Experimental results show the proposed policy increases overall system lifetime by 20% on average.
Microsoft PowerPoint - WirelessCluster_PresVideoguy
This document analyzes delays in unicast video streaming over IEEE 802.11 WLAN networks. It describes conducting an experiment using a testbed with a Darwin Streaming Server and WLAN probe to capture packets. The analysis found that video bitrate variations, packetization scheme, bandwidth load, and frame-based nature of video all impacted mean delay. Bursts of packets from video frames caused per-packet delay to increase in a sawtooth pattern. Increasing uplink load was also found to affect delay variations.
Proxy Cache Management for Fine-Grained Scalable Video StreamingVideoguy
This document proposes a novel video caching framework that uses MPEG-4 Fine-Grained Scalable (FGS) video with post-encoding rate control to achieve low-cost and fine-grained rate adaptation.

3. Basics Introduction - 1
Introduction
QuickTime Conferencing (QTC) is a system software
extension. It comes with Apple Media Conference, an
application program you use to set up video conferences,
collaborate with others, exchange live video and sound, and
share information over a network.
Apple Media Conference takes advantage of the networking
capability already built into your computer so you can
connect with other video conferencing systems over a local
or wide area network, such as an AppleTalk local area
network or the TCP/IP Internet.
This manual provides a description of the QuickTime
Conferencing products and tools, their specifications, a
troubleshooting guide, and a parts list.
