However, in some classes, streamed videos are used. Basically, enrolled students go to the course website, click on the video required, and see the video (motion, sound, etc.). In effect, it is the same as going to YouTube or similar websites. You don't download the file from YouTube typically; you just see the video in question.
Last academic year, the group described in the article below ordered UCLA to halt the practice and there was a brief episode in which classes were disrupted by the sudden unavailability of such material.

As a result, the streaming service was restored.
Apparently, there will now be litigation over this issue.

Since course websites are not classrooms, the group said, the “fair use” exemptions for educational use do not apply. UCLA has said that since the course websites are password-protected, streaming videos on the site is the same as showing them in class, except far more convenient for students and professors...
