Multichannel video/audio acquisition for immersive conferencing

This paper presents an information-driven audiovisual signal acquisition approach. This approach has several advantages: users are encouraged to assist in signal acquisition; available sensors are managed based on both signal characteristics and users’ suggestions. The problem formulation is consistent with many well-known empirical approaches widely used in previous systems and may provide ana...

Efficient Overlay Audio Conferencing

In this paper, we present a thorough and realistic analysis of audio conferencing over application-level multicast (ALM). Through flexibility and ease-of-deployment, ALM is a compelling alternative group-communication technique to IP Multicast — which has yet to see wide-scale deployment in the Internet. However, proposed ALM techniques suffer from inherent latency inefficiencies, which we show...

Gaze Awareness for Video-Conferencing: A Software Approach

bringing gaze awareness to desktop videoconferencing have relied on hardware solutions. Here, the authors describe their software approach, which tracks participants’ head and eye movements using vision techniques, then uses this information to graphically place the head and eyes in a 3D environment. T he impact of gaze is striking. We all know the experience of “feeling watched,” and it’s hard...

Peer-to-Peer Audio Conferencing

The intention of IP Multicast as a service provided by network infrastructure was to allow groups of hosts to share similar data, leaving the network to deal with the complexities of group membership and routing issues. One natural use for IP Multicast was group conferencing. Adoption of IP Multicast has not been swift, however, leaving conferencing applications designed for use with the servic...
