Tuning Video Redundancy

ABC 1999-2000


This project analyzes the effects of various redundancy techniques on network congestion and on user perceptual quality. A network simulator was used to simulate TCP and UDP data packets across a network. Various parameters were adjusted including traffic mix, bandwidth, router queue length, and redundancy amount. Pre-built movies with various loss and redundancy were used for the perceptual quality user studies. We found no statistical correlation between redundancy and perceptual quality.
