for mobile multimedia
free download
What characterizes mobile multimedia is multiple signal sources, a multitude of applications, and transmission over channels with limited bandwidth and power, plus varying noise and attenuation. To cope with these variabilities new and improved communication systems
