Introduction to Objective Video Quality Metrics and Spectrum Sharing
Video is a booming industry: content is embedded on many Web sites, delivered over the Internet, and streamed to mobile devices. Cisco statistics indicate that mobile video traffic exceeded 50% for the first time in 2012, and two-thirds of the world’s mobile data traffic will be video by 2017. This has produced a need for objective video quality metrics. The different approaches will be introduced and summarized, and the advantages and disadvantages identified. Research opportunities will be mentioned. We will explore the role of committees, model validation and standards.This talk will then summarize the history of spectrum sharing, with a focus on Unlicensed National Information Infrastructure (U-NII) devices. This history demonstrates the real-world progression from theory to commercial availability.
