Because H.265 is so much more processor intensive, don't expect a simple firmware upgrade to get your gear to decode it. In fact, that's part of the issue. You need a hardware decoder somewhere. If your new media streamer, cable box, or BD player has it, then you'll be all set (presuming you also have HDMI 2.0 so you can get 2160p/60 and not just 2160p/30). Could a high-end PC decode it via software? Maybe. Could the Xbox One or PS4? Not likely. Everyone loves their favorite console, but remember, this generation's hardware is equivalent to a pretty average PC.
