Our Video Sources and Licenses
Knowledge videos: They are collected from YouTube and be used as the purpose of education. Because of the well-known problem of visiting YouTube from China, we have to download the video files from YouTube and serve them on our own site. However, we have kept all the information about the authors (YouTube channel), and the source links are also provided to our audiences. If you are the author of some videos and do not want us to serve your videos on our site, please contact us, we will take them down immediately.
Open course: They are mostly collected from the websites of universities and colleges, and some of them are from iTunes U. Most of them are licensed as Creative Commons. We have kept all the information about the copyright owner, and the source links are also provided to our audiences. If you think we have infringed your intellectual property and do now want us to serve your courses on our site, please contact us, we will take them down immediately.
