Evaluating the Influence of Second Screen Usage on Video Quality Perception

This study investigates to what extent subjects are influenced by second screen (2nd screen) usage in terms of perceiving and evaluating video quality impairments in an adaptive streaming scenario. A controlled between subjects test was set up to ascertain whether subjects that are using a related 2nd screen are less sensitive to video quality impairments compared to subjects not using a 2nd screen. Our results show a significant influence of 2nd screen usage in terms of impairment detection and evaluation. However, tests to measure whether this was attributable to a divided attention showed no effect.
