Abstract
Due to the increasing user expectation on watching experience, moving web high
quality video streaming content from the small screen in mobile devices to the
larger TV screen has become popular. It is crucial to develop video quality metrics
to measure the quality change for various devices or network conditions. In this
paper, we propose an automated scoring system to quantify user satisfaction. We
compare the quality of local videos with the videos transmitted to a TV. Four video
quality metrics, namely Image Quality, Rendering Quality, Freeze Time Ratio and
Rate of Freeze Events are used to measure video quality change during web content
mirroring. To measure image quality and rendering quality, we compare the matched
frames between the source video and the destination video using barcode tools.
Freeze time ratio and rate of freeze events are measured after extracting video
timestamps. Several user studies are conducted to evaluate the impact of each
objective video quality metric on the subjective user watching experience.
