I don't really know how licensing works for video rental stores, but I expect they must pay some sort of additional royalty (or similar) on top of the price of the physical media itself.
However, I expect that the licensing/royalties for streaming and other digital rental services are somewhat different, since multiple customers can watch the same video at once.
What I'd like to know is, can rental stores transition to being digital content providers by uploading videos from the physical copies they already own for rental?
Here are some particular potential roadblocks:
- Would they have a legal obligation to add DRM?
- Would they need to pay some sort of per-view royalties?
- If they have a rare video from a now-defunct studio, whom would they need to contact about royalties/licensing/etc?
