This paper describes a subjective test performed with 60 viewers over the age of 18 years and 570 young students, the majority being 10 or 11 years old, to understand the relative annoyance caused by various transmission impairments when viewing television content. Our goal was to compare errors associated with broadcast and multicast delivery, which appear as areas of extreme color or tearing of the image, with errors associated with adaptive bit rate unicast, such as interruptions and quality

A significant level of consistency was found over all of the results collected. Interruptions were the most annoying impairment, with multiple short interruptions being more annoying than a single longer one, and with missing content being more annoying than simply pausing. We found more tolerance to quality variation on tablets and found that younger adults are more annoyed by impairments on tablets and older adults are more annoyed when watching on the TV. We found the young students to have similar views to the adults and found them to be capable of participating in subjective tests.
