HDR10 only needs a 10bit output, and the ability to insert the proper frame header metadata, and least HDMI 2.0a tranceivers (which are external?). Everything else is just software.If its not a new SOC then why is HDR10 support limited to the Slim and Scorpio?
They would only needed some small alteration to the existing SoC on 28nm. Or best case maybe it already supported 10bits and all they need is a new HDMI 2.0a tranceiver.
