Hisense will be the first TV brand to introduce Dolby Vision 2 to its lineup. These TVs will be powered by MediaTek Pentonic 800 with “MiraVision Pro” PQ Engine, the first silicon chip to integrate Dolby Vision 2. Timing and availability will be announced at a later date.
There is nothing about backward compatibility.
My best guess is it’ll fallback or include data for DV1 data in content with DV2 otherwise they are really shooting themselves in the foot lol
I would have thought so too, but one would think they would mention something like this in the press release.
