This page contains some advice on licensing and copyright but does not highlight or necessarily include all the legal requirements that may be involved.
General information regarding the licences that the University holds for academic & research purposes is here.There are separate licences for extracts of text/still images, off-air recordings & DVD content, copying of newspaper content etc.
The University does not hold any other copyright licences for the whole institution. Colleges, departments and student societies may need to make their own arrangements to license activities which would otherwise infringe copyright.
Before using or broadcasting any music or video/film content in a public environment you should ensure that you have either obtained the permission to use it, or have followed the appropriate requirements to use it.
In a University context, 'public environment' can be defined as a Public or Open Lecture, or an event which is transmitted online (either via Zoom or Youtube for example).
The University does not hold a PRS/PPL licence - now called TheMusicLicence. It is for users to obtain this themselves if appropriate to their event.
The Open Lecture will have been advertised publicly and the audience will therefore include members of the public.
The presenter should ensure that any text, images or musical content they use is covered by the appropriate license or permission.
Just because the event is held on campus and has 'educational content' does not mean the content is covered by any licences the University holds.
Copyright can be acknowledged at the time of use - i.e. displayed on a presentation slide with the copyrighted material, however this does not replace the requirement to have the correct licence in place.
It is for the author of the presentation to ensure they have permission and licences to use any copyrighted material.
The nature of a conference where delegates have to register in a private capacity means that there can be an assumption that no members of the public are present.
However, a conference audience would still be considered as 'public broadcast' and as such the organiser should arrange a MusicLicence (for example) to respect the copyright holders work if music is used between presenters etc.
If part of the event is streamed live via Youtube, this is broadcasting the content and the nature of the audience is no longer relevant. If the Youtube channel is monetized, then the organiser will be making money by broadcasting copyrighted content.
This requires licensing or may be forbidden, and Youtube may block content or close the channel/account if not adhered to according to it's terms & conditions of use. Even if licenses and permissions have been obtained, Youtube may not allow broadcasting of some content.
There could be the assumption for such an event that all material used is covered by the CLA Higher Education or ERA Licence, since it is specifically an educational event.
Material should be checked to ascertain that it is covered in advance and it should be noted that the University does not hold any institutional licences for playing music or films and licences may still be required for extra-curricular events.
