Kernel support for live digital audio and video

Kernel Support for Live Digital Audio and Video

We have developed a real-time operating system kernel which has been used to support the transmission and reception of streams of live digital audio and video in real-time as part of a workstation-based conferencing application. An experimental environment consisting of a number of workstations interconnected with a 16 Mbit token ring has been created and used to evaluate quantitatively the per...

QoS Support for Video & Audio Multipeer

The nature of distributed multimedia applications is such that they require multipeer communication support mechanisms. The multimedia traffic needs to be delivered to endsystems, networks and end-users in a form that they can handle while satisfying the constraints imposed by the multimedia application. Quality of Service (QoS) mechanisms that can ensure full quality media playout at high-perf...

System Software and Hardware Support Considerations for Digital Video and Audio Computing

Digital video and audio (DVA) NO presents special problems to a computer system’s underlying support software and hardware. These problems are due to the high data rates and timing constraints of DVA. To address these problems, more efficient data movement (minimizing data copying wherever possible), and better control over low-level timing of I t 0 transfers, is required. System sofrware must ...
