With the increasing demand for streaming media, it is important to study the effects of quality defects in a video. We concentrated on how buffers and interrupts can impact a user's quality of experience by measuring how a user becomes annoyed with their presence. We determined annoyance by having the user watch a series of videos with different buffer times or interrupt count, asking for the perceived annoyance afterward. The results from 37 users show a polynomial relationship between buffer time and annoyance and a logarithmic relationship between interrupt count and annoyance. These results can be used by streaming services to understand how buffers and interrupts affect users, which can help find a better balance that minimizes annoyance.
