ERA Licence
Recordings of “broadcast” programmes covered by the ERA licence may be made for educational purposes by employees of the University on site or at home, but if at home may be delivered to the University only on hard copy.
Registered students, teachers or other employees directly involved in the students' education can watch or listen to them.
The recordings can then be used for educational purposes within the premises of a licensed establishment.
Registered students (including UK-based distance learning students) may borrow and take off-site a licensed recording on cassette, CD or DVD. As this may reduce licensees' ability to ensure adherence to Licence terms and conditions, ERA recommends that you ask students to sign a declaration to confirm the material will be used only for legitimate non-commercial educational purposes. This does not authorise the making of multiple copies of recordings, for example authorising copying onto memory sticks used by individual students.
Digital recordings stored on-site, e.g. on an establishment's central server, may only be accessed from on-site terminals. A suitable security or password protection system needs to be in place to ensure recorded material is not accessed by students at home or anywhere off-site. Access is limited to within educational establishments unless an ERA Plus Licence is secured to cover agreed off site access.
On-demand services (including podcasts) are not covered by the ERA licence.    NOTE - This does not necessarily mean that they must not be recorded, but that the ERA licence does not give permission for recording them!
