Comment on Disney+ loses Dolby Vision, HDR10+ and 3D amid patent dispute

I know very little but I doubt storage space is the biggest constraint on streaming infrastructure- even with today’s inflated prices, they (or their cloud provider) could add a petabyte of storage to each of their servers if they needed to for like $20k each, which is pennies in the grand scheme of things. They probably pre-encode these things anyways to save CPU resources - this isn’t a home Plex server, they’ve gotta encode for tens of millions of different devices simultaneously.
I think the bigger issue would be bandwidth - if you can’t dynamically switch streams you have to either serve them all at once or just commit to one at the start and re-buffer any time something changes.

I am far from an expert, but basically HD10 is a base layer, it ecodes and thus sends HDR data “once” per whole video.
Formats like HD10+ and DV are dynamic, they send HDR (brightness) information per scene/frame over an extra transport layer.
And those layers can be sent at the same time for the tv to use which one it prioritizes.
From the info above it seems the patent is about the way both “streams” of the HDR formatted metadata are combined and transferred over the internet to the display device.
If this is the case, Disney might do some brainstorming on what is cheaper in the long run: Offer both HD10+ and Dolby Vision which is not a cheap license in itself, on top of which comes the license fee from the patent they infringe on … if they can’t find a workaround.
Or, go with a single HDR standard, in which case I can see them drop DV support altogether to save on (expensive DV) license fees.
Regardless of this, I do not think the case is a positive development.
