Does NVIDIA Tegra K1 platform support DRMs such as Adobe Access and DTCP-IP?
I can’t find much information on either, but given Adobe’s history with Linux support, I’d be extremely doubtful that they’d support DRM on it, perhaps via the Flash player, but DRM implementations typically aren’t ported to Linux OSes except for a few proprietary stacks. DTCP-IP with Linux would likely be a similar situation.
Regarding closed-source OSes that use Tegra, the odds are higher, but you’d probably be better off asking the original software vendors of each DRM implementation for what platforms they support. Hardware doesn’t have much to do with support for DRM, AFAIK this is mostly dealt with by software and lawyers.
