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

I don’t get why HDR+ was removed since it’s an open source format. Was it some sort of patent due to transporting HDR content?

I’m confused about that too.

InterDigital seems to claim that the patent in question is about dynamically overlaying multiple video streams e.g. from ir.interdigital.com/news-events/…/default.aspx

The Munich Regional Court ruled that InterDigital is entitled to an injunction over Disney’s infringement of an InterDigital patent related to the streaming of video content using high dynamic range (HDR) technology. Disney can appeal the decision.

The judgment from the Munich court follows a separate decision from the same court to award InterDigital an injunction over Disney’s infringement of a patent which enables a method for dynamically overlaying a first video stream with a second video stream. It also follows a decision by a court in Brazil, to grant a preliminary injunction in InterDigital’s favor, after the court found that Disney infringed both of the InterDigital patents-in-suit.

What’s interesting is that HDR10 is still available on Disney supposedly. So it sort of sounds like the claim is that Disney is adding DV/HDR10+ dynamically during the video stream… and maybe regular HDR is pre-generated by Disney hence is not affected by the patent. The solution might be to always have multiple pre-generated copies of video before the stream even takes place…that would be a lot of extra storage space Disney would need!

I’m also curious how DV (Dolby Vision) factors into all of that. If I had to guess Disney is dynamically adding DV with HDR fallback as an extra stream in the video, so by removing that you end up with only SDR and HDR10 options… but again that’s just a guess.
