In this paper we discuss the implementation of receiver-driven rate adaptation using multicast and SNR scalability as supported by Version 2 of ITU-T Recommendation H.263-Video Coding for Low Bit Rate Communication. We compare the layered bit stream approach to receiver-driven rate adaptivity to the approach using multiple independent bit streams. We show(More)
Formal diagnostic methods are emerging from the machine-learning research community and beginning to find application in Intel. In this paper we give an overview of these methods and the potential they show for improving diagnostic procedures in operational environments. We present an historical overview of Bayes networks and discuss how they can be applied(More)
Today's Information Technology (IT) organizations face significant challenges in delivering business value in these times of rapid architectural evolution as well as challenges in their ability to manage, provision, trust, and integrate the various elements of IT systems. An important aspect of these challenges is the impact IT has on the user and the(More)
Communication is vital in any workplace. However, as workers become less tied to their desktops and computers, the need to provide them with a flexible, easy to use, mobile method of communication becomes more necessary. This is particularly true in "non-traditional" workplaces like factories or hospitals. Cell phones, PDA's, and walkie-talkies provide the(More)
In looking forward to more natural telecollaboration, we can anticipate that the teleconferencing system of the future will enable participants at distant locations to share the same virtual space. The visual object of each participant can be transmitted to the other sites and be rendered from an individual perspective. This thesis presents an effort,(More)
