About Digital Site Licenses
Purchasing a DVD with Educational Rights means that the film(s) on the DVD may only be used for in-person classroom screenings and viewings.
Explicitly excluded is the right for a college or university to internally rip/digitize the film(s) on the DVD, in order to stream them locally for classes and students within the institution. The right to do this may be obtained by purchasing a Digital Site License (DSL) for the lifetime of the DVD (i.e., in perpetuity).
DSL rights allow colleges and universities to locally host and stream the film(s) on the DVD within a closed, password-protected system that is restricted to use by those enrolled in classes on a single campus.
