This thesis explores a technique for the fusion of streamed audio and video services for real-time applications. It discusses certain novel techniques used to overcome the problems with video and audio synchronization over the Internet of a tele-bot. We have developed a demonstration called the WAX, at the Network-Centric Applied Research Team (N-CART) laboratory located within the School of Computer Science at Ryerson University. WAX is equipped with an onboard camera and a microphone, as well as a 2.4 GHz wireless transceiver for transmitting video and audio feeds, and at the same time receiving commands from the WAX robot server. By launching a web browser and loading the Java client applets, a user can see as well as hear what is around WAX in near real-time, while being able to move the robot around its environment.

Abstract. It is proposed that the concept of transparent telepresence can be closely approached through high fidelity technological mediation. It is argued that the matching of the system capabilities to those of the human user will yield a strong sense of immersion and presence at a remote site. Some applications of such a system are noted. The concept is explained and critical system elements are described together with an overview of some of the necessary system specifications.

This paper presents the embedded realization and experimental evaluation of a media stream scheduler on Network Interface (NI) CoProcessor boards. When using media frames as scheduling units, the scheduler is able to operate in real-time on streams traversing the CoProcessor, resulting in its ability to stream video to remote clients at real-time rates. The contributions of this paper are its detailed evaluation of the effects of placing application or kernel-level functionality, like packet scheduling on NIs, rather than the host machines to which they are attached. The main benefits of such placement are 1) that traffic is eliminated from the host bus and memory subsystem, thereby allowing increased host CPU utilization for other tasks, and 2) that NI-based scheduling is immune to host-CPU loading, unlike host-based media schedulers that are easily affected even by transient load conditions. An outcome of this work is a proposed cluster architecture for building scalable media servers by distributing schedulers and media stream producers across the multiple NIs used by a single server and by clustering a number of such servers using commodity network hardware and software.
