BERLIN (AP) -- A German court has ruled that online video platform YouTube must install filters to prevent users from uploading some music videos whose rights are held by a music-royalties collecting body.
German news agency dapd reported that the Hamburg state court on Friday mostly sided with Germany's GEMA, which represents about 60,000 German writers and musicians.
GEMA took Google Inc.'s YouTube unit to court over 12 temporarily uploaded music videos for which no royalties were paid.
YouTube has maintained that it bears no legal responsibility for the uploaded content - saying it checks and sometimes blocks content when users alert the firm about alleged violations of laws.
It was not immediately clear whether the ruling will be appealed.
The ruling could be a major blow for YouTube because some experts say millions of videos on its platform could be affected.
