They may not be downloaded, duplicated, recorded, reposted, incorporated into other videos or programs, or presented in talks. They may be shown directly from my YouTube channel for classroom teaching at school or university. And they may be embedded a blog or website provided that they play directly from my YouTube channel and that you link to this site as the source.
