My Past Academic R&D Work
|
1. My
Ph.D. research mainly focused on some system level issues related with real-time
multimedia content delivery (such as audio and video) over packet networks. A
totally passive yet highly capable synchronization control framework was
proposed to alleviate the performance penalty introduced by transport
impairment which is unavoidable on a “best-effort” packet
networks. A rigorous quantitative analysis has been performed on the dynamics
of the mechanism and prototype systems were built to demonstrate the effectiveness. A real system I built -- Wi-Fi based mobile wireless audio and video conferencing on PDAs . A system overview is here. A rather complete on-line report is presented HERE. A related teaching work is here. Journal publications
produced during this work: 1) Haining Liu and Magda El Zarki, “An adaptive delay and synchronization control scheme for Wi-Fi based Audio/Video conferencing”, in Special Issue on Wireless QoS Support, ACM Wireless Networks, 2005.

2. I’ve
also been able to accomplish some other work during my graduate study at PENN
and UCI. Here are the snapshots of those
worth-of-mention's: 1) An Interactive Object Based Multimedia System for IP Networks. 2) QoS Management Architecture for Home
Networks.
An actual product using this idea (or similar) is described here. 3) The Upenn Cyber Brokerage System. 4) Many-to-Many Net-Chatting System with Text and Still Images 5) A real state-of-art broadband
network I designed and built in 2000! |
