Universities Research Mobile Video Quality Measurement

Fredric Paul reported to ReadWriteWeb that "Intel, Cisco and Verizon are pouring $3.3 million into research at five prominent universities to improve video delivery over wireless networks. The first goal of the Video Aware Wireless Networks (VAWN) program? Find a good way to measure mobile video quality .. The research is important to finding ways to deliver the best video experience to the most people when the networks get overloaded; that is, minimize the problems that annoy people most"
"Because viewers perceive quality differently depending on what they're watching - sports versus talking heads, for example - quality isn't about throughput but experience .. Measuring subjective video quality is only the first step toward the larger goal of delivering high-quality video while boosting network capacity to handle the ever-increasing flood of data. The issue can’t be ignored: In 5 years an estimated 90% of Net traffic will be video, and 66% of mobile traffic will be video"
"The project is now in year two of its three-year, $1.1 million-per-year plan. By then end of the program, the VAWN team hopes to have a good method to measure perceived video quality, as well as algorithms and software tools to use that measurement to make network decisions".
