Is it useful to report a new exploitation form / rebroadcast?

You can certainly let us know. We will then ensure that the information is processed correctly. 

It is not necessary to make a new registration of your work. The original registration remains valid.

Television broadcasters also broadcast content online. E.g. additional videos from a TV programme that you can only watch on their website. You can only receive royalties for this type of online broadcasting if it concerns new content, meaning the video may not already have been featured on television. If the video was already broadcast on TV, you already receive royalties for this through the television playlists.
