CSI Student wins best paper award at top Wireless Communications Conference

Congratulations to CSI student, Patrick McDonagh, who won a best paper award at WPMC’11 (14th International Symposium on Wireless Personal Multimedia Communications) for his paper entitled “Investigation of Scalable Video Delivery using H.264 SVC on an LTE network”. Patrick is working with the Performance Engineering Lab in CSI with Profs Liam Murphy and John Murphy.

The winning paper describes video delivery in cellular wireless networks.  In particular, it studies a video codec that allows the quality of a video transmission to be adapted according to how busy the network is. It investigates how video quality is affected as the transmission is adapted to different amounts of congestion in a 4G wireless network, including how the video quality might be monitored. The significance of this work lies in its use of methods for measuring video quality, which do not need access to the original video, meaning they could be used in a "real-world" video delivery senario.
