Medical Applications and Technical Standardization of Teleconferencing

Technical Controversy in International Standardization

The development of larger technical systems relies on the coordination of autonomous action of a multitude of individuals and organizations. Institutional settings, often neglected in the analysis of technical development, help to achieve such coordination. Our analysis of international technical standardization in telecommunications highlights an institutionalized process aiming at the creatio...

Disparity map coding for 3D teleconferencing applications

In this paper we present a combination of three steps to code a disparity map for 3D teleconferencing applications. First we introduce a new disparity map format, the chain map, which has a very low inherent redundancy. Additional advantages of this map are: one single bidirectional map in stead of the usual two unidirectional vector fields, explicit indication of occlusions, no upper or lower ...

Advanced Applications for Multichannel Teleconferencing Audio Systems

This thesis deals with advanced digital signal processing techniques applied to multichannel teleconferencing audio systems, focusing on their benefits and drawbacks. A teleconferencing system should provide a realistic representation of visual and sound fields, allowing a natural communication among participants anywhere in the world as they were all in the same room. In this context, the work...

Wideband Stereo Speech Coding for Teleconferencing Applications

Almost a ll voice communications are based on monophonic narrowband speech. Wideband stereophonic communications provide a more natural sounding environment. This holds especially true for teleconferencing applications, where the localization information in the stereo signal adds a new dimension to the communication. As of today, there is no standardized speech codec with full stereo support. S...
