Why is all this high-resolution media walled behind decoder boxes and DRM? 4k blu-rays have some fairly intrusive DRM as far as I understand, and then there's 4k streaming like on Netflix, which requires hardware DRM to playback on PC.
Consumers aren’t told about DRM. The spec sheets don’t speak about what restrictions are in place. You only discover after the purchase that some capability you had assumed you could do no exists.
E.g. for me I’ve had this twice. Trying to view an HD movie over a component cable—nope not allowed. And second my daughter discovering she can’t use music from a streaming music service in a home video. Both occurred well after initial purchases.
Can you say more about where the DRM applied in this case? I would expect it to kick in, say, if you upload a home video to YouTube that incorporates copyrighted media, but I would be surprised if something prevented you from making a video (say on your phone) that included whatever music playing over speakers.
