This website is part of an experiment on video delivery algorithms. By watching videos on this website, you represent that you are at least 18 years of age, and you are located in the United States. We will randomize you to a video delivery algorithm and will record some information about your video watching behavior, as well as the performance of the video delivery algorithm. For more information about this research study, please review the full consent information sheet [here]. Participation in this experiment is voluntary. If you do not wish to participate, you may watch the same videos on [this website].

Our web server will log your IP address, the time of each access, together with a random number that we will use to identify each video session. Within one month, we will delete both the IP address and the time of access, and refer to each session using only the random number. We will store information about each playback, including the media timestamps that are viewed in each video, the portions of the video that are sent to your device, the playback rate (e.g., 1x or 2x), and the versions of your web browser and operating system.

If you have any questions, complaints, or concerns about this study, you can contact Prof. Yih-Chun Hu at (217) 333-4220 or yihchun@illinois.edu.
