If the problem is about classifier design, I supposed that in the least convenient possible world both the porn and the high culture media were being beamed from Alpha Centauri. Instead of being able to affect the production in any way, all you could do was program the satellite relay that propagates the stuff to terrestrial networks to filter the porny bits while feeding the opera bits to lucrative pay-per-view, while trying not to think too hard about just what is going on at Alpha Centauri and why is it resulting pitch-perfect human porn movies and opera performances being narrowcast at Earth in high resolution video.
